then the generator may slow down when switching in. This causes a frequency shift that will shut the
inverter down, which can be very inconvenient as it will happen repeatedly.
In order to help the generator on a sudden surge current, the Sunsynk inverter steps up the charge current
to the battery. At this point it will be providing the full load on switchover.
If your generator is not powerful enough to supply the full load and handle surges, you could choose to
use a separate battery charger, charging the batteries directly. We often recommend using a second inverter
or a standalone inverter in battery charge mode. This inverter will be connected in parallel on the battery bus
bar only to charge the battery when required or assist the battery charging. It is not connected in parallel with
other inverters; this inverter is only connected to the battery. But, the MPPT of this inverter can still be used
for charging.

The generator relay on the inverter can
automatically start a generator. However,
the generator must have a suitable A/T/S.
