My multimeter's out and I'm ready to tackle this RV electrical mess myself — pretty sure the inverter's the culprit but need to know where to start. I have a 2000 Winnebago Ultimate Advantage with four deep cycle house batteries and recently installed a Xantrex 758 inverter to replace my old Freedom 15 unit. The first time I tried using the inverter power while unplugged from shore power, something very strange happened - a hair dryer in the bathroom started running by itself and wouldn't shut off when I tried the switch. I had to unplug it, and the handle was warm. The hair dryer appears to be ruined now.

When I bought the Xantrex 758, I paid around $725 for what I thought was a good unit, but I'm now learning there's a difference between modified sine wave and pure sine wave inverters. I wasn't aware of this distinction when I made the purchase, and it turns out the 758 is a modified sine wave unit. I've since heard that modern electronics, especially things like residential refrigerators, computers, and sensitive electronic components, can be damaged by modified sine wave power.

I'm really concerned about potentially damaging my new residential refrigerator, stereo system, and computer equipment. Should I be worried about using this modified sine wave inverter with modern RV electronics? Is the hair dryer incident a sign that I need to upgrade to a pure sine wave unit, or are there other factors that could have caused this problem? I'm trying to understand if my current setup is putting my expensive electronics at risk. …more

Walked into my new RV and discovered the previous owner left the Xantrex Freedom X 1200 inverter constantly throwing critical 11.2V low battery warnings. My Xantrex Freedom X 1200 inverter is displaying warning indicators on the panel, and I'm seeing some concerning voltage readings that have me worried about potential damage to my electrical system.

Here's the complete situation: My house battery is reading 11.2 volts, while the chassis battery shows 13.1 volts. The inverter panel is lit up with what I assume are low voltage warnings. I've been noticing the interior lights dimming significantly, especially when trying to run any appliances through the inverter. To make matters worse, it's currently overcast and getting dark, so my solar panels aren't generating any meaningful charge to help recover the battery.

I'm particularly concerned because I know lead-acid batteries can be permanently damaged if they're discharged too deeply. The voltage reading of 11.2V seems critically low to me, but I want to understand exactly how urgent this situation is and what my immediate next steps should be. Should I be looking at shore power connection, generator use, or is there something wrong with my charging system that caused this in the first place? I need to know both the immediate fix and what might have caused this failure. …more

Called three RV supply shops about replacing my failed Xantrex inverter/charger in my 2001 Fleetwood Expedition — but do I even need one or just wasting money? Since I never utilize the inverter function and rely exclusively on generator or shore power for 120V loads, I'm evaluating whether complete removal is feasible rather than expensive replacement.

My primary concern is maintaining proper 12V DC charging capabilities for house batteries that power lighting, water pump, and ventilation systems. Would installing a standalone battery charger provide adequate charging and maintenance functionality? Are there any critical system integration issues I need to address, particularly regarding power transfer switching between shore power and generator sources? …more

Xantrex RV3012GS inverter is throwing a fault code and the repair shop wants $2,800 to fix it. Inverter is 8 years old and I'm debating between repair, buying a refurbished unit, or upgrading to something newer. What are my realistic options here? …more

Our 2017 Prevost coach's Outback VFX2812M inverter/charger died completely and my wife keeps asking why nothing electrical works anymore. The unit appears to be getting power since the cooling fan kicks on and runs, and when connected to shore power, 120VAC passes through just fine. However, when I disconnect from shore power and shut down the generator, the inverter completely fails to produce any AC power output.

What's particularly concerning is that the MATE digital controller inside the coach never powers on - the display remains completely blank with no indicator lights whatsoever. I have a brand new 12VDC battery bank, so I don't believe it's a battery issue. I've already tried disconnecting both AC and DC connections and reconnecting them, but aside from the fan running for about a minute during startup, nothing else happens.

I'm wondering if there might be internal fuses within the VFX2812M that I should be checking, and also whether the blank MATE controller display might be related to the same underlying problem. What are the most likely culprits when you have fan operation but no inverter function and no controller display? …more

Wondering why the manual shows a reset breaker location on my Freedom 20D inverter that doesn't match what I'm actually seeing inside the unit? My 1999 motorhome has a Freedom 20D inverter that was working fine until recently. I was running some heaters during cold weather and when I started the engine, something went wrong and I lost one of the AC circuits completely.

I've reset all the house breakers and checked every GFCI I could find. All the other circuits work fine, but this one inverter circuit has no power at all. When I look at the inverter itself, none of the breakers appear to have tripped - they all look normal to me.

I'm wondering if there might be some kind of internal breaker or component that failed inside the inverter that I can't see? Is this something that can be repaired, or am I looking at replacing the whole unit? Any help would be greatly appreciated since I'm not sure what to check next! …more
