Ive inherited this inverter multiplus compact 12v 1200 va 50 amp which supplies power to my back up battery on my submersable pumps in my basement
we had a power cut and the back up didnt cut in and it was flashing red on the inverter, its now flashing orange on the charger light
can anyone tell me what i need to do to get it to charge my battery if the power goes off again im confused as to what lights should be on/flashing and do i use the charger only switch at anytime
