We’ve selected the optimal balance of power, capacity, and reliability — so you don’t have to.
At Sunsa, we support Estonian households and businesses on their decarbonisation journey — by providing clean, silent, and reliable temporary power that lowers emissions and cuts fuel dependency.
The system charges from solar or off-peak grid power, then discharges during outages or high-price periods — reducing both your bills and your carbon footprint.
We also assist with hybrid setups and future-ready integrations — because sustainability shouldn’t wait for permanent infrastructure.

It’s a complete, containerised battery energy storage system with a 60 kW inverter and 200 kWh of usable lithium (LFP) capacity — ready to connect to your home or business grid.
A typical Estonian home uses 10–15 kWh per day. With 200 kWh, the system can run essential loads (fridge, lights, internet, heating circulation pump) for 5–10 days — or full comfort for 1–2 days.
Yes. It integrates seamlessly with existing or new solar systems — storing excess daytime energy for night or outage use.
