Why buyers choose Hipower

  • Full vertical integration — designs and builds enclosures, fuel tanks, switchgear, and controls in-house
  • Most engine diversity — Yanmar, Isuzu, John Deere, Volvo, FPT, PSI, MTU, and Mitsubishi options
  • US manufactured — 515,000 sq ft facility in Olathe, Kansas
  • 9 kW to 2,230 kW range — one of the broadest lineups in the industry
  • Natural gas line (HNI) — 30-1,000 kW, CARB certified

Who Hipower is for

Cost-conscious data centers and hospitals needing Big 4 specs at Tier 2 prices, rental fleets (HRVW mobile line), and California natural gas projects.

What to consider before specifying Hipower

  • Brand recognition gap outside the rental/contractor market
  • Thin dealer network — Leddy Power in California
  • No organic buyer community or specification history
  • Weaker resale value versus Big 4 brands

Hipower Systems occupies a unique position in the generator market: genuine data center-grade engineering backed by Yanmar/Himoinsa's global manufacturing scale, at pricing 15-25% below the Big 4 brands. The key differentiator is vertical integration — where most manufacturers source enclosures, fuel tanks, switchgear, and controls from third-party suppliers, Hipower designs and builds all of these at their 515,000 sq ft facility in Olathe, Kansas. That manufacturing depth, combined with access to eight engine OEMs (Yanmar, Isuzu, John Deere, Volvo, FPT, PSI, MTU, and Mitsubishi), gives specifiers more flexibility in matching the right engine platform to the application.

The trade-offs are real. Hipower lacks the brand recognition, dealer density, and resale value of Caterpillar or Cummins. In California, Leddy Power Systems is the primary dealer — compared to the dozens of authorized service points that CAT and Kohler maintain in the state. For mission-critical applications where parts availability measured in hours (not days) is non-negotiable, the Big 4's deeper service networks still win. But for cost-conscious buyers who need NFPA 110 Level 1 certification, seismic ratings, and 200 mph wind-rated enclosures without paying a premium brand surcharge, Hipower delivers specs that match or exceed the competition.

The natural gas lineup (HNI, HGM, and HNG series) is particularly compelling for California projects. CARB-certified from 30 kW through 1,000 kW, these units eliminate the diesel fuel storage permitting that adds weeks and thousands of dollars to standby generator installations in the Bay Area. For healthcare facilities, commercial buildings, and data centers where natural gas infrastructure already exists, Hipower's NG lineup offers a compliant, cost-effective path to backup power — especially when paired with the HRNG mobile series for temporary power during construction or planned maintenance events.

Frequently asked questions

Who manufactures Hipower generators?
Hipower Systems is a subsidiary of Yanmar/Himoinsa, one of the world's largest generator manufacturers. All US-market units are designed and built at Hipower's 515,000 sq ft facility in Olathe, Kansas. Unlike most competitors who source enclosures, fuel tanks, and controls from third parties, Hipower manufactures these components in-house — the same vertical integration model that Yanmar applies globally.
How does Hipower pricing compare to Caterpillar, Kohler, and Cummins?
Hipower units typically price 15-25% below comparable models from the Big 4 (CAT, Kohler/Rehlko, Cummins, Generac). The savings come from Yanmar/Himoinsa's global manufacturing scale and lower brand premium, not from cutting specs. Hipower units carry the same NFPA 110 Level 1 certification, seismic ratings, and 200 mph wind ratings as the premium brands. The trade-off is thinner dealer coverage and lower resale value.
Are Hipower natural gas generators CARB certified for California?
Yes. The HNI series (30-1,000 kW) and HGM/HNG series carry CARB certification, making them compliant for California installations. This is significant because CARB-certified natural gas generators eliminate the need for diesel fuel storage permits and meet increasingly strict Bay Area Air Quality Management District requirements. Hipower's California dealer is Leddy Power Systems.
