From May 1, 2026, all new battery installations in WA require CSIP-AUS compliant inverters. Verify ESM status with your installer.
Perth's high ambient temperatures (regularly 35°C+) can reduce inverter efficiency and trigger thermal throttling. For installations in direct sun or non-ventilated garages, consider inverters with active cooling and wide operating temperature ranges. All grid-connected installations require Western Power approval. Systems above 5kVA require ESM compliance under WA regulations.
