What to look for
Load assessment. A good supplier asks for your appliance list and daily kWh use before quoting. Be wary of any price given without one.
Battery chemistry and capacity. Lithium iron phosphate is now common. Check usable capacity, not just the nameplate figure, and ask about warranty cycles.
Inverter sizing. It must handle your peak surge loads, such as pumps and power tools.
Generator integration. Perth winters can have several cloudy days in a row, so ask how backup starts automatically.
Credentials. Look for a licensed electrician and Clean Energy Council accredited installers, plus a clear warranty and service plan.
