Xantrex RC7 GS Shore Power Setting

[Jean n Steve]

OK, so we're on our maiden voyage camping trip this weekend, connected to a 50A pedestal, and I can't set the Shore Power to anything greater than 30A? What gives? Am I unable to actually use all 50 Amps or am I missing something? I never needed to run a ton of electronics at once so I didn't blow any breakers...

If your looking at the inverter panel, the inverter will only pass 30 amps thru its internal pass thru switch.
Your still getting 50 amps on that leg, but only 30 thru the inverter powered circuits.

Thanks, TB! I couldn't find any explanation for that switch setting being limited to 30A.

This may help, look close to the end for setup.

Thanks! Are you talking about page 44 where it says this?

"This display has the same function as “Set Shore Power” on
page 15. You can set the shore power input (from 5 to 30
amps) so the total current draw from the charger does not
exceed the circuit breaker rating, to provide the maximum
current to the AC loads. Use the Settings button to change
this setting to match the circuit breaker rating of the AC
power source."

It doesn't really explain why the maximum amperage setting is only 30 amps. I know they designed the coach for 50 amps, but you can only set it for 30. Strange to me.

How much more power than 30A do you need for your charger?

I'm supposed to know this?

You don't have an EMS board that shows you what your amp are coming in.

That looks like a newer model than mine, Floyd. I do have a meter mode on mine, but I haven't played with it yet. Maybe when some of the newness wears off of camping in her and I get a little bored I'll start watching loads under differing conditions. I'm still in "play and enjoy mode" now.

If pedestal is offering 50a (have park tech measure it), you should have more than 30a into the coach - 30a to the inverter, 15-20a to water heater (assuming the breaker is on), and miscelaneous loads (fridge, CO detector and lights, etc). If not, any one or more of those could be the issue of limiting - ATS, surge protector, main breakers, or the main cable/contacts.

See, that's where the maximum "Shore Power" setting of 30 amps has me chasing my tail. If I'm connected to a 50A pedestal (let's assume I'm getting power as advertised) then why would I not have a "Shore Power" setting of 50 amps? I can understand that maybe the converter can only handle 30 amps, but to the newbie I should have a setting that reads 50 amps!

Thanks to you guys' help it's no longer an issue. Well, until I NEED 50 amps and I can't use it because the setting limits me to 30.

All of the country coaches I think comes with the Surge Guard system to protect your coach but I also go this to check the pedestal first before plugging my coach in just encase it is bad instead of messing up my coach then I plug into it.
Works great.

Steve, that setting on the inverter/charger panel is to manage the AC input to the charger. For example, if you are connected to a 15 amp shore outlet the charger needs to reduce it's output accordingly or it will open the 15 amp circuit breaker.

The setting does not manage what is coming into the coach. Only what is being consumed by the charger.

Good luck with your new coach.

Thanks, George. I couldn't find that anywhere in the documentation!
