Although you appear to have used good sized cable for DC, it is good practice to not bundle them tight but allow airflow between cables for cooling. Not an issue if cables do not even get warm at Max load. Agree option C, better to keep DC cables short (as there are more Amps) and AC do the longer runs. Love your Frogs, show your garden is a healthy ecosystem. Much better than Cane Toads.

The MPPT terminals with pressure plates are supposed to be user bare wire. NO FERRULES. Actually, they even reduce the contact surface.
@OffGridGarageAustralia
@OffGridGarageAustralia 2 жыл бұрын
The ferrule will flatten when tightening the terminal and spread across the area. Ferrules will make sure that all strands of your cable have contact to the terminal. This may not be the case without ferrule. So I would argue the opposite and say without ferrules the risk of not having all stands making good contact is greater.

@russkubes
@russkubes 2 жыл бұрын
I'm pretty sure he covered this just a few videos ago. Soldering will keep the cables round, which reduces the contact area. Moreover, the solder adds another material between the terminal and cable, which increases resistance, which isn't good in such high current applications.
@CollinBaillie
@CollinBaillie 2 жыл бұрын
@@russkubes I'm pretty sure he covered it also. But people (not me) seem to have missed that. I'm well aware of how bad of an idea it is. You more or less reduce the available surface area in contact with the terminal, because the cable cannot form to the shape of the terminal. In a ferrule, as Andy uses square shaped crimp, the surfaces all meet up pretty well, and they're that tony bit impressionable, so they will still form to the shape of the terminal. I have seen many videos covering the issue, just wasn't confident I had seen Andy do one. As for "another material", the ferrule is another material, so that's probably not a legit claim. It's all about the solder rigidly holding the shape of the copper strands in a round form, which reduces surface area of the contact between cable and terminal and this is the reason the connection has a higher resistance.

@@Victor-ut4zp Thank you. I don't see a problem either. You should be able to use any kind of BMS for your packs. If the settings are not the same, it should not matter either as the BMS with the lower settings will just shut off earlier. In saying that, the solar charge controller should be responsible for charging and there it uses the same settings for all banks anyway if they are in parallel. The BMS is more for safety if one cell gets too high or low..

I also bought a JK BMS and now I am working on a system using Victron MultiPlus II, Victron MPPT 100/20 and Venus. I'm using Li-Ion car batteries and due to the higher risk of them igniting one way or another, I keep thinking how I can make sure that a cell monitoring circuit (JK's circuit) does not give an error or short circuit and thus overload a cell that could lead to fire. So I was thinking of using another additional BMS with the only role of monitoring the cell voltages and cutting the battery if needed - the other one would be responsible for doing the charging/balancing alone. This way, I'd be introducing redundancy in case the charging/balancing BMS somehow fails. I'm curious if you've tried this and what your advice would be? I'm open to sending you a diagram of the system as I'm seeing it now.

It is possible to monitor most jkbms with serial and maybe bluetooth later. I will do this later. That in turn can control some alarm or mayby extra safety. And a suggestion is also to plan for the worst, if they go up in smoke how do you protect the rest, almost airtight capsulation, fire insulation and outside ventilation. Just in case also special fire supression siuted for litium.
@OffGridGarageAustralia
@OffGridGarageAustralia 2 жыл бұрын
If one BMS does just the charging/balancing and the other one the cell monitoring, there is no redundancy. You can only ensure that if both BMS do the exact same and if one fails, the other one is still there to protect.. I would not charge higher than 4V with Li-ion. I case something happens you still have a buffer.
