How can I cut off AC-Out 2 in an AC-PV Coupled System based on Battery SOC?

  • From one of the recent vidoes on the Victron Professional trainings, "Coupled AC PV Inverter Introduction", @ Guy Stewart talked about the Optimal AC PV off-grid configuration and that would fix a challenge I have at an off-grid site that has AC-PV Configuration but no DC. Please how will I configure AC-Out 2 to cut off when the battery SOC goes lower than a particular threshold. Will I use virtual switch?
  • The system is actually working fine, it's just that once in a while when the batteries gets drained, and the Quattro shuts down, the Fronius Inverter can not come up until the generator is put on. Adding a charge controller and solar panels will fix this but the client isn't ready for such expenses yet.
  • On that site I have installed:
  • 5kVA Quattro
  • 5kW Fronius Primo
  • 5000Wp of solar panels
  • 13.8kWh BYD
  • CcGX
  • I'll appreciate any help I can get from @Guy Stewart or anyone who knows how to do this. Thanks
