my dad called me that his sytem shut off seplos reporting half of the cells verry low voltage! and flactuating verry fast! the it have 3 rack over it ..so i wasnt able to open it and check .. can you please help me? can my batteriesa be affected or itys 100% a bms problem?

i have to LF280 eve racks 16 cells each .. have seplos bms each now seplos cell 280A rack for 2200USd but have gafang batteries is it ok to connect them in parallel ?

no VFD need 700V arrays

Am talking here arrounf 9 arrays each array is 15 panels Main use for water pump .. ( so i cannot change the way they are connected as vfd need 700v) Anyway i can convert the 700v to 400? And there is an hybrid inverter that take 700v panels?

i have a 700V solar array(60kw) using it for VFD water pump anyway to lower the voltage without removing panels so i can hook it with a normal hybrid inverter while still using the vfd pump ?

The ring was off.. amy is telling me it maybe the coolant used with welding What do you think guys?

it came out after i put them horizontally on the floor

unused lf280k unswollen (AMY) release fluid with an odor like acetone.. are they safe to use?
