Hi there!
I was wondering whether it would be possible to configure a multi-phase Quattro system to only utilize the external grid as a battery charging mechanism and not to synchronize against its voltage waveform. In other words allow the Victron system to generate its own VAC reference as if the grid wasn't there in the first place, but still allow DC rectification to charge the batteries.
The reason I'm asking is due to our system running in a fairly rural environment and the quality of the grid supply being poor (both over and under voltage as well as frequency quality). We seem to be suffering equipment damage due to this.
While I assume we could tighten the loss of main high and low limits, we would still prefer running isolated.
For reference, the system comprises of:
- Gateway - Color Control GX
- VE.Bus - 3x Quattro 48/15000/200-2x100
- Battery monitor - Generic Can-bus BMS battery (Freedomwon 40/28)
- Solar charger - SmartSolar Charger MPPT 250/100 rev2
