MasPower 22.5kW Mobile Yanmar Diesel Generator | MP22D-S

This MasPower mobile diesel generator combines a dependable Yanmar engine, a weatherproof sound-attenuated enclosure, a 100-gallon fuel tank, and a single-axle trailer in one emergency-ready package. It is built for buyers who need serious backup power that can be moved to the location where it is needed, then secured with the trailer's pad-mount tie-down points.

Emergency standby use only. Call us for Prime or other options: Before purchase is completed, the buyer must provide a statement confirming that this generator will be used for standby service and moved only for emergency purposes. This is not being represented as a continuous-duty prime-power unit.

MasPower 22.5kW Mobile Yanmar Generator

The name says 22.5kW, but the controlling MasPower specification sheet rates this package at 22,000 watts standby output. That is the number we use when sizing loads. At 120/240V single-phase, it is a practical option for emergency backup at commercial buildings, farms, municipal facilities, service operations, and remote properties where a stationary generator is not the best fit.

What stands out here is that it is already set up as a real mobile package. The generator is mounted on a single-axle trailer, the enclosure is built for outdoor service, and the large fuel tank supports extended runtime. The unit is full-load test run and delivered with fluids filled, so the preparation work has already been handled before shipment.

Why This Mobile Diesel Generator Makes Sense

• Yanmar diesel power: Liquid-cooled 4TNV84T engine operating at a low 1,800 RPM.
• 22,000-watt standby rating: 120/240V, single phase, 60 Hz output rated at 92 amps at 240V.
• Extended fuel capacity: Integrated 100-gallon diesel tank with a published 100-hour runtime at 50% load.
• Mobile emergency deployment: Single-axle trailer makes it easier to reposition the generator between prepared sites.
• Outdoor-ready enclosure: Hurricane-rated, weatherproof, sound-reducing powder-coated aluminum housing.
• Automatic-start capability: Deep Sea 6110 controller with auto start and safety shutdown functions.
• Prepared before delivery: Full-load test run completed and operating fluids filled.
• Flexible placement: Trailer includes tie-down provisions for pad mounting where permitted.

Best Uses

• Emergency backup for small commercial buildings and workshops
• Storm and hurricane response power
• Agricultural buildings, pumps, refrigeration, and farm operations
• Municipal, utility, and disaster-response staging
• Remote properties that need movable standby power
• Temporary emergency backup while a permanent generator is being serviced

Every site is different. Motors, pumps, air conditioners, refrigeration equipment, and other loads can draw substantially more power during startup. Have a licensed electrician or generator professional complete a load calculation before ordering.

Frequently Asked Questions

Is this a 22kW or 22.5kW generator?

This mobile package is commonly identified as a 22.5kW unit. The MasPower brochure's controlling 22 kW column lists a rated standby output of 22,000 watts, so load planning should be based on 22 kW.

How long will the 100-gallon tank run?

MasPower publishes fuel consumption of 1 gallon per hour and approximately 100 hours of runtime at 50% load. Actual runtime changes with electrical load, ambient conditions, maintenance, fuel quality, and operating conditions.

Can it power an entire building?

Possibly, but the answer depends on the building's actual load and the starting requirements of motors, HVAC equipment, pumps, and compressors. The generator is rated for 92 amps at 240V. A professional load calculation is required before installation.

Can this generator be used as prime power?

No. This package is offered for emergency standby use. A buyer statement confirming standby-only use and emergency movement is required before the sale is completed.

Can the trailer-mounted unit be secured to a pad?

The trailer includes tie-down points intended to support pad mounting. Final mounting, anchoring, electrical work, fuel compliance, permits, and site approval must be completed according to local requirements.

Does it support automatic starting?

Yes. The Deep Sea 6110 control panel provides auto-start functionality and protective shutdowns. A properly designed transfer and control system may be required for your site.

Is a transfer switch included?

No transfer switch is listed as standard equipment. Contact AllProGenerators before ordering so we can help identify the right connection and switching solution for the intended application.
