Every home and business is different. The ideal system size heavily depends on your specific daily energy consumption and peak demand. While a standard household might need a 10kWh+ battery just to get through the night, your goals might be bigger. For example, if you want to join a Virtual Power Plant (VPP) — a connected network of home batteries that allows you to sell your stored energy back to the grid at premium rates during high demand—we highly recommend a larger battery setup ranging from 14kWh to 48kWh. At E³ Energy, we analyse your electricity bills to custom-design a system that perfectly matches your lifestyle and financial goals.

There are fantastic incentives available, but they are changing soon:

Solar Panels: Eligible Victorians can claim a State rebate of up to $1,400 for solar PV installation, along with an option for a matching interest-free loan through Solar Victoria.
Home Batteries: Victorian households can access the Federal Cheaper Home Batteries Program for a massive upfront discount. However, on May 1, 2026, this federal rebate is scheduled to drop significantly and will introduce strict capacity tiers. It is critical to act quickly to lock in your maximum savings before the May deadline. We handle all the complex rebate paperwork for you!

Yes, but it requires the right setup! Standard solar-only systems automatically shut down during a grid outage to protect line workers. However, by installing a premium battery system with backup capabilities, your home can automatically switch to stored battery power during a blackout. This keeps your essential circuits—like the fridge, lights, and Wi-Fi—running smoothly while the rest of the street is in the dark.
