Overview#
The Airman EBOSS 125-65 is a diesel-battery hybrid energy system combining a 125 kVA Airman generator with 65 kWh of Lithium Titanate Oxide (LTO) battery storage. The mid-range EBOSS unit serves larger construction sites and events where fuel savings and noise reduction are critical. At 100 kW prime / 110 kW standby, the EBOSS 125-65 delivers building-scale temporary power capacity with the fuel and noise advantages that define the EBOSS platform. Automatic power management between diesel and battery optimizes fuel efficiency and reduces emissions.
Features unlimited parallel capability. LTO battery chemistry for superior cycle life. Built by Hokuetsu Industries in Japan with 110% fluid containment.
EBOSS Hybrid Technology at 125 kVA#
The EBOSS 125-65 brings hybrid technology to the 100 kW class — the threshold where most building-scale temporary power needs are met. The Isuzu BR-4HK1X diesel engine provides the same proven platform used in Airman's conventional SDG125, paired with a 65 kWh LTO battery bank. At this capacity, the EBOSS system can run full building loads (HVAC, elevators, lighting) on battery power alone during off-peak hours, with the diesel engine cycling on during higher-demand periods. The intelligent power management continuously optimizes the balance between battery state-of-charge, site load demand, and diesel engine efficiency. Multiple EBOSS 125-65 units can be paralleled without limit for sites requiring capacity beyond 100 kW, and the system scales linearly — two units deliver 200 kW of hybrid capacity with the same fuel-saving behavior.
Our Service Experience#
The EBOSS 125-65 is the sweet spot in the hybrid lineup for our Northern California commercial construction projects. At 100 kW prime, it covers the same building-scale loads as our conventional SDG125 fleet — hospital renovation phases, office building temporary power, and data center commissioning — but with dramatically lower fuel consumption and the ability to operate silently during noise-restricted hours. We have deployed it on projects in downtown San Francisco where nighttime noise ordinances would otherwise shut down generator-dependent work.
The diesel engine components follow the standard 250-hour oil change schedule using the same Isuzu BR-4HK1X platform as the conventional SDG125. The LTO battery system has proven low-maintenance in our fleet, requiring only periodic visual inspection. The most significant operational benefit we have observed is that the diesel engine accumulates approximately 40-60% fewer operating hours per calendar day compared to a conventional generator serving the same load profile, which translates to longer intervals between service visits, reduced fuel logistics, and lower total cost of ownership over the rental period.
