proper genny wiring for dual inverter off grid
I did a 6 hr round trip drive ot troubleshoot a system; I didn't install it. I've never done an AGS with a dual inverter system so I'm not sure, but I feel like the wiring was wrong and wanted to check before I tell the homeowner their installer is liable.
It is 2 Magna 4448 inverters wired as master/slave with a decent amount of production and storage, AGS set for a Generac. The genny was wired into both of the inverters (L1,L2,N,G) and the slave inverter burned out. The installer disconnected the slave and told the owners that they simply didn't need it. Eh. I reconnected (RJ45 into the comm center for remote, batt sense) and fired up the system (no genny on) and teh slave is clearly faulting. No smell of ozone or burn just loud, creating surging in circuits, clearly busted. Is this an issue that could have been caused by improper genny wiring? My gut tells me that only the master inverter would be wired to genny charge; more info if needed.
