Low Frequency Off-grid Inverter
SIF-1~12.5KW
SIF-1~12.5KW
The SIF series is mainly composed of stable and durable components and hardware.
It is especially suitable for complex power environments with high current impact,
and single-phase power environments equipped with water pumps, crushers, presses,
stamping machines, pumping machines, compressors, hydraulic presses, electric clothes
trucks, etc.
