Thanks Mike. Sometimes there is no solution for isolated data connections and you can only use what you get on the market.

@johanneslode2006 8 месяцев назад

Do not forget to connect the GND line, especially on an isolated CAN interface board, otherwise you might run into the same problems as before from floating potentials damaging your IO stages. Differential signaling does not mean GND free signaling. Pull your isolated GND plane of the IO board to a known potential. I had enough problems of this kind to solve as an hardware development engineer in industrial metering industries.

@ciano5475 8 месяцев назад

I was commenting the same when I saw the two wire.

@Ether_Void 8 месяцев назад

Usually it works on on isolated stages since the GND potential will be defined since most transceiver ICs have protection diodes which will pull the GND potential to the lowest pin and the current required to do so is tiny. Sometimes there is even a external resistor network that usually bias the CAN_H and CAN_L lines to a reference point of the transceiver but would probably also create a defined GND potential from the incoming signal if it weren't connected. (It's far from ideal but it usually works when capacitance to the non-isolated power rails is low enough) Since the previous CAN hat however wasn't isolated this won't work. In an ideal case the current will be low the diodes will use the CAN_L line as a sort of ground, but even in this case while there won't be any damage due all benefits of the differential signal are lost and noise will interfere with communication. In the worst case as you mentioned it will damage IO stages. PS: In the last video about the CAN Hat at the end he actually said "You most likely don't need ground". Which is of course a wrong assumption to make. I think people mix "quasi/semi-differential" (like CAN, RS485, etc.) with real differential signaling like in Ethernet (where the reference is decoupled via magnetics/transformers).

@johanneslode2006 8 месяцев назад

@@Ether_Void well explained, thank you 🙂!! We engineers have already built in a lot of safety nets so that the shit works well even under adverse conditions 😎. Hopefully noone takes those technical safety nets as a valid excuse to leave the GND connection open, just because it might work. Modern people are always so careless because all the modern safety nets always catch them when they fall off the thightrope. Then they use a lawyer to sue anyone who didnt tell them that you can hurt yourself when you fall off the tightrope.

@OffGridGarageAustralia 8 месяцев назад

No ground connection on either side and it seems to work without issues since the installation. I'll keep this in mind if I run into issues.

@Ether_Void 8 месяцев назад

@@OffGridGarageAustralia As mentioned (in my rather convoluted and long comment) this is somewhat expected when the driver is isolated since the bias circuit and/or protection diodes of the driver take care of that. But I still think the issues with the previous CAN-Hat that wasn't isolated came from a missing ground connection so it depends on too many other factors if the CAN signals are in a voltage range that the driver can still detect.

Hi Andy! The manufacturer of the charge controller (Not Victron) says that I cannot connect two similar charge controllers in parallel so that they receive power from the same wire that comes from the solar panels, but I can connect them both in parallel to charge the same battery, as long as both controllers get their own power from different circuits. But: No one has yet explained to me why they must not be sharing the same circuit, although I have asked the experts. This idea came about because I already have a charge controller, the capacity of which may not be enough for the power produced by the current panel when the sun is shining on a cloudless, frosty day in winter and when there is snow on the ground everywhere reflecting the extra sunlight. The charge controller manufacturer said that the controller is damaged by too much current from the panels, in addition to only being able to withstand a certain voltage. So I originally thought that by getting another similar charge controller I would fix it: One pair of wires from the solar panels 60 meters away - I share it for both charge controllers to the "PV" terminal and take power from them by connecting both "BATTERY" terminals and take them to the battery via a suitable fuse. I wouldn't want to uselessly divide the panels into two circuits and then spend money on two wires (+/-) (+/-), because even one pair can withstand the current coming from the panels. Maybe You Andy will check out this issue... Thank you!

@OffGridGarageAustralia 8 месяцев назад

You can connect as many solar charge controllers to your battery as you like. Each solar charge controller needs its own separate array of solar panels.

@@MR-ub6sq It's in the name MPPT - Maximum Power Point Tracking. The controller drives the panels at their max power point depending on light conditions. Another controller at the same panels would interfere with the first controller and they start fighting.

@MR-ub6sq 8 месяцев назад

@@OffGridGarageAustralia Thank you Andy. You have the opportunity to test the nature of this "fight" because you have multiple Victrons of the same type. Connect two Victrons in parallel to "fight" for power from the same panel array. Do it and we can learn what it's really like! When I ask Victron's European headquarters, they pass my question to the importer, who can't explain it... Since I'm not very good at English (I use google translator all the time) I don't really know how the MPPT controller "drives" the panels - as you wrote. My sense says that the panels do what they do regardless of the controller, but the controller makes the current coming from the panels as large as possible, lowering the charging voltage suitable for the battery. My imagination says that I want to have a charge controller that always drives the panels directly towards the sun :)

Hi Andy, hope you had an enjoyable Christmas and wishing you a very happy 2024. Loosely related to the double can board, how would the Victron inverter / cerbo GX cope if 2 brands of BMS were connected via can to the cerbo. Currently have pylontech batteries but planning on adding more capacity and thinking of getting my own cells and separate bms to add to existing system?

@OffGridGarageAustralia 8 месяцев назад

Happy New Year! That will most likely not work. You can only connect one BMS to the Cerbo/Pi. If you have several batteries with their own BMS each, they need to communicate all data to the master BMS which aggregates the data and sends it to the Cerbo. So, all BMS need to be the same brand and compatible to each other. Be aware that Pylontech uses a 15s battery design, not 16s as all other batteries.

We've upgraded the batteries in our BMW i3's and I have rebuild the old 60Ah/22kWh packs to 12S8P and equiped each pack with a master BMS, which uses the OEM slave BMS modules on the battery modules. The SimpBMS supports Victron CAN connections. Unfortunatly I need two SimpBMS's, one for each pack, and they provide the same CAN ID - hence the newer Venus mixes them up, just like in your video from about a year ago..

Andy I have a 200 amp jk BMS and it's on a 840 ah 24 volt battery. It's 3p8s. I'd like 2 more BMS but I don't know if they can be ran 3 in parallel

@OffGridGarageAustralia 8 месяцев назад

Do you want to split your parallel batteries?

@OffGridGarageAustralia 8 месяцев назад

Each battery needs its own BMS. Then you parallel the batteries again.

Have you ever tried running with no bms???Cuz I've been doing it for 10 years now and have had no problems you should make a video about that!......lol. Cuz allllll this stuff is a big fat gimmick unless you start with crappy cells or salvage cells

Nobody should operate lithium batteries without a BMS!

A system with a code that expires after 1 hour is enough to steer me away from that company. That puts Dali in the top again for BMS.

@typxxilps 8 месяцев назад

really, doesn't such thing depend on how often you would need these special rights ? We are not talking about a firmware update afaik but a special configuration for andi . I am not sure in which world you are living but usually the manufacturers of all such devices like central heatings, big acs and solar power are simply protecting their products and allow only installers to work on them with installer codes. That is a usual business practice in the western world at least. Happens also for inverters where you can not change major things without such code your installer might give you or rather not. This would not be a reason for me to go for a bms and for sure not for a Dali which is upgrading and communicating with inverters how ? Have not heard about that and active balancing with up to 4 A is also not the best, but I know a friend who had lost 2 Dali which needed to be replaced due to faulty or poor soldering and low quality control which meant for him that 25% of his 8 Dali for 8 batteries did not work. Quite a lot. But dali might have improved since 2020 and the first covid year, but they had lost his as their customer due to all the troubles and laziness. He had to use paypal to get the situation solved and later sold all dali after the third suffered a similiar issue with poor soldering cause he did not want to deal with the missing soldering quality every few months or so and went for SEPLOS and JK each supplying 4 batteries and 60 kWh.

My old style JK BMS forgot it's password, it was a nightmare getting a code that only worked for 30 minutes. What they fail to realise is the whole world doesn't run on Chinese time, so it was either the middle of the night hear in the UK when they were in their offoce, or I had to be at work, why they couldn't build a reset switch or jumper into the BMS I don't know!

@zingzing6550 8 месяцев назад

@@typxxilps If I bought the thing I want and need full control. Anything less is a rip off. What happens if they go belly up? Also...it's not their products if I bought and paid for it. It is mine. Everything you say just underscores the reasons why not to buy from manufacturers the use that type of idiotic system administration. None of my products have such solutions, and no product with such solutions or hindrance will enter my homes or systems.
