![]() This works well for land based systems, not as well for boats. Your panels are wired in series and then to the controller. I don't see an obvious answer to your concern about the battery switch not depowering the panel, however, there are a couple of things I did notice.įirst the solar panels. ![]() Not sure what else might be relevant to help understand the issue I have recently mounted (2) 320 watt solar panels and I am itching to connect, but worry about the battery switch problem.īatteries are (3) 100 ah Battleborn Lithium Ion + (1) West Marine AGM starting battery My next step is to begin to troubleshoot this and see if I can isolate where the problem really is.ĭoes anyone out there know anything about this? I am very much amateur and consider all things electrical as black magic. I have replaced a couple of DC circuits as well as the AC wiring (for a galvanic isolator and the inverter), but main positive and negative are original. All of this wiring is original (1987) or at least upgraded from previous owner. I am wondering if I have a ground fault from the distribution panel. Well, the honeymoon has faded and my concern is re-emerging. I had been so excited about all my new goodies and the increased performance of the electrical system, that I called the project a success and sort of left that nagging little tidbit about the battery switch in the background. Despite the success of the install, it did not seem to resolve the issue. the system (including an inverter) was engineered by Northern Arizona Wind and Sun and they also reviewed my install diagrams to confirm. About six months ago, I redesigned and replaced the batteries and all components (bus bars, ground terminals, isolator, combiner, breakers, cables/wires, terminal ends, fuses, etc.) within the box, including the battery switch. ![]() The surveyor noted the problem and suggested it be fixed (among others), but otherwise considered the vessel "seaworthy". I bought this boat a year and a half ago and noticed this problem while performing the initial survey before purchase. ![]()
