Battery systems for properties
Energy storage solutions for future properties – efficient, smart and secure
With Againity’s robust battery systems for properties, it is easy to increase preparedness for power outages while reducing electricity and grid costs and generating revenue from ancillary service markets. Increased profitability, while you focus on other priorities.
Efficient, smart and secure
We offer a complete base package of battery systems with a 20 kW inverter and 50 kWh battery storage, optimised to maximise self consumption of solar power. During sunny days, the battery is charged, and in the evenings and at night, the property is powered by stored energy.
Inverters and batteries can be connected in parallel with up to ten units, allowing system expansion up to 200 kW output and 500 kWh battery capacity. For additional security, off grid functionality ensures continued power supply during outages. The system can also be connected to frequency regulation services, stabilising the power grid while generating recurring revenue.
We manage the entire process, from initial notification to the grid operator to a fully commissioned installation.
Maximise the value of your solar energy year round
With Againity’s complete battery system, surplus electricity from solar panels is stored and used when needed most. This reduces electricity costs, increases self sufficiency and delivers a complete end to end solution with support throughout the process.
Benefits for you
- Lower monthly electricity bills by maximising the value of your solar panels
- Electricity during power outages to keep critical functions running
- Reduced dependence on electricity suppliers and volatile prices
- Revenue from participation in frequency regulation services
- Complete project delivery from grid connection to installation
- Ongoing support after commissioning
What does off grid functionality mean?
Off grid functionality, also known as island operation, means that your solar and battery system can continue to supply electricity even if the main power grid fails. During a power outage, the system automatically disconnects from the grid and switches to supplying the property with stored energy.
Benefits of off grid functionality
- Reliable operation during power outages
- Full control over your energy supply
- Fully automated operation

A reliable partner throughout the system lifetime
Againity has extensive experience in installing and controlling energy systems and has built unique in house expertise in power systems and control. Since 2013, Againity has delivered reliable energy systems with strong references in both electricity generation and energy storage. Againity supports you throughout the entire journey, from system design and installation to commissioning and long term service.
Simple installation tailored to your needs
Againity offers a wide standard portfolio of battery systems suitable for different types of installations, from small scale to large scale systems for indoor or outdoor placement. Indoor solutions include stackable modular battery systems for garages or storage rooms. Outdoor solutions are housed in cabinets designed for Nordic climate conditions to maximise battery lifetime.
Combine battery systems with vehicle charging to reduce fleet costs
The battery system can easily be complemented with charging stations for convenient and climate smart vehicle charging. With Againity’s solution, you can use your solar power or other stored electricity to charge vehicles around the clock. Additional units can be added later to meet growing demand.
