50% dept of discharge is not at 12v , onye ara

peterpeteru:
Hello Gurus. Kudos for your great work here.

My 3.5KVA Ipower inverter is displaying a code 6 error. I took it to Zinox office and was told to pay N85k for repairs which will take 4 weeks. This is the 2nd time of repairing it there. The first time it took them 9 months. A week after collecting it, one of the fans stopped working, but it still worked and I supported it with an external fan.

I don't even load the Inverter up to 10% since I bought it 2 years ago, yet it keeps having issues.

Please, what do you advise? Any alternative step I can take? N85k is too much for this unreliable device biko.

For that distance voltage drop is more than 5% using 2.5mm2.

I use Astral 1.5hp, 2.5mm comester, with depth of 177.5ft and Amps draw fluctuate between 8-11amps.

Which inverter do you use?

Happy Sunday guys.
Thanks for your valuable responses to this 👆🏾

You all have advised me to get a transformer based inverter as replacement.

On a second thought, I'm thinking of upgrading my setup too.

My current setup:
1. Ipower 3kva hybrid inverter (now damaged) but I'm presently using my backup 2kva ipower Hybrid inverter.
2. 60A ipower MPPT CC with solar max voltage of 145 Vdc
3. 2 GSR G250 tubular batteries (maybe 200ah or 250ah, I'm not sure). But it's a 24v setup
4. 4 300W mono solar panels

I have a slight issue though. Due to the position of my house and the roof design, I observed that the sun is usually on the opposite side of the panels any time after 1 pm. So, the charging rate is usually low during this period.

1. How do I resolve this issue?
2. Please recommend a medium level upgrade to this current setup. I'll appreciate if it can power my 1hp Home water pump, not necessary though (I don't know the power rating).
3. Recommending tested and trusted brands is also highly appreciated.
4. Additional information or advice

Please note, I'm completely off grid.

Thanks and God bless!

1.356kwh......Isn't this on the high side?. Mine consumes less than 0.85kwh in 24hrs

Happy sunday everyone. Out of curiosity, i got a multimeter... i have 4 batteries connected in series..after testing all came out 12.2v except one which came out 11.8v. Note that they re not fully charged as i have used them b4 testing... my question is, are they not suppose to discharge on thesame level??.. as same 12.2v for all??

Deye 5KW

kristien4:
the 11.8v is coming from the battery at the positive end of the series..

Anyone with experience using poly panels for installations.. what are the cons and pros of using dem as regard to mono... I heard de are less efficient than their mono counterparts

As expected..
This is a normal behavior when your batteries have degraded.

Swap the battery and you will notice the same thing with the other batteries as well. The positive end will read 11.8V.

You batteries have degraded.. start saving for new one. Or go Lithium for peace of mind.

kristien4:
batteries are 2 weeks old... is it possible that exact battery was actually low wen it was connected in series, hence did not attain the level of charge the others had?

Dam5reey:


For a new battery then, you need to equalize them, charge all in parallel, with a 12V charger until it's Full Full.

that means i will charging 800ah battery with my 12v 20ah charger...that na till weekend ooh..😎😎😔😔..

Big boys inverter

Wasn't as pricey as it is today when we bought them.

Mostly is advisable to use battery equaliser for a 48volt system cos of stuff like this, normally what I do on site when I want to install 4 battery is that I will parallel all battery with a DC cable first thing first, then continue with other activity, I do that to balance the battery voltage to prevent issue like this. Once the battery with 11.8 reaches 11volt, then ur inverter will start buzzing. To solve the disparity in voltage, disconnect d 4battery from the inverter n charge controller, place them on a spacious place, get a 16mm DC cable n connect all Positive terminal together n do same for Negative terminals too... but u have to be extra ordinarily careful when doing it cos d positive cable mustn't come in contact with the negative cable or better still, get an engineer to help u with it. I base in Ibadan in case u also resident here

kristien4:
Thanks...i have the cables, i will do the parallel connection. Is this what u mean by battery equalizer?

kristien4:
And secondly, do i still need a battery equaliser after doing this "parallel balancing"
