sonnenBatterie – Smart energy storage for homes

DCR are sonnen approved installers. We have experience in battery storage, training from sonnen and also tried and tested systems that are currently working for our customers. We are experts in sonnen Battery Storage.

sonnen are the award-winning, global market leader for energy storage with a mission to provide clean and affordable energy for all.

Since 2010, sonnen has been an innovator in intelligent energy storage products that help consumers reach their goal to use clean, reliable and cost-effective energy. The first sonnenBatterie came on the market in 2011 as the first fully-integrated lithium-ion battery storage system. sonnen now employs around 450 employees and has more than 30,000 sonnenBatterie systems installed in homes and businesses worldwide.

sonnen has also led the transition to a changed energy market through the sonnenCommunity – the first-of-its-kind decentralised energy sharing community where sonnenBatterie owners share their self-produced energy. The sonnenCommunity enables households to break away from their traditional energy supplier and become energy independent.

All included: high-end components perfectly tuned to your needs.

The sonnenBatterie is a complete system – ready for connection. This means that inside of every sonnenBatterie you’ll find not only the extremely durable battery modules but also an inverter, an intelligent energy manager, measurement technology and the software to operate it all smoothly. All in one handy box.

Create your own energy mix.
The sonnenBatterie isn’t limited to storing energy generated by a PV system. A micro-cogeneration plant generates energy and heat. Just connect it to the sonnenBatterie to store its energy when the sun isn’t shining. Since you are generating heat too you’ll be even more independent.

A sonnenBatterie can be combined with wind generators, heat pumps and fuel cells. So regardless of the energy concept you decide on for your home, the sonnenBatterie can be part of it.

The right size energy storage for any need – any time.

Every household has its own energy requirements. That’s why the sonnenBatterie was developed as a multi-stage storage system that can be adapted to most energy needs. With storage sizes ranging from 2 kWh to 16 kWh the sonnenBatterie will power a detached house, a multi-family house or an apartment block. The capacity of the sonnenBatterie can be expanded in blocks of 2 kWh.

Should you require more power – for example for running a small business – multiple sonnenBatterie can be set up as a cascading cluster thereby increasing the capacity and power of the sonnenBatterie up to a maximum of 48 kWh. More than enough to satisfy the energy needs of your business.

The sonnenBatterie eco delivers savings and peace of mind day and night.

Use solar energy at night.

sonnenBatterie eco lets you enjoy the benefits of solar energy production 24-hours a day! Our integrated smart electronics manage energy use throughout the day, detecting when there’s excess power and storing it for use at night.

Harvest cheaper energy to use later.

sonnenBatterie eco 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 eco is the right choice for every home and every budget.

Never worry about the lights going out.

Electricity blackouts are quite rare in the UK and will only last a couple of minutes, or hours at the most. Even so these outages are always unpredictable and can cause problems. With the emergency power supply sonnenBatterie protect you are safe. It will reliably supply your household with stored energy during these power failures. Order sonnenBatterie protect as an option when buying your sonnenBatterie or upgrade to it later.

Gain energy autonomy.

A sonnenBatterie eco integrated with solar panels allows your home to produce and store 100% of the energy it uses – depending on climate and sun exposure – enabling your home to be energy self-sufficient.

How the sonnenBatterie grants you independence.

The sonnenBatterie will store the surplus energy generated by your PV system in times when you don’t have any need for it. The stored energy from the daytime is then at your disposal in the evening and during the night. But the sonnenBatterie is much more than just a battery, it’s an intelligent storage system that automatically adjusts the energy use so that most of your self-generated solar energy stays in your household.

Morning: minimal energy production, high energy need.

At sunrise the solar panels start to produce energy, though not enough to cover the morning energy need. The sonnenBatterie will bridge the gap with the stored energy from the day before.

Midday: highest energy production, low energy need.

In the daytime the solar panels’ energy generation is at its peak. But since nobody is home the energy consumption is very low so that most of the generated energy is stored in the sonnenBatterie.

Evening: low energy production, high energy need.

The highest daily energy consumption is in the evening when the solar panels produce little or no energy. The sonnenBatterie will cover the energy need with the energy produced in the daytime.

The sonnen App

With the sonnen App you can manage and control your energy consumption and production. Download the sonnen App to your smartphone or tablet for access to your sonnenBatterie smart energy storage system.

The App allows you to monitor, analyse and control the supply and demand of your household or business – anytime, anywhere.

Quality ‘Made in Germany’.

Engineered in the energy village Wildpoldsried, the sonnenBatterie is one of the world’s most popular lithium based energy storage systems. Many thousands of households are using the sonnenBatterie today to safely store their self-produced energy. As a product ‘Made in Germany’, the sonnenBatterie fulfils the highest demands of safety and quality thus protecting your investment in the long run.
