Must Energy Technology PH11-5KL3-EU

CEC listing: PH11-5KL3-EU (AS4777-2 2020)

A 5 kW three-phase hybrid inverter that is battery-ready.

Installed in Perth, typical: ~$2,375; Estimate for the inverter alone — your quote will vary
Rated power: 5kW; How much solar it can run at once
Battery-ready: Yes; Hybrid: a battery plugs straight in, no second box

What we can tell you

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

It is a hybrid inverter: solar and a battery run from the one unit, so adding a battery later doesn't need a second box.
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: 5kW
Max efficiency How much of the solar you make reaches the house: 97.6%
Phases Needs a three-phase supply — check your switchboard: 3-phase
Type Runs solar and a battery from one unit: Hybrid
Warranty How long Must Energy (Guangdong) Technology Co Ltd stands behind it: 5yr

5-year inverter warranty

Must Energy Technology PH11-5KL3-EU

This inverter comes with a 5-year warranty covering defects from accredited installations. Coverage is void if modified or tampered with.

AI-summarised from the manufacturer warranty document. Always confirm against the linked PDF before relying on it for a claim.

Coverage shape: Full-replacement coverage
If you sell the home: Does not transfer with the home
What voids it: Non-accredited installation, modification, or tampering voids the warranty.
Environment limits: Operating temperature range of -25°C to +60°C; derating above 45°C.
