Battery installation is skilled, safety-sensitive electrical work. The unit must meet your region’s placement rules (clearances, ventilation, mounting) and be installed by a licensed professional. Never DIY.

Indoor vs outdoor placement

  • Many batteries are weather-rated for outdoor (garage wall, exterior)
  • Indoor units need clearances and ventilation per spec
  • Avoid plunge areas and direct rain/sun unless rated
  • Check fire-code setback from windows, doors, vents

What installation involves

  1. Site assessment and load/circuit evaluation
  2. Mounting and battery connection
  3. Integration with inverter/switchboard and monitoring
  4. Compliance testing and network approval
  5. Commissioning and handover walkthrough
How long does battery installation take?
Typically a few hours to a day for a straightforward AC-coupled or hybrid install, plus approvals that can add days to weeks.
