Solar Panel Update
Posted: July 17th, 2021, 5:17 pm
As many of you know I installed a 400 Watt solar panel system on the Holodeck. I made 2 sets of panels in. Series to join in Pharrell, so if 1 set failed, the other would function. Anyway, we gave it a whirl My house bank is 2 6V GC batteries wired in series to make. 12. We took off yesterday afternoon for a mooring to see what it could do. During the moon lit night, the controller was kicking 1 - 1.5 amps. In the AM, the batteries were down to 80%. Before solar we were at 70%. Running were lights, water pump, 12V fans, original refrigerator on 12V and cell phone chargers. By 11:30 this AM the batteries were back up to 100%! It was a partly cloudy day, so not optimum conditions. At the peak the controller was pumping put 26 Amps. Then as we neared closer to 100% it cut back to less. I was leary to try to see if as claimed the controller would shut off when another source was present, but when I started the engines, the controller cut right back to 0 amps. . We are looking forward to trying these ion a sunny day and a week trip. My verdict: IF you have the real estate (Flat Hard top) install some panels. MPPT controller, 4 100 watt panels.
