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.

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.

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.

How The sonnenBatterie Increases Your Energy 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.

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

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

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

Monitor your energy supply with the sonnenApp

sonnen energy monitoring

With the sonnenApp, you’ll be able to check your energy usage and production – anytime and from anywhere.

Use the sonnenApp on your smartphone or tablet to connect to your sonnenBatterie via the internet and to monitor, analyse and control the supply and demand of your household.


This system may qualify for sonnenFlat

sonnenFlat is an invitation to a renewable energy community

With energy prices continuing to rise, households across Australia are taking matters into their own hands. sonnenFlat is an invitation to a self-sufficient energy-driven community where you can enjoy $0 cost of energy.

Instead of paying for electricity from an energy retailer such as AGL or Origin, you can now join the new sonnenFlat network and replace your power bills from as little as $30 a month. The network operates as a free exchange of power between all customers and is managed entirely by sonnen behind the scenes, with no disruption to your energy supply.

Each customer who signs up for sonnenFlat contributes towards the daily exchange of power through their home energy generation.  Sonnen provides free electricity by leveraging the network. To understand how this works in practice, imagine sonnen as a central battery. sonnen charges this battery by collecting small incremental charges from each individual sonnenBatterie in the network. They then distribute this stored energy to customers who are not generating enough power for their individual needs at that time.

As a part of the ecosystem, your household becomes entirely self-sufficient through your contribution to the community.

How do I join sonnenFlat?

To qualify for sonnenFlat you must meet the following criteria:

  1. A new or existing solar system (any brand) with a minimum size of 5.0kW or higher
  2. A sonnenBatterie eco 8.8 (8kWh) or above
  3. Successfully register on the sonnen website after your installation

Below are the three sonnenFlat packages available in Australia.

The table below shows the minimum size solar system your home requires and the corresponding sized sonnenBatterie.

Depending on which tier you allocate to will determine your yearly flat fee.

Note: sonnenFlat spaces are limited to the first 2,000 customers and rates may increase thereafter. Be quick to secure these prices while they last.
