Gen Down Time: This indicates the delay-time of the generator to shut down after it
has reached the running time
Grid Charge: It indicates that the grid will charge the battery.
Grid Signal: Indicates when the grid should no longer charge the battery.

Using a generator with a Sunsynk inverter:
A generator can either be connected to the Grid side or to the Gen connection. When
connected to the Grid Input, the inverter will consider the power coming from the
generator as ‘Grid Supply’. Users should make sure this power goes to the LOAD only
and should not be exported to other outlets as this will damage the generator.
An advantage from connecting the generator to the Grid Input is that it can be
paralleled whereas the GEN/AUX input cannot be paralleled. That means the inverter
will extract what power it requires from ‘Grid Supply’ to charge its batteries.
If the generator is connected to the inverter and a generating signal exists, the inverter
will switch 100% of the load to the generator and then slowly increase the charging
currents to the batteries. Therefore, the generator must be able to supply both the
charge current and the total load current.
The generator can be controlled via a relay which has a set of dry-contacts to enable
remote control. The current on thee contacts is limited to approximately, 1Amp 12V.
Below is a simple reference circuit of an auto start system that can autostart generators
on a boat. (Sunsynk will be releasing a new OS E406 ( Auto-Start ) for better generator
control)
