Re: morningstar ts-mppt-45

Take a volt meter and measure the voltage and polarity at the battery bank connection. And, if the sun is up, measure the voltage and polarity at the solar panel input connections (do both measurements on the meter connection points to make sure the controller is actually getting the proper voltages).

If you have any digital connections to a computer--Disconnect those for now.

Disconnect (or turn off) the solar array. Then disconnect the battery bank (just one lead). Wait a minute and reconnect the battery bank first. Then reconnect the solar array second. Many charge controllers will not start correctly if the solar array is connected first and the battery connected second.
