Why Choose a sonnenBatterie EVO For Your Home

The sonnenBatterie Evo is the first battery from sonnen that is specifically developed as an outdoor battery solution for Australia and New Zealand. The Evo also features a proprietary intelligent Battery Management System and sonnenInverter, which was fully developed by sonnen to support demand response programs and Virtual Power Plants.

The battery capacity is especially useful during blackouts or periods where you can’t generate power. The Evo supports your home with backup power included for a 5kW continuous backup power and 7kW surge capacity. This is due to the Lithium Iron Phosphate (LFP) battery cell, customised by sonnen, known as the sonnenModule 4. This innovative design is made up of two fully usable 5.0kWh battery modules, resulting in 10kWh of usable storage capacity.

Sonnen’s innovative solar technology helps Australians to take control of their energy usage, avoid shocking electricity bills, and be part of the movement creating real change. 

What Is A Solar Battery?

A solar battery is an energy storage device that you can add to your solar power system to store solar energy. The stored energy from excess solar power produced can be used to power your home at night, on cloudy days, and during power outages.

Installing solar panels will save you money on it’s own, but adding a solar battery into a new or existing solar system and you will save significantly more now and over the long term. By storing the excess solar power generated by your system, instead of sending it to the grid, you can reduce your reliance on electricity from the grid and rely more consistently on the clean energy generated by you.

Intelligent Battery Management System

The BMS (battery management system) is an intelligent control system that protects the battery cells while in operation, to optimise performance and prevent faults/damage.


About sonnen Australia - A Global Leader in Solar Technology & Storage Solutions

The first sonnenBatterie was developed in 2010 by the company founders, Christoph Ostermann and Torsten Stiefenhofer. At this time, solar energy was only fed into the grid and sonnen was developed as a system to allow households to store and consume their self-generated energy – no matter the time of day or the weather. As a global leader in energy storage solutions, sonnen now has offices in Germany, Italy, Great Britain, the United States, and Australia.

The goal at sonnen is to refine the processes of solar power and energy generation ecosystems, storage and distribution to help solve the complex energy and environmental challenges of today and the future.

I was very impressed with HCB Solar and their attention to detail. There was an issue with my mains supply and potential issue with the solar integration but Anthony and the installation team were upfront and made sure there was a plan of action to investigate and rectify.

They never palmed me off, took full responsibility for the issue and ensured the solution would work. I am glad I went with HCB and got a premium product.
