Sonnen solar battery has a warranty of 10 years or 10,000 cycles. Whichever comes first. However, this is just the warranty that is covered. It’s more than likely your Sonnen battery will last long than this. We estimate the battery to last at least 20 years. Within this time, you should have seen a significant return on investment from your solar battery. 

Technically yes. We’d also argue that Sonnen’s battery is possibly the best battery to choice to go off-grid with. However, on the other hand going off-grid itself might not be the best move. Simply put, going off-grid is expensive and might cause you more hassle than its worth. Getting your grid connection removed takes time and costs a lot. It’s not a bad idea to keep it incase you ever need it or for the rebate (FIT) you might get. 

Sonnen batterties are up there with some of the best solar batteries you can buy in the Australian market. They have a fantastic warranty (maybe the best in the industry) and use SMART technology which sets the apart from the crowd. You can read our full Sonnen battery review here.

One area that gives Sonnen a huge advantage is their chemistry. They use LFP chemical make up of the battery which is deemed much more safer than colbat or any other chemical make up. This means that they are the safest battery you can buy on the market and there is very little risk of fire or anything going wrong. 

Sonnen batteires are Australia made. They are manufactured in South Australia and assembled by Australians. In fact, interestingly enough they are made in an ex-Holden factory still using the same staff. This means the team are highly efficient.

Yes, you can add your Sonnen battery to any existing solar system. All you will need is an accredited Sonnen installer and they will be able to connect your battery to your system without any stress. Your existing system will not be changed in any way.
