How does an energy storage with a photovoltaic installation work?

How does a photovoltaic installation work?

The cooperation of the photovoltaic installation with the energy storage helps to optimize the use of solar energy. Photovoltaic panels convert solar radiation into electricity, which can be used immediately for your own needs to power devices. Unused energy is usually sent to the power grid.

However, the energy store captures excess energy and stores the energy for later use. All energy is to be used later, e.g. after sunset, in the evening or at night. It also allows photovoltaics to operate at too high voltage. Thanks to this, energy storage increases self-consumption and reduces dependence on the power grid.

Is it worth investing in a photovoltaic installation?

Victron energy storage devices can work with any photovoltaic inverter, but they offer the best compatibility with Fronius or SolarEdge inverters.
