December 20, 20214 yr Good Day Setting for charging 48v Lithium 120a battery is on 60A Also set on SOL Battery setting US2 (No BMS communication) Two parallel strings of 6 panels (390w each in series) This morning used belt sander, afterwards air compressor 50l (not for long, about 20 minutes) I got a funny smell from the batteries and the fuse box 160a on each terminal was quite hot as well as negative and positive going to inverter, think this is off the charging. Is this normal Thanks Deon
December 20, 20214 yr 60 Amps may be a bit to much, what does your battery manual says regarding charging current. What is the size of your battery cable? if it's 35 mm2 it will most definitely get hot as it cannot handle 60 Amps. I would personally change it to max charging current 40 Amps---- parameter 2
