Start Generator from Sunsynk
The off-grid installation uses parallel 50kw Inverters. We have a 150KVA generator on site I want to use and start from Inverters to charge Batteries and carry Load. I am aware that the AUX port can be paralelled but I can connect the Generator to the Grid Port which will allow the Gen to supply both Inverters.
Now my problem is that if I use the G-start to start the Generator and the AC is stable after a minute or two, the Inverter does not want to use the now present Grid Power to Charge the batteries and run loads. I expect that it is looking for power on the Aux port.
Has anyone done a similar setup? I see there is 2 additional dry contacts, does anyone know the function of these dry contact as the manual refers to them exactly once.

Use Aux port to signal Gen start
