So I have 2 of these, and the same thing happened to one of them. This is why I prefer the newer prismatic cell because they are typically in a 4S1P configuration internally for most batteries (unless its a higher capacity one like 400AH). These older renogys have multiple in parallel and in my case there were several dead individual cells and multiple batteries that have horrible self discharge. So I could manually charge each bank to full, and hook the battery up, it would be fully charged and work, but as you drain the battery as a whole I would have a bank that died faster then others, even if i didnt put a load on it for a few weeks. The only way to fix it, is to have 2 batteries in this state and combine good cells that dont have high self discharge, or potentially remove batteries, and drop it down to a 50AH battery. But that comes with its own issues because the BMS protections are for 100AH battery.

Moral of the story: NEVER buy anything from Amazon that has to work.

Craftsman adopted the blue/red for philips/standard on their screwdrivers decades ago. If it works!

Shawn, I also went with the 150/70 (two of them) on my system due to the high volts/amps that it will take before de-rating. My goal is for 2000-3000 watts on the primary controller (to push peak watts of production) and up to 2000 on the second controller.

I have a Transend and have been using a renogy 200 watt suitcase which i plug into the 10amp Furion prewired factory plug. I am using two 100 amp Gel batteries. Its not enough. I want to mount panels on the roof but not sure where to run them down. Where did they run them down on your project? If i run from the inverter to to lugs on the factory switch will that be sufficient and automatically switch when i plug into shore power? Augie

You don’t have to nip the lug is you get fuses that have a round recess in the body.

thanks love watching your vid's

I don’t think I’d want to be a mini split installer.Time consuming.I should be done Monday lol Mega time already into it ! 😮

Love it! Bear is a hoot, but missed neighbor dog Zuki (not sure how to spell it)

The Victron Quattro 2 has an internal transfer switch. I've been looking at getting one.

I see you are installing cooling fans more and more. Can you share more details on what fan you are using and go more into how you are "triggering" turning on the fan. Have you ever used a Ruuvi Tag and the Cerbo to control the fan?? Thanks again, Love you channel

What display are you using?

Great demonstration and observations. Surprisingly, I guessed the scenarios correctly. And, the short run with MPPT showed little benefit, as it should - longer distance and day's worth of output should be a bit higher yet. BTW, you said "blocking" diodes, but they should be bypass diodes (which think you know). Nice capacity setup.

ciao e buongiorno seguo i tuoi video e come te sul mio camper ho istallato tutti i componenti Victron fatta eccezione per l'inverter : pannello da 410W carica batteria Blue Smart IP22 Charger 30Ah, Caricabatterie Non Isolato Orion-Tr Smart 100/30 CC-CC al quale ho aggiunto le ventole per il raffreddamento , Smart Solar MPPT 100/30 , BMV-712 intelligente , tutti collegati con cavo VE-DERECT al CERBO GX. Ora volevo chiederti secondo te come caricare la batteria motore in sosta libera dove non ce la 220v magari sfruttando le tante connessioni del CERBO grazie

I have 2 200ah 12v lithium batteries. I connect in series to make it 24v. Then I plan to buy another 24v 320ah lithium. I will connect this 24v battery to the former 12v banks. Is this ok? All batteries are from the same company. I don’t care one battery charge another battery a little. My concern is it won’t damage other equipments such as charge controller, inverter.

Installed the DiHool switch after watching this video. Had previously installed a Boat Battery Disconnect Switch and a 400a inline terminal and fuse. Tried to make an adjustment to the setup and the terminal post broke off in my hand can't say I would never trust another one in the future. I believe the DiHool might be a lot better option. Love the option if the DiHool trips it can be reset. Thanks for the idea.

my BMV 712 seemed to report empty battery then just stopped working. Have since installed the Victron Lnyx Shunt.

Loved the setup and install. Just curious on how you all tied in the 12v battery to the Orion? Would like to see the connection diagram for that setup. I like having the 12v battery as a buffer to help pickup the slack rather than having the 24/12 converter do all the work.

I guess now you can order the Lynx with bigger holes that dont need to be drilled?

What the temperature of the heat gun to remove the cover? I have 7 bricks from Renogy. and what BMS would you recommend if i wanted to replace it?

I already have one 48v 8000 quattro, one 120/240 100 amp auto transformer and 250/100 victron charge controller and looking to make atleast 50amps 240 in a grand design toy hualer. My question is if I add another 8000 quattro can I use that one auto transformer for both inverters? For redundancy I was hoping to build a system that has 2 of everything needed to keep the power on. 2 charge controllers, 2 panel strings, 2 battery banks, 2 inverters, so I always have atleast half of my desired 50amp 240volt power.

Appreciate it, thanks 👍

15 years ago glued with Sikabond first panels like same amount as this, not on metal but gelcoat surface with aluminun L shape blocks and 5 years ago upgraded bigger panels, but no way to remove old glued blocks, so they are there forever! Just use correct glue and that's it! NEVER EVER DRILL HOLES AS THEY WILL LEAK!

There are literally hundreds of thousands of motorhomes and vans driving through Europe that have their solar panels bonded to the roof without mechanical fasteners, without problems. Simply a matter of using the right adhesive (Sikaflex) and follow the instructions wrt prepping.

So, SOTA is short for Minnesota, eh? I thought it was an acronym for State Of The Art. I always learn something new every time I watch your videos but this lesson was unexpected. Thanks for another great video. 👍

Awesome video thank you!

low light conditions would be nice, i.e winter

Shawn, Have you had any interest in ground-mounted solar for RVs? I've considered assembling frames that would go around the bases of my bus tires (3 per side) as potential secure mounting to prevent theft/wind.

Just RVs...? No crusiers...? Sailboats...?

Unbroken: 185W Broken: 150W

I have one that shattered, but I was able to pour a clear UV resistant epoxy and it runs about 80% of the unbroken panel.

I wasn't going to put much stock in your findings, but when I saw you had a lab coat on, it changed everything!

Question, what did you need to do related to the converter. I’m to a point where I’ve completed the AC connections, I believe I saw that the last breaker is switched off in the video, is that for the converter? Also what gauge did you run to the battery switch, I was going to use 2AWG, OEM gauge was 10. thanks for the video.

I just did this install today. Reasonably simple and straight-forward. But this video gave me the confidence to go ahead and do this install. Getting this 69 yr old man up onto the roof was the more difficult part. 😬 The AC is running off my 3,000 watt generator right now.

Shawn, can you elaborate more (perhaps in a future video) on what you doing for cooling fans to manage heat from enclosed spaces Thanks

Love watching your channel, I've incorporated a lot of your ideas into my small off-grid garage project. Thank You for taking the time to share!

I know those Airstream roofs are tight and those curved roof edges eat up even more space. That extra solar cell looks tucked under the AC which I would guess is gonna cause some shade issues. Have you guys messed with using rails to lift solar cells up and then be able to push them out a bit more to the edges of the roof? (And fit more.) Love the vids!!

I have a ‘22 Airstream Basecamp 20X (ie. Totally different configuration/floor plan, but also 30amp). I have the solar package from the factory (i.e. 2-90 watt Zamp panels). I would like to be able to run the a/c, etc. off grid, similar to what Airstream has done with their Trade Wind model. What would I need and what would it cost detailing parts & labor?

Shawn, have you considered 'white boarding' your systems to show the roof watts and how it translates to the nominal volts/watts and the maximums the charge controllers output? I find it very interesting when understanding/calculating the input and output of the system.

Just had a BULVACK breaker from Amazon almost cost me my home! So not buy these Chinese breakers. I'm learning the hard way for you.

😎

Super duper thanks Shawn for making yourself available on a Saturday to get us set up with a MK3-USB-C to get nephew Brandon's MultiPlus-II + EPOCH 12V 460Ah battery for his Ford Trasit up-and-runnning on the very last day before I had to return to Phoenix. He may have to consult with you later about getting the system "dialed-in" regarding optimum charge settings and maybe replacing his Orion Tr with Orion XS and maybe even getting a Cerbo_GX to take advantage of remote configuration and making use of DVCC. PS here's some trivia: I used to work for this guy in about 1979 when he owned a Dairy Queen on Lake Street in Minneapolis, you may have heard of him :D en.wikipedia.org/wiki/Jack_McCartan

So with a dual battery system at 24V you could get double the wattage right?

I have a 100/30 victron mppt . What about 3 200w panels at open circuit 28v in serious? They will be laying flat.

I dont see a ground from the Lynx to the Multiplus

lower DC arc risk if you keep it under 80Vs and some districts wont require DC ARC Protection on systems with PV lower than 80 Volt with Low Temp Adjustments (120% over VOC) If you dont really have shading issues and a calculator doesnt say you need a higher voltage for the run on say 8AWG wire Parallel will work just fine, you just need MMPT that will handle the AMPS on the PV and get a good quality PV Combiner Box

How you get weather information interface? I have Gui V2 and switched to Beta.

neither will work; diesel, gasoline or gas, or wood, batteries are a joke there,in the cold, maybe for a few led lights, not much more

Have you tried the new and improved Dihool DHM3Z breakers, or still using the DHM1Z breakers?

Great to see your company is busy. Don
