This is a real installation in Gabčíkovo: five SolisStorage EverCore battery units, each holding 261 kWh—1,305 kWh, or 1.3 MWh in total. The configuration is modular and scales to the size of your operation. From design and delivery to commissioning and training, everything is handled by one partner, Onsa Plus—no juggling distributors and manufacturers, not even for service or claims.

Beyond savings, the system delivers backup power during outages and more predictable costs going forward, no matter how the electricity market keeps changing. Using a model savings calculation, a single 261 kWh unit typically models roughly €10,000 a year in savings—without solar or subsidies—while the full five-unit setup reaches tens of thousands of euros a year. Real savings depend on your consumption, tariff and energy prices, and Onsa Plus will calculate the exact figure for your business from your real data.
