The OPSS can work with:

1. Diesel/gasoline generator

2. Outdoor Power Supply

3. Commercial Power Supply

Generator Requirements: 

1. Output Voltage: 95VAC~140VAC, 

2. Output Current: Max 2A.

3. Output Power: >/=500W (Otherwise, the efficiency is low).

It is recommended to connect an external power strip and then OPSS, to avoid the unstable output of the generator if any.
