As more Australians turn to solar energy to power their homes, choosing the right solar battery has become just as important as selecting the right panels. Two of the leading contenders in the home energy storage space are the Tesla Powerwall and the SENEC Home V3. Both offer powerful features for storing solar energy, providing backup during blackouts, and helping reduce reliance on the grid—but they differ in a few key ways.
Isolux Solar, we’re committed to helping homeowners make informed choices about solar battery. Here’s a side-by-side comparison of the Tesla Powerwall and SENEC battery systems to help you decide which one suits your energy needs best.
