Inverter Replacement

Inverters die at 8 to 12 years. Most Adelaide solar is now in the replacement window.

If your solar was installed before 2018, your inverter is likely approaching end of life. Replacing it with a modern hybrid inverter (Fronius GEN24, Sungrow SH, GoodWe ET) prepares your system for battery storage without re-wiring the panels.

$1,800 - $4,500 depending on inverter type (string vs hybrid) and system size

The honest overview

A string inverter is the single most failure-prone component of a solar system. Most rooftop inverters in Adelaide reach end of life between 8 and 12 years. When yours fails, the replacement decision is whether to install a like-for-like string inverter ($1,800 - $2,800 installed) or step up to a hybrid inverter ($2,500 - $4,500 installed) that supports a battery if you add one later.

Inverter Replacement: questions

Can I keep my old solar panels?

Yes - most quality panels last 20-25 years. Replacing only the inverter while keeping the panels is a cost-effective upgrade.

Do I have to upgrade to a hybrid inverter?

No - a like-for-like string inverter replacement is cheaper. Upgrade to hybrid only if you are likely to add a battery within 5 years.

Does replacing the inverter affect my STC rebate?

No - the STC rebate was claimed at the original install. Inverter replacement is paid out-of-pocket. The new inverter does carry its own manufacturer warranty.
