  • configure Morningstar mppt 45 controller - 24 volt panels to 12 volt battery bank

    I have 2 Grape Solar 12 volt panels wired in series to a Morningstar mppt controller. I have a 12 volt battery bank. How do I configure the controller?

    What is the Voc spec for the Controller you have ? Morningstar has many MPPT controllers varying from 50-600V input limit

          Easy wire the panels in series. Just be sure to connect the battery to the controller first before panels as that will set the controller for 12 volts.

            The ts mppt45 controller has an auto system voltage setting, OR, manual voltage settings(see page 20). You really need to set up the controller correctly before connecting it. There are a number of settings for various charging voltage setpoints, battery types, etc. Here's the manual,

              Why would anyone read the manual or directions? That would just confuse them.

                You're assuming they know how to read.

                  As a last resort.

                    Yea, that's like admitting defeat. Sort of like asking for directions from a stranger when you're lost. How humiliating.

                    An alternate: have a women read the manual and spoon feed the answer to the problem - they seem to do better at such tasks than most men. SWMBO helps me like that all the time.

                      GPS has largely eliminated the, lost and need directions problem, as long as you know how to operate your GPS. I have a few myself. Magellan seems pretty straightforward. I have a Tom Tom for Baja. It is not as user friendly.
