Inverter comm loss when master off
« on: October 09, 2017, 11:26:02 AM »
I put our MH away in storage, and noticed when all the master switches are off I have a lit screen on the inverter control with a red light and (communication loss) on the display.  I never noticed this before.  Is that normal?  Seems like that may have been what got my batteries last winter.

I have the Magnum 2800 MS2812

By "inverter control", do you mean a remote display panel of some sort? Or the Magnum itself (in/near battery compartment).

Comm Loss typically means just that - one unit is no longer in touch with another. Not surprising if you have all battery power disconnected with the "master switches".

I meant the remote display.  The alarm makes sense, but the fact it stays powered with masters off doesn't.
I just learned the big brother Tour had an inverter shut off in the basement cabinet.  Guess i better see if i can find it if i have one.

Maybe the remote gets its power from the chassis battery?

I don't remember for sure but I'm thinking the remote panel is powered from the interface cable. I replaced my Xantrex with the Magnum PSW two years ago and I already forgot the details  >:(

I have the manuals, guess I better do some studying.  The Chassis and Coach battery switches are both off and the only thing that works is the step, and that interface.  I'll go up this week and see if shutting off the inverter with the power button on the unit itself will shut that off.

The remote having power shouldn't have killed your batteries. The remote itself should not draw much power. Evidently the remote is wired directly to 12V somewhere, but the master switches disconnect the inverter from the batteries. 

If you charged your house batteries every 4-6 weeks that is good.  If you left them for 4-6 months w/o charging them than is not good. 

If your chassis battery went dead if the engine wasn't started every 2-3 weeks or so to charge the battery, that may be normal. The engine computer may draw some power.

That's exactly what I did last year AStravelers, a costly mistake - By November I didn't want to start anything in the cold so I let it go until Memorial Day.  I'll know better this winter.  My daughter pointed out that they could have already been damaged sitting on the Dealer lot too.  If I had known better I might have asked for them to be replaced.

As far as the comm loss - I guess I just hadn't seen it before with the masters off.  The manual never mentions it, except to say it means I have to reset the panel and the inverter to clear it up.  I'll have to play with it some more this weekend. 

The chassis batteries did fine last year - they are lead acid, the coach is AGM.

AGM is lead-acid too, exactly the same chemistry. I suspect you meant AGM for the house vs flooded cell for the chassis battery.

You could pull the chassis batteries and store them somewhere heated. If they are discharged they can freeze, not a good thing.

Yes I suppose technically.  "flooded" is a new term for me, I guess to distinguish it from all the other new varieties out there.

That is a lot of work - I tell you.  It took a lot just to replace them.  Not only are they in a not so convenient space between the frame rails under the slide out tray, they weigh almost 150 lbs a piece and there are 6 of them, and a dozen battery cables to sort out.   I like to occasionally use the coach in the winter and the harder it is to do that, the less I will use it.  I would rather just disconnect them if I have to, but even that is not real simple because the cabinet doors don't open wide enough in the garage to allow the slide tray to come out to get to the batteries.  I would have to start it on chassis batteries and pull it out to hook up the coach batteries.

Chassis and Coach cutoff switches don't kill the big inverters as they require far too much power to be looping them around the coach through switches, they are cabled directly to the battery. The house cutoff contactor kills only the coach. You didn't mention what remote and/or additional widgets you have on the Magnum, but the ME-RC and ARC panels are powered via the remote cable from the inverter. Unless you have the remote off module installed on the Magnum buss, the inverter will stay on regardless of having the coach powered or not. I have an optional buss widget that shuts off the inverter when I kill the coach batteries, but the inverter only goes into standby and cannot be powered On. Any of these big inverters can kill the batteries over time. I have a manual master house battery shutdown for emergency shutdown, but this isn't the norm.

Kev, I don't think I do.  The owner didn't provide outlets in the garages so I assume that was to prevent us from plugging in, but I have thought about the garage door outlet at the ceiling.  The only problem is if I pop the breaker I may shut down the whole row of garage doors and I'll be ejected for sure :) 

Do you get this on your Tour if you kill the two battery switches?

Jeff, I'm looking at the Winnebago drawings and it looks like you are right, the inverter connects direct to the coach batteries, and then the batteries themselves are cabled back to the rear where the cut off solenoids are located.   The battery switches would isolate the batteries from the coach, but not the inverter. 

I don't see a number on my remote but it is pictured above.  The remote lets me shut off the inverter as the green light on the inverter goes off, but as soon as I kick off the master switch to the coach, I get the fault.  Would that be normal?  I have to confess I didn't notice it before.

Except I don't really have posts.  I could rig up a disconnect I suppose - just a real bear to get to.  I bet I could put it on the inverter itself, which would be easy to get to, as long as it didn't cause harm to the inverter.

You could use a marine battery switch

It could be installed near the inverter

That would probably be easier to install and get to!  Seems odd that I would have to do that though.  Oh well, the new land of inverters that I'm not used to.

There's nothing wrong with your system. I have the same inverter and remote, and yes... if I turn the Coach-Battery disconnect switch off, I get a "Lost Comm" error message and a red LED. It doesn't make any difference if the inverter is on or off when the disconnect switch is turned off - I get the same error message. (It goes away when you reconnect power.)

I do not get any inverter error messages when I turn the Chassis-Battery disconnect switch off, nor would I expect to, since the inverter isn't wired to the chassis batteries.

Ah, good to know Kevin, thanks! That was my original concern on this post.  Mine also returns to normal readings when I turn back on the disconnect. 

Now that I know nothing is broke, I can figure out a way to fix it whether it needs it or not :)  I still may try a disconnect to drop off that inverter, in case we get so covered in snow I can't get to the RV for a few months.

The discussion about disconnecting the inverter.  Is there a chance you are leaving the inverter turned on?

When I turn off my Magnum 2000 watt PSW inverter it doesn't use any current.  So I don't worry about disconnecting it when off of shore power.  I have the remote control panel so turning off and on the inverter is easy.

However, if I leave it turned on, it pulls about 1.5 amps even when there is no 120V device load on, all inverter AC sub panel CB's off.

Al, I am able to turn off the inverter from the remote, and I verified that inverter itself goes off (green light off).  But even then I get the comm fault on the remote when the master switches are turned off.  The display shuts off after a while, but the red LED stays on.  I suppose that could be a small drain over time.

Well Lucky Day!!

I asked the owner of the garages if I could get an outlet, as I noticed my daughters garage next to me has one and I don't.  I even offered to pay.  He said oh man, must have missed one and he would take care of it right away - no charge!  I told him two, as we actually have two garages there and neither has an outlet. 

I've been storing there for 11 years and always assumed he did that on purpose to keep people from plugging in!  I could have been using a maintenance charger all this time.  I think this cures any issues I have.

That is good news. With your charging system and AGMs, you can leave it plugged in for months without fear of overcharging. And you don't have to lug those things out from between the frame rails!

i have this one installed on the wall of the bed pedestal. I moved everything connoted to the house batteries under the bad in a utility area that's closed off. Everything connects here: Solar, house breakers, Magnum, etc., then through the 300A battery switch, then out to the batteries. Way cleaner install, no crap all over all the cabling, no clutter, and only two 4/0 cables on the batteries.

Can't help you on that remote, I'll have to look at the manual but somehow it knows that the power has disappeared .

Would you plug the RV into the 110 or get a separate charger and connect to the coach battery jump posts provided in the LR cabinet?  If using the RV cord direct into the outlet, will it still charge with the coach and chassis disconnects off?

I would plug your shore power cord (with a 15/20 amp adapter of course) directly into the A/C socket. You have to leave your disconnect switches on, because if you turn them off while plugged into shore-power, your 12 volt systems will still work, but your charger won't charge. Our Tour's charging system will charge both the house and chassis batteries while on shore-power. I think you have the same setup.

I'd also recommend that the house batteries be fully charged (or close to it) when you put the coach in storage. The Magnum 2812 has a 150 amp charger and it's generating a fair amount of heat when when it's running full throttle (so to speak.) I don't know how many amps it's pulling (never paid attention) but if your A/C socket is on a long string of sockets, I'd be a little concerned about tripping a breaker at the facility.

Ya, tripping the breaker is what is worrying me as it probably powers several garages. I guess I can try it for a bit and see what happens.

Nothing serious you understand. 

Yikes! Hope all comes out well.  I had quadruple open heart surgery four years ago and I'm really impressed with how the medical field has come along. It's really amazing what they can do for you.

Yeah, that's certainly a good reason not to come. We completely understand. Our prayers and very best wishes are with all of you. On a positive note, a friend/retired DEA agent I know got a total heart transplant last year and it's truly remarkable how well he's doing. It's hard to believe he's the same guy. He takes a bunch of pills each day, but he could probably walk us all under the table. We'll see you next year. KOFA's not going anywhere.

Brad: without going back to look at your charger panel (but I think you have the mini) the ME-RC and ME-ARC have the capability to set the max AC current draw. I rarely take an external generator anymore, but can easily charge the coach on a 1000w generator. I simply set the panel to my shore supply and the Magnum manages the max draw through the inverter and charger together. If yours doesn't do that and you are hanging at friends houses, etc., with 15A service, you might consider upgrading the panel.
Now to go read up on that little panel...

(Later)....  Been reading. You do have control of max load on that panel..  Setup 01:Shore. Just matchnthe breaker and the load preset. Just be aware that calculation does not include fridge on AC, MW, or HVAC

Still the question is why you get a comm error? That panel is powered from the Magnum itself. Is there anything plugged in to the StackPort (Red) on the inverter?

PS- Just read your last comments.. Yikes.. hope everything turns out good. I have a friend that just went through the same and he's already back on his feet and starting to be the big ol' PITA he's always been :)
He's even talking about Quartzsite again :).

I think the remote is actually plugged into the Stackport, but I'll have to look again.  I was thinking of trying to unplug it there.  That is super info on being able to control the max load!  Thank you.  I'm anxious to try it.

Thank you all for the kind words, prayers and well wishes for Dory!  Your experiences are good news, as it is consistent with what the hospital is saying. 

She is currently in the final stages of recovery from having an LVAD (left ventricular assist device) installed which involved open heart surgery to install the pump into the left ventricle and aorta, powered by a control system and batteries from the outside (her and my world revolves around batteries..........:) ).  She is on the transplant list with a pretty high priority because the LVAD is considered life support.   We get the MH out to go to local state parks, but we are pretty much restricted to 2 hours from home, waiting for the call.  Ironically, with all the back up systems on the MH (inverter, generator) she is safer in the MH than at home :)

Careful.. you might let all the smoke out. The panel should be plugged into the remote (Blue on the 2012) port only. does the inverter turn itself off when you kill the house batteries? If so you probably have a remote sense plugged into the stack port somewhere. magnum makes some cool little widgets for controlling the box, like a simple tiny switch to turn it on or off from bed, or another that you simply remove 12v and it shuts the inverter off. I installed that one, but think I'll install a timer that I can turn off the system for those who seem to think the TV is a nightlight when boondocking.  >:(

Both switches on my coach are off but the light on my OBDll reader is lit.  I doubt that's a big draw, but I wonder what else might be drawing my chassis battery down.  I don't have an inverter.

On Winnebago units the entry steps operate off the chassis bank, I think I remember reading about reports of something going wrong with steps that causes a constant current draw.

I remember that on the step too, something got stuck and killed the battery.  I just don't remember what it was posted under

Multiple things bypass the chassis battery disconnect switch, e.g. the electric step motor, the LP and CO gas detectors, and probably the ECM (engine computer) memory. These fall into the category of safety devices or functions necessary to restore operation in the future.

John and Brad, if you find that post, please repost.  It's likely more than a Winnebago issue.  The steps on our Pace Arrow failed to retract twice when we started out.  Fortunately the DW caught it.  The on-off switch seems to have a mind of its own.

On Winnebago units, the step extension and retraction is initiated by a magnetic reed switch on the entry door, the steps stop retracting or extending when the monitored step motor current exceeds a predetermined value.
