Hi, I am having a multi 12/1200/50-16. When I turn on with battery only, it works very well but then when I connect to grid, the relays make click sounds but won't connect fully to grid even when I checked with VEconfig 3, the input voltage was 230 and frequency was 49.9hz from my Phoenix inverter 12/500 230 because I thought it was a bad grid frequency.
After a reset to default, nothing changed the relays would click repeatedly almost after every 10s
I tried charger only, it did the same thing
It also shows that the output is on at 40vAc when it has shutdown after those clicks.
I also tried to look for the new firmware but I couldn't get the one to match.
Thanks
