This is a head scratcher and I can use any help before tearing it out and taking it for repair. My Multiplus 2X120 stopped charging the batteries. I assumed the 300amp T-fuse had blown at some point. I replaced the fuse but nothing changed. With the help of my meter I can say confidently there is no 12V going in or coming out of the inverter. If I cut mains power the house just goes black. No inverter, no lights on the unit. I bypassed the fuse with a jumper cable an no difference.
Is there some sort of breaker inside the Multiplus? I have it n VE Config and checked every setting. I am reluctant to take it down but I may need to send it away to be repaired. Any help would be appreciated. I van even have a tech come in by the Cerbo but it doesnt show any problem.
