Hybrid inverters are very similar to standard, grid-tied inverters. These products, however, are fitted with a back-up battery system. Hybrid products simultaneously manage input from the panels and a battery bank, charging the batteries with energy from the modules or the grid. Any surplus energy can be stored in the battery cells for later use.
The hybrid inverters can:
- Rely on solar power alone
- Supplement mains power if demand is higher than the energy generated by the panels
- Charge the batteries if the power from the panels exceeds that of the load
- Distribute power back to the grid if the batteries are fully charged
