I do have a three phase system with 3 multi plus 2 48v 5000. I would like to use it in island mode and use the grid as a battery backup. Can you please help me with the programming steps.
The system is working fine with the battery, but as soon as I swich the grid to ac in the inverter swiches over to the grid. With SOC well above 40%.
Hopefully there is a way to realize this
