Battery Backup

with BBattery Backup Energy Storage for your Solar Energy

Energy storage and battery backup provides you peace of mind. With an energy storage system for your solar, your life isn’t interrupted when the power goes out. In the Carolinas, solar systems without energy storage systems stop providing energy when an outage occurs as a safety precaution, preventing injury to neighbors and energy grid workers.

With battery backup, your solar system will be able to continuously keep your house running in a closed loop system. Once the power has been restored, things go back to normal – you use your solar power or grid power, and charge your battery banks from your solar.

Be 100% Self Powered with Battery Backup


If The Power Goes Out in The Middle of The Night

The charged battery powers your kitchen and critical appliances such as your coffee maker and garage door opener so you can get to work on time. You have hot water and can charge your cell phone, perhaps you can run a single air conditioning unit. With minimal impact on your energy use, you can enjoy a normal day.

The Power Goes Out for 3 Days

Your solar system provides power to charge the battery. It allows you to use energy during the day while charging the battery to use at night. If you want, your fridge stays on. You don’t have to worry about eating all the ice cream, or what to do with wild game in that garage freezer!

Renu Energy Solutions has trained professionals who will make sure your battery is configured to stretch your stored power as long as possible in the event of a multi day-long outage. Our team will work with you to make your that the essential powered services in your home that you rely on.

Everyone uses energy differently, and depending on what you need most your battery can be sized to help sure your energy outlasts the outage. Your kitchen appliances, garage door, maybe your bedroom air conditioner unit, and critical electronics – can stay energized until the power has been restored. You can even set up your battery with special programming to help you make the most of your solar and avoid using more utility power than you have to.

Battery Backup or Generator? Know Your Options and Decide For Yourself

Some homeowners find solar energy especially attractive because it can provide a source of energy to fall back on if the grid goes down; however, for safety reasons, it is necessary here in the Carolinas to pair your solar with battery storage in order to use your solar energy during a utility outage.

If you own a propane or diesel generator, you already have a backup energy source should the lights go out. An energy storage product, like the sonnenBatterie or Tesla Power Wall, represents an alternative to gas-powered generation to provide power for critical purposes in an emergency, like refrigeration to chill medications and keep food fresh, or running medical devices or wifi.

Energy Storage for Time-of-Use Utility Customers

There are also situations in which sophisticated new batteries can save you money. A customer on a time-of-use electric rate schedule will start to notice that there are certain periods of the day when using energy from the grid it is much cheaper or much more expensive.

Ordinarily, this would force the customer to adapt their behavior to use less energy when it is priced higher, for example waiting until night time to run the dishwasher or clothes dryer. New home batteries can automatically store the energy from your solar array for use at expensive peak pricing times.
