Compare inverters by efficiency, warranty, monitoring features, maximum power output and compatibility with your panels, battery and switchboard. String inverters are often simpler and more cost-effective, while microinverters can suit roofs with shading or multiple orientations, although they may cost more. Check whether the inverter is listed on the Clean Energy Council’s approved product list and whether local support is available. A licensed solar installer can assess your roof, electricity use and future battery plans before recommending suitable options.
