Store energy and earn
Modern battery systems let you store solar energy and use it when you need it most. Join the frequency market and turn your battery into a source of passive income.
More than just energy storage
A battery system is no longer a luxury—it’s a smart investment. Add a battery to your solar system and turn it into a fully featured energy hub that works for you 24/7.
Energy independence
Store the energy you produce during the day and use it in the evening and at night. Reduce the amount of energy you buy from the grid by up to 80–90%.
Frequency market revenue
Participate in the frequency market and earn an extra €500–€1,200 per year. Your battery helps balance the grid—and you get paid for it.
Outage protection
Keep your home powered during grid outages. Essential devices and systems continue running without interruption.
Optimize self-consumption
Make the most of the energy you produce. A battery ensures nothing goes to waste and helps you save more on your electricity bill.
Long lifespan
Modern LiFePO4 batteries last 10–15 years or 6,000+ cycles. A 10-year manufacturer warranty provides extra peace of mind.
Safe and eco-friendly
LiFePO4 technology is safe, stable, and environmentally friendly. It contains no hazardous materials and has a very low fire risk.
Smart energy management 24/7
The battery system automatically optimizes energy use, storage, and export. Everything runs in the background—without you needing to do anything.
Daytime
Solar panels produce energy. First, your household is powered, then the battery charges. Any surplus is exported to the grid.
Evening
When solar production drops, your home runs on the battery—so you can keep using power without buying from the grid.
Night
The battery supplies energy as needed. If it runs low, the system seamlessly switches to grid power.
Frequency market
If your battery is connected to the frequency market, it helps stabilize the grid—and you earn automatic revenue.

Earn passive income from your battery
The frequency market is a service where the grid operator pays you for allowing your battery to help balance the electricity grid. When the grid needs extra power—or needs energy absorbed—your battery responds automatically.
Automatic extra revenue
Earn €500–€1,200 per year depending on battery size and market conditions. Everything runs automatically—the system responds to grid needs and earns for you.
A fast-growing market
The frequency market is evolving rapidly. Early adopters benefit from better positioning and stronger long-term returns.
Easy to join
We handle everything—from registration to selecting a service provider. After setup, the system runs fully automatically.
Doesn’t affect everyday use
Frequency market participation doesn’t limit normal battery use. The system ensures you always have enough energy for your own needs.
What you should know about battery systems
Chemistry: LiFePO4
We use lithium iron phosphate (LiFePO4) batteries—the safest and most durable lithium technology. Long lifespan, stable performance, and maximum safety.
Cycle life: 6,000+
Our batteries deliver over 6,000 charge cycles—typically 10–15 years of real-world use. That’s significantly longer than older technologies.
Warranty: 10 years
All battery systems come with a 10-year manufacturer warranty covering both capacity and power. A reliable long-term investment.
Efficiency: 95%+
Charging and discharging happens at over 95% efficiency, meaning minimal losses. Almost all stored energy is usable.
Response time: <20 ms
The battery switches on in under 20 milliseconds during an outage. It’s so fast that devices don’t notice the interruption and keep running.
Temperature tolerance
Stable operation from -20°C to +50°C. Estonia’s climate is well-suited for maximum battery lifespan and performance.
