- I finally show what is in the mystery box. It is very exciting stuff what Ed from Off-Grid Power Systems has send me. UNBELIEVABLE what he put in this parcel! So, I give him a nice plug for that! Thanks a lot, Ed!
We are continuing working on the new PowerWall 2.1 and install some cable ducts for the cable runs. The Victron Cerbo GX is certainly a fantastic device with a lot, I mean A LOT of communication ports all around. We quickly mount this on the new PowerWall as well. I need a new name for the Cerbo to connect to the Victron VRM, so please leave any suggestions down in the comment section.
I also have some... aeh not so good news, I guess... from Seplos again. I really don't understand the philosophy about their product design for this new BMS 🤷♂️

Andy, please check which production number the Cerbo has. The most recent one have a quality issue and the power input and can only stand 12 and 24 Volts but NOT 48V, except you solder a capacitor over the DC input! Quite a shame for a quality company like Victron. I bought one and burned it, now I know why......
I know... that's now circling for a while out there. Thanks for reminding everyone.
Andy please straighten your Cerbo GX the crookedness is triggering my OCD. 😁
I came to the comments to see if anyone else had said this, i agree! This is off grid garage not the wonky grid garage! 🤣
I'm really surprised how many people picked up on that. 😂
you deserve more. you're our unofficial lab. I don't buy things before I check your verdict.. I honestly think you should make a "wishlist" then put all the things you would love to have. most of us are happy to get them for you.
True, but what is the lab for? You might think its about batteries, but I have a feeling that is just a cover story, its actually about beer 🙂
It is all about the beer and sharing my experience...😂
I already have most of the equipment now but yeah, I still have some items on my list but we will get there over time.
If you put 48v into it, it will break it. See the Victron forum for more info.
Name it Off-grid smoked! 😊
Thanks for that!
@@HolgerNestmann i was lucky to feed only 12V to it even my bank is 48v. Saved a lot of money with that.
@@tujuprojects Yeah, I didn‘t know and it is hanging off the 48V System right now on my remote property. If I cant find such a capacitor I will feed 12v to it too
@@HolgerNestmann we should be entitled for refund. Some moneny back or discounts from coming purchases.
Just to say somethime Bad about your video: the Cerbo dont look like it is leveled :) .... Andy .... I Love your videos and presentation of technical things. You are my role model for my Videos but i will never be able to do it that perfekt.
Just one Thing: there is a series of cerbos which will break If powered by 48V +. There is a list of serial numbers which are effected dircectly from Victron. You should check that before powering in the first time.
Thanks a lot, Jens, much appreciate your kind words.
Yeah, I know about the power issue with the Cerbos. Mine is in this range as well...
Caution with the Cerbo GX as l think the HDMI metal socket is battery negative. My system developed a positive earth fault, and I blew up my first Cerbo when I added a mains powered LCD monitor which earthed the HDMI lead screening.
great heads up!!! Had it connected to a big screen tv with no issue temporarily but will think again after hearing this! Cheers
Then there should be a large warning somewhere.
Although also possible theres a short in the hdmi-usb cable
@@davidmills2266 No I had a full earth short to my positive Aux supply which was Breaker'd at 6A. So, the 13A UK socket earth was at +25V potential DC, through the LCD monitor, through the HDMI lead and big spark when the earth pin touched the socket and no Cerbo GX anymore. So, I assumed the Cerbo GX HDMI socket shield is at -VE potential?
Hey Andy, thanks for keeping us on the inside. Cheers my friend!
Awesome as always Andy.
Ed Jones truly wowed me.

“Vicky,” the off grid power wall
Name: Off Grid Garage Cerbo GX. Another great video Andy and a very nice new toy to play with.
Waited ages for a com cable for my 3 x Seplos “Suntorque” 5kw batteries, it arrived, and i still cant get communication with the BMS’s. After 6 months of ginning around I have got them working ok, sort of, but they have been a real hassle to get going right. I bumped the voltage a little (56v) from 55.2v and they jumped from around 70% to 98-100% soon after, so I am guessing the SOC reporting is actually triggered by voltage, but that is a big jump from 70-100%, hopefully this has reset the BMS and it will work better now & Ill drop off the voltage again. Love ur vids & look forward them. Cheers
Thanks for sharing, Evan. I hope Seplos can get it sorted as I have the JK-BMSes on my fingertips and ready to go. I won't be mucking around much with the Seplos any more if they don't work.
Thank you Off Grid Power Systems for supporting Andy !
Honestly, I can't understand, that a Fuse, which needs tools, to be exchanged or disconnected is the same, al a breaker
Pls help
Andy, just name the Cerbo GX "Off-Grid Garage GX" for "Garage Xtended" 😉
You have to call the power wall ( Ed Jones) 😁😁

Please do not transform this channel in Victron channel!
Now Cerbo, next Pylontech. You’re slowly getting there.
Hahaha, nah, I probably won't go down that route...
15:19 - finally the Cerbo GX my lovely grown up guy toy.
@Off-Grid Garage: a new Name for the Cerbo GX -> Einstein Off-Grid Garage
Dutch price for the Cerbo GX is 350,- Euro and it is worth it. We / I use it in every customer installation.
I would definitely use it in customer installations as well. No way you would setup a Raspi just to save $100
Call it Rat Face. I kid! Why would you call it anything but the "Off Grid Garage Cerbo GX"? I agree with Evan. Could even drop the "GX".
Also I agree., life's too short I'd love to see you replace those Siphlic BMSes with some JKs.
Thanks Keith.
Hi Andy, why not name it the "ED-System"?
(cerbo off grid garage) . how about it Andy
Everything should just be called Peter..... and if there is any confusion, just append the next available number... 😂
Hahaha, imagine that...😂
If you want to save money on the BMS-CAN/A cable you can just link add 3 link cables (+/-/GND) to a cheap RJ45 eithernet 2 port socket and then just use chap ethernet cables.
Yeah, I was going to make my own cable, just cut one in the middle and solder the 3 pins we need. Victron has the pin-out on their website.
Name: Offgrid Garage vici (Vici for victron)
Why don’t you try a Batrium BMS, it can manage many cluster together. It would be interesting
You are the best 👍🏻 weiter so
Thanks Mario.
I'm in contact with Batrium for a while but wanted to test consumer grade BMS. Not many people will buy the (overpriced) Batrium solution.
May I suggest using the touch50 or touch70 screens? 2 reasons, 1: it can be powered directly from the cerbo by the usb port next to the hdmi port, 2: it is touch sensitive. This will stop any funny earthing issues by using externaly powered moniters.
Congrats on the cerbo,I had to ditch my pi because of no canhat availability in my area, I got hold of a venus gx.
Just a quick tip for the CAN setup, my batteries did not get detected, the reason was the incorrect can settings, my gx was on "VE.Can & Lynx Ion BMS (250kbit/s).
It should be CAN-bus BMS (500 kbit/s).
Access this from: Settings - Services - VE.Can port - CAN-bus profile. Also the RJ45 is not a straight or cross (A-B) configuration, so just make sure you get the correct config for VE.Can and your battery(s)...
Good luck Andy, lots of decisions.
Touch 70! Bigger is always better!
Fun fact: There's 7" Touch screens available for a fraction of the price, they're made for Raspis. About 80€ instead of 350... Although I haven't gotten the touch functionality working on mine yet, but it might just be because I don't have a micro usb cable with data pins...
Do you perhaps have a link?
Thank you.
I like the wireless display far more than having a HDMI connection. I'm using my old tablet for that reason. I also use the remote console on my mobile phone and computer inside the house.
Yeah, the CAN needs to be on 500kB/s for the Seplos battery for example.
Now you have the Cerbo GX are you going to have to get a new set of VE-direct cable , or can you still use the VE-direct to usb cables ?
Because to me the Cerbo GX used a different set of cable which are cheaper and doesn't look like there is any electronics between the 2 VE-direct plugs ?.
I have a Victron SmartSolar charge controller 250 | 85 an I intend to buy a LiFePO4 battery. Is there any danger for this charger if the BMS of the battery disconnects the battery and the charger is still connected to the solar panels array?
I have tested this many times with my controllers and disconnected the battery under full charge. The Victron controllers can handle that and go into absorption mode/voltage, still supplying power to your loads if they can keep up.
Change the BMS to JK BMS, I had a problem with one of my JK BMS and there service was fantastic 👍 to JK BMS.
Thanks for sharing. Which shop did you deal with?
Ruuvi is great - I have them all over the place. Finnish company by the way ;)
You have them connected to your Pi or Cerbo?
@@OffGridGarageAustralia Pi. I don't use a Cerbo.
Give me a breaker over a fuse, call it a personal preference. Combined switch i and high interrupt capacity fusing.
Yes, I'm with you on that. However fuses have certain advantages in some cases...
'The Off Grid Garage Blue Wall'
OGGA Blue Wall?
Ok, but how does the raspberry pi communicate with the charge controller, shunt, inverters?
That all works through the Victron system using DVCC for example.
Heya, oh wouw you have a very good community here. off grid garage ed's or something
Yes, the community is the best!
Off Grid Blue Garage - for the fact that its more Victron heavy than your other ;)
Thank you for your suggestion.
First thing,love the secret beer fridge.
It's hidden behind the shelf 😂
Where do you get your cable run covers the. Cable ways I need a way to cover my conked without costing an arm and a leg and I like the plastic run ways
I bought them at a local electrical store but you can also get them online from eBay and Amazon.
Hi Andy, I would name it "Off Grid Garage GX".
Btw your Cerbo GX is mounted "krumm" 🤔.
Cheers, Henry 🍻
Hi Andy. I'd be very interested if you do some testing with Venus OS Large on the Cerbo GX. The Node Red functionality looks useful. "Off-grid Spat Cooler"
Peter ! You should call it Peter !
Name it; Off grid garage 2.1

Hello andy !!!!please please please ,help me. I bought the jk bms JK RESS Active Balance BMS PB2A16S20P - (7S - 16S) - 200A - LiFePO4 / Li-Ion / LTO , and i dont know what cable to buy for the cerbo
Finally something to watch
How about the Off-Grid Garage Peter for the name lol
Hahaha, great...
I would suggest "Off Grid GarageX". BTW, with actual Raspberry Pi prices and unobtanium availability, the Cerbo GX is starting to be more appealing, also considering that you don't have to buy usb to victron adapters.
Great suggestion, I like it.
I've got a Raspi on back order for 7 months now, still no ETA. so this is not an option any more, I guess.
Victron still recommends the VE.Direct to RS232 adapters due to the isolation of the circuits when connecting to other gear.
New name “Off-Grid Garage-GX” simple.
Thank you, I'll put this on the list.

Off-grid garage dev
Hi Andy love the channel but sadly for me i cant afford cerbo GX at over $700nz ill keep going with my little raspberry pi at $100nz as it work very well.
Yeah, It is a lot of money for this device. The Pi is doing fine and will keep working in my main production system.
I got the Cerbo mainly for testing purposes in regards to the communication side of things. That may be the only real advantage. Everything else can be realised with the Pi and a bit of work, programming and scripting.
Gotta order me another Cerbo..... one I have now is doing fine, but system is expanding.........
Good video, is there an Chinese alternative for the Victron USB to RS485 cable to connect ET112 to Cerbo GX?
Wow, $100 for a $5 fuse. Must be pure gold from Victron.
No, Platinum. 😉
There are huge differences in specifications for fuses and the higher the voltage and higher the interrupt capacity the more expensive they get.

Another fantastic vid Andy, What style. You could name the new setup a thingamebob!!
Off-Grid Garage Victron
Thank you.
Do NOT connect 48V straight into that Cerbo. Based on the 3 that I have killed they are not very robust when connected to a large 48V LiFePO4 battery. There's a Victron update which specifies connection of an electrolytic capacitor close to the device. I just convert down to 12V instead
Wonder what the issue is with your setup since I have mine connected directly to the 48V battery bus.
No problems running on 24v here....
Do you have a link to the info from Victron? Haven't seen anything about that on Victron Professional. Have one running on a 48V system for 6 mon now.
@@tx75e94 Cerbo GX power supply issue in 48V systems
Technote August 2022 - v5
@@davidb.5544 Affected model/serial numbers
Model: Cerbo GX, part number BPP900450100
Serial numbers: HQ2201xxxxx up and including HQ2220xxxx.
I've had them running at 48V, but it's about a 30% chance of it blowing up on the next power cycle.
The Cerbo GX is so so so easy to use and set up compared to the RasPi, you'll love it. I'm about to put one in my van (yes I finally bit the bullet and went full Victron).
And the Ruuvitags are something a customer of mine installs all the time with my batteries. he often puts one in the fridge, one in the freezer, one in the battery/inverter compartment of a caravan, and sometimes even more. I've just convinced Solar4RV's (a shop down here in Melbourne) to stock them, so now you know where you can order more when you want to monitor each BMS as well as the SPAT fridge. ;)
I'm guessing that would be Matt at Extreme?
Thanks a lot Paul. I'll have a look what the prices are with them.

Hey, I know that guy. 😊

Nice!
I've a stack of boxes of containing the exact same system ready to build, right down to the Seplos Mason 280AH (Although with the 200A BMS fortunately). This series of videos could not have come at a better time. Thank you. I also have a JK BMS en route too. Would you use both BMS' in the Mason or only one? I like the idea of the JK's active balancing, yet the Seplos is actually designed to fit in the case and has the LCD. If only one can be used it's a dlllema!
Yes. I agree with everything @Ben C Naylor has said. If I may add to that... Definitely DO NOT try and use two BMS's on one battery, that is looking for a heap of trouble and a world of hurt when it DOES go wrong, and believe me..... It will inevitably go wrong.... Ask me how I know this? 😁 Secondly, JK does have screens, you would need to "customize" the enclosure for it to fit. If I am not mistaken, Andy has one with the display? I stand to be corrected though. Next, If you are doing this to get CAN communication you need to make sure that your receiving devices can interpret the CAN language used by the JK stuff. If I were you, I would just make sure to get the same model of BMS make sure it supports native CAN and RS485 and use that.... It will be the least amount of trouble. Hope this helps. Good luck!
@@GapRecordingsNamibia @Ben C Naylor Thanks for the info. In hindsight I should have just bought the NEEEEY Active Balancer instead. On the plus side I've a back up BMS I suppose. I will certainly check out the screens.

Thanks Andy, (Off-Grid Garage Ed GX)
In my opinion if SEPLOS can't / wont make it work, then those battery cases are useless or at least way to expensive to be considered for any DIY project that involves more than 1 battery pack. Hope many people will watch your video series, so to make an informed decision.
Yes, that's my opinion as well. Far too expensive for a metal box to house your batteries. Let's see, if they can make it work...

Go for it Andy, replace the Seplos BMS in the case with a JKBMS. As a fellow Seplos 280DIY owner I'd like to see a BMS swap out
I'll wait for their replacement BMSes first and if they still don't perform...
You are so funny, Andy 😀😀😀
What have I done now?
Great Andy 😊. No new suggestion because already mentioned: OGG Cerbo GX. In a few months i will start to install my own off grid system in my expedition truck with a Cerbo GX. I learned much from you. Thank you. Keep going on. Greetings from South Tyrol in Italy. 😊

Perfectly straight. I checked three times. Must be the camera angle...😂
@@OffGridGarageAustralia aha ;-)
Question to the pros: do you connect the Cerbo (or Raspberry) directly to the battery or after the BMS? I just had an ugly experience as the BMS triggered the low voltage condition (battery empty) and therefore the Cerbo also switched off. To avoid that I consider to connect the Cerbo directly to the battery. Any experiences in the community? thx for any reply!
I would say, if the BMS has disconnected for any reason, that's it. Something went wrong and you need to look at it anyway and change your design.
Peterwall 🤣 oder Bomben Fest
😂
Thanks for pushing Seplos though! I have rhe exact same issue with 4 x 6.9KW Masons and 3 x 14KW Masons.
Oh wow, I can't believe they still haven't fixed that yet. I assume that only the new BMS can communicate between different batteries. They should replace yours for free.
Welcome to the Cerbo GX world, I really like mine and I think you are going to enjoy your's.
It should not be much difference to the Raspi though...
