AC battery storage
Simply retrofit. Benefit immediately.
The ideal extension for your existing photovoltaic system. Our AC storage is compatible with any inverter and makes your home energy-independent in no time.
AC coupling
AC coupled system, operates independently from your existing inverter model. The perfect solution for any retrofit project.

Quick installation
Thanks to the plug-and-play principle and the integrated inverter, the system can be quickly installed and ready for use. Without major renovations.

Immediate autonomy
Save excess solar power immediately and increase your self-consumption to up to 70% – without waiting time.

Save costs through self-consumption optimization
Your energy in sight. Anytime.
Modual storage can be seamlessly integrated into leading energy management systems such as the Solar Manager. Monitor your energy flows conveniently via app, control consumers intelligently, and maximize your self-consumption – fully automated and transparent.
App Integration
Visualize production and consumption through the Solarmanager app. Everything in one interface, perfectly connected with the heat pump and electric car.

Why lithium prices are rising again and what that means for battery costs
Lithium has become one of the most volatile raw materials of the energy transition. After a dramatic boom-and-bust cycle that has reshaped the battery industry, prices are rising sharply again in 2025–2026. For anyone investing in or specifying battery energy storage systems, it is becoming increasingly important to understand what drives these fluctuations and what protects against them.

From the electric truck to the grid
From an evaluation project for e-trucks of a partner company, eight large traction batteries with a nominal capacity of 560 kWh were recovered for a second life. The areas of application for these batteries are highly limited, making them unattractive for smaller applications, especially since they could only function when connected as clusters of 4 batteries. Therefore, it was clear that a large storage system should be created from this, which can stabilize the Swiss power grid.
