Awesome video. I'm building an RV and was just at the stage of adding the solar disconnect. Learned a LOT with this and saved me a lot of hassle down the road, and possibly a disaster as well as I was about to use one of the switches you advised to never use here.

Hi Nate, very helpful video as usual. Most other video simply recommend one of the other breakers that you suggested not be used due to voltage issues which I appreciate. One question I had was where do you get that black backer board for install? I dont see it on your parts list. Thanks

LOL, that DC-DC charger just wasn't going to let you connect it instead of the MPPT charge controller! Love it. While the NEC doesn't _technically_ apply to off-grid RV installations, they are, nonetheless best practices. As such, I follow code as much as possible and practical. This is to say that not everyone does (follow code, that is). I just finished up redoing what what supposed to have been a completed off-grid solar system in a 1969 Airstream renovation. The original work was performed by an electrical engineer. When I got involved, there was one 100V/50A MPPT charge controller for the permanent roof-mount array *and* an auxiliary portable array! A 1-1+2-2 battery switch, rated for 32V max, was installed to connect/disconnect arrays. The 3S 100W panels produced ~65V nominal @ ~6A. This was all connected with 4AWG wire! What a mess. To correct this, I installed a second, smaller MPPT SCC for the portable PV array. I eliminated the battery selector switch, and installed a non-polarized, dual pole, DC breaker in an enclosure. I did the same between the roof-mount PV array and the first MPPT SCC. I also transitioned the wire down from 4AWG to 10AWG. Not only is the 10AWG more than adequate for the current, but the silicone insulation made cable management so much easier. A 30A shore power input was also previously installed...with zero protection between it and a MultiPlus worth well over $2K! I installed a non-polarized, dual pole, AC breaker on this line, as well, as one can never be certain what's coming off the post in many campgrounds. Unbeknownst to me, my client then took the trailer to the largest solar dealer in Atlanta. He paid them $500 to check my work. They assured him that everything was correct. However, they also told him that it was "overkill." What! All I can say is, "Buyer beware." Someone also told my client that the PV array must be grounded to the trailer chassis. Nothing could be further from correct. One should only ever consider grounding the frames of the PV array. Never the conductors! That's what the PV isolation breaker highlighted in this video is for! As always, Nate, great work!

I understand you need the breaker for a home system that is connected to the grid, ( I have a grid tie system) but I have not heard of having to follow code on a camper or off grid cabin. I put one in on the system that I installed on my toy hauler, but it was just for my own safety so I can disconnect it when I want to work on it

Ultimately, nobody is going to be checking our work on a camper. There are no inspectors for this. My goal is to teach the safest way I possibly can for this stuff and if people want to opt-out of particular things that they feel not important.. that's their prerogative.

So if I wanted the breaker to act in the same way as a fuse would I choose a breaker slightly bigger than the short circuit amperage of my single panel. If that makes sense. Excellent video by the way.

Hi Nate Loving your videos - thanks. I have a question about wiring the switch up. I saw a video saying that you have the have the pos and neg on certain sides otherwise the unit bursts in to flames when turned off? Obviously + to + and - to -, but does it matter which side of the unit is used? mine has a large N on one of the terminals on the right hand side so guess that would be the neg connection, but does it really matter if i run the positive down the right hand side of the switch or the left hand side of the switch?? Hope that makes sense? many thanks

I built out my electrical system according to the custom design you created for me and it works fantastic. I'm finally adding a 120W suitcase solar panel and the plan doesn't show a DC disconnect switch. Do I need one if I only plan to occasionally connect the panel to the MPPT charge controller? The disconnect would be the MC4 connectors between panel and charger controller.

@EXPLORISTlife

I'd say it's fine without for portable panels. You can 'turn the panels off' by flipping them over face-down and then when you disconnect both MC4 connectors; that is effectively disconnecting both the positive and negative conductors.

Nate, great video. I have question I've been trying to figure out the answer for. I have 100 W panel installed on my campervan's roof and now I want a flexible addon system so I've bought a foldable 120 W panel that I'm pulling out every now and then to increase the solar power charging. I want it wired to the same Victron Smart Solar 75/15, all good there.. but! I want a flexible way of connecting and disconnecting the foldable panel. I'm thinking a socket and a plug but also a switch, either for both panels or only for the foldable one so I can flip the switch to disconnect, plug in the foldable panel, then flip the switch again to connect the panel to the Victron Smart Solar. Is that a viable and for the equipment safe way of handling my desired use case ? I realise now that you say that the voltage maximum is an issue for my idea.. If I use a disconnect maybe I'll mess it up by maybe flipping it on and off every day for a couple of times a day for a couple of weeks straight, they're not designed for that use as I've heard. Best regards Magnus from Sweden.

I purchased this breaker box and 63 amp breaker from the product list on from your video. I see that the box fits two breakers. Is there a reason that I should not use a second identical breaker for the shut off and protection for my Orion dc to dc charger? 8 Awg for panel 6 Awg for Orion are the cable sizes I’m using. Thank you for all you do

I purchased two of these breakers from your link a while back. My plan was to use the second one in the same enclosure as a shut off for my Orion dc to dc charger. I was hoping that the 63 amp rating would offer redundant over current protection for my 6 awg cable coming from the van bus bar under the drivers seat. Is this an ok application for the breaker?

Hi Nate, this is a great video like so many of yours. We live in Australia and I have a question, our caravan has a 1000 watts of solar on the roof and is connected to a Victron 250/70 mmpt solar controller. Our system hasn’t been installed with a solar disconnect, what size would you suggest. Regards Brian

Hi, this is such a great video! I’m wanting to make a quick PV disconnect inline switch for a tiny, camping DIY solar generator / power box using a 12v Renogy 10A solar controller, connect to a 12 watt .5A solar panel and a 7Ah NPP SLA battery. It’s purpose it so power small devices for a tent. There are situations where it would be helpful to shut down the solar panel current coming to the controller while working on the battery or removing the battery. The controller instructions however say not unplug the panel before the battery so I’m guessing a regular inline SAE switch cable is not advised? If so, do you have any smaller current 12v switches you can recommend? Are any of the ones you pointed to in this video (that do not work for larger, gov regulated systems) good for my set up? Thanks so much!

Excellent info you have provided! Would it be possible to combine the breaker shutoff feature and also be able to satisfy the fuse requirements on that side of the controller? Say one needed a 30amp fuse on the positive side between the controller and panels, couldn't the shutoff breaker be rated at 30amp, allowing the breaker to do a dual duty? An older video but perhaps someone out there has a thought on this...thx

Hi. According to your explanation: 63amps dc breaker >250v fits all solar systems between pv and solar inverter. What about the amp size of dc circuit breaker between the inverter and the batteries? And the ac circuit breaker between in and out ac current?

Is there a breaker panel that takes and sends out three pairs of md4 connectors for multiple panel groups connecting to the new Victron smart solar 150/85 or bigger controllers...I'd rather use dedicated cables for each group and not seeing why I don't stick with the BogueRV prepared cables... new to all things solar though.

I have a combiner box outside by the panels in a weather proof box with 3 - 15amp breakers will this be ok and not have to be in the house.

Just finished watching, great as always. My van is in the design phase and I am trying to physically locate this switch where it would be easy locate such that it is immediately accessible to emergency services in the event of an MVA or similar emergency. My thought is to place it in an electrical box accessible from the out side where the shore power enters the van. Passenger side just behind the rear axle. The electrical room is above the rear axle in the rear garage and accessible for maintenance by lifting the step to the twin bed above the garage. The solar shut off box and accompanying door will be a pain to fabricate but provides some security and yet quick accessibility and visible to fire fighters and EMS.

I was a career firefighter before this whole KZread thing, so I may be able to shed some light on that issue... but firefighters/EMS aren't going to be looking for a solar disconnect switch in an RV during an MVA. Maybe in the future, as more electric cars and solar powered campers become a thing, firefighters will be trained more on this kind of stuff, but even If I, as a firefighter, saw a solar disconnect switch; it's highly unlikely I would touch it as I wouldn't know for 100% what it does or what other 'downstream' hazards that flipping that switch may do. If, in the event that the body of the vehicle was energized... We would call the local utility company to have a lineman come out and get recommendations on how to proceed safely. Basically... do it if you want, for sure... but I wouldn't stress about it.

As Nate mentions, first responders aren't likely to know to look for this disconnect, or use it in the event of an emergency. The primary reason for this isolation switch/breaker is to allow you to safely work on your electrical system by safely disconnecting a source of live DC current even in low light conditions.

Question. Can I use 10 awg PV wire for other power uses inside the RV, as I've a lot of it left over. Thanks for any help.

I'm about to add solar disconnect breakers to my travel trailer, I have roof mounted panels as well as a thru wall plug for portable. I know I will add the disconnect between panels and controller for the roof mounted, but I also want to add one for the portable circuit. My portable has the controller attached to the array. Do I need to move that controller to between the battery and the disconnect or is it OK to leave the controller where it is (panel>controller>thru wall plug>disconnect>battery) I was thinking in this configuration the thru wall plug become an alternate 12V source with the disconnect to turn it off.

@@EXPLORISTlife Thanks, I'll do that.

I have a solar generator in my house that will be hooked to three 400 watt solar panels wired in series. Together the three panels will generate 150 volts DC at 9 amps. It looks like the breakers you are using will work with this setup. Are there any similar breakers that can be used outside. I would prefer to mount the breakers at the panels on my solar ground mount rather than inside the house.

One question, you said it is a regulation to have a solar breaker, so why does Jayco and multiple more caravan builders don’t install it? All that it is on the incoming positive wire is a 30a fuse.

Our inverter has 2 mppt input each can take 11A . but our PV Panel produces 17.33A. Can we use Y connector to divide current and input 8.665A per mppt input?

Can I use 2 single pole 10amp DC breakers side by side coming from just a single 100 watt solar panel, then to 10amp controller just for using as switches to disconnect + and - from solar panels......Or just put the breaker on the positive from solar panel. Cheers, great video's! Jason.

You ***can*** do whatever you like. I've provided the proper information; now it's up to you to decide what you actually want to do. 👍🙂

Hey how are you doing? First of all, I like to see how you explain all your videos . I'm starting been interesting in solar panel systems & I built one in my house as a fun time. Now, I bought a solar controller similar to a Panda one or something like that; & I have noticed that wattages/amps are fluctuating too much. My system is built with: 4 panels of 100ah 12v in series/parallel making 24v system, solar controller 60amps, inverter 3500w, now I'm using 4awg wires for batteries, 10awg solar controller/panels, 8awg controller/batteries, also, & maybe this is the reason of fluctuating 4 car batteries. Could you give some tips about why wattages/amps are fluctuating too much.? thanks in advance.

Hey, Wilfredo Hernandez! I appreciate you taking the time to ask your question, but unfortunately, I don't have enough info about your specific question to provide an accurate answer, but here is a playlist that, if you watch all of the videos start-to-finish (and take notes 😉), you'll have a REALLY good idea of how to design a solar array which may help with your troubleshooting: kzread.info/dash/bejne/fJ-W1Zpto6Wuo8o.html

I switched to that double pole last summer because you mentioned it in another video. Thanks for the explanation as to why. It sounds like that was an update in the 2020 code so there's probably lots of incorrectly wired PV systems on RVs. I had the Blue sea systems circuit breaker and my series/parallel was around 44v so I guess it was ok but I had tunnel vision looking at the amperage and not the max voltage. Thanks for explaining this in detail, great job and thank you 😁👍

Yeah, I've made that mistake in the past as well before I really dove into doing this stuff (and teaching it) properly.

Nate Jim Partlow here. I purchased the DC solar disconnect switch for my solar install . I also see that you have used a solar disconnect breaker and din rail. Which is best or are both needed? In all your wiring diagrams you use one or the other, is it just a change in product and serves the same purpose. Thanks
