Get these in writing

☐ Warranty length and throughput limit (MWh), whichever comes first
☐ Guaranteed capacity at the end of the warranty (for example, 60–70%)
☐ Inverter warranty, which is often shorter than the battery's
☐ Workmanship warranty from the installer, including how long it lasts
☐ Who to contact for claims, and the steps if the installer has closed
☐ Monitoring: do you own the account and keep access if you change providers?
☐ VPP terms (if any): exit fees, how much of the battery's cycling they control, and any effect on the warranty

The Australian Consumer Law guarantees apply on top of any warranty. They can't be excluded, and the seller must provide a remedy (ACCC).
