TENTEK Tiger series microinverters are on/off grid inverters, which work with our Tribune-EMS series controller to magically create a residential solar storage system that will support battery mode operation without main power. In addition, two independent MPPT inputs ensure the maximum output of each solar panel. Since the 25-year lifespan of microinverter is designed to be the same as the solar panel, customers do not need to be worried about the hassle of replacing the inverter after a few years.
