    Hello James Turpin，

    That is for remotel control. You can just replace the original potentiometer with it.

    Hello Scott,

    Please connect 20v directly instead of 48v battery. Any adjustable power supply is available, as long as it can offer accurate 20v voltage.  This  is for calibrating voltage reading error . If there is no large error, it is not necessary to do that.

    And you just need to program menu 1 or menu 3. They both are for battery specification setting. Meter only save one of settings.

    Best regards.

    Hello Mike Lesiecki,

    Did you hook up current sensor correctly？ Charging current is with minus sign.  If it is positive current, that means the  current flow through  sensor is reverse. Please reverse the sensor.

    Best regards.

    in reply to: battery operated timer for solar pump control #64834

    Hello

    You need to connect DC5-60V power supply or USB power supply for relay operation. The internal battery only work for clock. In general, it can last a long time .

    Best regards,
