Overview

Himoinsa HS Stationary Range (7-50 kVA)
The HS series generator sets are compact, robust diesel units designed specifically for stationary emergency and standby power in commercial, industrial and residential applications. Built with high-quality materials and premium components, they feature Yanmar engines (developed exclusively for this range up to 50 kVA) that deliver reliable ESP performance.
Key features include a space-saving canopy with multiple access doors and removable panels for quick maintenance, an AC5 digital control panel with optional integrated automatic transfer switch (ATS), and dual cable entry points for simplified installation. External IP55-rated ATS options are available.
Main benefits:

Fast, low-cost maintenance that minimises downtime and operating costs.
Easy grid connection thanks to the built-in ATS version.
High reliability with competitive power output tailored for stationary use.
Straightforward installation and user-friendly operation in a compact design.

Ideal for supermarkets, hospitals, banks, small-to-medium industry, agriculture, water treatment and residential backup, the 7-50 kVA HS range provides dependable power with durability, accessibility and cost-effective performance for fixed installations.
