Sofar SOFAR 17KTLX-G3

CEC listing: SOFAR 17KTLX-G3 (AS4777-2 2020)

A 17 kW three-phase solar inverter.

Installed in Perth, typical: ~$5,100; Estimate for the inverter alone — your quote will vary
Rated power: 17kW; How much solar it can run at once — a large roof
Battery-ready: No; Solar-only: adding a battery later means a second inverter

What we can tell you

Read from the figures on this page. No review written yet.

It is a solar-only inverter: adding a battery later means a second inverter or an AC-coupled battery.
It needs a three-phase supply — check your switchboard, or ask your installer.
We can't confirm it is on Synergy's approved list — a battery paired with it needs that for the WA Battery Scheme, so ask your installer.
It is CEC-approved, which a new install needs to qualify for STCs.

Key specs, in plain terms

The numbers that matter for a home. The full datasheet is below.

Rated power How much solar it can turn into usable power at once: 17kW
Max efficiency How much of the solar you make reaches the house: 98.6%
Phases Needs a three-phase supply — check your switchboard: 3-phase
Type Runs solar only: Solar
Warranty How long Shenzhen SOFARSOLAR Co Ltd stands behind it: 10yr
