Compare inverter type, usable capacity, efficiency, warranty, monitoring features and compatibility with your panels and any future battery. String inverters are often simpler and more cost-effective, while microinverters can suit roofs with shading or multiple orientations; hybrid inverters are designed to work with batteries. Check whether warranty servicing is available in Australia and whether an accredited installer can support the product. Product performance and suitability depend on your system design, so ask a licensed installer for advice and compare the manufacturer’s current specifications.
