A solar inverter converts the direct current (DC) electricity produced by your panels into alternating current (AC) used by appliances and the grid. Common options include string inverters, microinverters attached to individual panels, and hybrid inverters designed to work with batteries. When comparing models, consider system size, efficiency, monitoring, warranty terms, battery compatibility and whether the inverter suits your roof’s shading conditions. A Clean Energy Council-accredited installer can help select and install a compliant system, while current Australian requirements can be checked through energy.gov.au.
