Ok, Quattro 24V with latest software update and Cerbo GX with latest software.
Boat with shore power and 2xMPPT 150/45 with 3000W solar.
Bug: when you set an alarm for grid lost, and, use virtual switch to ignore AC , you get a grid lost alarm every time the Quattro ignores AC input. The grid isn’t really “lost” if I ask the Quattro to ignore it.
I suggest that the grid lost alarm should only be triggered if the Quattro attempts to use grid, but finds no grid.
I hope I explained good enough.
