This is a mode designed to desulfate your RV's batteries and prevent material build on the battery plates. This mode will typically last for an hour or so and then return to the normal float voltage.<BR/><BR/>You can read more about smart chargers here: http://www.modmyrv.com/2008/06/08/rv-battery-charger/Name: Mark Corganhttp://www.blogger.com/profile/03019642291679093884noreply@blogger.comtag:blogger.com,1999:blog-4413319760292273475.post-14303598563444426482008-11-25T01:57:00.000-08:002008-11-25T01:57:00.000-08:00In other countries the converter has a primordial function: convert the input voltage (110/220V) to 12/110 or 12/220V. In Brazil there are areas where the input voltage is 110 and other areas is 220V. Also there are factories that produce RVs with internal voltage 110 and others with 220V regardsAdautohttp://www.blogger.com/profile/05797513060096767285noreply@blogger.comtag:blogger.com,1999:blog-4413319760292273475.post-27256627863318107522008-11-24T08:50:00.000-08:002008-11-24T08:50:00.000-08:00After three years we found out we had a converter in our Horizon Diesel Pusher. In talking with the manufacturer I was told to turn off the switch outside by the power system and leave it off all the time. Our system has a three stage charging system for the house batteries. When plugged into shore power it always charges the batteries. The inside switch should only be turned on when you wish to run something on 120. If it is left on all of the time anything drawing 120 volts will run down the batteries. So we leave all switches off except when I want to make a cup of coffee early or we want to watch TV late in a National Park and do not or should not run our generator. We get several hours of TV without a gen by doing thisJames Blakehttp://www.blogger.com/profile/11801985644524933010noreply@blogger.com
