The company organizes its portfolio into four application segments: On-Site Power (HI Industrial Range up to 2617 kVA diesel/1183 kVA gas; HS Stationary Range up to 420 kVA), Mobile Power (HR Rental Range, HC Compact, EHR Battery, and lighting towers including the HBOX+ hybrid), Telecom Power (HT Range up to 42 kVA), and Power Solutions (HP Special, MV Medium Voltage up to 2536 kVA, DC Data Center). Supporting products include CC2 automatic transfer switch panels and mobile transformer substations. Digital offerings comprise the CE8 family of controllers, the Generator Finder tool, the My Product customer portal, the Product Suite software, and a Spare Parts 24/7 service. Customer segments span data centers, construction, mining, telecom, healthcare, water treatment, events, and general critical power applications.

Himoinsa operates a quote-based B2B sales model with no public pricing, multi-year contract cadence, and revenue derived primarily from equipment sales (one-time license) supplemented by aftersales service and spare parts. In August 2025 the company acquired Powersil to vertically integrate electric control panel manufacturing. Brand identity is maintained as 'HIMOINSA a Yanmar Company.'
