Questions
Can the Westinghouse iGen4500DFc run Panasonic NN-SU656WAWH microwave, electrical input?
Runs. Running draw 1,500 W fits within 3,700 running watts and this is not a motor-start load.
What watts were compared?
Generator: 3,700 running W and 4,500 starting W on gasoline. Appliance: 1,500 W running, startup not published.
How long will it run?
Fuel runtime depends on total load. Published runtime: 18 hr at 25% load on gasoline, 22 hr at 25% on propane.
Where did the numbers come from?
Westinghouse spec sheet and manual: gas 4500 peak / 3700 running; propane 4050 / 3330; 5-20R duplex, TT-30R, 2 USB; 3.4 gal; 18 hr gas / 22 hr propane at 25%; 52 dBA; 105.8 lb dry; CO sensor. Panasonic lists power supply 120 V / 60 Hz, microwave output 1,100 W, and microwave power consumption 1,500 W. The station has to supply the 1,500 W input, not the 1,100 W cooking output. A separate startup surge is not published. X-Boost and Power Lifting are not applied, because those modes are described for simple heating loads and a microwave is an electronic supply.
Safety first
- Run a generator outdoors only, at least 20 feet from the house, with the exhaust pointed away from doors, windows and vents. Never in a garage, basement, shed or crawlspace, even with the door open.
- Carbon monoxide is odorless and can kill in minutes. Keep battery CO alarms working inside the home.
- Never backfeed a house by plugging a generator into a wall outlet or dryer receptacle. It can energize utility lines and kill a lineworker or a neighbor.
- Connecting to home wiring requires a transfer switch or a listed breaker interlock with a power inlet box, installed by a licensed electrician and permitted where your jurisdiction requires it.
