EP Cube is an all-in-one energy storage solution for residential applications. After the successful launch in North America in September 2022 and Spain and Italy in the first quarter of 2023, we are now presenting EP Cube for the German market where demands for residential solar PV systems and residential battery storage solutions are growing rapidly.

EP Cube is small, 24 cm in thickness and weighs only 35 kg per battery module. Its installation is easy, quick, and safe with EP Cube 2.0 bracket. The commissioning of EP Cube is designed to be seamless using a mobile phone app, with step-by-step instructions.

EP Cube enables customers to boost the efficiency of electricity for self-consumption, by storing, managing, and utilizing the power produced by consumers' own PV system. EP Cube is a lithium iron phosphate (LFP) based residential energy storage solution with an integrated hybrid inverter and stackable storage modules. The product is both AC-and DC-coupled, with an AC round-trip efficiency of up to 95%. EP Cube offers a flexible solution with capacities ranging from 6.6 kWh to 19.9 kWh and compatibility with most current PV systems, micro-inverters, and EV chargers. Its IP65 classification makes the system resistant to water, dust and humidity, and therefore can be placed both indoors and outdoors.

EP Cube is developed and produced by Eternalplanet, a consumer-oriented independent brand of energy technology under Canadian Solar's CSI Solar subsidiary.

Further information about EP Cube will be available at Canadian Solar's booth A2.380.
