Inverter use

I have a 2008 Roadtrek 190. From your experience does the inverter need to be turned on or off when hooked up to shore power in order to charge the coach battery. I honestly didn't realize that the inverter is actually a charger as well. Up until now as per the instructions received from the dealer, I have always made sure the inverter was off when hooked up to shore power.
Thanks very much !

  • Thank you both for your replies. My inverter/charger is a Tripp-Lite RV750ULHW and is buried without easy access. The on/off switch is located beside the monitor panel which does display the charge level of the coach battery. I do get full power in all outlets when using shore power with the inverter in the OFF position. Ardum Snowbird, I think my unit is the same as the one you describe, so thank you again for clarifying that the switch is actually a remote and the OFF position is correct for charging when hooked up to shore power.
  • You should not need to have the inverter switched on to watch TV when plugged into shore power. 2005 is the year that Roadtrek began to make the switch from a separate inverter unit and charger/converter unit to the Tripp-Lite single unit that does all three functions. If you have the Tripp-Lite then you certainly should not need to have the inverter wall switch on when plugged into shore power to have power in the outlet that shares the inverter. If you have the two separate units, then this design may have been different and then the inverter may need to be on to keep power to that outlet. My Roadtrek with the Tripp-Lite has an inverter switch on the wall. I understand that some earlier years did not have such a switch. This switch is connected to the Tripp-Lite as a remote - ON puts the unit into supplying inverted power OR charging batteries. OFF puts the unit into Charge Only mode in which it only charges the batteries and does not supply power to the outlet(s).

    Share with us the make and model. You may be looking at the manual for the RV.

    Many IC's have separate switching for the charger and the inverter. Generally you do not need to turn off the inverter since an on-board transfer switch does the work.
  • Arvie1: Is there any place on your inverter/charger to plug in a household appliance? All inverters have 120 volts receptacles on them. A converter does not have any plug in places. A converter produces 12 volts, and that feeds to the 12 volt positive and negative terminal strips. From those terminal strips usually there are feeds to the battery to charge the battery.
  • Artum Snowbird, I appreciate your reply but I'm hoping to someone who has experience with a Roadtrek will share their experience. The owner's manual, which I always refer to is a little less than explicate regarding the inverter/charger.
  • Can't say for sure, but I think you are talking about a converter. The inverter takes 12 volt power and inverts it back to 120 volts. The converter converts 120 volt power from your plug in into 12 volts. The converter also charges the batteries when plugged in and turned on with the circuit breaker in the 120 volt circuit breaker panel.
