2022 Micro Minnie FLX Parasitic Load?

[snapper0245]

I have a 2022 FLX. Trying to figure out how to reduce or eliminate the parasitic load when no load is being used by any of the appliances or humans.

I suspect that it has to do with the Xantrex. I have changed the settings on Xantrex and it helped to reduce the parasitic load. However, the Xantrex shut down and I could not restart it without plugging back into shore power. This forum helped with the proper settings for the Xantrex and I whiched them back to those settings.

When I push the powder button on the Xantrex nothing happens. The unit does not appear to go into standby nor does is shut down. It just stays on.

I can lose 10% of my battery every day without much solar just to parasitic load somewhere.

So, if I am boondocking and I want to save battery, how do I do that?

thanks

Are you pushing the button on the Xantrex main unit or on a remote panel?
If on a remote panel, the main unit button must be in the off position for the remote to respond to the power button.

We don't get much in the way of online wiring help for the trailer group, so some guessing/testing may be needed.
One part of the puzzle may be the way safety items are wired and not disconnected when we use the normal battery cutoff switches.
Things like steps, radio presets, and any automatic things are often still powered. One easy to check might be the CO and propane detectors if they have LED lights on them. If your do the cutoff and that LED is still on, it is still drawing power!

But there are many reports of problems with some of the trailer group which might also be involved. Do you have breakers/fuses out under the trailer frame in front? Possibly where you need to lay down and look up like at the bottom of the propane tanks?
If you have those, it seems to be a pretty common problems for them to become corroded/dirty, etc. as they are in the direct weather spray from any rain when driving.
They seem to be mounted on a very low (1/2 inch?) standoff to separate the power from ground on the frame! That short distance and the ton of water splash is one that I feel sure to eventually lead to a high resistance short that lets power leak to ground!

Maybe worth a quick look under there for what you have on your specific RV? If you find a tub full of wiring of various sorts, that would be one I might suggest checking first!

Post number 9 and 11 of this posting is what you might have?? UGH??

Thank you for the reply and the help. My Xantrex main unit is tucked away under a bed and I had to pull a panel to get to it. Once I did that, I cant see the control panel and there is only a couple of inches clearance between that and the cabinet wall.

With that said, I did "find" a button on it that I was hoping was power. I pushed it and now I am able to turn my remote panel on and off. When the panel is off, the parasite load disappears.

This is our first camper, and I am disappointed in Winnebago for not having more information on how this dang FLX system works. Feel like I need to be an electrical engineer with this thing.

Thank you very much for the help! Appears to of taken care of my problem.

I just re-read my original post. So sorry about the poor grammar and spelling. Was trying to get it sent before I had to jump on a conference call, and I should have known better.

No big thing to not quite get written what we like later!
But as a thing to know for future?
RV are different than many things we deal with in a lot of small ways. One is how scattered the info we need. I find it has some aspects which are like the normal car but often other points are very different. We may need to take it to a different garage to get good service.
One of the biggies on repair is that I find it more like the sticks and bricks houses than we might expect! Instead of a car which we tank to a garage for most things, we need to go to different builders for info on the different parts.
More like we do for things at home? When we want to fix the frig, furnace, or plumbing, we need different folks to give us the details!
Like the guy who built the house, Winnebago doesn't do very much close work on the things they buy from others and install in the RV!
As things in electronics got more and more complex, one person nor place will have the true experts needed to deal with products than can be new or 30-40 years old!
So we get better info if we go to the folks who really know the item as they built it!
Kind of the same if we buy a house and the roof leaks a few years later, we have to go to a roofer to get the best!
For the charging system, looking at the until for a brand and model and then an online search is a good way to start as it cuts lots of chase involved. Frig, furnace, and vent fans are all the same way. We have to dig it out from lots of different places!

snapper0245,
You need an electrical engineer... and we happen to have one here that works for the Lithionics battery company and he's well versed in how your FLX system works.

Here's a link to the Lithionics thread and if you post there you should get a response from the engineer in a day or so.

Winnebago designed the FLX travel trailers and then made a good faith effort to train their dealers so that the dealer could tech you how to work everything. That was a failed plan because the dealers couldn't be bothered and who knows what employee at each dealership was trained, who they shared their training with and even if they are still employed by the dealership. Yes, it's a mess.

One more thing it's vital to tell us what RV you have. You don't have a FLX you have a Micro Minnie FLX, and there a model number, as well. We don't know what you have it could be a 2108. Do you know what you have?

By the way I looked at your profile and you've entered your RV info incorrectly. You listed that you have a Minnie Winnie. But that's not possible. A Minnie Winnie is a Class C motorhome, not a travel trailer. And they have not made any FLX versions of that motorhome. So, as I mentioned above, you have a Micro Minnie FLX (model number?). It's important to know this info and it's equally as important to mention this info in your posts.

Thanks.

Well, the great thing is that the first guy knew what I was wanting and took care of my issue.

By "first guy" I guess you mean the 2nd post in the thread posted by WinniMN?

If so.. that's great. So happy you found your solution.

I thought it was common knowledge that every RV owner needs to be an electrician, plumber, carpenter and auto-mechanic, all in one

It's not a WGO specific issue, entire RV industry is like that. OEMs expect dealers to train customers and dealers expect to collect checks and kick customers out the door as quickly as possible.

To your original issue, I can confirm that Xantrex idle load is around 2A, so you would loose around 50AH in a 24hrs period, or completely deplete your 320AH battery in around 6-7 days, assuming no charging and no other loads.

I think Xantrex has a setting for sleep mode where it auto wakes up when detecting AC load above 25W, but I personally think it's better to turn it off manually and turn on when needed. Sleep mode consumes less, but still not zero, and would probably flicker when small AC loads are present such as phone chargers, etc.

Loads on RV are pretty much like water loss in the house.
It may not be the big things we think about when we get a big loss or a big bill in the case of lost water.
There can be just a lot of small loss that makes a big total!
A little loss on equipment, a little loss on detectors, etc. left powered and maybe a little loss at the connections shorting to the frame and suddenly we wonder where all our power goes!
Just like at the house when we drag the kids for staying the shower too long or nag the wife for watering flowers? Maybe the real problem is that sneaky little rubber flap in the stool that never closes!
We waste so much-- just simply because we are trained and used to wasting so much!

Well with a farm background we are used to being a jack of all trades.

Thanks for the info.
