Central to your solar PV system, a solar inverter is responsible for turning the DC power your solar panels produce, into the AC power your home and appliances run on.
Where most faults in a solar PV system occur, it’s important to choose a good quality inverter that will last at least 15 years, to ensure you get a good return on your initial investment. While it may be tempting to purchase a cheaper inverter in the beginning, the cost of replacing it further down the line will negate any original savings.
We’ve compiled a list of the top 5 inverters found in Australia, based on warranties, manufacturing processes, and monitoring features, that we’d be happy to recommend to friends and family, or install in our own homes.
