Solar battery & EV
Keep the energy you already paid for
Battery storage turns a good solar system into an energy independent one. Solargain sizes, installs and commissions batteries and EV chargers as one integrated system.
Tesla Powerwall 3 and more
Solargain is an authorised installer of leading battery brands, including Tesla Powerwall 3 with its integrated solar inverter. Whether you're adding storage to an existing array or building a new hybrid system, we specify the battery around your actual evening load — not a brochure figure.
- Retrofit to most existing solar systems
- Backup circuits for essential loads
- State battery rebates and loans handled for you
- App monitoring for solar, battery and grid flows

How battery storage works
01
Your panels produce
Through the middle of the day your array generates more than the house is using.
02
The battery charges
Surplus energy is stored instead of being exported for a small feed-in tariff.
03
Evening peak covered
The battery discharges through the expensive evening period when the family is home.
04
Blackout backup
With backup circuits wired in, essential loads keep running when the grid goes down.

EV chargers
A home charger fed by your own solar is the cheapest fuel in the country. Solargain installs smart 7 kW and 22 kW chargers with scheduling, solar-only charging modes and dynamic load balancing so your main supply never gets overloaded.
Dynamic load balancing measures what the rest of the house is drawing and adjusts the charge rate in real time — no switchboard upgrade needed in most homes.
