Store solar power and use it flexibly

Maintain your solar energy supply — even when the sun is not shining

Sometimes, the sun delivers more power than you currently need. You would normally feed in the surplus power back to your utility for compensation that is considerably lower than the current power prices. Sometimes, however, solar power is not available when you need a lot of power. This means that you would have to purchase expensive power from the utility grid. Storage systems allow you to use surplus solar power whenever you need it.

Utilize your solar power at night

Thanks to highly efficient storage systems, you can temporarily store electricity that is not needed immediately and use it later if necessary. This is a particularly attractive scenario when your utility enforces a time-of-use policy, which charges more for electricity in the evenings when there is a peak demand.

Benefits

Up to 45% lower energy costs

Consume more solar power yourself by storing what you do not currently need

Use free solar power even when your PV system is not producing any electricity

Greater protection against rising energy prices

Home Backup Power

Home Energy Management

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 affords 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

What are 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.

The solution?
Home energy management with the SMA Energy System

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.

Save up to 45% annually on electricity costs

Peace of mind with Backup Lite

With Backup Lite, the most critical appliances in your home can run day or night for the duration of the battery. This is exclusive to the SMA Energy System, and provides additional peace of mind and energy security to homeowners.

Typical time-of-use rate structure

Electricity costs more during times of peak demand, which is highest during the evening hours. This rate structure has an impact on both solar and solar + battery storage systems.

Solar power only

Solar power can only be consumed as it’s produced, otherwise it’s fed back into the grid and you’re credited for that power. However, the amount you’re credited varies based on the time of day. Excess power generated by your solar system is worth less during times of lower demand. The solar energy production curve peaks mid-day when the cost of power is at its lowest. Solar production has often ceased in the evening when the cost of power is at its highest, so during peak times you’ll purchase power from your utility when it’s most expensive.

Solar power + battery storage

Adding battery storage allows you to offset the effects of time-of-use pricing by maximizing your self-consumption. Power produced during the day is stored in batteries and used in the evening when the cost of power is at its peak. The value of battery storage can:

Increase your home’s annual energy cost savings by up to 45%
Decrease the payback period for your system by up to 16%

Solar power plus battery storage - time-of-use rate structure

System Details
SMA Energy Systems for your home allow you to store your solar power for later use.

PV system

The roof-mounted PV system modules convert sunlight to solar power.
SMA ShadeFix

SMA ShadeFix technology provides superior power production with a reduced component count versus competitors, which provides maximum reliability. Your energy yield is optimized without adding any additional, complex components to the system or PV modules. SMA ShadeFix is already integrated into SMA solar inverters and activated automatically during commissioning.
SMA Sunny Boy inverter

The SMA Sunny Boy family is the core of SMA Energy Systems for your home. It converts the direct current generated by the roof-mounted PV system to alternating current as required in your home. In addition, it ensures optimum energy usage so that you have to purchase as little additional power from your utility as possible.
SMA Sunny Boy Storage battery inverter

The SMA Sunny Boy Storage battery inverter ensures that surplus solar energy is stored in the batteries so that it can be reused as needed. SMA offers solutions for whole home backup power as well as home energy management solutions to offset the effects of your utility’s time-of-us pricing.
SMA Monitoring

Whether via the online portal or mobile app, you are constantly updated on the performance of the SMA Energy System for your home. You can also find out what the weather is like at the site where the system is located and the size of your CO₂ footprint.
Battery

The battery stores the solar power with maximum efficiency and makes it available again as required. You can use the stored solar power to watch television in the evening, charge your electric car over night or even to power your washing machine, dishwasher or other bulk consumers in the household without using additional grid power.
