Stack your storage. Stack your savings.
Every additional Sigenergy battery module you add knocks $1,000 off your price — up to a maximum saving of $5,000. Bigger storage, lower bills, a bigger discount.
Get the full value out of your solar
Without storage, most of your solar is exported to the grid for cents. A battery keeps that energy for when you actually use it.
Store your solar
Bank the excess energy your panels make during the day instead of selling it back for next to nothing.
Power day & night
Run your home on your own clean energy after sunset, instead of buying expensive power from the grid.
Blackout backup
Keep your fridge, lights and Wi-Fi running when the grid goes down. Your home stays on, automatically.
Cut your bills
Shield yourself from rising electricity prices and watch your quarterly bills shrink — often to almost nothing.
Energy independence
Take control of how and when you use power, all managed intelligently from one simple app.
Melbourne's Sigenergy specialists
A local team that designs, installs and supports your system end to end — no subcontractors, no sales gimmicks.
Sigenergy installed across Melbourne
Genuine installations by our local E³ Energy team — clean, considered and built to last.
Real homes. Real savings.
Our power bill went from nearly $500 a quarter to almost nothing. The E³ team were professional from the first quote right through to switch-on.
Clean, tidy install and the app makes it so easy to see exactly what we’re saving. Adding the second battery for $1,000 was a no-brainer.
We got three quotes — E³ were the only ones who actually explained how to get the most out of Sigenergy. We had a blackout last month and didn’t even notice.
