The brains of a grid-connected solar system — battery-ready hybrids for self-consumption and backup, or grid-tied string inverters when the budget can't stretch to a battery today.
The inverter is the hardest-working component in your system, so the brand matters. We stick to four manufacturers we've installed for years — these are the ones with the build quality, the local service team, and the integration with the batteries we trust.
Deye is one of our default choices when a customer wants a clean all-in-one — inverter and battery in a single wall-mounted stack with no separate DC cabling. They also make a strong range of grid-tied string inverters at sharp prices. Mature Australian support, fast warranty turnaround when it's needed.

Sungrow makes Australia's most-installed string inverter and a full residential hybrid range that pairs directly with their own LFP batteries. The iSolarCloud monitoring app is one of the best in the industry, and their AU service team is rock-solid. The default when a customer just wants the reliable choice.

Fox ESS hits the price/quality sweet spot for budget-conscious builds — a full residential range of hybrids that pair with their own batteries, plus a value-priced string line. The local AU team has been quietly building a strong support reputation. The pick when we need to hit a number without compromising on warranty or monitoring.

Fronius is the Austrian-engineered reference standard. Active cooling that holds performance through 45°C Hunter summers, the strongest local service team in the industry, and a build quality you can hear when you tap the casing. Our pick for grid-tied string and for AC-coupled solar input on off-grid jobs — anywhere reliability has to come first.
