I use
multiplus II.
DESS. Setting “keep battery charged” is ON.
Solar connected to MP ups side.
What i see:
PV is dumping to the grid (via MP)
At a certain moment MP starts to add power to the pv power increasing the amount being dumped to the grid. Then it stops doing this and starts to charge the battery.
This goes on and on with ever increasing power until the MP disconnects from the grid with a “ALERT - Alarm on ‘MyHome’, parameter ‘Active input’ on ‘VE.Bus System [276]’” error.
Then after a minute it reconnects.
This happens 2 or 3 times a day.
I seems to only happen during the day when there is plenty of sunshine. Until now never at night. Should i increase the amount of PV in the ESS settings maybe? They are now set to the exact amount of PV i have.
What could this be, does anyone know?
Update:
Connected PV directly to grid. So not thru the MP. Same thing happens. I must also add that my voltage on the grid is very high: up to 262 volt sometimes. MP is set to refuse grid at 266.8 volt.
Error in MP says “overvoltage.” But it is still 4 volt under 266 when it disconnects…
