Solar Charging
Store surplus solar generation for later use.
Your Energy Storage Solution
Storing Energyfor theFuture
Battery energy storage systems for industrial facilities and energy projects.
ENERGY BALANCE
Generate Now
Use When You Need
Solar generation changes throughout the day. YESS stores excess energy so it stays available after generation falls.
Daytime solar surplus is stored and used after sunset.

HOW STORAGE WORKS
Three Ways to Use Stored Energy
Match stored energy to your site and tariff.
Peak Shaving
Use stored energy to limit peak power drawn from the grid.
Grid Arbitrage
Charge at lower prices and discharge at higher prices, where tariffs allow.
Illustrative operating scenarios. Actual value depends on the site, tariff and system configuration.
