First of all, big shout out to Solar supply house, I ordered the 302Ah CATL Cells Friday night 9 PM, received them today, Tuesday 1 PM. Can’t beat that! (I’m in Los Angeles)
I am using these to replace two 100 amp hour AGMs in an existing system I’ve built. I have a 3000 W inverter running some big loads that are meant to run one at a time, like a 2kw induction cooktop, 2.7kw on-demand water faucet, 700 W microwave, etc. It must be taken into consideration multiple loads will, for sure, be turned on at once creating a peak load over 3kw for a bit until the inverter shuts down.
My understanding is, and please correct me if I’m wrong, you can set a 250 amp BMS to shut down at a preset amperage let’s say 240 A, which will be an extra layer of protection for the inverter.
Question 2
3 kw at 12 V is 250 amps, is this the size BMS I should get?
Question 3
Brand Recommendations?
This is a fairly expensive build, failure/fire is not a good option. Also, this is an Overland/off-road vehicle which does hundreds of miles every year on washboard roads, it is amazing the vibration does not break more stuff then it does, but it does break stuff.
