12.15Kw 3-Phase 50Hz PV System with Maximizers. This large house in Barbados had more hips than the Rockettes. So we had to place the solar panels in all different directions. We coudn't use micro inverters, because Barbados power is an unusual 115/230V split phase 50 Hz or 230/400V 3-phase 50 Hz. So we used Tigo Maximizers on the DC side and they did a magnificent job of balancing the arrays. Solar Energy Innovations, our Energy Partners in Barbados,  did a wonderful job balancing  and optimizing this 3-phase, 3 inverters, 50Hz, grid-tied, net metering system.
