Our read of the datasheet
The IQ8HC is a microinverter: one unit mounts under each panel and converts its output to AC on the roof. Each unit is rated at 380 VA (384 VA maximum) and accepts up to 505 W of DC input, so output from high-wattage panels above that AC limit is clipped. Because each panel has its own MPPT, shade or different roof faces affect only the panels concerned.
The DC side stays at panel voltage, up to 60 V, and the datasheet lists rapid shutdown. System size is set by the number of units: up to 10 on a single-phase 20 A branch circuit, or 36 on a three-phase 25 A circuit.
Batteries are AC-coupled with the Enphase IQ Battery 5P, and the system keeps producing in a blackout only when installed with the IQ System Controller 3 INT and IQ Battery 5P. Maximum efficiency is 97.4% and European efficiency 96.8%. The 25-year limited warranty requires an internet-connected IQ Gateway.
We have not tested this inverter. This summary follows from the manufacturer's published specifications, checked 23 September 2026.
Strengths
- Panel-level MPPT, so shade or mixed roof faces affect only the panels concerned
- Low-voltage DC with rapid shutdown
- 25-year limited warranty (with internet-connected IQ Gateway)
- IP67 rating
Things to check
- Output capped at 384 VA per panel, so high-wattage panels are clipped at peak
- Backup needs IQ System Controller 3 INT and IQ Battery 5P
- Electronics sit on the roof, one unit per panel
