Good day all. I have a specific requirement for which Victron might have the solution but maybe i have no cross-figured it yet.
Component of installation:
- 1x Quattro 48/10000
- 2x Smartsolar 150/60
- 7x Pylontech US3000 (total: 24.8kWh)
- 1 Cerbo GX
The grid is awfull in terms of voltage (180v to 230V max). Allowing grid in daytime is not comfortable since the Quattro does not double conversion.
During daytime, we reach a maximum of 210V.
Between 00:00 and 05:00am, we can have about 220V-230V. Charging in this time period is the best and is wanted.
When the day is sunny, no issue at all. Batteries are charged around 95% for the night.
When sun is not good, we lose about 10-15% daily. Grid input becomes necessary at a certain SOC.
I use VS to allow the grid to enter when my SOC is below 25% (security). That is accetable at any time to avoid power shortage.
But now, i would like to tell the system that IF SOC<50% AND 00:00<actualtime<05:00, then go ahead to charge batteries from AC source until we reach a certain battery voltage.
IF AND ONLY IF time is between 00:00 and 05:00am.
I know that ESS has the schedule option.
Also, small energy backfeed to grid is not an issue here.
But i was told that due to Loss Of Main option, ESS won't work with unstable grid voltage and frequency. So i am stuck with a simple Virtual Switch without schedule.
Anyone can give a hint/help/indication on how to tackle the issue.
Thanks and best regards.
