    My Settings for MPP Solar PIP-2024LV-MK 24V System

    I don't know about the 2424LV-MSD but the 2024LV-MK idles at ~1.16A from 24V battery setup (the picture below shows 1.26A but 0.1A is from the RPi4 I have connected) when inverter is on. As for the fans, in the setup pictured below (inverter on but not loaded), the fans are on but at a very low...

    My Settings for MPP Solar PIP-2024LV-MK 24V System

    Melted plugs? Which plugs? 60A on a 24V system would equate to roughly 15A at the 120VAC input to the MPP Solar box which is right at the limit of what a typical 12AWG extension cord is rated to handle (20A at 60C). On the battery side, I'm using 4AWG wire as recommended by the MPP Solar manual...

    My Settings for MPP Solar PIP-2024LV-MK 24V System

    Oh also, Solar-Assistant.io is AMAZING!!! Highly recommend it to anyone with an MPP Solar box. Just being able to view and change all the settings on one page on your phone or browser makes everything much easier. Also, all the data and graphs are pretty cool! I'm thinking I may buy a Victron...

    My Settings for MPP Solar PIP-2024LV-MK 24V System

    I finally got my setup up and running and everything's going smooth so far. The fuel gauge is not accurate but I'm not even looking at it because I know it's wrong and I am now using solar-assistant.io Emulated BMS feature to tell me the correct state of charge. @iamrich turns out Program 11...

    My Settings for MPP Solar PIP-2024LV-MK 24V System

    I would recommend investing in a power supply and not a charger. A power supply is more versatile (can be used for any project) and can accomplish the same thing as a charger. Also, look into https://solar-assistant.io/. It seems like a relatively new program/monitoring system that uses a...

    My First Portable Solar Generator Build

    Alright well since I've gotten no response, I'll just use this thread to document my build. Maybe it will be useful for someone in the future. First things first. I finished top balancing the two batteries and then I disconnected them from each other so I could do a capacity test on each one...

    My Settings for MPP Solar PIP-2024LV-MK 24V System

    I'm confused. The voltage was lower after you charged your battery with your charger (from 13.5V to 13.38V)? Honestly, this is why unless you have a LiFePo4 specific charger, I would say it's best to use a power supply instead of a charger that was not made for LFP. As for the MPP Solar unit...

    My Settings for MPP Solar PIP-2024LV-MK 24V System

    You can’t really use a voltage reading as an accurate indicator of SOC since in the middle the voltage curve is so flat that they could read very close in voltage and be very far apart in SOC. What I did was first check voltage to ensure they were close to each other (in my case they were...

    My First Portable Solar Generator Build

    I've finally got everything and now I just need to put it all together. Before I do, I would greatly appreciate it if you guys could take a look at what I plan on doing and let me know if you see anything wrong with it. List of equipment: MPP Solar PIP-2024LV-MK 2kW 24V All-in-One Two SOK 12V...

    Top Balancing Acting Weird

    All of this makes sense and it's what I've understood based on my readings. Still not sure why 14.4V caused this "issue" but 14.6V did not. Unless of course by the time I tried 14.6V the cells had had enough time to balance enough at 14.4V that when I went to 14.6V, the BMS did not have to do...

    Top Balancing Acting Weird

    Had to read your post a few times to internalize what you were saying but now I get it. Thank you for the thorough response. At this point the only thing that confuses me is the fact that when I set charge voltage to 14.6V it eventually drew 0A and stayed there without this issue occurring...

    Top Balancing Acting Weird

    Not sure how I'd be able to tell if one battery is tripping before the other one. This doesn't make sense to me though. If I hit 14V and it stays there for a few minutes with 0A of current draw, why would the BMS trip? I understand if it tripped while current was being drawn from the power...

    Top Balancing Acting Weird

    I have two SOK 12V 100Ah batteries that I'm top balancing by wiring them in parallel and applying 14.4V with a current limit of 4A on the supply. Everything's been fine for a couple of days and today it finally hit 14.4V. This whole time the supply display has shown CC at 4A limit until it got...

    My Settings for MPP Solar PIP-2024LV-MK 24V System

    Thank you so much for taking the time to provide your input. You are 100% right about Program 11 - Max Utility Charging Current. That's a great catch and I'll definitely be dropping that to 10A! The following are the updated values I plan on using based on your feedback: Program 11 - Max...

    My Settings for MPP Solar PIP-2024LV-MK 24V System

    I've been reading Will's recommendations, watching other Youtuber recommendations, reading this forum, and corresponding with SOK (company that makes the two 12V 100Ah LiFePo4 batteries I'm using) to try to figure out the best settings for my MPP Solar PIP-2024LV-MK 2kW 24V box. Since there are...

    Breaker or Fuse for 24V System

    I'm building a 24V LiFePo4 (two 12V 100Ah SOK batteries in series) off-grid system with an MPP Solar 2024LV-MK. I've bought the Victron MegaFuse 32V 100A fuse to go between the battery and the MPP Solar box and am using 4AWG wire. So my questions are as follows: I've read somewhere the...
