So I had my system installed couple of weeks back.

7.2kw Kodak inverter

2 x Narada 7.2kw 150ah 

15 450w mono panels East/West as solar panels for geyser took the north facing space.

1st issue, the one battery seems fine, showing 150ah on the battery bms.

The other battery connected in parallel displays 200ah nominal and 90 Soc the battery never goes to 100

i had the installer here this morning but he tells me it’s fine, I am not so sure, should I be worried?

The one battery also shows 6 cycles whilst the other 200 shows 2 cycles.

is this fine or should I get someone else to come and check? I was never in favour of the narada batteries but got them now.

Thanks

Hello, I´m new on this forum, but are you try testing one battery bank at time?. Disconnect one of the battery bank conected in parallel, let it work for a wile and check. Then do the same with the other battery.

Good Luck!

Hi Mauricio,

Thank you for the suggestion, will give it a bash.

No such thing as a stupid question.
