• Tier 4 Final compliance: Runs on job sites and in jurisdictions with strict emissions rules without aftermarket retrofits.
• Trailer-mounted mobility: Tow to site, level, connect, run. No crane, no pad.
• Sound attenuation: Quiet enough for events, hospitals, and residential-adjacent construction.
• Fleet consistency: Multiple identical units means matched spares, interchangeable parts, and simple paralleling for larger loads.
• Generator Source support: Every unit is inspected and load-tested by our EGSA-certified technicians before it leaves the yard, and our service team covers PM and repair after delivery.

Can I rent a unit first and buy it later?

Yes. Ask about rent-to-own terms when you request a quote. A portion of rental payments can be applied toward purchase.

Why do some units not show a list price?

Those units are priced on request. Submit the form with the unit number and you will get a firm sale price and rental rate.

Can multiple units be paralleled?

Yes. Identical G125RS units can be paralleled to cover loads above 100 kW. Tell us your load profile and we will size the package.

Do you deliver?

Yes. Delivery is available nationwide from our Colorado, Texas, and Florida locations. Rental delivery and pickup are quoted with the rental rate.

What comes with a purchased unit?

Inspection report, load test results, hour meter reading, and service history. Optional extended warranty and PM contracts are available through Generator Source Service.
