    Solar controller with high/low relay option for 2 speed motor

    Hello All,
    Is there a stock solar controller that offers a 2-speed relay for high/low pump operations. When solar is called for motor switches to high, no solar, low speed.

    Doing some ground work, thinking about adding solar.

    Many of the automation systems will do that, but I haven't seen a dedicated solar controller that does. Several of the solar controllers could be easily modified, just replace the SPST relay with a SPDT relay. But that does require locating a compatible relay.

    The SolarTouch can have a dual speed relay added ... although a little more than a basic solar controller, but less than the full automation systems.
