So, my questions are:
1. What's the best MPPT Controller out there?
2. When I put the third 150w up on the roof, how do I gather up all the solar output wires from the panels and get them into the controller? Thinking most of the Controllers have one or two input ports for the panels.
3. Are most cables from the panels large enough? Seems to me these are 10ga. from my Samlex panels?
4. Are all panel cables interchangeable? Are there aftermarket cables that are 8ga? Would that be necessary if it were possible?
5. When I move the controller down closer to the battery, the cables that come from the panel to the controller will now be longer. How much will that affect the charging with longer cables from the panels to the controller?
1. Morningstar, Tristar model.
2. Needs to be combined into the wiring setup prior to going to the controller.
3. Mine are 6 ga from combiner box to controller and 10 ga from panels to combiner box.
4. I got nothing for you on this one.
5. You need the controller as close to the batteries as possible so that should be your priority. the length from the panels or combiner box is secondary.
