Industry-leading battery locally manufactured

Sharpe Energy Hub is proud to have our pioneering sonnenBatterie hybrid 9.53 certified Australian Made in Elizabeth, South Australia, dedicated to building safe, reliable home battery storage systems and accessories.

The combination of over 10 years of German innovation in design and engineering, along with local production expertise in Australian manufacturing has helped us deliver thousands of quality and intelligent home battery storage systems across Adelaide.

Sonnen pioneered the sleekly-designed, AC-coupled battery being one of the first lithium solar battery solutions in the market in 2010.


Lithium ion phosphate occurs naturally and does not contain any toxic heavy metals.

It is 100% recyclable.

The highest Safety Standards

Safety is an important consideration when purchasing a battery. You need the reassurance that anything you add to your home will be safe.

sonnenBatterie is based on the most reliable and sustainable battery technology available.

100% Cobalt-Free. Exclusively uses lithium ion phosphate batteries (LiFePO4) – which is long-lasting and the safest in the market!

The most Flexible Storage Size to save you money

The Size of the battery will reflect on the price.

So, make sure you are not paying for something you won’t use to its full capability.

SonnenBatterie will give you great flexibility as it starts at 5kWh, giving you possibilities to upgrade to 7.5, 10, 12.5, and 15kWh after!

Flexibility of size relates to cost – if you only need 10kWh of storage, you don’t have to pay for extra your household will not need. Other batteries might not offer you the flexibility and suggest just 1 size (eg. 13.5 kWh).

The best warranty in the market!

Be aware that some brands in the market might offer a 10-year warranty, but actually only offer throughput warranty. Some brands offer ProRata Warranty, not replacement warranty.

Why buy something else if you can buy the best warranty offered by sonnenBatterie?

sonnenBatterie is designed to last up to 27 years. One full charge-discharge everyday will give you an estimate lifespan up to 27 years.

10,000 Cycles

The sonnenBatterie will also still be at 80% after 10 years. Which gives you an absolute peace of mind. Be mindful as well that some batteries might have quicker charging cycles which means they could charge and drain up to 3 times a day leading a battery to wear out faster.

10 Years

The warranty of sonnenBatterie covers the first 10,000 charging cycles or the first 10 years. Which ever comes first

Never worry about the lights going out

Solar power generation does not have to go to waste. When the grid goes down – with Black Start function, you can rest assured knowing that during the blackout, the sonnenBatterie hybrid 9.53 can restart itself after a full shut down, and utilise the energy from the directly connected solar system, to ensure you have continuous backup energy supply. Meaning you can use your essential appliances without interruption during times of extended blackouts**.

This accessory is an additional component. You can discuss with us to install or add it

** The ability of the sonnenProtect to power essential loads is dictated by the battery capacity, SOC and availability of Solar PV production.. 

No hidden costs – everything comes in one box

Sonnen offers a hybrid AC-coupled battery. 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 comes in one box!

All in one handy box. In contrast to most other battery systems in the market that are AC coupled batteries, which require a separate solar inverter (e.g. Fronius). sonnenBatterie comes with everything you need, just add panels.

This is how sonnenBatterie can get you $0 Energy Bills

Typically, this is what the electricity used for a four-person household looks like over the course of the day. Electricity consumption is usually high in the morning, while it drops off at the midday when people go to work. In the evening, power consumption increases again when families return back home, while solar produces the electricity ONLY during the day when most of the people are at work and don’t use it. Think about it! That is why people with solar still pay high energy bills. What is the missing energy puzzle piece you might ask? Well.. you will know the answer very soon!

It all changes when you add a battery, that can be charged by your solar panels during the day when the sun is shining and you are not at home to use all the electricity. What is more important, the battery stores the power for your later use. For example, for evening time when you are back from work and your solar NO longer produces any electricity, a battery will provide essential power needed for your home. This increases the usefulness of the energy your solar generates, and might save you up to 100% on your energy bills. How does that sound to you?  

Most of our customers drop their energy bills by 90% without increasing their family monthly spend. Come and talk to our highly professional experts and engineers to find out how.
