Hi from Greece, we have installed a 3phase ESS System with 3xMP 48/5000 and 4 MPPT 250/100. Due to different reasons we are 80% Off Grid. Additionall we have a MyPV Thor9. The Thor works perfectly with the ESS, but not OffGrid. Any ideas? The victron guide asks for a pv assistant and a physical installed inverter on ac out. At the moment, no inverter at ac out. Any workaround? Thanks for any ideas
