What is a sonnen batterie?

The sonnenBatterie is an intelligent domestic battery storage system that can help you reduce your monthly electricity bills.

When you combine your solar panels with a sonnenBatterie, you can store the solar electricity that you don’t use during the day.

It’s then available to you in the evening or at night - so you’ll use less energy from the grid and save money on your electricity bill.

Who will install the sonnenBatterie and how long will it take?

sonnen partners with a network of approved installers, one of whom will install the battery storage system and answer all your technical questions. A standard installation usually takes three to four hours but will depend on the complexity of the installation. 

What are the general installation requirements?

A sonnenBatterie can be installed almost anywhere indoors. Common locations are utility rooms, hallways, cloakrooms, offices, kitchens and garages.

How much does it cost to install sonnenBatterie?

The cost of installing a sonnenBatterie system can vary, depending on the battery capacity and complexity of installation. A sonnen approved installer will provide you with a personalised quote based on your Solar PV system size and home energy usage.

A typical price for a fully installed 5kWh sonnenBatterie starts from £6,499 inc VAT.

sonnenBatterie warranty

A sonnenBatterie comes with a warranty of 10 years or 10,000 charge cycles. The performance guarantee states that the battery will be not less than 70% of its installed capacity after 10,000 cycles. 

The sonnen warranty is available to download from the sonnen website.

Power in the power cut?

If your home is suitable, sonnen expert installers can install additional controls to allow your battery systems to operate in a mains power cut.

Will I see a reduction in my energy bills?

You’ll be able to store surplus solar electricity generated during the day for later use, reducing the amount of electricity you draw from the grid and, therefore, reduce your electricity bill. How much you save on your energy bill will depend on your individual solar PV system and energy usage.

What if I don't have Solar Panels installed? 

sonnen approved installers can help by discussing your system requirements and providing you with a quote. 

Do I have to be a Shell Energy feed in tariff (FITs) customer?

No, you can continue to receive government subsidy from your current supplier.
