A tenant can actually do something like this. Infact, me personally, I don't like panels on the roof.

mctfopt:
Where did you install your panels?

Thanks for your response sir,

The 5units are lithium. They were to go into the same system but one of it had a defect, the cells inside shifted on their mounting and was shorted to the casing of the batteries.(the dealer acknowledged it was a manufacturing defect for this type of their batteries)
The batteries are rated 9.6kwh on the nameplate -the dealer says it is 10kwh- it is mated to a 18kw inverter and 13.2kw of solar with remote monitoring.

The batteries were bought February this year. And we're integrated in installation by July this year.


All other aspects of the system are working pretty good, just the battery.

isangjohnson:
I'll do that now Sir.
Thanks

A single testimony from a satisfied and verified customer, is worth more than a million advert.

Sellers using proxy accounts to promote they brand, you are only doing more harm than good to your brand!

isangjohnson:
Selina representing Shenzhen New Deriy does NOT sell grade A cells. If you doubt, then let her give you the manufacture test report from Eve and let's look at it and confirm.
I don't know about others

Justice629:
@bassdow
I gbadu your inputs here well well but as I no be keyboard warrior I say make I maintain for corner the look many of them do called solar pros here.
Little piece of advice- when you ready to go lithium no make mistake of buying from naija vendors because must times na worst grade cells them dey buy from China, my own experience still the pepper me for body now.

Obnoxious2001:
Inverter can take upto 450v dc

Obnoxious2001:
Attention please I need your opinion.

In a recent installation I embarked on, I was having thoughts on Which configuration is best for a hybrid inverter system.
(3kva 24v)

Voc of the panel is 64v, 7amps
No. Of solar panels is 6pcs of 380w panels all connected in series (output voltage is 360+) charging a 24v 100ah lithium battery

Vs

2s3p (output voltage is 120+) charging same 24v 100ah lithium battery.

This system has a continuous load of almost 700w in total.

Which panel configuration is best

FEGEITOK:
Post-mortem of the plug
@TechGeek777 and Valto thanks

FEGEITOK:
Hello house,

I tracked down a wire burning smell to the electrical plug adaptor that my inverter is charged by the mains.

I then touched it, and it was hot so hot it could burn if the fingers were left there for a considerable length of time.

What is the best way to resolve this issue?

gadgetplanetng:
Same here I stopped using the CC.
I notices if the battery is low, it charges normally but once it's full it starts going over.
I actually planned to get another cc to test but this confirms it.
What type of Lithium battery do you have?

dejidotun2000:
I get what you mean about the calibration but that isn't what is at play here. The CC maintains the set 27.6V for some time but "losses" the setting later and begins to output over 30V. It wasn't like that initially and when I noticed it, I also thought it might be due to voltage drop along the battery cable but after several checks and attempts to calibrate what I realised was that the CC was actually "forgetting" the set voltage. Feat didn't allow me to use the CC since then.

Penuelseun:
The guy knows almost nothing about lithium chemistry, just copy and paste from Google. Who still uses li-ion for diy these days. People that have never coupled or installed an inverter or electrical system before will just come here and be forming overnight guru

bassdow:
Current is NEVER TOO MUCH because the applicance draws what it needs.
It's Voltage that CAN BE TOO MUCH because it flows into the connected device.


in other words, if a phone's charger is rated 5-volts 2A , you would have no issue connecting it to a charger rated 5-volts 400A. BUT no make mistake connect am to charger of much higher Voltage.
