Thanks a lot. I heard the LifePO4 batteries are very expensive. Can you give me the cost of getting it?

They are not that expensive.. if you check the life span.. but come with some careful practice too..

You can get 2.5KWH (12V 200AH or 24V 100AH ) for ~ 600K..
90% usable capacity..
But you must get an inverter with editable battery profile, where you can set Battery cutoff and Bulk voltage. Ranges from 400k.. for Mercury hybrid

Ok, does this inverter have the features you mentioned

Okay, thanks. How many 440w Jinko solar s will I need to charge the 12v 200ah efficiently?

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?

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.

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

RS232 is a networking port.

RS232 can be used to configure stuffs more like a console port to your PC.

Most times it is command line based not GUI

2 minimum. But you will need extra charge controller as your inbuilt controller need 4 minimum..

Just close eye and get 4.. that's about 1700w.. enough to charge use during the day.. also cater for bad weather

Goodmorning everyone and Happy Easter

Pls need advise on the type of solar and quantity I should go for

I have an inverter set up already
2 * 220mah tubular batteries
1 * 3kva inverter pure sine (24v)

I want to add solar to it and need assistance on the best solar ,the quantities and type of mppt controller required . Thank you

Good Morning Bosses,

Happy Easter and thank you all for the advice the last time.

Update on my decision and progress.

I bought a 3kw Felicity hybrid inverter and 6kw Lantan LFP battery.

I also ordered 8pcs of 625watts Jinko s from Fouani.

Cables: 6mm dual core.

SPD protectors (AC and DC).

My journey to full Lithium begins in a few days.

I am using large arrays for high yield as I intend to run two fridges and an inverter AC during peak hours.

Please advice on solar array configuration. Should I use 4S4P?

Please I need help on this.

I want to setup solar system for four Thermocool Freezers with these ratings on it.
VOLTAGE/FREQUENCY: 230V ~ 50Hz
WATT/RATED CURRENT: 110W/1.2A
ENERGY CONSUMPTION: 0.77Kwh/24h

I want to use Lithium Battery
Please which inverter capacity do I need.
Also which battery capacity is needed.
And how many solar s do I need.
Please help

You didn't indicate whether your inverter is an hybrid or not but pertaining to the question asked, u need 475watt x 4pieces to charge to full and additional 475watt x 2pieces incase u need to power some appliance in the afternoon

What is the VOC of d hybrid inverter? I guess it should be around 145v, if it is truly 145v, then u won't be able to do 4s4p, my advice is that u get an additional one to make 3s3p n increase ur cable to 10mm but if the inverter is a high VOC, then u should connect all in series n ur 6mm is good to go

Thanks a lot. I heard the LifePO4 batteries are very expensive. Can you give me the cost of getting it?

not that expensive, considering the actual capacity. right now it can even be slightly cheaper than lead acid
e. g
4pcs of good tubular batteries 370k=1,480,000
@50% DOD is around 5200kwh
my 24v 280ah 7168kwh LIFEPO4 LITHIUM is 1.380m @ 90% DOD =6,452kwh
also 3 or 4yrs lifespan with plenty maintenance
vs zero maintenance and over 12yrs lifespan

the choice is yours!

Since you plan using lithium battery, buy hybrid inverter 3.5kva 24v.

That's what is readily available in the market.
@valto get for sale.
You didn't include the time you want to run it.
So I can't provide any opinion on it

What is the mppt input voltage range of your inverter? Is it up to 400VDC? If yes, series all

U will also need a 60amps MPPT charge controller with d s quoted above and a 10mm DC cable... if u are not a DIY enthusiast, buzz me, lemme handle ur installation for you

Thank you so much Edrizz. I am a DIY enthusiast and I wouldn't have thought it twice to engage you but the problem is distance. I am in Kaduna.

I appreciate you

Thank you so much Val. I appreciate

Sir, are you saying.thos is the price of 105ah LifePO4 battery? 280k? Truthfully?

dollarnaira:


Pls tell me one person with one tubular on freezer? We are all here to learn.

Start up of the freezer is roughly 700w to 900w oooo.

That it the annoying part 50% DOD
ROUGHLY dat is 110k for 330k. 105ah LifePO4 is 280k with 12yrs or more. Most of are being deceived by 220ah that is already fake.

Max Solar Voltage (VOC) 400VDC

If it's Jinko 625w sold by Fouani, the VOC is 56 .55V, then I won't advise you connect all 8 s in series as the total voltage will be (452.4v) which is more than max VOC of inverter 400v.

Max s you can connect is 7 s, or 6 s to be on safe side.

But is the Voc of <50v, you can connect all 8 s in series.

You also need to get AC & DC MCB + Over Voltage Protector, @Zeestone99 sell both devices!

OMG! TechGeek you just saved a life.

I checked the VOC of the . Damn! That would have been brutal.

I ordered Chint MCB's as against the fake Schneider that was once supplied to me by a vendor here.

Thank you so much Sir. God bless you

Oh, you're right brother. I just checked n saw that it's truly within d range of 55.17 and 55.72


His best bet is 4s2p then provided that d amperage of controller is 40amps n above

Please do endeavour to check d amperage of the inverter, some inverters come with high VOC, low amperage... sorry for the error initially committed
