C&I battery storage: all you need to know

Talk to Australians about stationary energy storage and they’ll tell you about the Hornsdale Power Reserve, for a long time the largest lithium-ion battery system in the world. Talk to Germans and they will point to the residential battery that is helping their household to run off solar power.
