A used generator or inverter is worth buying only when it has been run under load in front of you, not merely started.

Ask what batteries are included, and their age, before delivery is arranged.

What to check before buying a used generators, ups & solar
These are the checks that set the condition grade on anything we list — and the ones worth running yourself wherever you buy.
Start it from cold
Ask that the generator has not been run that morning. A healthy engine catches within a few pulls, or on the first turn of the key, and settles to a steady note. Long cranking, a haze of unburnt petrol or blue smoke that will not clear after a minute points at worn rings or a carburettor that has been standing.
Run it under load
No-load running proves very little. Plug in something substantial, an iron or a heater, and listen. The engine should take the load with a brief dip and then hold. Lights that dim and brighten, or an engine hunting up and down, suggest a tired governor or a failing AVR.
Check the oil and smoke
Pull the dipstick before anything is started. Oil that is milky, thin or smells of petrol tells you more than any test run. Under load, black smoke is a fuelling problem and blue smoke is oil getting past the rings, and both are easier to spot before the engine is warm enough to hide them.
Inspect the battery bank
On a UPS or solar setup the batteries carry much of the value. Look for the manufacture date on the case, bulging sides, powdery corrosion at the terminals and low electrolyte in a tubular cell. A bank that charges full and then runs a couple of fans for minutes rather than hours is finished.
Watch the changeover
Switch off the main breaker with a fan and a light running. A sound inverter takes over without the fan stopping and without loud relay chatter. Note also whether it is a pure sine wave unit or a modified wave one, which makes fans and motors buzz and is wanted less.
Hold panels to the light
Look across a panel face at an angle. Cracked glass, hairline crazing across the cells, brown snail trails and bubbling of the plastic back sheet all mean output that will not come back. Check the junction box cover is sealed and the MC4 leads are not perished, and read the rating plate rather than trusting a quoted figure.
