Questions

Can the Champion 4500W Dual Fuel Inverter (200988) run Amana AMND501BW dehumidifier, about 50 pints/day?

Runs. Running draw 485 W fits within 3,500 running watts. Startup watts were not published; 4,500 starting watts is at least 3× the running draw, the common planning allowance for a compressor or pump start.

What watts were compared?

Generator: 3,500 running W and 4,500 starting W on gasoline. Appliance: 485 W running, startup not published.

How long will it run?

Fuel runtime depends on total load. Published runtime: 14 hr at 1/4 load on gasoline, 21 hr on a 20-lb propane tank.

Where did the numbers come from?

Champion spec table: gasoline 4500 starting / 3500 running; propane 4500 / 3150; TT-30R, 5-20R duplex, 12V DC; 2.25 gal; 14 hr gas / 21 hr propane at 1/4 load; 61 dBA. ENERGY STAR lists 49.43 pints/day, integrated energy factor 2.01 L/kWh, and 520 kWh/year. Operating draw at the rated test condition is (49.43 × 0.473176 L/pint ÷ 24 h) ÷ 2.01 L/kWh × 1,000 = 485 W. That is the draw while it is removing water at the rated rate, not a whole-year average. Startup watts are not published.
