Thought it could be nice todocument my progress on the forum.
Starting of with my 7s20p witha maximumcapacity ofabout 1kWh.
Best cells (~2500mAh)in the top left pack, crappy cells (~1500mAh)in the bottom right pack.
Waiting for a couple of meters withshrink tube from Chinato isolate thewires before I can move on to the next step.
600W 24vpure sine inverter from Mercury. "Soft start" is supposed to mean1200W for upto 2 seconds. Payed just belowEUR 100 for it with shipping to Sweden.
I have no clue how good or bad this is, but from what I could read it seems quite nice.
2A type B circuit breaker to put on the inverter output. That means 480W, even though the inverter handle short burstsup to 1200W. But I don't want to put any strain on the cells while I only have 7s20p.
The inverter has blade fuses, but I of course prefer to use acircuit breaker...
I was actually considering a 2A type C or D circuit breaker to allow short bursts up to 600W, but wasn't able to find any detailed specifications for circuit breakers that told me exactly for how long it would allow the bursts. So rather safe than sorry.
40A circuit breaker I'll be putting between the battery and the inverter. Still waiting for it from Taiwanthough...
