Hello, This features would would be nice to have In Power station.
if the battery is full but solar power is coming in excess energy should be going to conected Loads first
if the battery is full and no load connected but solar power is coming in excess energy should go to Grid.
if 2 (or more) power stations are connected (ac out to ac in) the available output power should be combined 2* 600W =1200W total for example.
The power station should be Abdel to pull power from its output.
If a grid tied micro inverter (plug in PV) is to the output the power station should be able to charge from it.
Since the inverter of for example EB3A is running in grid Synchronous mode for charging anyways all this would be Possible by firmware update.
