Identify the complete generator first
Record the generator-set manufacturer or packager, set model, serial number and electrical rating. Then record the engine manufacturer and engine model separately. Photograph both identification plates. A brand on the engine alone may not identify the assembled generator.
Show condition with evidence
Share operating hours, maintenance records and any available load-bank report. Include the test date and results. Disclose leaks, alarms, missing parts and repairs needed. If you have not verified that the unit runs, say so; a clear unknown is more useful than an unsupported claim.
Make the sale scope explicit
List what is included: enclosure, base tank, trailer, batteries, automatic transfer switch, cables or other accessories. Identify anything pictured that will not be sold. Avoid having a buyer price a package that changes later.
Explain removal before requesting bids
Provide the equipment ZIP code, installation status and whether decommissioning is needed. Say who arranges disconnection, lifting and loading. Describe narrow access, rooftop placement, truck restrictions and pickup dates. These details help buyers price the whole job instead of discovering extra work during collection.
Compare what you keep, not just the headline bid
Ask what each offer includes and which conditions can change the amount. Compare seller fees, removal or freight costs you must pay, inspection conditions, payment timing and offer expiry. For example, an illustrative $30,000 bid with $5,000 of seller-paid removal leaves $25,000 before other costs; a $28,000 bid including removal may leave more.
Spend on preparation deliberately
Organize records, take clear photos and safely remove loose clutter around the unit. Before paying for repairs, repainting or a new test, ask whether buyers need that work and whether it is likely to change their offers. Do not hide defects or operate equipment just to create a more impressive listing.
