"How can I continue to use the AC Coupled Fronius Primo/Symo to generate solar power when the selected Quattro input is not configured as a grid but is configured as generator, or do I have to accept that it switches off which seems to fly in the face of the Fronius microgrid strategy and documentation about being able to use a fronius OFF-GRID with a generator
>>> Without a solution I will have to remove solar panels from the Fronius and put them on a Victron MPPT which means more Victron MPPT or bigger generators in every configuration we install <<<
This applies to both the ESS Assistant (Main Utility Power Connected zero feed in) and the PV Inverter Assistant (no Utility Power - Off Grid), when the generator is started during the day to charge the battery the fronius switches off
The generator is required to charge the batteries, hence the loss of Fronius power is a problem, hence how do you set the Victron (float voltage / frequency shifting parameters) and Fronius to prevent the rejection of the Generator as an input source for the fronius . . .
Everything works well when Generator is off, on an ESS works fine with Grid until the generator is started and when used in an Off-Grid configuration all works until the generator is started, in both cases the Fronius switches off, the off grid is an high quality 3-phase 30kVA generator
