Hoymiles HMS-1800C-4T

CEC listing: HMS-1800C-4T (AS4777-2 2020)

A 1.8 kW single-phase solar inverter.

Installed in Perth, typical: ~$540; Estimate for the inverter alone — your quote will vary
Rated power: 1.8kW; How much solar it can run at once
Battery-ready: No; Solar-only: adding a battery later means a second inverter

Is it right for your home? — Hoymiles HMS-1800C-4T

Hoymiles HMS microinverters are the main lower-cost alternative to Enphase in Australia. They deliver per-panel power conversion at pricing below Enphase IQ8, and have built up installer uptake on that price point. For Perth installs, Hoymiles HMS provides microinverter benefits such as per-panel optimisation and better partial-shade handling, at more accessible pricing than Enphase IQ8.

Where it wins

Lower-cost microinverter option
Per-panel optimisation
Better partial-shade handling than a string inverter
Growing installer adoption

Where it falls short

Less mature ecosystem than Enphase
12-year warranty (Enphase IQ8 is 25 years)
Monitoring platform less polished

Best for

Microinverter installs on a tighter budget
Shaded roofs on a budget
