Hi, I have a Multiplus II 3000 24V with a 7kWh LiFePO4 battery in a campervan that's connected to my houses mains supply.
I have ESS installed and using the scheduled charging setting on the Cerbo as I have a very low electricity rate in the night. This works great!
I've tried setting the Grid Setpoint to -250W to offset the base load of the house during the day when electricity costs are high but it seems the most I can feed back in is around 80W. It doesn't matter how low the Grid Setpoint value is set, it never feeds in more power.
Am I missing something here?
