Jack L Posted April 23, 2021 Report Share Posted April 23, 2021 If I am plugged into shore power, will I still have 12 volt lights if I have the battery disconnected ? My trailer is a three year old Forest River 50 Amp complete with a converter Jack L Quote Link to comment Share on other sites More sharing options...
Twotoes Posted April 23, 2021 Report Share Posted April 23, 2021 Your 12v lights run off the batteries. The shore power just goes into an inverter/converter to charge the batteries. Depending the make and model of your inverter/converter you may or may not be able to use your 12v system.

Jack L Posted April 23, 2021 Author Report Share Posted April 23, 2021 Thanks, I was thinking they should work, but wasn't sure Jack L Quote Link to comment Share on other sites More sharing options...
Kirk W Posted April 23, 2021 Report Share Posted April 23, 2021 The only reason it wouldn't would be if Forest River wired it strangely. I haven't worked with your particular trailer, but have never seen one that wouldn't. Quote Good travelin !...............KirkFull-time 11+ years......

lenp Posted April 25, 2021 Report Share Posted April 25, 2021 Your converter is designed to keep your batteries charged and does this by (1) monitoring the battery voltage to determine what the state of charge (SOC) is and (2) then suppling the appropriate voltage to the batteries to bring them up to a 100% SOC. This voltage will vary depending on the SOC of the battery. Without batteries connected the converter will probable still provide something close to 12-13 volts but I would certainly want to measure it with a good quality volt meter before I ran the entire RV from it. Voltage could be low or excessive causing damage to some components. Plus, the batteries act as a filtering device to smooth the output of the converter. Without the smoothing there could be excessive noise riding on the 12 volts which could also damage components. Bottom line is the converter is designed to have batteries connected!
