  • Tesla Powerwall 3, AlphaESS, Sungrow & more
  • Retrofit to most existing solar systems
  • Self-consumption up to 80%+

Batteries store surplus solar instead of exporting at low feed-in rates — then discharge during evening peak when power costs most.

We size to your usage profile and backup goals before recommending Tesla Powerwall, AlphaESS, or other approved units.

Solar Battery

Why Solar batteries are important?

Store daytime solar. Use it after sunset or when the grid drops.

How Does it Work?

  • Panels generate power during the day
  • Surplus charges the battery instead of exporting cheap
  • Battery discharges at night or during cloudy periods
  • Use stored energy through the day as your load changes

Good to know

How storage works

Solar charges the battery by day. Your home draws from the battery first at night, then the grid when empty.

Retrofit or new install

Most grid-connected homes can add a battery later. We confirm inverter compatibility before quoting.
