All lux units can work with generator.

• Users can connect the generator output to ECO Hybrid inverters. GEN input terminal.
• The generator will be automatically started when battery voltage is lower than the cut-off value or there is charge request from BMS. When voltage is higher than AC charge setting value, it will stop the generator
• Battery will get charged when the generator is turned on, and the generator is bypassed to AC output to take all loads.

• The system will use AC first if there is both utility input and generator input.
  The capacity of the generator is recommendedNumber of the single parallel inverter| Capacity
  ---|---
  Single inverter| >10KW
  2 parallel| >15KW

It is supported to parallel 2~3 PCS inverter with single phase in single phase parallel system and three phase parallel system to charge battery with Generator! And it is depends on the load performance of the generator too.
2.7 Dry Contact Signal control
The Dry port(NO2,COM2) could be used to deliver signal to external device when battery voltage reaches warning level. The GEN port(NO1,COM1,) could be used to wake-up the Generator and then the generator can charge the battery.
