Hi I plain to build a 12v 400ah lithium bank one concern I have is that at times will be drawing a heavy load over 210a for short times ,
Am I correct in thinking the BMS will shut the batteries if it unable to deal with sure a load ? And if so what is the way around this please .
so this system that in the house we not long purchase as an Growatt which I been told is fault,
Checking the sunny boy inverter it show it putting in around 10kwh at the most per day .
I been quoted for a givenergy Gen 2 at 9.5 kWh
Or
All in one 13.5kwh
As my panels are only max at 10kwh is...
I have a Chinese 3000W-6000w inverter in reality it never going to give me any thing like 3000w, batteries bank 400Ah .
am I correct in saying a 250A fused will be fine ? 3000/12v 250A
Also where best to fit the fuse, V+ next to the battery terminal? Or by the inverter?
The inverter came with 4...

Thanks
My cells are about to turn up any day now 8x200 Calb and although I read most of the topics on balance , I like to just get things clear in my head , please bare with me first time with lithium and bench power supply .
My first question is it better to series and parallel charge as one bank...
Totally novice so please be kind with your reply
I am buying 8x 200ah Calbs cells, it seen the best way to top balance them is first wired them in parallel and give them a full charge.

We trying to top balance 8x200 ah cells with a 10A 30v power supply in stages 3.4v 3.5v 3.65v
Each cell 3.32v and then we wired them up in Parallel.
Before connecting up we set the power 3.4v turn the current down , turn off the power supply , connected the power supply to the...
It seems I may have to top balance again ( once voltages reach 14v the cells are reading 3.47v 3.50v 3.61v 3.49v )
If I charge them in parallel here a few question I like answer to please
1 Am I looking at setting the PS at 3.65v ? At the end of the PS leads 3.65v? Or at the batteries...
