Battery storage systems

A battery storage system for photovoltaics works in a similar way to a large rechargeable battery. During the day, the surplus solar power is converted into chemical energy and stored in battery cells. This energy is then converted back into electrical energy and used when the sun is not shining. An integrated management system controls the charging and discharging of the battery to maximize efficiency and protect the battery.

If the batteries in the storage system are fully charged and there is still a surplus of energy, this can be fed into the public electricity grid.

The duration for which a PV storage system can store energy is determined by several factors, including the capacity of the storage system, the connected load and the energy consumption. Typically, a PV storage system can store energy for a period of several hours to several days.

Yes, if you want to buy an electricity storage system, you will benefit from a number of advantages. An electricity storage system makes it possible to optimize self-consumption, gain independence from the power grid, contribute to reducing the load on the grid and promote the use of renewable energies.

Yes, if you want to buy electricity storage systems, you can benefit from subsidies. In Germany, there are regional subsidy programs that support the purchase of battery storage systems, often in conjunction with the installation of new photovoltaic systems. These subsidies aim to promote the integration of renewable energies and can significantly reduce the initial investment.

A battery storage system for the solar system is generally maintenance-free and can be used for the entire warranty period, which significantly increases the convenience and reliability of the power supply. To ensure optimum performance and energy density of the system over its entire service life of 10 to 15 years, regular maintenance by a qualified installer is recommended.

During maintenance, various parameters are checked and, if necessary, adjusted so that the solar system can operate without loss. It is important that maintenance is carried out by a professional who is familiar with the AC compatibility of the system. A thorough installation and maintenance of the battery storage system will help to maximize the lifespan and efficiency of the solar system.
