SolaX Power X3-PRO-17K-G2

CEC listing: X3-PRO-17K-G2 (AS4777-2 2020)

A 17 kW three-phase solar inverter.

Installed in Perth, typical: ~$4,590; 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.
We hold no captured datasheet for this model yet, so the specs below come from the CEC register only.
