Renogy DC to DC Charger
*** Update ***
Well, I am now officially a full time (or mostly full time) rv'er. I wanted to give an update with my findings with the DC-to-DC charger, now that we have been on the road for about a month now. I hope it might help others if they have problems.
I have identified a few things that happen to the DC-DC charger.
1. Circuit blows next to the battery in the engine compartment:
I think this happens when I have a lot of rpm, for example when going up steep hills. After going up steep hill's I will check the breaker when I get a chance.
2. DC-DC charger fails to charge, and there is a red light on the charger:
This was a very interesting issue and took a little time to solve. What I found that is when plug into shore power, this will happen. So, what I do is turn off the circuit breaker by the DC-DC charger, so power does not get to it when plugged in.
So, now every time we take off, I check for the popped circuit breaker and the red light and then verify that the DC-DC charger is working. I will also check how its working every time we stop.
All in all I love having the DC-DC charger. I can now run the inverter when driving so I can run the fridge on AC instead of propane, and at the same time charge my batteries. I also figure that is a big safety feature, not having the propane on.
PS. We are currently at Palm Canyon, in Kofa Wildlife refuge area. Thanks to a video from Ray about 5 or 6 years ago. What a wonderful spot.
