I'm looking at setting up EV charging from surplus solar. I can use aux from midnite classics or relays off the Batrium. Both can be set up to start/stop around float state, float voltages or SoC states. So I was looking at a level 2 charger and was thinking of using this or similar SSR:
But I was wondering if I need to go with a larger amperage rating and whether I should find a contactor rather than an SSR?
Anybody have experience setting something like this up? What I'm thinking is essentially the lithium iron battery will charge, hit absorb andbalance, then charge controllers will drop to float. At that point, start EV charge. And then terminate Ev charge at some SoC or voltage level. I expect this will toggle on/off in some situations, but maybe not so bad if the start voltage/SoC and kill voltage/Soc are wide apart.
thx!
