Abeg what would you call severe case of voltage lag? My battery only lags when I turn on my air fryer. The inverter load rises to like 30% and voltage drops from 24.9V to 23.2V. Once I'm done, it rises back to say 24.8V

.
Your illustration on the performance of your battery once load is applied is called voltage sag. Those ones with severe voltage sag may not easily return to the previous voltage when the placed load is released, though still depends on the running time of the said load.

With all the rules duely observed, if lead acid battery can last for 5 to 6 years with lifecycle of about 500 to 800, then lifepo4 may get to 15 years under the same condition with lifecycle of about 2000 to 2500.
I'm waiting to see how many years my tubular will stay alive too. The highest power drawn from my battery is 30%. It's about a year now and I've never top water before.

Does anyone have DC and AC contactors for sale?
Either Schneider or CHNT is needed.
Price and contact needed.

Who has EpSolar Epever eTracer Mppt CC 60A 150V should drop prcice and contact.

Valto:
in that order

Thanks sir

mahkanjuh:
Please house, kindly recommend cheapest AVR for freezer and TV, low budget and efficient. Thanks

I prefer the word low budget.
We should always be extremely careful with cheap products, especially electrical.
While praying for the best of our investment/rest of mind, we also do not want to put our lives and that of our loved ones in danger.

1) Epever Mppt CC 150v/60a.
2) Srne Mppt CC 150v/60a,
3) Powmr Mppt CC 190v/60a.
Please, choose the best two for me from above that can either charge lead acid battery or lifepo4 battery.
Thanks

Hello people. I have the following for sale:

9 x 335w Yingli (Black cell) Solar Panels. I purchased the panels exactly 3 years ago (November 2019) from Yingli directly from Yingli's office at Allen Road Ikeja. I used them personally for my home setup. The panels are in good shape and the reason for selling is due to an upgrade to my system. I am upgrading to a higher-capacity setup.

I kept online logs and records of my solar setup so you can actually see the historical performance of the panels (3kw total power) on my solar monitoring dashboard here http://energy.openculture.org.ng:8080/dashboard/view?id=48 (The panels are still in use as I write this)

The highest performance I ever recorded from the array is 3241w and this was sometime this year. (Screenshot attached)
The total price I am selling the array is 450k at the cost of 50k each. I intend to sell them all in one go.

Location is in abuja and logistics would be handled by the buyer.



The panels are in great shape and
+2348075150964

The major issue is the logistics as I'm not in Abuja.
I would've loved to have them in Uyo, the Akwa Ibom State Capital.

From my findings, felicity hybrid inverter with Rs485 doesn't communicate with lifepo4 battery via Jbd Bms with Rs485 module.
Which other easiest method can one use?
I guess Raspberry Pi could work but it seems to be a long process with extra cash involvement.

Check this out! https://a.co/d/gSh2Ai9.

Does anyone have something like this
for sale?
It might not necessarily be exactly this type but must be Oil Based battery terminal protector/Anti corrosion.

Thanks for your advice

Please, how safe is binance?
I want to buy dollars and drop in that platform for trading purposes.

jonescosmos:
Was working till this year, CBN limited foreign debit on Local cards to 20K from 100K monthly, from 20K they suspended it indefinately.
Foreign transactions on local accounts are only possible on platforms that have Nigerian Payment Gateways now.
For Amazon, you will need a domicilary card to transact.

Most of the USA made products are found in Amazon.
I hardly find them in Jumia and Konga. Is like Jumia's and Konga's concentration is in China.
Very bad.

Has anyone here make purchase in Amazon using naira card?
I was trying to purchase an item of 10k but the payment was declined.

Please he reviewed and gave me the quote above. Please, your inputs will be appreciated.

Someone suggested previously here that the installer should put the names of various components he intends to buy for you.
You may still come back to seek help and it may be too late then.
I suggest you get everything right from the beginning so you can enjoy your investment.

earthrealm:
Ok, most smart hybrids will throttle the current if its beyond its max spec, its usually exceeding Voc that causes outright damage.

Dep3nding on your risk tolerance, you can try 7s2p and see what happens. The 134amps you calculated wud only occur at optimum inclination and sunlight...which in real life rarely happens for longer than 5mins bursts.

If you wanna play it safe, just do your 11s1p and call it a day, or alternatively if you want to maximize everything consider buying a cheap standalone cc like powmr and 2 more panels. So u run 3s1p on the cc and 11s1p on the hybrid

The alternative idea seems good but instead of buying another standalone CC, can my Morningstar Mppt CC with 60A max input current, 150Vdc max input voltage with operating voltage range of 10v to 72v handle this job?

Namzy:
I will reconfigure and make sure it doesn't exceed 450v. Your panels can exceed Voc on some certain cold days so having them near 500v is also risky

Thanks for drawing my attention to this.

Thanks everyone for your advice.
I'll go for 10S1P configuration.

Oshomo12:
First thing first, check your mppt voltage range before taking suggestions. Plz do this first.

The range and every other parameters has been confirmed and stated here in the previous page.

durodee:
Yes to the question.
Also note that there is a reason National grid transmits long distances using HIGH voltage: there is less energy loss and also affording the use of thinner wires as the case may be. So I have a basic principle with high voltage hybrid inverters. I will ramp up the voltage as high as I can first before thinking of parallel setup. Just be careful you don't break the voltage ceiling. If you break the amp ceiling, the Cc will just cap it at its capacity and continue working. If you break the voltage ceiling, then................
In extremely maxing out the capacity of equipment just remember that most times, the benefits does not always outweigh the risks.

Thanks for your advice sir

earthrealm:
Guess you didnt plan it properly from the get go, i mean the voc issh vis a vis the hybrid panel layout. hybrids perform best if the incoming Voc are above 280v. in one of my installs, am running 7s2p 330w panels with Voc of 43v.

i think at this late hour, you have 2 options

1. reconfirm your hybrid limits, and consider buying 2 additional panels, so as to run 7s2p

2. sacrifice 1 panel - sell or keep it aside...and run 11s1p with the existing panels you have already

The hybrid limit has been confirmed as stated in the previous page (120v to 500v). 7S2P x 450/48 is 131A which is greater than the Max Mppt charging current of 100A.
11S1P will give out 113A which is in considerable range as losses may step it down to about 95A.
Fortunately, I'm yet to buy the additional panels hence my reason for asking all these questions. I've bought the 5kw hybrid inverter already and I'm planning to buy additional 450w PVs to add to the existing 9 pcs of 450w before going into upgrading proer.

jonescosmos:
I would recommend you give us your Vmp and Imp also, because 49.3V x 11.6A /=/ 450W (/=/ means "is not equal to" calculations has to be fine for you to get it right. More so, do not hook up 12pcs of 49.3V in series to a system of 500V MAX, you might fry the system.
However, from all indications, a 6s2p might be the best choice for you.

Vmp is 41.5v
Imp is 10.8A
Is 10S1P better than 6S2P interms of waking up the CC early and sleeping late?
Downside: With my existing 450w Pv, I may be finding it difficult to really get a perfect setpoint as I'm struggling to push my array close to 6kw limit just to accommodate day time loads and fill up my battery at the same time.

durodee:
6S2P. The voltage range of your MPPT means the panel Voltage must reach 120v for the CC to wake up, best voltage range is usually stated on the manual but most times around about 300-400v. If you use any configuration less than 6 in series, then your harvest will be poor as your CC will wake up late and sleep early.
By the way you did not include the Amp of your CC to help calculate the total number of panels it can accommodate.
Selah.

I've not checked the voltage range in the manual yet but if it's in that range, do you suggest I should go for 10S1P in order to arrive at 493V and 94A?
Mppt max charge current is 100A.
12pcs/6S2P is 113A.
I think few losses from 10mm cables could bring it down to probably 93A.
I've done 84A with 60A CC max charging current and 3S3P x 49.3Voc = 148V going into Max Mppt CC of 150Vdc with 6mm cables before. I was relaxed because I knew there would be greater loss due to the 6mm cables.

TechGeek777:
ERA SOLAR 450W MONO = 130,500, this is the current price I got today from Techland Solar from their updated pricelist not same with the outdated one on the website

I hope they're trusted sellers.
Please, drop their contact.
Thanks sir

Looking at the harvest/production aspects of the PV, assuming the PV is well positioned and putting losses, external shadow, surface obstruction (birth droppings) and electrical issues into consideration, what are the advantages and disadvantages of 3S4P, 4S3P, 2S6P, 6S2P?
I'm planning to pick one of the above configurations but I don't know the best one among them.
My 9pcs of 450w Era PV (3 pcs to be added making it 12pcs) has Voc of 49.3v, Isc of 11.6A.
My 5kw inverter has PV Mppt Voltage range of 120v to 500v.
Max PV Voltage is 500Vdc.
To be connected to 15.5kwh LFP battery.

Please, what's the current price of 450w Era Pv?
I'm hoping to get three but I need to know the current price first.

Inverter users in the house? Plz how long averagely should a 1.5kva inverter and 220ah battery power a 50w Lg tv, 5 led bulbs (50w altogether), 1 ceiling fan (100-120w) and a Bluetooth speaker (60w)? Please advise or how long does your inverter last with just one battery on the average?
I notice my battery indicator starts reading from 12.5 and immediately drops to 12.2 after full charge when napa light goes off. Please is this normal?
My battery is mpower 12v 220ah and 1.5kva Icell X2 series inverter.
Also, i have 4 150watts solar panels connected but once it's evening arnd past 3, the battery doesn't seem to charge by solar again.

From my observation, your battery is either often abused or not regularly fully charged due to the huge loads on it.
Your battery can approximately power the stated loads for about 4hrs 30mins putting 50% dod into consideration. Unless you depends on grid for the charging of the battery, 600w pv can't be sufficient to fully charged the battery while powering loads at the same time.
I advise you shut down the loads, charge the battery to full first, allow it to settle down for 1hr or thereabouts and then get a voltmeter to check the voltage reading of the battery. If you get 12.6v to 12.8v as rest voltage, then the battery is in order.
But try not to place such huge loads on a single battery if you really want it to last for you. 100w loads on average is ok. Try and reduce the bass of your speaker as well.
Best of luck sir.

Hello house please what is the next best Hybrid Inverter after Deye?

Or a list of good Hybrid inverters one can buy if Deye is too expensive?

You may consider Growatt ES but I guess idle power consumption is up to 60w for 5kw 48v.
If you're working on budget and 5kw 48v system is your target, then I'll advise you grab one Felicity from Jonescosmos. What trip me for that system is the idle power consumption/the efficiency.

durodee:
That should be @Mantims

Pls house how do I stop my inverter from charging my batteries using NEPA light, my NEPA bill is 10k monthly due to the regular charging of batteries by the inverter.
Thanks

Hmmmm. See nepa light wey people dey find to tek charge their battery.
ATS is advertised up there. Install it and be changing your battery charging automatically from nepa light to pv.
