So, does the wf-9855 (about 2018) support agm batteries as well as lead acid?

Is it ok that it keeps on turning on and off??

Hey there! Have a 2023 Winnebago Solis Pocket and having charging probs for the house batts from while engine is running. Solar and shore power charges the house batts. Trying to diagnose the issue. Have narrowed down to: fuse to house batts, relay or solenoid from the chassis batt or alternator. Typically where is the fuse from the charger to the house batts? I’d like to check this as it seems like the simplest issue? Thanks!

Question, does the alternator current to charge the house batteries connect to the charger? I am not charging the house batts while the engine is running. Thanks, very good information!

Great video! Hey I'm getting 13.70 to my dc side on fuse panel but I'm not getting 13.70 on the fuse block on battery positive wire. New converter that's only getting ac power in but not DC out. Does this sound like I have a bad fuse panel? Thanks

After draining the battery, Do you have to be on shore power to Re-charge or can I be on solar power and also charge with the 12 volt from ombilical to truck? (currently Boondocking on the road)

Replace with the Progressive PD4135KW2BV

I had the same problem with my 560ah LifePO4 battery. I'm using a Victron Smart Shunt so I can see the exact voltages and current. I discharged the battery till it shut off (it took days) and plugged the RV into shore power. It ran for a few hours at close to 55a then it dropped to 12-15 a. Still with a green light. I read others succeeded in geting it to auto detect with a blue light only to have it switch back to green lead acid mode. I found in my research that if you ask WFCO they will send you a jumper to force it to Lithium Mode, It goes on the small board int the back on connector J4 pins 5 and 6 with a 1k ohm resistor. I made my own and it does now come on with the blue light in lithium mode. However I am still not happy. It went into bulk mode and then into 14.6v absorption for 4 hours which is way to long. Then it dialed back to 13.75 which is a little high. That was last night.. This morning it was back at 14.6. Progressive dinamics replacement with a jumper for lithium mode. I called them and it is only one stage at 14.4v even after it is full. They have a differant one that is 2 stage but it is not a direct replacement. It has to be mounted some where else. I am going to try and see if I can adjust the WFCO voltage down to less agressive levels 13.5 v float % 14.4v absorpsion. Higher voltages are unnecessary and will shorten the life of a LiFePO4 lithium battery.

I have this same converter and the fuse board seems wronh i have to green 30amp fuse on bttm says reverse protection and then f6 is right above the two 30amp f6 says its a 15amp red wire to battery positive and as soon as i plug into shore power it pops f6 15amp fuse then i lose all 12v power i can unplug shore and put new fuse in and its good until i plug it in again. So i checked the positive conection at battery for continuity and just like that i have a dead short so i go back to converter to check at battery connection f6 15amp and once i put the 15amp so i can trace what fuse is giving me dead short every fuse oulet on the board shows contuinity so is the i ground to heater then touch any fuse sadder spot.i get a loud beep so it prettey much makes it imposible to trace where the dead short is with how the fuse board is designed very disapointing any ideas

I have removed the "AD" converter from our last two RVs. Auto detect units that DO NOT DETECT. WFCO should go back to a simple LA-LI switch. AD is a solution to a problem that doesn't exist.

HELP ! WFCO-WF 8725 DC power stopped working Fuses OK Battery is charged if plugged into AC all DC works Why DC stopped working ?

Well I can't edit so I had add a new comment lol is there a fuse I could pull to disable the battery charger

How do i turn off the battery charger without adding more equipment?

Mine charges my lithium ion to 100%, but it takes 3-5 business days to do so. I rqn my batteries down to 50% and plugged into 50amp shore power. This piece of garbage never charged beyond 8 amps. Pretty embarrassing for a supposed 55amp charger.

Don’t buy this crap it doesn’t work

Does anyone check WFCO emails?, I sent one about a week ago and no response.

How would you upgrade from a WF-5110R 1000 watt inverter to a WF-5220 2000 Watt inverter? The WF-5220 2000 inverter does not come with the AC shoreline 120 V plug like the 1000 watt inverter has. I have contacted your Tech Support both by phone and sent emails. No response. Can you advise?

Battery connection. The video didn't include attaching the wire(s) to the house battery.

How long are you going to keep pushing your "Auto Detect" that doesn't? Just go back to the switch. Nobody keeps changing their battery type back and forth. You must still think auto detect is a marketing advantage when it's nothing but problems for so many users? There shouldn't be a need to pull converters, send them back, replace boards. What a mess. It's not "automatic" if the user has to jump through hoops to get it to work. Every forum and group is full of complaints. What a poor design.

I need the “slide out” relay for the distribution panel in my 2007 fr Georgetown rv

my 1989 terry resort has stock 30 amp fuse panel i ordered the wfco 30 amp an i got the 55 amp wf-8955 model.... can i still use this on my 30 amp system? i dont have any batteries but may add 1 or 2

Can you wire your inverter into the generator wiring in your transfer switch to your 8955 to power the 120 V in your trailer? Do you need to shut off your converter breaker then to use your inverter?

In my cigarette lighter accessory socket fuse I have both side voltage when ignition is on. When off is no voltage. I need this just when ignition is on. Why is in both side ?

In this video's senario I observe a 30 Amp Main (Good) and a 20 Amp Converter, my current breaker is 30-15 should I upgrade to a 20 amp for the converter?

Mine has all fuses and still does not work. Unit is not even 2 years old

If someone who's not familiar with using a multimeter uses this video and starts probing around, they are going to get fried.🌩🔌⚡

I installed all new coach batteries. Now, when I turn on my "power button" my vent fan comes on. This has never happened before. Now I just found out that once I start driving the van, I can't turn off the fan. Not even manually. Any thoughts? Anyone?

I'm still a bit confused as to where the 120volt output is connected. Is this connected to the power converter? If so, does it connect to one of the breakers in the converter?

How do I get my hands on one of those 12v distribution boards?

Why wouldn't you just out on a switch. I have lithium and charge light is green still.

Is there any temperature compensation going on for float and charging voltages?

Quick question, I have a 8935 p in my truck camper, and want to upgrade to lithium batteries, can I install an 8955-AD with out having any issues? Or can I only replace with the 8935-AD? Thanks for your time

If I am on lead acid batteries and I change to lithium, I’m told the lithium battery will only reach an 80% charge with the charger. If the “complete cycle” only charges the new lithium battery to 80% is that enough for the charger to “auto-detect” a lithium battery and switch to a lithium profile, and then charge it to 100% ? Thank you.

Seems like audio isn't working from my end on this video

I've got a 2007 Keystone, Laredo 27RL - my 12 VDC seems to be out at all lights,fans, etc. When I cycle the 110 VAC breaker that powers the inverter, the 12 VDC power seems to come on only momentarily then completely nothing again. No warning LEDs are apparent at the 15 amp fuses (blown fuse indicators) so would/could this be an indicator that the power A/C to D/C inverter is failed - and would a replacement be available from WFCO directly if a part number is found?? Any thoughts would be greatly appreciated. Thanks and great video!!!

I have the wf-600-th model. What is the white AC output wire? What is it hooked up too? I cannot reset my 7amp circuit breaker on my inverter either. My inverter has no lights lit up. I tested the battery cables going to it and they are at 13.58v

Just did it, 10 minutes max, got 4 latches from Amazon for $5. Thanks for creating the video.

Great video. Very informative. It could be improved with some simple editing such as removing the pauses as the camera is repositioned for the closeups. FYI - it’s not a “square drive” screwdriver; it’s called a “Robertson” screwdriver. 🇨🇦

Need a user friendly switch instead of auto detect lithium feature 😢😢😢

So I purposely put a blown fuse into the slot and no LED turns on. My shore isn’t charging my house battery. Do I have a bad converter?

I’m trying to figure out why my 8735-P is not charging my battery when connected to shore.

All my fuses are intact but it’s still not charging. When I replace the fuse, the fan comes on momentarily. What’s going on?

ok what kind of breakers do these use, the one i have now uses QT breakers

Great Video- I currently have a WF-8560 and looking to replace it with one that has Auto detect or maybe simple replace the board with a lithium model...Let me know if this is possible ?? The instructions are great.

If only every manufacturer would produce and post videos of this high value life would be so much easier. Thank you for this.

My wfco 8955ad mostly charges to between 13.22v and 13.32v or 70-90% but not 100%. I've watched the wfco videos and confirmed it's in lithium mode. What's needed to get to 100%?

In my RV it tge fan starts when charging house batteries and and makes trrrr sound. At tgat moment tge fan stops for a few seconds and starts back again repeating trrrrrrrrrrrrr sound which is annoying. Any thoughts what might cause it? Thanks for your responses!
