This client’s RV was pre-wired by the manufacturer with 6-gauge cables, and an inverter. We installed 960 watts of solar power, which is more than we would recommend for 6-gauge cable, so we had to take additional steps in order to make the system as efficient as possible. With these under-sized cables, voltage would have been lost between the solar panels and the charge controller. We installed the solar panels using series/parallel connections to increase the voltage, reducing the amount of voltage drop to less than 1%, which resulted in increased system performance. This client will be able to run their residential refrigerator without using a generator or shore power.
