My "B" has a 1000w Triplite invertor in it coming off of the a size 30 battery. I estimate that the no load draw of the inertor is approx. 10w (per hour). That is if I leave the invertor turned on with no load for 24 hours it appears to drain about 240 watts out of my house battery. In your experience is this high or low???? :-\. I also know through the school of hard knocks that if I have the invertor turned "off" that it still draws 1-2 watts :-\ :-\ :-\. The only ways to really prevent battery drain for extented periods by the invertor is to disconnect the battery. Again is this slight drain considered nornal for an invertor???
