Photovoltaic system on the roof, battery storage system in the basement: in private households, residential storage systems are often operated in combination with a solar system. In addition to the inverter and string combiner box (SCB), this efficient system also includes the residential storage system itself, which consists of a battery management system (BMS) and the battery modules. Phoenix Contact has the right solutions for all of these areas of application.
Reliable installation and smooth operation of residential storage systems
Robust solutions for protection against surge voltages and lightning strikes
Efficient conversion of direct current into alternating current
Optimum protection for electronic components against external influences
With a residential storage system homeowners can use a large part of the solar-generated electricity themselves. This helps to protect the environment while also cutting costs.
If you have a photovoltaic system installed at home, storing the solar power in your own battery storage system is much more economical than selling the solar power at a low rate to the local power provider. The electrical energy is drawn upon as required and the electricity from the photovoltaic system is used within the household to operate a heat pump or to charge an e-car, for example. Electrical energy generated via the photovoltaic system reduces the amount purchased from the power provider and increases independence from the power grid. In addition, power outages can be bridged with the help of the energy storage system.
A residential storage system is an energy storage system that stores excess energy, usually generated from renewable sources such as solar power. This energy can then be used later when needed, e.g., at night or in bad weather. The storage system usually consists of batteries that store the electrical energy chemically. The storage capacity is in the range of 10 kWh.
There are various technologies for residential storage systems, including:
• AC-coupled systems: These systems are connected to the home grid via alternating current (AC) and can be installed independently of the solar system.
• DC-coupled systems: These systems are connected directly to the direct current (DC) of the solar system and provide more efficient power transmission.
• Hybrid systems: These systems combine both AC and DC coupling and provide flexibility and efficiency.
Residential storage systems bring several advantages, including:
• Energy independence: They make it possible to use more of the self-generated energy and to be less dependent on the public power grid.
• Cost savings: Electricity costs can be reduced by using the stored energy, especially at times of high electricity prices.
• Environmental protection: They promote the use of renewable energy and reduce carbon emissions.
