Please for budgetary reasons, I am thinking of getting a 5KW SRNE inverter with 5.12kWh Lithium Phosphate Iron battery and 5.5kWp Solar panels (10 panels x 550w). My home load is a 2HP LG Dual Inverter AC, One 55 inch LG flatscreen, 2 laptops, 1 video game console, 2 standing fans, one fridge, one water dispenser and 12 energy bulbs. Please how can I efficiently manage the load application on the inverter system to prolong its lifespan and when during a 24 hour period can I switch on the AC, what appliances do I need to switch off when using the AC and how many hours in a day can I use the AC? Kindly advise please. Thank you.

The two key words you have used here, "budget and management" do not really corresponding with the energy demand listed here. Lol.
I will advise you reduce your loads so that you will be able to manage the entire system effectively.
AC can come up by 12 noon on sunny days and go off by 3. If you mistakenly keep the AC on till 4, part of the stored energy in the battery would be removed to support the running of the 2hp AC and the stored energy left in the battery may not sustain you till the following day depending on your night loads.
Though the watts of the fridge and water dispenser are unknown but I would advise you should keep them on over night.
Try and reduce the the number of the energy bulk at night.
Whenever the weather is not friendly, do not think of putting on the AC. I hope you have done enough research on that inverter.

That's another thing. A friend, an installer gave someone a quote for ₦2.5m for some solar solutions, the client laughed at him and said if he has ₦2.5m that he would be out of the country where there is 24/7 power.

Crooked installers get the job most of the time as compromising on quality means nothing to them. Eg using a 40A PWM to run a 5kwh PV set up. Lol

He has money to buy 5kwh PV set-up but he didn't have money to buy a good Mppt CC. It's well!

Simple...find soldier man take visit the guy. Since legally go give u stress...

This sound very funny
Will going to his shop with army to beat him solve the problem?
Everybody may not be me but believe me it works for me. It has been working and it will continue to work for those that believe.
If someone deceives me and collect my hard earned money, he will and can never use it for something meaningful.
The law of Garma is real. God can never lie.
Though it's very painful, but we should learn to leave some battle for God.

Good morning and happy Sunday to y’all great people out here🫡🫡🫡
I want to narrate my horrible experience with a guy known as BlueCross in Eleyele Ibadan right opposite Anwar’u Islam Grammar School, it will be a quite long story but I will make it short as much as I can.
Met him around June 2023 on jiji and we talked about doing a solar solution that is capable of charging my gadgets only, although the post of his I saw on jiji states that the solution can run a TV for 5hrs and it’s the same solution I requested for. His guy came around and installed it but then with just my 33W charger, the solution will trip off after 2hrs of charging when the sun already went down of which I contact him and made him realize this isn’t what we agreed on but I let it slide.
In October, I saw his whatsapp status one day with 10kwh battery just built by him so I said I would love half the capacity of that which is 5kwh I believe as I want to make use of it to run freezer for ice block business.
He gave me quote and I said he should take the one I had before and then I’ll add funds to it which we both agreed.
He said he will deliver within two weeks max and I paid him but more than 2months after before he came to do the installation giving me excuses of not being able to get his hands on the inverter he wanted to use for me.
Eventually he came and do the installation and after charging the battery full then I plug in my 110W freezer alone from exactly 4:30pm to run the test and behold the battery trip off at exactly 11:46pm in the same night which means it only lasted 7hrs 16minutes.
I contacted him and made him realize this can never be a 5kwh battery as there is no way it will only lasted for 7hrs as I expect nothing less than 30hrs at least from it.
Does anyone here has a police connect in that area or close by?
I do not mind spending my last kobo to make this guy realize the fraud that he is because I am frustrated by all of his doings.

I will advise you handover everything to God and move on...
Good name is better than riches and I believe God will provide funds for the replacement.
You may meet me via my contacts and let me see how I can assist.
Please, move on....

I need this Powmr charge controller. Let me know the price.

easyyoke:
Anybody please? Or all Charge controllers sold in Nigeria, none of them get bluetooth app?🥺

Go for Victron with Gx Controller, otherwise only local bluethooth.
Midnite Classic Charge Controller have a LAN Ethernet port that can be connected to a WiFi and there is a good third party android app (Graham) which connect from the phone.
I used Morningstar's TriStar Mppt 60 CC to receive live view through router connection to my laptop. 600v and the new GenStar also work for it. No app is needed. Just use your favorite browser.
Another option is Schneider with Insight Local (WiFi or Ethernet)

Trippledots:
So I did a test today with a victron quattro and got about 61% efficiency. I've done this before though and had to repeat it to be sure I was not making mistakes.

This confirmation led me to do some research and I found this....see pix attached.

In summary,these "cheap chinese knockoffs" as some people like to refer to sachet inverters, are not bad at conversion efficiency, and basic protections.

This is very nice. Thanks for the analysis

Good Morning Everyone, Happy Easter to you all.

I recently just started the green energy journey with a few mistake and it's been fun.

I joined the Felicity crew cuz my friend was using their products but would have gone with Growatt or Epever if I knew what I know now. (No regrets).

I'm a smart home Enthusiastic and a sucker to stats and monitoring.

My current set up is - Felicity 5KVA inverter (IVPS 5048 ) + Felicity 80amps MPPT + Felicity 5KWH 48v Battery (LPBF48100) + Jinko 435w panels x 6

I found a couple of ports on my inverter (RS485 & RS232), charge controller (RJ45) and batteries but cant get them to communicate with each other. Is there a way to read information from these ports wirelessly or access them remotely.

Please I would be happy to learn. My thought is that those ports arent there for decoration but there's very little information about felicity setups and remote monitoring online.

Please help me or point me in a direction to follow. Would love to read the power generated from the panels and add the stats to home assistant.

If other methods suggested here fail, then you have to contact the Felicity factory engineers and let them send you the firmware that will enable your system to communicate. Getting them to communicate will help you to integrate the monitoring into the entire system.
Yours is 5kwh but I was told that the 15kwh works with Li-BMS RS485 protocol 12. CAN doesn't work.
I learned CAN protocol can communicate with C35D and C358 of the inverter software.
You need to know your inverter software.

Which wire do you recommend I use bro

Please look for a good installer to re-arrange that system for you. If you're not careful, the so called "installer" would collect money from you again and buy the third charge controller. This is not the right time to waste money. Please, try and remove that naked wire across the two battery terminals.

gifted65:
Please I need help.

I have 300 (3) and 250 (1) solar panels
100 lead acid battery (2)
Inverter 3000w sachet

Because of my 12v, so the the installer add another pwm cc to the existing powr mppt because he said the mppt could only take 3 panels.

During the day, i still don't have sufficient energy to power 120w freezer and two ceiling fans with 2 tv

I'm struggling to understand why he used pwm and mppt charge controller.
Please, change that short naked wire across the two battery terminals. It's dangerous...

RickyM:
Delivery date shifted by 24hrs he said.

Please, relax your mind. You will get it. Maybe there is a delay on the road. Just call him and find out what actually happened.

- Who has experience of this two LIFePO4 batteries Downice and SVC

No popular review yet. You might go for it and give us the review.

adibo:
Also, I am caught in two minds, between buying a 2.4kva 24v mercury hybrid inverter and buying a 1.5kva 12v Mercury hybrid inverter. I need it for lights, charging of laptops and phones, 120w fridge, 240w washing machine and 32 inch smart TV. I heard that 24v inverters are more efficient than 12v inverters. Also, I am just considering buying the 2.4kva in order to have extra space for more load in future. What is your advice?

cc Obnoxious2001

If you're working on budget, go for 12v 1.5kva system. Use washing machine when the sun comes up. Use your freezer during the day. Your accumulative loads to be on the battery at night are not up to 250w.
Just make sure the correct wire gauge is used and you will enjoy your system pending when you have fun to upgrade.
Na to see light to power the basic things for house a lot of people dey find now.

Sachet inverter de get credible data sheet? I'll check

Please, drop it and let's compare with others. I have similar inverters, though from different companies and I'm yet to hook them up for capacity test.

adibo:
Thanks for your response but it is too technical for me. Please break it down for me

4 pcs of 150wh giving 3.6kwh at 50% dod for 580k is better than 2 pcs of 220ah giving 2.64kwh at 50% dod for 594k.
A higher voltage system would always perform more efficient than the lower voltage system.

adibo:
Good morning, I want to get batteries for a 2.5kva or 1.5kva hybrid inverter. I just noticed that two 220ah batteries give a total of 440ah at 594k while four 150ah batteries gives a total of 600ah at 580k. By my local man logic, the 150ah option seems better to me cus I get about 160ah more battery capacity. Pls, those who are experts, is this my logic correct and can I go for this 150ah option?

Your analysis may be wrong. 2 pcs of 220ah will give you 2.64kwh dod and 4 pcs will give you 3.6kwh dod.
Choosing between 24v system and 48v system will depend on your loads and your budget.

Trippledots:
My sachet inverter when pulling about 600va AC load, draws about 1kva DC power. That's about 60% conversion efficiency. Ambient temps was in the high 30°s though.

Has anybody actually measured their DC to AC conversion efficiency? I'ld like to know what they got. 🤔

Can we see the datasheet of this inverter?

nicodemusic:
Good morning house.. Sorry to bother you guys.. I noticed these ports on my inverter and got me curious what's it's used for.. There also one like this on the charge controller..

RS232 and BMS/RS485

Thanks

Communication ports

Shld i say overload or plugging something too heavy into the system


But the issue now is I disconnected the battery and other wire connected to the battery nd took the inverter for repair

After repairing
I connected all the wires back to the battery
But my charge controller didn't ON only inverter working

Sorry about the ugly incident. Give them the charge controller to check it for you.
This is one of the reasons we should protect our investment via fuse, breaker, over voltage/under voltage protective devices.
Just this morning as I was trying to connect a customer's battery to my system for testing, a positive wire mistakenly touch a negative wire and there was a very big spark. The next thing I noticed, the breaker between the inverter and the battery trip off, even when the pv and the inverter were already turned off. The inverter input switch trip off as well.
When I finished the connections, I switched them on and everything was ok.
If the system was not well protected, probably the inverter would have received a hit.

Abbeyb1ack:
So I finally disconnect my inverter and took it out for repair.....(nt knowing dere are steps and precautions)


I reconnect the inverter back but my charge controller no ON

I called my installer....he said he will get back to me

I just hope I neva spoil another tin

If it was just the overload that shutdown it down, everything including the charge controller should turn on when you remove the loads.

Trippledots:
E de bro. Like last week sef.

If the seller doesn't open up to me on why he's selling 12v 200ah/220ah LA battery at that price, I would be scared.
There are a lot of used batteries and other appliances in the markets that are well polished and packaged to look like new.
At this critical time, buying products from a known/reliable source that's willing to take full responsibility of the products throughout the warranty periods is what we need.

mvphenryeto5:
Why is 24v 100ah more costly than 12v 160ah?

Because the 12v 160ah was an urgent sell. Lol

redgem:
But if price of dollar should go up, you'd still sell old stocks at new price right?

Yes Sir. It's a win and loose situation.
Most of us bought goods some weeks back when exchange rate was very high and some of those goods have arrived. What do we do now?
The market train is unpredictable, especially in Nigeria where exchange rate decides most of our business transactions.
If the exchange rate can remain at a lower steady rate for at least two months, the price will automatically be adjusted downward.

jidobaba:
This is a defacto sellers hub but there was a time people would join funds to buy directly (cheaply) from China.
I almost bought Alaba fake panels even more expensive than Fouanis Jinko(plus free delivery) right on this thread.

The shipping route was narrow then, it's wider now.

mctfopt:
Oh yeah, but old stock must be sold before the review

TechGeek777 is indirectly telling us to reduce the price of our products.
He doesn't want to open up so that he won't offense us

There's no how you can enjoy a used sealed lead acid battery cos you don't know how it was used, it might have only 20-30% efficiency left, to enjoy Lead acid you have to buy it brand New from reputable brand

Not totally true Boss.
You can buy used sealed or tubular battery from someone you know to have a good maintenance culture and still enjoy it for the next three years or more.
Bigrovar sold his lead acid to someone after using it for about two years. Last year made it two years or more since the person bought those batteries from him and the battery was still waxing stronger.
When he wanted to sell his panels for upgrade, we were rushing to buy them.
I sold my LA batteries last year after using it for about two years. The person that bought them is still thanking me till today.
Submission: If we want to buy used products, we should verify the source and make sure the owner has a good maintenance culture. This is the only way such products will last for us.

I need 1000w 12v inverter that's compatible with lithium battery

TechGeek777:
QUANTA 200AH TUBULAR BATTERY is 235,000
https://me3energy.ng/quanta-200ah-battery-tubular

Lithium is still better.

This could be an old price.
What makes lithium better at this price?

nicodemusic:
Thanks a lot chairman.. I also noticed this.. I shall return it to 100% immediately..

Unfortunately, I'm yet to find a way to adjust the charge settings on the inverter.

Pls help me confirm if the other settings on the cc are good.. Bulk, float voltages. Thank you for your immense support

I suggest you reduce the absorption to 27.6v and drop the float at 27.2v.
