    Series Panels / Same Output

    Yeah, you got it - the max input is 150V I only have two panels, so trying to find the most effective way to connect them for the battery is definitely the goal here. My battery system is 12V, and I've double-checked the BMS isn't interfering. Curious to know why I would need at least 2s if it...

    Series Panels / Same Output

    Thanks for the detailed reply! It's definitely the MPPT model, that's been confirmed with the company itself. I'm wondering if it's something to do with the SCC settings, and if there's some throttling happening for some reason, if it's already kicking in to Absorption mode before the LFP...

    Series Panels / Same Output

    Thanks for your reply! No loads on the system - was just looking to charge my battery only. Battery SOC was approx 80%. I'm going to have to double-check the settings of the SCC to see if there was any throttling being done by SCC logic to see if it was already in Absorption mode, instead of...

    Breaker or Anderson plug between panel and charger

    Quick question, for a small setup with 2x 255W panels, do I actually need a DC 2P breaker? If I wire them in series, at max solar production it could potentially be 74V at 9A. If in parallel, 37V @ 18A So in this case, would a normal 50A Anderson plug be a reasonable way to connect the panels...

    Series Panels / Same Output

    Hi all! I've got two Canadian Solar 255W panels. Tested them for open circuit and looks good. Today was a pretty sunny day in Alberta. Set up both facing the sun at an optimal angle, and both were individually showing only about a 125W charge being delivered to the battery at ~9A which...only...

    Breakers and fuses for small system?

    Two quick questions: 1) I'm trying to figure out what type of fuse or disconnect I need on the PV panel side of this setup, or if I even need one at all? 2) Is the ANL fuse between the MPPT and the battery even necessary, since I have the MBRF fuse on the battery itself? Thanks in advance!

    MRBF Fuse brands (Canada edition)

    Oh, the South Bend Components webpage is complete dogshit, but the "Portfolio" page references the GRiP brand. https://www.southbendcomponents.com/ "Canada edition" was just because while Blue Sea seems to be universally available, I've only seen South Bend Components referenced as something...

    MRBF Fuse brands (Canada edition)

    Looking for the collective wisdom of the forum here. I ordered both the Blue Sea MRBF fuse and block, as well as the South Bend MRBF fuse and block, since everyone seems to know Blue Sea's reputation, but I couldn't find an opinion on South Bend. From what I could find online, I believe South...

    Finishing DIY Packs - Dead Shorts and Fuses

    Well holy cow, that's a first. Just to triple-check one point, after I've assembled my 12V cell, I should tape off the exposed metal on the bus bars and terminals for each cell? So, because I can turn off the charge/discharge paths via Bluetooth on my BMS, I could actually just use this...

    Finishing DIY Packs - Dead Shorts and Fuses

    Hello, About to begin assembling a 12V pack right now with 4x EVE LF280K battery cells. This weekend's rabbit hole topic was fuses and master disconnects. After distilling a few dozen (hundred?) of previous comments, noting the excellent input of @John Frum in particular, I just wanted to...

    BMS App with use tracking...or a good cheap shunt?

    Looking for recommendations here. I'm using the Overkill BMS app with my JBD 120A BMS (JBD-SP04S034-L4S-120A), and after tweaking the settings it's been working fantastic. However, I can see more clearly now that tracking how much battery I've used while I'm off camping is going to be a bit...

    MPP Solar 1012 vs DIY Milk Crate

    I actually think I figured out the answer to this one, at least the theory since I don't have the parts to test the practical yet. Two main reasons (that I stand to be corrected on by someone with more practical experience): 1) An MPPT charge controller isn't the best equipped for "processing"...

    MPP Solar 1012 vs DIY Milk Crate

    I'm looking to build a version of the Milk Crate all-in-one, but I'm having a hard time finding an MPP Solar 1012LV that would ship to Canada for a reasonable price. For the battery, I'm planning a DIY LiFePO4 based one EVE 280K cells and a Daly 120A BMS with Bluetooth. As far as I can tell...

    Battery / Charge Monitoring Bluetooth

    So, I guess I did my research on this one @sunshine_eggo? #1 provides a complete overlap of the information that #2 and #3 might have available, but also gives me the cell-level monitoring?

    Battery / Charge Monitoring Bluetooth

    Probably a bit of a newbie question here, but I'm at the stage where I'm starting to buy equipment, and with the various options out there I'm wondering which of these three options is better for the most in depth and useful monitoring of my batteries. 1) Bluetooth-enabled BMS; 2) Bluetooth...

    Is this something you're planning to sell? Or something that you're just doing as a hobbyist building nice cases for your own use?

    NOAH'S ARK: Index of LiFePO4 cell manufacturers

    @Dzl Do you have an recommendations for Canadian options? It would be fantastic to have a resource like you've created for the US-onshore options for your Northern neighbours (who are still struggling with Alibaba, etc.). Thanks!
