A hybrid solar energy system combines the components of grid-connected and off-grid solutions: solar panels, a hybrid inverter, a battery storage system and a connection to the electricity grid.During sunny hours, the panels generate direct current, which the hybrid inverter directs both to household consumption and to charging the batteries.
The priority is to use the generated solar energy first to cover the household’s current consumption in order to reduce the amount of energy purchased from the electricity grid.Surplus production can be directed to the battery storage system for later use. When the batteries are charged and production still exceeds consumption, the surplus electricity can be fed into the grid, as in a conventional grid-connected (on-grid) system.
During periods of low solar production, the household can use the energy stored in the battery storage system.If the stored energy is insufficient, the remaining electricity is taken from the grid. With a suitable hybrid inverter and backup power solution, selected appliances can be powered with energy stored in the battery storage system during a power outage.Backup power options depend on the system configuration, inverter power and battery capacity.
The system manages energy use according to the configured control logic, production, consumption and electricity prices.
Solar energy generated and consumed on-site helps reduce the amount of electricity purchased from the grid and the associated variable energy costs.
If necessary, the system can be supplemented with a generator to increase the reliability of the energy supply during longer power outages. A hybrid system operates together with the electricity grid, while an off-grid system is designed to operate without a grid connection. The technical configuration of the solutions depends on the needs of the property and the selected equipment.
