Bill Oliver from USA is building a hybrid solar power system using the POW-M100-PRO charge controller. He recently installed two 100amp units, which are performing reliably with solid build quality and excellent packaging. Currently, the equipment is temporarily placed in a ventilated box under the panels. He plans a dedicated power room with additional inverter, 60A charger, bus bars, and expansion for 12V ham radio use. A 48V system and generator space will be added for expansion later soon.
