Knew someone would ask. Running a 1200W food warmer for an hour, until i can hook it up to the engine heat/cool system. Might not need 1000W, but at least 700W to 800W. Might be easier just to hook up a bank of batteries. ======================================================== Will you be stationary? I guess I was assuming that before, from your idling questions. If so, just get one of those $89 on sale harbor freight 700 watt generators if that would be just enough, or the 4000 watt one for about $300. If you are driving around but it is a temporary fix until you plumb into the heater loop for hot water, then just use the 1000W inverter and don't worry about idling unless you spend a lot of time doing it. It may not be optimal but it will get you up and running for now. The battery will go down a bit at idle but will charge back up when you start moving again. Get one of those $10-15 ebay voltmeters that plug into the cigarette lighter if you want to keep an eye on the system voltage while the engine is running and the battery voltage with engine off, there's even a cute one with two usb ports for phone charging. (If the inverter draws 80A and the alt can source 50A at idle that is a battery draw of 30A so the battery will last about three times longer idling than with engine off and my guess is that on just battery it could last 40-50 minutes completely discharging the battery, so my swag is that you could idle for 20 minutes at a time without discharging the battery too deeply before you need to rev the engine back up. Brief stops as an ice cream truck ok, parking for two hours as a roach coach not so much :-).) -- Regards, Carl Ijames
