    Horsefly's 2nd Cabin battery build

    Thanks. I got concerned by this thread: https://diysolarforum.com/threads/aluminum-heat-spreader-in-direct-cell-contact.80384/ but I do think my fears are overblown and there should not be any problem putting the cells directly on top of the aluminum plate, as they do have a thin layer of...

    Horsefly's 2nd Cabin battery build

    @Horsefly this battery build has served as the inspiration for my own insulated battery box, it's really great. One question - did you add anything between the aluminum heating plate and the cells?

    What's the trick to fitting 0 gauge wire on this breaker

    You could try @42OhmsPA ’s trick: https://diysolarforum.com/threads/how-to-connect-the-black-style-jk-bms-with-the-short-b-and-p-leads.82942/post-1076500

    Grounding and Starlink

    Was there any surge protection in front of it? Directly to the south of the tree is a lake -- the land slopes up to the north (the direction that the dish is pointing). There are plenty of trees surrounding it that are taller, but not tall and close enough where I believe they're obstruct the...

    I appreciate your pragmatism, @timselectric.

    Starlink 12 volt POE, or not

    FYI I am doing this @AlaskanNoob. I'm using this POE injector: https://www.amazon.com/dp/B0CQC4321X. I have it hooked up directly to my 48V bus bar through a 4A DC breaker. My battery is set to absorb to 55.2V, which is below the POE maximum of 57V. It's been running for a couple weeks like this...

    Grounding and Starlink

    Thanks for all the feedback folks, this is helpful. Isn’t it though? Starlink is powered by POE coming from my battery, which is bonded to my house ground through the shielded ethernet cable. If the dish is also bonded to the pole, wouldn’t adding a ground rod at the tree create a ground loop...

    Grounding and Starlink

    I've recently installed Starlink at my off-grid cottage, however the number of trees cause a large number of obstructions for the dish. I've seen some videos on Youtube of people mounting their dishes in trees and I think this is my best option. I've reached out to a local arborist who will take...

    Off grid system upgrade

    Another update! A week or so ago, I decided to temporarily assemble my battery at the cottage while I wait for my battery box to be built. This allowed me to complete pretty much all of the DC wiring and get the system up and running. I will probably create another post for my DIY battery once...

    How to connect the "black" style JK-BMS with the short B- and P- leads?

    I don't think it matters -- unless your negative is grounded: https://electronics.stackexchange.com/questions/445740/does-it-matter-if-a-fuse-is-connected-to-the-negative-or-positive-terminal-of-a

    How to connect the "black" style JK-BMS with the short B- and P- leads?

    I had cropped the class T fuse out of my original picture. Here's a larger view of my inner battery box that includes it: My fuse is connected directly to the positive cell terminal. This inner wooden box is going inside of an insulated custom fabricated metal enclosure (which is shipping out...

    How to connect the "black" style JK-BMS with the short B- and P- leads?

    @Skypower it was that picture of your BMS that inspired me to mount my BMS the way that I did! 🙏

    Grounding a stand alone sub panel

    I'm in a similar situation as OP and could also benefit from clarification (I'm shining the timselectric bat signal). I have an off grid system with a Victron Multiplus II 48/3000 inverter with the AC out back feeding 120v into a sub panel (6 spaces, 12 circuits). I have a small 2600W floating...

    How to connect the "black" style JK-BMS with the short B- and P- leads?

    I’m using ones similar to what you linked, with heat shrink. I bought a pack with various sizes, but I think those Wirefy ones should be good.

    How to connect the "black" style JK-BMS with the short B- and P- leads?

    Designing and building my solar system has pretty much been my primary focus for the past 6 months. I don't feel like I'm ripping through anything lol. I've spent soooo much time going through these forums and learning from everyone here. All the stuff you're mentioning are things that I've also...
