One of the cheapest battery packages, but how?

Typically, a solar battery installation is similar to getting a builder to quote on a kitchen renovation – each quote varies widely in quality and price. Think of the DC Sunny Saver like a flatpack kitchen, instead of bespoke cabinetry designed and built from scratch. Installed from just $1595.

Extended warranty

A 10-year manufacturer’s warranty for your battery and 12 years on your inverter. That’s an extra 7-years warranty on the hybrid inverter compared to the standard 5 years!

Free delivery

Delivery straight to your door! Included within the ticket price, so you don’t have to worry about additional delivery costs.

Installed from just $1595
