Hello,
My Multiplus-II installation generated 5 grid loss alarms today, but the reason is not obvious.
I also have 2 on-grid inverters (connected to AC input) that have not detected any loss of grid and continued to produce power without any interruption.
I connected to the Multiplus with VE Configure 3 to see if there are any details regarding this grid loss alarm and observed “UMains” highlighted in Red or Yellow.
The voltage is high indeed, but it’s lower that the over voltage limit.
The multiplus remained on battery power for a few hours (3-4) until the voltage dropped a little, very cold and sunny day here and the grid had high voltage.
Anyone any idea what happened here ? , Thank you.
