I have recently had the same MUST 3kw inverter installed. I get the impression the installer (qualified registered electrician) is still on a learning curve, but I am starting from zero and trying to get the menu settings right. Twice the battery has overloaded (error 3) and once has been completely flat -0%. Surely this is damaging the battery. How to I set it not to go above or below a certain capacity? My inverter is only connected to certain circuits on the DB board (all the lights) and a few specially installed electric sockets, supposed to keep the fridge and house alarm going every day during load shedding, plus one or two small loads eg TV. The solar panels have been very successfully charging the battery every sunny day, but at night, between load shedding, the grid doesn’t kick in to recharge the battery. There must be some incorrect setting on the inverter menu. Please help this not -electrically-knowledgeable senior lady.
