Pay No Bills for 2 Years

Install a sonnen solar battery system and you can relax knowing you won’t be paying a power bill for the next 2 years. 

Our sonnen battery solutions are a great solution to ensure you are getting the most out of the clean energy you produce. You can store all the power you produce and use it when it suits you, including at night and even if the power goes out!

Already have solar? We can add a sonnen battery to your existing system and you are still eligible for 2 years free energy. Contact us to see if a battery storage solution is right for you.
