Sonnen Battery
sonnen batteries store excess solar energy so you can use it whenever required most, lowering external dependence, reducing energy costs, and improving energy self-reliance
Store extra solar energy generated during the day and use it when you need it most at night, during peak hours, or when external power is unavailable.
Without battery storage, excess solar energy is sent outward, while your home relies on external power at night, during peak hours, or when solar generation is unavailable.

Jack was easy to deal with since I had installed my solar panels through him two years ago he knew me straight away and was ready to give a good deal on my battery package

Highly recommend this team for anyone looking at solar storage! Sun Select is a real supplier!! will not hesitate to contact them again if any other need arise.
Shane the service sales team was very truthful, polite & reliable. Amazing customer service even after the sale. Alex installer made a mess & left some of his mess, he was not professional, he also left the inverter off so we missed out on a week of consumption we the customer had to figure how to turn it on ourselves, he also left & didn’t wait till it responded to check every thing properly, installer was not good but sun select have been amazing.
Communication was consistently diligent and respectful, which was much appreciated. The entire process advanced smoothly without any complications. The Installation team (Archi and John) worked efficiently and offered clear, detailed explanations. I would also like to express my sincere gratitude to Wilson for his comprehensive support.
Great service and always communicating until battery get installed. Thanks Shane for all your support and great service. Battery get installed within a week.
