SMA Battery

The SMA Energy System

The SMA Energy System can provide backup power and on-demand energy. The system consists of a Sunny Boy grid-tied inverter with solar panels, the Sunny Boy Storage inverter with batteries, and the Automatic Backup Unit to connect everything to the house. Monitoring is handled through the Sunny Portal. The grid-tied inverter works with most any type of solar panel, while the storage inverter works with high-voltage lithium type batteries like the LG Chem RESU or the BYD B-box H10.

Backup power and energy management for your home

Backup power provides a critical lifeline to families living in storm-prone regions, areas where natural disasters can occur and places where the electrical grid is simply unreliable. However, not all backup power systems offer the same level of quality and reliability. With the SMA Energy System, you can rest assured your home’s energy infrastructure will remain intact in the event of the unforeseeable.

How does the SMA Energy System backup power work with my solar system?

In a standard solar installation, your home is connected to the public utility grid. While the grid is up your system can freely produce energy for your home’s usage and it can also feed energy back into the grid or charge your batteries. In the event of a power outage, the SMA Energy System will instantaneously disconnect from the grid and provide seamless backup power to your entire home.

The SMA Energy System offera two options for backup power, depending on the needs of your family. Achieve whole home backup for the ultimate peace of mind during power outages. Backup protected loads to ensure power is accessible to important devices.

Home energy management for time-of-use utility rates

Many electric utilities have moved to a time-of-use rate structure. This means the price of power is high when demand is high—but it’s not just the time of day impacting your power bill. The day of the week, and even the season, impacts pricing. Managing your power costs is complex because your home’s solar system is producing the most energy during daytime periods of low demand when electricity is worth the least amount of money.

Adding battery storage to your solar system offsets the effects of time-of-use rates and maximizes the usage of electricity your system generates. It’s simple: energy produced during the day is stored in your batteries and used in the evening when the cost of electricity is higher. This is called energy selfconsumption, and it can save you up to 45% annually on your electricity costs! What’s more, energy management from the SMA Energy System includes the proprietary Backup Lite feature.
