These full-service renewable energy systems give you all the benefits of utility interconnection and net metering plus energy independence. With these grid-tie systems, backup AC power is made available in the event of a utility outage, providing reliable power and peace of mind. An average conversion efficiency of 89% to 91% using the California Energy Commission (CEC) test protocol provides greater savings and a shorter time period for system payback than previous designs.
Battery-backup grid-tie systems come with modules, array wiring, combiner boxes, roof mounting structures, inverters/control systems with all required over-current protection and disconnects. (Your specific installation or utility may require additional AC disconnects, which we can supply as needed). They require a 48-volt battery bank to operate. The size of the battery determines the amount of backup power available during power failure. Use the worksheet on the page 11 of our printed catalog to determine battery bank size. Battery backup systems qualify for the California Energy Commission incentives and the federal tax credit.
