All about sonnenFlat

SonnenFlat is a World first and will definitely shake-up the Australian market. Choosing sonnenFlat as your electricity distributor effectively caps your electricity expenses at $30 to $50/month depending on consumption.  You also have to factor in the cost of the sonnen solar battery you have to purchase to get your expenses capped.  Solarpro’s view is that it is worth it.  Even if you don’t go for the sonnenFlat deal, you are purchasing an amazing solar battery that can cycle three times a day.  As a household you will be capable of producing a lot of solar generated electricity for your own use or to send to the grid.  Prices for the purchase of solar power by the grid have improved recently.

How to Join sonnenFlat

To become a part of the sonnenFlat solar power production community you must have one of the following packages.  Starting at a 5kW solar system with an 8kWh sonnenbatterie eco 8:

sonnenFlat 8 sonnenFlat 10 sonnenFlat 12
Minimum solar (kW) 5.0 7.5 10.0
sonnenBatterie eco 8kWh 10kWh 12kWh
Monthly fee $30 $40 $50
Annual spend $360 $480 $600
Consumption allowance in kWh 7500 10000 12500

A Renewable Energy Community

SonnenFlat is a network operating 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. Instead of paying for electricity from an energy retailer who provides power from an unsustainable source such as coal, each customer who signs up contributes towards the daily exchange of power through their home energy generation.

The sonnenBatterie eco can cycle three times a day.  Most of the time you will not need this amount of power.  Sonnen collects the excess incremental charges from each individual sonnenBatterie in the network. Sonnen then distribute this stored energy to customers who could not generate enough power for their individual daily needs.

Why Choose Sonnen

Evidence based Performance: SonnenBatterie eco 8 is an all in one solar battery system developed about a decade ago specifically for home solar storage.  This battery is  designed to cycle three times a day.  This potentially gives you the ability to provide excess power to the grid or virtual power plants.  Just think about it.  We have a failing grid.  What ever solutions are put in place, people will need power.  Why not from solar producers? The early sonnen systems are still going strong and we are confident this is a battery you are investing in for 20 years.

Capacity & Kilowatt hours: The sonnenBatterie eco 8 has a capacity of up to 16kWh. It has been designed specifically as a home energy storage battery.  Therefore, over the life of the battery it can provide more than double the kilowatt-hours of comparably priced systems which were not designed for homes.

Flexibility: It can be retrofitted to an existing solar inverter or installed with a new solar system in Single and Three Phase homes. The system contains an inverter, lithium iron phosphate batteries and a predictive energy manager (intelligence for solar batteries).

Market Leader: Sonnen is the global market leader for smart energy storage systems.  They installed the World’s first lithium iron phosphate home solar battery eight years ago and have since installed over 20,000 in homes across Europe, the USA and now Australia.

Why Choose Solarpro

Solarpro puts value for money for its customers above everything.  We see advantages in being the local company backed by a larger organisation, provided they meet our criteria for partnership.

We seek organisations with innovative products or solutions to high energy prices.  We research the companies to ensure they are as financially robust as possible.  Recent partnerships include SolarEdge, Solartherm, LG, Tesla and of course sonnen.

Sonnen has selected Solarpro as its partner for the Northern Beaches and North Shore.  We are booking installations now. For further information and a quote Contact Us.

SonnenBatterie eco 8 System

The battery is the heart of the storage system, they will charge and discharge many thousands of times over the life of the system.  It is important to have the most reliable and sustainable battery technology. The sonnenBatterie eco 8 system offers just this.  It exclusively uses lithium iron phosphate batteries (LiFePO4). These batteries last longer and have a higher safety performance than most other lithium-ion batteries that are used in laptops, smartphones and electric cars. Lithium iron phosphate occurs naturally and does not contain any toxic heavy metals.

What you get

The Base Cabinet contains the inverter, a lithium iron phosphate solar battery module, an intelligent energy manager, measurement technology and software that ensures it all works smoothly. The components are built into one top quality casing and perfectly attuned to each other.  This ensures maximum life and the highest quality.  The Base Cabinet dimensions are: 70 cm (h) /64 cm (w)/22 cm (d).

Start Small and Expand

The sonnenBatterie eco 8 is easily adaptable to your individual needs. The system is available in a variety of storage capacities and configurations allowing for flexibility and expansion from 2kWh up to 16kWh.

The Solar Battery that Learns How You Live!

The sonnenBatterie eco 8 will store the surplus energy generated by your solar power system when you don’t need it. The stored energy from the daytime is then at your disposal in the evening and during the night. However, the Sonnen 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. For example:


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


During the day solar panels’ energy generation is at its peak. If nobody is home the energy consumption is very low so that most of the generated energy is stored in the Sonnen batteries.


The highest daily energy consumption is usually in the evening when the solar panels produce little or no energy. The Sonnen system will cover the energy produced in the daytime.

Peak and off-Peak prices

The Sonnen enables you to store energy when it is cheap and run your home off the battery when rates go up. However, for an average household you should no longer have to worry about different price rates because you will be consuming your own power and the sonnenFlat deal provides for any electricity you need from the grid above your solar output.

Appliance Selection

You are able to select which appliances you particularly want to run from the battery e.g., the fridge.


Sonnen Protect is an emergency power supply that will reliably supply your household with stored energy during grid power failures. Order Sonnen Protect as an option when buying your Sonnen system or upgrade to it later.


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