Automatic Generator Start
For AC Generators supporting the automatic on/off function, connect the generator to the inverter
charger. If the battery voltage reaches or falls below the Low Voltage Reconnect value (when a Battery
Voltage Sensor are involved), the inverter charger will send a 5-minute start signal to the generator.
Upon receiving the signal, the generator will automatically start and provide power to the battery and
loads.
Read the user manual of the AC Input source carefully before connection.
Make sure the generator can automatically start or stop. Identify NC (normally closed contact), NO
(normally open contact), and C (common static contact) of the generator and ensure signal lines
are connected properly. Some generators only have NC and C (common static contact) or NO and
C. You can connect them on demand.
Do not install the inverter charger near any generator supporting automatic generator on/off
because these generators exhaust dangerous fumes in operation.
