On March 27th I visited "Casa Pueblo" in Adjuntas, Puerto Rico. Adjuntas is situated about a 2-hour drive Southwest of San Juan. Casa Pueblo is a community center that is currently running on solar power and independently from the electric grid.
Casa Pueblo has three controllers, a power distribution panel and two inverters (from left to right). The box at the bottom is where the batteries are located to store energy.
Casa Pueblo has a radio station at a separate house behind it. The radio station has their own inverter and battery storage as seen below.
