Description
⚠ Professional installation product — installation should only be carried out by qualified solar PV installers in accordance with local electrical regulations and system design requirements.

The Hoymiles HMS-1800-4T microinverter is a powerful four-input module-level inverter designed for professional residential and small commercial solar PV installations.

Delivering up to 1800VA AC output with independent MPPT tracking across four solar modules, the HMS-1800-4T is engineered for larger rooftop arrays where improved module-level optimisation, system flexibility and higher energy yield are required.

Built with an IP67 outdoor-rated enclosure and passive cooling architecture, the HMS series is designed for long-term reliability and consistent performance in demanding outdoor environments.

The HMS ecosystem is compatible with Hoymiles DTU monitoring gateways, S-Miles Cloud monitoring and Flex-S3 cabling accessories, allowing installers to create scalable and monitoring-ready PV systems.

For app access, remote monitoring and system performance visibility, a compatible Hoymiles DTU monitoring gateway is required.
