Mostly used where blackouts are often. Is ideal for large refrigeration systems, fish farms, etc.
The battery’s capacity is calculated using the maximum possible blackout duration and the maximum power needed by the consumer devices. The system is grid-tied and when the batteries are fully charged the excess of electricity is passed to the grid using Net Metering system. Application: hybrid solar stations are ideal for refrigeration stations, fish farms and other activities highly sensitive to even short lasting blackouts. Pros: very high level of comfort thanks to batteries Cons: needs more investments than a grid-tied system
