hello,
thanks to everyone who contributed here. i learned a lot and was able to jump in based off all the info shared
a few months ago i moved to a small urban farm part time, and put together the following solar rig:
2 x 260 watt REC panels
rich solar 40 watt mppt
4 x interstate batteries in series (6v, 210ah)
wzreb 2kw 24v puresine inverter.
the set up seems to work well for charging devices (phone, tools) and runs an apartment-sized fridge without issue. my issue is when i use the induction cooktop (1200 watts i believe), at level 3 or 4 out of the 10 settings, my battery voltage swings wildly, going from 26v+ down to 20v. if i disconnect the fridge i think it doesn’t go as low, perhaps 21/21v. as soon as i turn it off, the voltage picks back up to 26v+ and shows 100% charge. i know fully discharging lead batteries is bad, am i a bad man and doing that? or is that swing somehow acceptable?
thanks!
