HOW TO: Redarc DC to DC 11 Amp Output Trailer Charger Installation


Recommended Posts

FYI, related thread and discussion: https://olivertraveltrailers.com/forums/topic/4759-redarc-trailer-charger-mounted-inside-the-ollie-for-100-lithium-charge/?tab=comments#comment-49376

I won't add much commentary, it is pretty self explanatory. The instructions allow you to mount in any position, I chose horizontally with 1" cooling holes and a 1/2" gap between its housing and the mounting plate for cross flow of air. Note that there is a ton of extra space, I plan to add a small Victron MPPT Solar charge controller for my portable panel, it will go just to the rear of the Redarc, and there is room for another circuit breaker too.

My Land Cruiser 200 charging voltage is 13.6 volts with the trailer hooked up (using a digital OBD2 Scan Gauge).It never gets above 14 volts, regardless.

Here is the history using my VictronConnect app, showing the initial parasitic load (propane detector and stereo mostly) of about minus 0.3 amps, then the engine starts and the trailer battery voltage and current shoot up nicely, to just under 11 amps. It maintains that charge rate right up until the batteries are close to full.

The only fly in the ointment is that the wiring needs to be 12AWG or larger, all the way from tongue to charger. My Hull # 218 had a splice from 12 AWG down to 14 AWG, so I had to rewire the entire 7 wire harness, essentially. That is another thread. ... https://olivertraveltrailers.com/forums/topic/5271-how-to-junction-box-for-the-7-wire-trailer-harness-under-the-front-dinette-seat/?tab=comments#comment-54709

I went on a 90 minute, 40 mile test drive yesterday, it worked flawlessly, I can monitor the Victron app inside the truck, the sky was hazy high clouds, not ideal solar conditions, but the total charge current kept around 16 amps, going up to 22 when the sun broke through a little. 

Total cost was about $312, not including all my labor! Questions are welcome.
