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.

Great service and always communicating until battery get installed. Thanks Shane for all your support and great service. Battery get installed within a week.
It has been great honor for being served by Jack. Jack has provided competitive offer among all the battery installers at the beginning, then he guided me on my meter board upgrade for compliance requirements, and secured a timely installation date and great installer-Kiran. The 42kwh Fox ESS battery and 9.9kw hybrid inverter work so well with a three hour free power plan, the power bill is not reduced to zero.
Great service, excellent communication. I bought a 42kWh Foxess battery with 10kW inverter, went with Sunselect because they were one of the few installers with capacity pre-May. Pricing was also very competitive, with partial backup included. Ended up being installed mid-March. Delivered on their promises, including refunding part of the cable costs when the required cable run was shorter than the original quote.
I have just had a 40kw battery system installed by SunSelect. I first contacted them in early March and the whole process from start to finish has been excellent. My main contact was Shane and he has been fantastic but the whole team and the process has been seamless
Very Professional personals. Detailed information on installation and step by step updates.
