The most expensive and complex type of solar power systems. It consists of an array of solar panels, a battery charge/discharge controller, the battery itself, and a hybrid inverter.
Direct current from solar panels first gets to the battery charge/discharge regulator, which charges the battery in a favorable mode or keeps it in a standby mode (a state of recharging). Surplus electricity is fed to a hybrid inverter, which sends it to the domestic power grid, which is a priority consumer. You can sell the non-consumed electricity as well.
If the public power grid is damaged, the hybrid inverter switches to the off-grid mode, so household appliances (house/apartment) can be powered by the battery.
Most modern hybrid inverters can be adjusted so that they 'inject' electricity from the battery into the domestic power grid at the right time. For example, when the electricity price is the highest.
Hybrid inverters can also be installed when it is necessary to increase the power of the domestic power grid. For example, if the maximum power allocated to a house is 10 kW, but there is a need to simultaneously turn on electrical appliances with a total power of 15 kW, the hybrid inverter will 'add' 5 kW of power from the battery.
