Maximum efficiency and higher savings

Optimize your energy yields intelligently with the storage system. Plan the use or storage of solar power at the most cost-efficient times and avoid expensive peak prices. In combination with Shelly 's smart sockets and meters, you always have an overview of your consumption statistics. The result? No wasted energy, higher yields and significantly lower energy costs!

Maximum compatibility

With conventional DC-coupled systems, the storage inverter has to precisely match the DC power flow from your panels to the MPPT algorithm of the micro inverter. The MS-A2 was developed to avoid all of this. The innovative balcony power plant storage unit completely eliminates the problem and also significantly increases energy efficiency. It can work with any micro inverter. You can find a few compatible models here.
