Good info. You confirmed what I suspected my power issue is. Thanks

Great video. I don't know how many times I've run across folks who were dead in the water and didn't even know where to start. I advise them to check the ATS, and their reply is what's that. Over the years, I've replaced mine twice. In both instances their was a problem with the buss bar. Since then, during my annual maintenance, I check all the connections, and usually, at least one of them is just a 1/4 turn lose. Since I started doing this, I've never had a problem. Keep up the videos you were a great help in designing my lithium/solar system.

It's definitely one of those black boxes that many RV owners wonder "what is that thing?" You're right. Routine checks on the torque is important.

The last time my transfer switch didn’t want to work I traced it down to the pedestal. Someone had been meddling in there. The neutral was unhooked and taped. I was cussing the RV since it was late at night and dark and just ended up putting my battery charger on my battery bank for the night. The next day I figured it all out and had to apologize. 😂😂

Great video Brian! When I bought the RV new I knew this was a must have so I built my own 50 AMP Transfer Switch for my RV. I had the same type of issues with the ones you fine online etc.. Originally everything was 30 Amps but I upgraded everything to 50 A to accommodate everything and not having to be conservative. lol. I put all the controls for the Transfer Switch in a 12"x12" x6" Nema 3R enclosure. I put twist lock receptacles on my enclosure so that it is pretty much plug-and-play (quick change). My Solar is priority and my generator or shore power is my secondary. It runs 24 seven Year round and so far it's been working flawlessly for the past eight years. Transfer switches are definitely a must have for convenience. Keep up the awesome work and really appreciate you sharing this video with us. I'm sure it will help a lot of people out. Looking forward to your next video keep up the great work and stay safe out there.Cheers DC.

I really appreciate your comment and your blunt honesty. Thanks so much for sticking with me. I prefer to make videos that I (and other like-minded individuals) would want to watch. It's a real balancing act though when it comes to ads, reviews and sponsorships. Like many other popular KZread channels, the inbox is filled with offers for products and partnerships. So you have to be selective and "just say no thanks" for 99% of them. Nevertheless, there is usually some kind of educational take-a-way even for those who may never do that specific project or buy that piece of equipment. You're not alone though. Many I've spoken to feel the same way. Over the years, I have stopped watching many channels for a number of reasons. Perhaps my interests have evolved beyond vlogging. Thanks for keeping it real :)

I've always never had an ATS and still do. Good info to know encase I never not have one.

Something you didn't mention in this video, is that the frequency of an unloaded generator will vary, usually a little high, until the generator is loaded, at which time the generator frequency settles right down to 60 (or 50 if you are in Europe). This is entirely normal and desirable. This was a great tutorial, as usual, though. I'm really happy you mentioned torque settings. Torque settings, and the importance of torque, are not well-understood by a lot of people. Could you do a tutorial on that subject?

Excellent Brian! I replaced mine with the recent Lithium/Victron Inverter project. I noted the recommendations on torquing stranded cables 2 to 3 times. I was surprised at how after each snugging down of the screw, I’d wiggle the cable a tad and then retorque it. It would snug down further on the first 2 or three times I did that. Avoids poor connections that lead to heat and possible issues down the road. Carry on good sir!! 😊

Great video, thanks for sharing. We had the same issue in May this year, it would work for a few minutes while it was cold, then kick out and no power until it cooled off again. We were boondocking, so we were on generator power and no way to get the transfer switch, so I just pulled the cable and put a socket on it and pluged the shore line cable into this new generator socket. It worked until I was able to get a new transfer case. I think I caused the failure buy putting a storage box in the bay, not enough air circulating around, so I think it burned up. I still store a box in there on move day, but take it out as soon as we are setup.

Transfer switches vary in price from $150ish and up. There's a link in the video description that will list several. You can see the price difference. The layout usually varies from one unit to another. So it's usually a good idea to find an exact replacement to minimize any need for re-cabling it. Good idea keeping those turn signals oiled up :)

My ATS defaults to the generator side so if the internal switch fails I'll only get power from the generator. One evening, after pulling into a remote USFS campground that is exactly what happened. No power when plugged in (EMS said there was power) but power on generator. Turns out one of the small wires from the ATS circuit board had come loose. Once that was reattached everything worked great. Only took 2 hours to solve that one!

Did you do a video on integrating a solar power from inverter to a current existing RV distribution box? If the old unit is a converter box to run AC appliances and dc consumables, how would you fit the Victron solar/ battery power into the unit? Do you bypass and skip the old unit or hook it in where the solar power goes into the RV power panel?

@RVwithTito

9 ай бұрын

It depends on your inverter. If your inverter is also a charger, then you don't need the converter anymore. Here's a video about the inverter (kzread.info/dash/bejne/n5eqppiNhrPccZc.htmlsi=mB3svrPFw1zMNcqw) and here's one that talks about the battery hookup (kzread.info/dash/bejne/oqKL0sSgnajOhrQ.htmlsi=8AiKBkIZ6lUuOmfs&t=283)

Can you explain why some say you need to replace your ATS with a BIM when you go solar ????

I don't know that it matters, but did you notice your ATS is wired against standard? Normally Black is L1 and Red is L2. I don't think it matters and it looks like all three lines going into and coming out of your ATS were all wired the same, but I recently looked this up wiring my Multiplus in so I noticed it when you cracked the ATS open. The lines inside for the ATS works were wired to the standard.

@RVwithTito

Good eye. You noticed :) You're right. Per NEC, black is L1 and red is L2, but it really doesn't matter as long as you're consistent and your legs are balanced. I do plan to swap them though. Originally, my RV electrical panel was wired with red on L1 for some reason. So I wired my Multiplus the same...then the ATS. Next time I crack my Multiplus open I'll get it done. I should have probably done that prior to this video though :P

The neutral wasn't swapped. There should not be a ground/neutral bond in the RV which is wired like a sub-panel.

It's not a simple answer/solution unfortunately. I'm assuming it's not a hybrid inverter.

In the second scenario you must switch off or disable the charger (very important).

But as you say, I have to remember to throw the breaker on my converter/charger.
