Voltage at campground low ??

IMHO everyone should have a EMS. It will be working for you all the time even if your not there.

A 4 volt drop is a big difference?

Ha not using the ac it’s 48 degs out,now the furnace is another story ??
It’s actually in the green but not by much
Mine at home is right at 120
So why would this be different ?
There are TWO breakers in the panel here both are on

Lots of wire between your campsite and the utility company transformer

Other people using power

creates voltage drop,

Ever lived in an old house in an old neighborhood?
Ever used 100 ft of extension cord, to power a power tool

Same thing

Your propane heater uses 12vdc for the blower
As long as your converter is working and the batteries are charged
It will work just fine
The blower uses less than 100w , only around 7 amps of 12vdc power

Portable electric heaters do not work at full heat, if the voltage is low

Fridge will cool better at voltages at or above 110v
Electric heating element does not perform well at low voltages
Should be good at 114v and 48° outside
But not when it's 100° and 100v power

Like I said in another post, I prefer propane for fridge operation
It's also more consistent heat for fridge operation

I actually like 120v compressor driven residential fridge best
But that is another topic

110 is considered "Acceptable" 104 is not just so you know

I have. hidden inside a lovely little HUGHES autoformer. You'd be scared to see some of the POST voltages but I had like 115 indoors. No problems.

When I finally get fully set up

Ok sorry I misread the meter, and the voltage dropped when I had an electric heater plugged in
So it’s at 118volt but if I turn the microwave on or the small electric heater it drops to 114 volt
I tried the ac, it tics it for a split second to 110 but then holds at 114, goes to 118 when off
How low is too low for the fridge

Most things are fine down to 105 volts.

I was camping at an older campground and it was hot outside. The campground was full and there were many large trailers and motor homes. As the day heated up I noticed that my AC was less and less efficient to the point that it would hardly cycle on. I learned by talking to my tech guy that when older systems like the one at the campground become overloaded the voltage drop can be alarming. I installed an inexpensive volt meter and now watch it when I am hooked up to a campground electrical system. I have seen that the voltage will drop as usage increases but this doesn't always happen. Yes, a poor connection at the post can cause issues but I believe that the overall capacity of the system is the real culprit. To start with, get a volt meter that you can simply plug into one of the outlets and then watch it when you are out.
The more expensive systems are better but you might want to start simple and see.

If the voltage was normal with his heater off, it is his site only. One space heater likely wouldn’t pull the whole campground system down. Many at once would, but then the voltage would be low no matter what, unless everyone turned theirs off at the same exact time. On page 2 the OP said it was 118V with his heater off and 114V with it on.

fridges don't care..that's just a heating element.

Because CG power is often inadequate for the loads it's supplying.

Or, as others have mentioned, there’s a poor connection at the campground pedestal. If him turning a load on inside his RV made that much of a difference, it’s likely a connection issue at his site.

luberhill,

The PI will disconnect the RV if voltage is low (I think 107 would be a better number for disconnect, for the roof air).

Or acquire an autoformer which will correct the low voltage.
