TBB Power has been popping up lately on the forum, do you have info on how to get a distributor?

I thought growatt & srne were some kind of voltronic/axpert system albeit modified.

I went from Growatt to Sako. My experience is that my old growatt charges better. The Sako is still serving well though. But I only wish it would give me the growatt efficiency which I experienced.

I will check if there is a firmware update for the inverter.

You can check out their office if your based in Lagos. There contact details below:

To our experts or experienced people in the house,
are all mppt in our hybrid inverters created equal. Are there brands that are known for effective & efficient charging.

I ask because the rate & efficiency of charge I experienced using growatt inverter appears to be better. Any thoughts on this

Different brands like Deye, Growatt, SRNE, TBB Power, Huawei etc use different internal components and charging algorithms for their MPPT. Infact, some brands like the Voltronic/Axpert range of inverters have a known float bug that affects the charging algorithm of their mppt. Some of these issues are fixed by firmware updates but for the most part yes there can be a difference. If your moving from a previous budget tier to a Growatt, ofcourse there is a noticeable difference, however, there are several other premium brands out there too that give the Growatt a run for their money.

jonescosmos:
You got it wrong bro, the problem is that:
1. PvOutput portal requires a 3rd party device to get your data, That makes it not an Opensource Data Resource.
2. How many Nigerians could afford Victron Systems?

Despite the fact that we all need to monitor our devices, the Idea of going RE is to cut down costs of recurrent energy bills, but we end up subscribing to Data Bills to keep up with our devices.

Believe me if the Data Loggers that ships with Inverters and their DataCenters were hooked to PvOutput automatically once they are connected to the Internet, I guess the data coming from Nigeria would have been larger than we see currently.

Somebody asked a simple question, whether there was a data sheet tracking all solar installations in Nigeria and estimated the numbers to be mind boggling. I replied with two resources he can easily check online. I also gave two amongst many reasons why the number of Nigerians on those websites are low, including consistency of ensuring systems are online which speaks to No. 1 and being able to post the data online needing constant connectivity. So, i am wondering where the fight is starting that your opening statement that you decided is " You are wrong" to begin a conversation.

swagifted:
omo, this is huge...i wish there was a data sheet tracking all solar installations in nigeria....am sure the numbers will be boggling

Victron has one called Victron World https://vrm.victronenergy.com/world/ and the other is PvOutput https://pvoutput.org/

Unfortunately, the number of Nigerians listed is a bit low as not everybody is consistent in ensuring their system is connected and online sharing the data. However, its an interesting read.

Polaris1:
You talk too much and your knowledge is mediocre and often misleading compared to some regulars on this thread. Would be nice if you post only what you know in a clear, concise manner. Try not to mix English and pidgin too, it destabilizes syntax flow.

Why nau ?

odimbannamdi:
Please, let's put Valto in prayers. He is seriously sick and has little access his phones

Meanwhile, I got one of Valto's battery (12v 135ah with Bluetooth enabled BMS) for a friend last year, and the guy has really been enjoying the battery.

But for about a week, there has been an issue. Previously, it was cutting off power supply at 30%, probably to protect the battery, and our expectation was that the cut-off period would reduce with more usage. It did reduce to 20-something, but recently it cuts off at 62%, giving just a few hours of use. Below are screenshots of the BMS interface on his phone.

Is anyone experiencing this? And how did you resolve it? The guy really needs an update

Wishing @Valto a speedy recovery and good health. Guy has been making huge impacts in the LifeP04 DIY pack game for a while now.

Juror:
I think you may be overreacting here, the vendors have said he should bring in the item for a checkup, and I believe he has agreed to do so but the client wants him to put an external CC, at whose cost should that be?
You don't even know how much was paid or how much was earned, and it's also a 12V installation.

It would be unfair to say he should bear the cost solely? Especially immediately too, when there's still the option of returning the inverter for a check to see if it is faulty or that's how it was designed to work.

I think my reaction is not out of hand seeing the "excuses" that are already beginning to be formed. My take is that once you agree to accept somebody's money to offer a service even if it is N1, then you are obligated to deliver on that service. I can already infer where you are heading with statements like "You don't even know how much, how much was earned, its a 12v installation". You decided to accept somebody's money, why shame them on top for not delivering a quality service. Can't we demand for excellent service in Nigeria for our hard earned money again. Arrrrrg. Nigeria. I apologize if it seems like i am overreacting but seriously cases like these do not augur well for us as a nation and that is why the solar industry is full of issues. All i am saying is that let's manage our clients well and offer better support. People are more when you make efforts and show care towards resolving their issues rather than this attitude of your on your own.

JoeSef0:
That's about 80k.
I'll be getting the CC out of my own pocket. That's too much for me to cover

You see this statement. This is what gets me angry. This is why a lot of Nigerians have such a high distrust for anything inverter/solar and Kazeem installers adding to it with poor service. After quoting and charging a client for labor and materials. You install a product that suddenly develops a fault NOT due to any user error, and yet are unwilling to go the extra mile to support the client. Most installers have this attitude of once i install anything for a client and i collect my money they can go to hell. Not knowing that an installation is an entry point to continuous patronage and good will that can last for years and bring even bigger rewards down the line. As an installer, you should ensure that materials you buy are original and comes with guarantee/warranty from the suppliers for their products. No client wants to hear that they are on their own when it comes repairs and warranty claims. As e dey pain you now to remove money to resolve this issue, so did it pain the client to cough out his hard earned money to pay you for a quality service. In business some days you win some days you lose. But always try to treat your customers better and try to resolve their issues.

sharks776:
Am trying to buy an extra CC just to keep as a spare incase of emergency. I decided to get PowMr 60a charge controller. But am getting to different quotes with huge disparity in terms of price from Jumia and Konga.

I really can't tell the original

You can also try the SRNE Charge Controller. https://www.srnesolar.com/productdetail/PWM-Solar-Charge-Controller-HC.html

Contact Mr Ugo (HM Solar) 0.8.0.3.449.0636

Price last year was N42,000 (but please call to confirm current price)

temizeee:
agh agh so you’re saying you have been observing uncle @bassdow for a while that he has a fat mouth 👄 and likes to sha type a lot based on his opinion….. no offense

You are a wicked somebori

sharks776:
1. The manufacturing date on the sticker is showing October 2022.
2. Can't determine number of cycles
3. According to the seller, they are telecom batteries.
4. The guy is quoting 850k for the Huawei 48v 150ah and 750k for the 48v,100ah

1. That's great. Which means by calendar age they are not that old.
2. For the Mantrac battery (which i am partial too), you can get the number of cycles from the front screen menu. It will be listed there in the options menu just like the Seplos batteries. For the Huawei, i am not too sure but if there is an app or bluetooth connection you can use, you should be able to pull this information from the BMS. Ask the seller about communication with the built in BMS.
3. Okay. So, they were kept in a cool and well ventilated environment, however, their discharge cycles might be a bit high but this negated by the calendar age and most telecom sites follow basic safety precautions in their installations so this shouldn't a major concern.
4. This is where you need to do your research and compare how much brand new 48v 100ah & 150ah batteries are selling in the market right now compared to the asking price for these used ones which still have a lot of life left in them. Also, calculate how much you need to spend for the same capacity in lead acid batteries without all the benefits that you get from LifeP04 and then finally look at your budget. This is individual to everybody but as you can see from the comments of people asking for the contacts of the seller, many consider it to be a good deal.

sharks776:
Hello Good people,
Please does anyone has any experience using this lithium batteries (they are used)
The black is Huawei and white is mantrac. They are being offered to me as used.

Both Hauwei and Mantrac are reputable brands. However, because they are used, there might be some argument as to how much life is left in them. However, being LIFEP04 batteries, they will still have a some juice left in them and will serve you better than some brand new chinko lead acid batteries in the market. Some questions you can ask the sellers:
1. How many years old are the batteries ?
2. What is the number of cycles that the batteries have been discharged ?
3. What were the batteries used for ?
If you can get some satisfactory answers to these and the price point is right, i see no reason why you cannot go ahead and purchase. Bear in mind though, that being a used product, you should have some lower expectations in terms of performance. Certain LifeP04 brands like SRNE advertise an 80% remaining capacity after over 6000 cycles of charging and discharging their 5.12kwh batteries (51.2v 100ah). You can research more on the model number of these batteries and see their spec sheets. But all in all as long as they are in good condition, i will take them over a lead acid battery any day.

kristien4:
Okay thanks. Just wanted to know if we were talking abt thesame thing, because all this sellers, truth no dey their mouth.

Gennex Tech is an authorized and dealer and reputable seller of Jinko, Canadian Solar panels and Trojan Batteries. We have listed them here before on this forum as a genuine source of solar products with warranties. However, as a earlier stated, certain premium brands command a higher price point compared to the alaba chinko products that many often resort to. If the product is within your budget, please feel free to go ahead.

FEGEITOK:
Those of us who personally import solar panels from (Lagos to other parts of the country) what reliable means of logistics do you use?

Reliable and cost effective because I got a quote of 20,000.00 from the company to the loading point in Lagos and another 20,000.00 to Abuja and I consider it unreasonable to pay the same amount within Lagos as I am paying to Abuja.

The route is Lagos to Abuja

Why go through that long process when you can get from dealers in Abuja ?

JA Solar, Jinko and Longi all have reps in Abuja that can supply you here. If your in the DIY Telegram group, send me a DM.

swagifted:
on instagram i saw a quote for 529k for high voltage and 502k for low voltage...both 5kva..is it good for 24/7 usage? am really considering it

Why not buy from their authorized dealer in Nigeria HM Solar ? His contact details have been shared here in this forum.
The product is of good quality and comes with warranty from the dealer.

Bgee77:
Pls I want know if I can use wind turbines on normal inverter,like Felicity IVPM10048 ?

Short answer, NO !!!

abbeymighty:
Good morning house, please i which is better ways of connecting 4pcs of 300watts solar panels , is all in parallel or 2 series and parallel. thanks in anticipation

.
It depends on what your system voltage is and type of charge controller you are using. But best practice you connect them 2S2P. You connect 2 in series and 2 in parallel. This gives a good balance between the open circuit voltage and short circuit current.

GuestJoe:
Hello Sir,good day.
I have been wanting to thank you for the updates you usually share here to help everyone who comes across this page. Through your resourcefulness,I was able to get contacts and links to approved solar panels and batteries dealers in Nigeria few months ago.

Once again,thank you. Please,I will like to contact you for your advice on my next installation which is primed for next week.

Thank you in anticipation Sir

Thank you for the kind words. Just helping out in promoting the Solar FTA gospel. Have sent a message to your profile.

TechGeek777:
Thanks, I contacted them last month and was told 400+, efficiency is low and from research I did on similar inverters(Via Google Lens scan) was 100w idle.

Okay. Another recommendation will be the Onyxline of inverters. Checkout the Grovolt Amuma Hybrid Pure Sine Wave Inverters
https://onyxline.com.ng/product/grovolt-amuma-hybrid-pure-sine-wave-inverters/
It has 95% efficiency with 90A charging capacity with a built in transformer. Don't know the low idle power consumption and price currently.

Lastly, you can also the Must Energy Power EP3000 PLUS Series (4-6KW)
https://www.mustpower.com/product/ep3000-plus-series-4-6kw/
This also another low frequency inverter with inverter efficiency of 95% and power factor of 1. 35A charging current with idle consumption of 100W(+-20). Wishing you good luck.

TechGeek777:
Thanks, they don't have 5kva Riio/Riio Sun for a long time now, even chatted them few days ago.

Below are the current prices and it's out of budget for now.

3kva-24v Riio(Non-hybrid) 459,000
3kva-24v Riio Sun(Hybrid) 584,430
4kw-48v 760,000

Okay. Another one to look at also is the XtraPower LF Series Hybrid Inverter XTLFH1-6KW
https://www.xtrapowerng.com/xtrapower-hf-series-hybrid-inverter/
However, it has a lower power efficiency rating 85% and no data on idle consumption. But it has local support and warranty.

TechGeek777:
I am highly convinced this is due to the numerous fake 13A socket sold.

I went to purchase some electricals yesterday, this includes two original A & B tech 13A socket.

During purchase I asked the man to tell list of various prices, it ranges from (400, 600, 800 & 1000) respectively.

I went for the highest they have 1000(A & B tech), because it will be installed in Electric Hot Plate location.

I believe most naija would go for 400 category.

Also bought two 2P 100A Knife Switch (I already have two A & Bt quality change over installed but these are for my solar project) they brought these categories 1500(Orange color), 2000, 4000, 5000 & 6000 respectively.

The 5000 is good but rated 380v, while the 6000(D & GT) is better and rated for 600v, I went for 6000 category.

Most Nigerians would go for the regular orange color (1500).

Most times it's better to buy once and forget about buying in the nearest future.

Meanwhile am still looking for good 5kva hybrid/non-hybrid transformer based inverter with Idle consumption less than 50w, efficiency up to 90%, AC charging current b/w 40-60A and less than 450k.

Checkout the TBB Power Nigeria RIIO 5kva Inverter Charger. I think it ticks off everything on your list except maybe the price which you will need to confirm from them.

TechGeek777:
True, but some brands like Felicity & TBB offers warranty that covers human errors to great extent(This they did without even asking what damaged the inverter but proffer solution to it just to protect they brands.

I understand some users can abused inverters to utmost extent.

Maybe, you should have resolve the shortage of wire that wasn't replaced.

Bro, try to protect your image especially *ONLINE* eh get why.

Have you thought of why banks and well established enterprises *ALWAYS* try to pacifier customers trying to constitute nuisance in they premises?

See Mohbad matter for instance, Naira Marley lost thousands of followers even before people heard his opinion, also it will take something beyond human to revive his career, that he has built.

Internet matter too powerful, You fit dey come out for minister position tomorrow and your opponent go pay people to dig shit from your past.

Caution is needed to protect ones image.

Make una try resolve the matter peacefully abeg.

Don't waste your breath. It's this internet anonymity/distance and feeling of impunity on issues that gives people the right to act and behave anyhow to their customers rather than engaging them to find an amicable solution. And as you have said, the internet never forgets and a cursory google search of your username will bring up such conversations. For someone working in the sales & service industry, its not when things go right that your all loving and respectful to the customer but the true test is when things go bad. Broken items during shipping, manufacturer defect/warranty issues, sub-optimal performance of item etc. While of course nobody can hold you responsible for customer behavior and inappropriate use of the equipment, always try to find a solution for your customers and they will be singing your gospel everywhere. This default confrontational attitude that we see in a lot of cases reported here tells you all that you need to know. These guys are only interested in collecting your money and your On Your Own if anything else happens.

TechGeek777:
People are reading, without calling names, installers and marketers, ALWAYS do everything humanly possible to satisfy your clients.

Even if dispute are resolved, the internet never forget indeed!

To all users out there, for inverter if you don't have the funds for big brands like Victron or Deye, and you are keen on warranty, go for TBB(Far better than most brands with 2 good years warranty) or go for felicity (same 2 years warranty).

Any other brand should be Zinox iPowerPlus (with 1 year warranty). This is Axpert clone which is also a good brand.

It's why i never hid my dislike for resellers that rely on poor customers knowledge to exploit them out of their hard earned money by providing subpar goods and services. I am all for sharing information to break this vicious cycle so that customers can make informed opinions before parting with their money. And we if your earning legitimate money in this country, its doubly painful when you remember the blood, sweat, pain and tears it took you to earn them. Having said that and taking no sides on the current issue ongoing, i hope this serves as a general reminder to people in this forum patronizing online resellers on the potential issues that can arise. There are several reputable dealers/distributors/resellers with shops, verified addresses and online presence that one can safely purchase from with peace of mind and guarantee/warranty. As soon as your money leaves your account, your left at the mercy of these online sellers and these are examples of such issues. Fool me once, shame on you; fool me twice shame on me. The fact that people have to resort to screenshots of whats app chats and voice notes to gather incriminating evidence is too much jare. On top my money o. For the people that continue to patronize these people here, personally, you will get less sympathy from me. For the online resellers that continue to keep on spamming the thread day in day out with their products and treat their customers anyhow when money has entered their account, your time will also come.

zeestone99:
You are still saying the same thing I'm saying but with plenty English.

You can't do continuous 5kw. Hence pf is not 1. There are conditions to it. People need to know so they don't go with the mindset of doing 5kw on 5kw. Hope u get

There was some wisdom in the plenty english nah. No inverter subjected to temperature can do PF 1. Just because the chinese no name brands don't put in their inverters doesn't mean that they don't derate. As the temperature rises in the inverters operating environment and under load, it will derate its output. There is always a loss in the energy conversion of DC to AC. The law of physics is universal. It happens to all inverters. But Victron is being more open by telling you exactly how and at what temperatures it is able to output its capacity. The issue i guess was you making Victron to look like the only inverter that derates its ouput instead of aspiring it as a normal convention that applies to all inverters and not just victron.

Guys, for those who can attend the annual Nigeria Energy Conference is starting today at Landmark Hotel, VI Lagos. It is usually an opportunity to meet directly with suppliers, learn what the new trends in technology are, meet international suppliers who also come to the conference yearly, and also know the direction of government policy with regard to renewable energy.

I could have posted the link to access it but I am not in any mood for one BOT to disrespectfully ban me, so I suggest you google "Nigeria Energy Conference" and preregister to attend if it is something that ticks your fancy.

Those who attend can also share with us whatever new innovations are in the pipeline so that we can as solar enthusiasts position ourselves to be at the forefront of implementation.

I have been reporting and posting this on the thread & DIY Solar Telegram group for a while now. I attended the conference flying in from Abuja for three 3 days. The conference this year was even more massive and had a lot of Vendors in attendance from Fronius, Victron, SMA, Anern, Felicity, TBB Power, Xtra Power, SRNE, etc. I will post some pictures from the event soon. The conference has had maximum exposure as the current minister of power Mr Adelabu was at the event. I have also been seeing their sponsored posts on linkedin, youtube and online.

valto even as much as i love lithium battery. This customer de on a tight budget. I 4 go 4 24v system but na waste of energy n resources on top a 1000w to 1200w load continous..

Your customer is on a tight budget and he is going for Full River AGM Batteries from Idyllic ? Full River are the Grade A of Premium Lead Acid AGM batteries and cost quite a penny on par with LifeP04 cells. The point Valto raised is instead of spending that amount for a number of batteries that you can max discharge 50%, why not buy LifeP04 that has more usable capacity to use. My last quote in 2020 for their 12v DC-260ah battery was N205,000 each. Only God knows how much they go for now.

Good afternoon gurus in the house,

Please can anyone give me a list of good and reliable inverters, batteries, inverters and solar panels.


Thanks

speed isn't everytin ?.. bros abeg na autocorrect write dat statement? E b like u never experience good Internet speeds

I dey his camp for this area specifically latency. What's the essence of the speed if the latency is so high ? Na the thing wey kill satellite internet be that before the coming of Starlink. The main selling point of Starlink is the shorter latency being closer to the earth thereby giving higher speeds. For people who do a lot of online gaming, VOIP, Zoom Meetings etc latency is crucial. Once speed passes one level, it doesn't really matter. 5G, 1Gigabit Links etc. Netflix recommends min 25Mbps to watch 4k content. Na quality over quantity that's the main thing he's pointing out. And for FTTH, that ultra milisecond of latency ensures that your traffic travels quickly and any application or inputs send over is translated quickly in realtime.

gadgetplanetng:
Na wa

Baba, go back through the pages of the thread and see the list of LifeP04 vendors on Ali Baba.

Contact them and negotiate a price. Some can ship directly to Lagos DDP (Delivered Duty Paid) and you pick at the shippers warehouse or they ship to a freight forwarder of your choice who will handle shipping on your behalf. You use your dollar card to pay using Ali Pay and that's it. The alternative you contact any of the lithium sellers here and buy from them with their additional cut on top. Choices dey.

FEGEITOK:
can you share their name?

although it maybe a location dependent thing.

I have clarified in another post why I went this route

Layer3 and their service has been good so far. They use Ubiquiti for their network devices which nicely integrates with my UDM PRO and other devices.
