Home storage - easy to integrate - smart, fast, reliable
With modern home storage systems, you can help your customers maximize the self-consumption of their photovoltaic systems and save electricity costs. These storage systems store surplus solar energy efficiently and increase independence from the power grid.
As an installer, you benefit from high-performance, easy-to-integrate storage systems with a long service life and intelligent energy management. The compact design and simple installation save time and effort.
Modern home storage systems also offer emergency power functions and remote monitoring, allowing you to offer your customers real added value and strengthen your role as a competent partner.
What is home storage?
Home storage systems are intelligent energy storage systems for private households. They store surplus solar power from photovoltaic systems and make it available exactly when it is needed - for example in the evening or when solar radiation is low. This significantly increases self-consumption, which reduces electricity costs in the long term and increases independence from the public grid.
Modern home storage systems are compact, efficient and easy to integrate into existing PV systems. In addition to a reliable energy supply, they also contribute to grid stability and promote sustainable, climate-friendly electricity use. They are ideal for homes, apartment buildings and smaller commercial units that want to improve their energy self-sufficiency.

Advantages of home storage systems
1. more energy independence
Home storage systems make it possible to temporarily store surplus solar power and consume it yourself when needed - in the evening or at night, for example. This significantly reduces dependence on the electricity supplier.

2. reduction in electricity costs
By using more self-generated electricity, the purchase of expensive grid electricity is reduced. This saves energy costs in the long term and increases the profitability of the PV system.

4. emergency power supply in the event of a failure
Many systems offer an integrated emergency power function or backup power solution. In the event of a power failure, they continue to reliably supply important consumers in the household with energy.

Disadvantages of home storage systems
1. high acquisition costs
The investment in a home storage system can amount to several thousand euros. Despite long-term savings, the initial investment remains a hurdle for many households.

2. limited battery life
Even modern lithium-ion storage systems are subject to natural wear and tear. After around 10-15 years, they may need to be replaced, resulting in follow-up costs.

3. efficiency losses during storage
Minor energy losses occur during charging and discharging. Not all of the stored electricity is available without loss.

4. space requirements and structural conditions
A home storage system requires a well-ventilated, dry room. In small apartments or old buildings, integration can be structurally challenging.

Technologies and innovations in home storage systems (2025)
In 2025,modern home storage systems will predominantly rely on lithium-ion batteries, which are characterized by high energy density, fast charging cycles and a long service life. New cell chemistries such as lithium iron phosphate (LiFePO₄) are also increasingly being used - they offer improved safety and thermal stability.
Another trend is solid-state batteries, which are characterized by even longer service life and safety and will become increasingly marketable in the coming years.
Intelligent energy management systems (EMS) with AI-supported optimization analyse consumption patterns, weather data and electricity prices in real time. This maximizes self-consumption and further reduces electricity costs.
Many systems are already smart home-compatible and can be easily operated via app or voice control. In addition, home storage systems are increasingly being networked with electric cars (V2H), enabling bidirectional charging - an important step towards active integration into the home energy supply.
