Do I leave the shore power on ?

Hello,

We will be keeping our coach at a campground for two months and using it there three to four day's a week. I have two questions,

1) Should I shut the shore power off when we leave or can I leave it on the 50 amps. ? I want to have power to the refer. and keep the batteries charged.

2) Can I run the engine when plugged into shore power ?

Thanks for your help.

Mattpro

Hi mattpro....I leave my shore power on for 6 months at my campground for the same reasons you want too. This is my third season with no problems.
Also, I sometimes run my engine and leave the shore power hooked up. In fact, if your coach is equiped right, you can start your generator to exercise it once a month while hooked up to shore power. Your converter should switch over to the generator as this takes first priorty.

Make sure your battery charger is not the type that will boil your batteries dry if left on for an extended time. You can get a battery disconnect or use a smart charger if the RV has the normal dumb charger type.

Thanks for the quick reply, I was concerned that my converter would be working to hard, I had one go out when the coach was new. I have started the generator when hooked up to the house and it tripped a 20 amp breaker and I have never run the engine when hooked up to power.

To Two Bits point, I should check the water in the batteries each month.

Thanks again

Mattpro

By default the generator will take priority over shore power. However---sometimes things don't go right. So I always unhook shore power when running Gen.

Hi Mattpro,
One can run the engine with shore power connected. If you asked this question because you'll be starting the engine and running it in place, at the camp site, please reconsider. There may be no benefit to doing this. Harm may be done by doing this.

Hi Gary,

My reasoning was, not to let the engine sit without running it a few times. We have never stayed in one place that long so I'm trying to out think myself I guess

Re Convertes: Some rigs have single stage battery boilers.. Others have lovely 3-stage battery babying converters.. Damon blessed me with a Progressive Dynamics 9180 with wizard.. Will it boil the batteries dry.. YES, how long does it take,, long about 14 months or more.. IN short, that's one very good converter.

SOme of 'em 14 DAYS and your batteries are shot

SO post the make and model of your converter. That is the deciding factor

Hi Mattpro,
Let the engine sit idle. Loose no sleep over letting it set for a few months. Once one starts an engine all the components should be brought up to operating temp (engine, tranny, exhaust, etc.) this can not happen sitting at a campsite. In a single word, moisture. Let the engine sit and it will be fine. Start it up and sit at the camp site will allow moisture to be partially burned (but not all). Heat and moisture will do damage to whatever they are left to contact.

Thanks,

I will look at the converter this weekend and not worry about the engine, I never thought about moisture. Thanks for the help, We haven't been doing this to long and it's good to come here for some help.

Oh, one other thing to check... Does your rig charge the CHASSIS (Starting) battery when on shore power? If not there are 3 options

1: Xantrex Echo charge
2: Trick-l-start
3: Jumper wire (SEE NOTES)

The first two are simple 3 wire installs, #2 is less expensive, they will charge the chassis battery but will not let it discharge the house batteries excessively should it short. (they work much the same as my battery control system by Inteletec)

The third method I do not recommend for long term use. (if one battery shorts, they all need to be replaced)

The Trick-l-start is a perment additition to your rig, and insures a full starting battery too. (Or the 1st one I listed at a higher price)
