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 ensure
this power goes to the LOAD only and should not be exported to other outlets, as this will damage the gen-
erator.
An advantage of 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 with a set of dry-contacts to enable remote control. The current
on the contacts is limited to approximately 1Amp 12V.
Below is a simple reference circuit of an auto-start system that can auto-start generators on a boat. (Sunsynk
will be releasing a new OS E406 ( Auto-Start ) for better generator control).
Recommended battery settings:
Absorption V: The level of charge that can be applied without overheating the battery. Absorption V is
for an AGM battery is 57.60V.
Equalization V: Equalizing charge/overcharge to remove sulphate crystals that build up on the plates
over time on lead-acid batteries. Equalization V for an AGM battery is 58.80V.
NOTE:
Do not alter these settings too often on the same battery, as it may damage the battery.
