- email us here for: "where's my stuff", product, system and shipping quotes, availability, and solar product questions.Testing charge controllers: Nearly all charge controller REQUIRE that they be hooked up to a battery in order to operate. You cannot hook up a solar panel to the input and use the LOAD or OUTPUT with no battery connected. Also, if you try to measure the volts or amps on those terminals with no battery, you will not get a valid reading.
