Panels degrade slowly and predictably. The inverter is the component doing the work, and it is generally the first thing anyone replaces — which is why the warranty, and the company standing behind it, deserve more scrutiny than they usually get on a quote.
From a small single-phase unit to a 50 kW three-phase one, they share the same architecture, the same monitoring and the same warranty. Which one lands on your wall is a function of your supply, your roof and how many orientations the array is split across.
1-3.3KTL-G3
1.0 – 3.3 kW
The small end of the range. Single tracker, one roof plane, sized for a modest array on a townhouse or a unit with roof rights.
3-6KTLM-G3
3.0 – 6.0 kW
The unit that ends up on most Australian houses. Two trackers, so an east-and-west split array does not drag the whole system down to the shadier side.
3.3-12KTLX-G3
3.3 – 12.0 kW
For larger single-phase homes and rural properties running a bigger array than a standard 5 kW unit can carry.
7-10.5KTLM-G3
7.0 – 10.5 kW
The entry point for a three-phase connection. Spreads generation evenly across the phases, which keeps your distributor happier than a large single-phase export does.
15-24KTLX-G3
15.0 – 24.0 kW
Large homes, small commercial rooftops, and properties where the array will grow again in a few years.
25-50KTLX-G3
25.0 – 50.0 kW
The top of the residential range and the bottom of the commercial one. Three trackers for a roof with several orientations, and remote management across a fleet of sites.
Approved, and therefore rebate-eligible
These inverters are listed on the Clean Energy Council approved product list, which is a precondition for a system to claim Small-scale Technology Certificates. They are certified to AS/NZS 4777.2, the standard governing how an inverter behaves when it is connected to the Australian grid. If a quote cannot show you both, that is worth asking about before you sign it.

The warranty is backed by SOFARSOLAR, a publicly listed manufacturer with audited accounts, rather than by a reseller whose ABN is younger than the product. Claims are handled here, on local hours, by people who can read a fault code.
We aim to authorise inside 24 hours and dispatch from stock held in warehouses across the mainland states.
Open a trade account and the first unit is on us. Commission it, break it, put it through whatever you put a new brand through, and then decide whether you want to defend the choice in a customer’s kitchen.
