Kelmma:

I understand bro
This is part of DIY and to a large extent I trust the judgment of guys here

If you guys that have used it they will let u know. My own path in DIY.

stuffs2002:


Thanks for your reply. I have already bought the s for a while because I decided to be buying the materials for my renewable energy bit by bit and I may not be able to return them now.

Pls I would like to know the following:
1) What other danger I am facing aside from losing money.
2) What are the likely parameters of the 4 s and how can I salvage the situation and I still make use of the s
3) Should I buy additional s to make up for the lose of energy as I had already calculated the output of the s to match the load they will carry.

Use them just like every normal solar

Ok.. Thanks

I want to connect all 4 s in series. Please can you suggest any good MPPT charge controller that will be able to handle the resulting voltage.

Unless u use hybrid inverter wey fit accommodate the 240v voc. Other controller that can accommodate such are as expensive as the hybrid inverter itself. Eg 140a powmr CC can take 60-450v. N it's for 24/48v system.
Is ur system 24/48v?

My system is 24V because I have two 12V batteries

I am currently using an MPPT charge controller that I got online with maximum input PV at 230Voc in my other house and I have been using it for over 2 years without issues.

I am considering getting same charge controller for this second installation but I am not sure it will accommodate the voltage of 240Voc since I am considering installing all the 4 s in series.

Can your 24v 3.5kwh parallel with 24v cworth 2.5kwh battery?

yes. so far it is 24v lifepo4... made with JK 100a 1A active balancer bluetooth BMS and JK 3.2" lcd display 750k 699k limited stock..

I have a neighbour who is interested in solar because he saw how reliable my own system is, problem is that he has a lean budget (1.1m). @valto and other gurus in the house, can his budget setup a reliable 12v system with a lifepo4 battery+hybrid inverter+reasonably sized solar s?

What would you recommend? My setup is a 24v system, and he can't afford that. Thank you

Got 12 100 yesterday for 177k.. And if am to buy 3 it goes for 170k.. They always like to cheat.. I mean the 9ja guys there.. They will never ever open their mouth to tell you the price.. I enter and told them i want to buy battery and their 1st question was from where.. Asin cant a random person just enter and buy battery.. They just want to be sure if i know the current price... Told them where i came from and the next thin was to drop me acct to make payment.. They didnt even say more then 3 words.. They were very very disapponted..

His name is Armstrong. Tell him you were referred from their sales rep from China.

See their latest quotes.

If you're buying upto 5 pieces the price reduces slightly.

Fear catch me when i was reading is write up until i come see the data sheet.. Even 500w self no reach 60v..

omotoda:


The s are fake.What is the name of the ? No way a 250 watts will have VoC of 60v.Not possible

Wow..

This awesome then.. 👍

JUO:
lol there are some with even higher voltage

In my own opinion, I suggest we stick to what works for us as individual. We can never roll out the aspect of trust in business and other indices. Mr A might sell grade B cell at 50k while Mr B might cell the same quality of cell at 80k. Someone might prefer to still buy from Mr B at a higher price because of trust and customer services.
With my limited time, I will still advice that whoever wants to buy grade A cell should first of all collect the manufacturer test report and forward it to Ev Company for verification before making payment. The Company email address is everywhere and the response is given within 48 hrs.

You used the format right format.

It should
555w * 3 = 375k
12v 2kva 230-260k (cworth/SMS)
12V 100AH LFP * 2 from cworth (less than 400k)
Or 12v 3.5kwh LFP 450k (if he doesn't mind wooden box)
PV cables, 2.5mm corper cables , breakers (if he isn't buying the brands) will cost him about 120 - 140k

Thank you so much for this insight, really appreciate it. Sorry to bother you further, Is the Cworth batteries coupled with bms already? I would prefer a coupled lifepo4 ready to use battery for him as he's not a DIY person.

@ Valto and all
I have a question that need explanation please

CAN A 10kwh Lithium battery power 1hp LG inverter AC set at 16degree temperature ( not GEN mode) 50watt fan and 100w bulb overnight ( 6pm till 6am next day) with charging?

I just need DIRECT ANSWER and forget about inverter size , size and charge controller size

Thank you

Wow...and he was telling me 590k...I bought my first battery directly from him, messaged him yesterday for another and he said 590k when the price is 555,000...

I noticed my first purchase he didn't send receipt with the order and when I found out and insisted, he said it's an electronic invoice which took him 2 days to generate... As at last year he sold it to me for 620k...

No, 1hp is approximately 750watt plus additional 150watt, making a total of 900watt multiply by 12hours, making 10800watthour. So ur best bet is a 15kwh battery, at full charge, it will suit ur need

Thank you

800w inverter Ac consumption ,plus another 150w load ,plus inverter working consumption.

approximately 1000w for 12hrs. u need a fully charged 15kwh to 17kwh battery for overnight use!

How much will 10kwh lithium battery cost me ( kindly give me different grade to choose from)

Thank you

I noticed the same with them.they are usually secretive with the price. Different prices here and there.they like using statement '"tell them you are from so so person"..to me it seems their marketers usually increase price from the official price...this is not really good.

@redgem, what's your experience with the Cworth 24v100ah battery ?
