An advantage from connecting the generator to the Grid Input is 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)
