Cerbo recording high input voltages.

Cerbo recording high input voltages.

Input voltage, MOST of the time, is just below the uk high limit.

When connecting an isolation transformer the input voltage increases a further 7v which triggers high voltage alarm (exceeds the uk limit 253v) at least twice a day.

A week ago, with the isolation transformer connected the input voltage exceeded 270v.

1... With the Victron Inverter upper input limit of 265v, will it shut above that voltage or will it cause damage?

2... The isolation transformer, is not a Victron product. Does the Victron isolation transformer also increase the grid voltage slightly?

Please help.

1. The MultiPlus/Quattro will disconnect the high input voltage.

2. Yes the Victron isolation transformer also increases the output voltage a little bit.
"Note: The AC input voltage is raised by 1:1.05 ratio at the AC output."

Thank you.

One last question .... the Quattro hum a great deal more when the isolation transformer is connected. Is this normal?
