hi
i have two multiplus 3000/24v in parallel master slave mode. we live off grid with a 1000ah c5 battery bank, a large industrial clean supply generator.
ok so the problem, when we first set up all worked well, now when on generator only one inverter switches to pass through mode, but you can hear it intermitantly switching a large relay/contactor, the vrm shows bizzare data, wont supply more than 3kw and if house load goes above this the batteries are used, all the time the "faulty" inverter clicks and clicks.
so i assume the sensing of mains on this second inverter is faulty, my issue is we have already sent the device away once under warranty and they sent it back saying it had no faults, the cost to post we had to pay, we got it back and still was the same, our biggest issue is relying on the power so sending it away again in winter we are not happy with.
i am an electronics engineer, and would happily replace the board myself, can i buy a PCB? if this is fault?
