6.6-74 Workhorse Submersible Solar Pump

The Workhorse 6.6-74 submersible AC pump package is coupled with a powerful VFD based solar pump inverter, giving the benefits of solar, as well as mains and generator capabilities. This means that the pump can run all day from solar and automatically switch to mains or generator power at night, with the added ability to blend the solar with AC power when there is insufficient sunlight.

Always refer to the maximum head and flow as per the flow chart
