Maximum efficiency and higher savings

The storage system allows you to optimize your energy gains in a smart way. 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 energy waste, higher yields, and significantly lower energy costs!

Maximum compatibility

In conventional DC-coupled systems, the storage inverter must 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 system completely eliminates the problem and also significantly increases energy efficiency. It can work with any micro inverter. Here are a few compatible models.
