Battery Backup

Battery Backup System

Power outages are always inconvenient and often dangerous.  Without a battery backup system, your solar system will not work if the grid goes down.

Although grid-tied systems can save money and earn their owners incentives while the sun is shining and the utility power grid is up, they automatically disconnect when the grid is down during an outage as a safety feature within generic grid-tied systems, leaving unused solar electricity sitting on the roof.  When the grid is down, users can neither sell energy back to the utility, nor supply their homes or businesses with power.

By adding a sonnenBatterie backup system you can continue to use your solar power even during grid failures.

Worry about the lights going out with a sonnenBatterie system.

sonnenBatterie is specifically designed to provide you and your family peace of mind in the event of a power outage. Their unique power detection system will sense outages in real-time and automatically switch over to battery power!

sonnenBatterie also allows you to engage in “rate arbitrage” – storing energy when it is cheap and running your home off the battery when rates go up.

The sonnenBatterie residential and commercial storage systems only use lithium-iron phosphate (LiFePO4) battery technology, one of the most reliable, safe and long-lasting lithium battery technologies currently available. LiFePO4 is one of the most popular technologies for stationary storage systems due to its uniquely high chemical stability and resulting extremely high application reliability, durability and long life. Our battery systems are guaranteed to last for 10,000 cycles or 10 years. All sonnenBatterie components and systems are also UL Listed ensuring safety and performance for your home or business.
