SolSwitch™

 

 

Pumps, compressors, fans, and other motors may need to run when solar power is unavailable. The SolSwitch provides safe and simple manual power transfer between solar and an AC generator, or the grid, using either a single or three phase power source.

 

 

Many pumps, compressors, fans and other AC motors may need to run when solar power is unavailable. Examples include unusually cloudy weather, backup power situations, or nighttime operation. When combined with the PicoCell controller the SolSwitch provides AC backup capability by using utility grid or generator power as an alternate power source. For those critical applications where daily solar power has to be supplemented with AC power, the SolSwitch allows the customer to – both safely and simply – manually switch the power from the PicoCell (solar driven), to an AC power source (directly driven).

The SolSwitch is controlled by a robust industrial Programmable Logic Controller (PLC), which provides optional features, including external sensors, a programmable timer and more. For special applications, it is possible to configure automatic power transfer from solar to the grid/generator power with the SolSwitch.

The Solswitch comes with a standard DC disconnect built in, and can be configured with additional protections such as Ground Fault Detection (GFD) for use in open water applications, such as aquaculture or swimming pools.
