The Chinese-Canadian manufacturer of solar systems is presenting at the RE+ trade fair in Anaheim, California CanadianSolar introduced its new hybrid home storage system. The battery, whose cathode is made of LiFePO4, has a round-trip energy efficiency of 93.93%.

“Designed to meet the diverse needs of homeowners and installers, the EP Cube is highly customizable,” the company said in a statement. Homeowners no longer have to choose what can power their installation as the whole home can now be powered by the EP Cube. As for the installers, they can efficiently set up the unit as a whole, which ultimately allows for growth and savings.”

This new product is available in four versions with a storage capacity of 9.9 to 19.9 kWh. The smaller device is equipped with a 3-battery module, the larger with a 6-battery module.

Each battery module measures 600 mm × 600 mm × 180 mm and weighs 20 kg. The weight of the integrated battery inverter varies between 130 and 220 kg and its size between 600 mm x 1,210 mm x 220 mm and 600 mm x 1,855 mm x 220 mm.

The system works with a maximum PV input voltage of 600 V and a PV input voltage range of 80 to 550 V. With four MPPT channels, the MPPT controller works between 90 and 550 V.

With a 10-year warranty, the product can work stably for 6,000 charge cycles. “The EP Cube solution can be stacked to achieve capacities from 9.9 kWh to 19.9 kWh,” said Canadian Solar. Up to six units can be wired in parallel to provide a total of 119.9 kWh of storage and 45.6 kWh of power, which is more than enough to fully power an average household with high voltage appliances and AC units.”
