Property Batteries offer indepence, savings, and reliable energy storage for sustainability.

Eco-Friendly Technology

The combination of solar panels and property batteries contributes to a more sustainable and environmentally friendly energy system. By maximizing the use of solar energy and reducing reliance on traditional grid power, the carbon footprint associated with energy consumption is lowered.

Savings during wintertime

Property batteries can contribute to cost savings by reducing electricity bills. Energy can be stored during cheap hours and used during peak times, avoiding higher electricity rates. Intelligent Rebelvolt software optimizes storing and using automatically.

Savings in summertime

In summertime, solar panels generate ample energy during peak sunlight hours. A property battery enhances this synergy by efficiently storing excess solar energy during the day, ensuring optimal utilization. As the sun sets or during periods of lower solar output, the stored energy can be tapped, providing a continuous and reliable power supply.


By storing excess energy, property owners can reduce their reliance on the grid, leading to greater energy independence. This is particularly beneficial in areas with unreliable or expensive grid electricity.

Property Batteries are the future!

"Solar panels alone are just not enough. Without batteries the advantage is too small. With batteries you can be energy-independent from April to September. From October to March you can minimize your energy costs with our intelligent software."

Pekka Karppanen, founder of Rebelvolt

How does it work?

Property batteries during summertime.

1. Energy consumption. 2. Energy from solar panels. 3. Energy stored in batteries. 4. Energy from batteries.

During the summer, your property can be energy self-sufficient. In that case, you won't buy energy from the grid at all. The excess energy produced by solar panels during the day is stored in batteries and used for your property's needs when the sun isn't shining.

In the winter, your advantage is based on the fluctuation of the electricity market prices. Electricity is generally cheaper at night and more expensive during the day. There are also unpredictable spikes in electricity prices, during which electricity may cost even several euros per kilowatt-hour. The property battery is your way to protect yourself from unexpected costs.

Our mission is to save your money.
