    Problem with Power Source prio PIP-MSE1

    Hello all, the alarm ofmy MPP SolarPIP-(2424-)MSE1 went off a few hours ago, informing me of a 04/Battery voltage too low error. The inverter was under load at that time. I was confused, because I assumed that it would switch to utility power, no matter if I set Output Source Priority (Setting...

    DIYBMS v4 thoughts

    Apart from the Question on how to order the preassembed modules on JLCPCB, which is now clear to me (thanks to @IronSky), I had the problem that the BOM and CPL files are not part of the git repository on GitHub. They seem to only be included in the zip file. So since I went the developers way...

    Sorry for the noob question, but how can I order these boards preassembled from JLCPCB? I know I can upload the gerber files for the boards, but how to go from there? Thanks!

    Remote monitor/control a PIP-2424MSE1 via wireless?

    Hello sun harvesters, Lately, I set up an MPP SolarPIP-2424 MSE1. I installed it off-grid in the garden shed, which is still within wireless range of the house. I would like to watch it via WatchPower or any other software from within my network.. but how areyou managing to do that? I know one...

    a couple of beginner questions

    I will also start using tinned or silver coated 0,2mm copper wire. I used plastic coated copper wire until now, but getting rid of the coating is always a big pain in the neck. I can only find silver coated copper wire, but I guess the ampere rating will be in the same ballpark. Which thickness...

    Whats the secret to opening laptop packs?

    Oh I praise the day when I saw Peter twisting the packs.. so much faster than having to pry every single one open. I just can't bring myself to smash them on the ground if they don't open right away.. Be careful with older packs with brittle plastic. Prying them open sometimes let shrapnels...

    Cell reviving question

    Thank you guys, putting a cell in parallel to ramp upa low voltage cell was more like a recent idea totest if an almost deadcell would take any charge at all. Usually, do as I learned from the youtubers andgently start low voltage cells by putting them together in parallel and connecting them...

    Cell reviving question

    Hi guys, I have a question about detectingbad 18650s afterreviving them fromvery low voltage (after being salvaged from alaptop pack). I used to kickstart an almost dead cell by connecting it to a working 4v cell for a couple of seconds. The voltage is usually being ramped up to 2.x volt, butI...

    Measuring cell temperatures while testing?

    Thank you very much guys! Cool that you have that kind of setup, Dan! I've must missed that video of yours :) I guess most important to me is to be able to trigger a 240 volt switch when temperatures get too high. Cool that you used Graphite and Grafana, though I guess my idea with keeping...

    Measuring cell temperatures while testing?

    Hi guys, did anyone ever came up with a DIY setup to measure the temperature while testing 18650 cells? Since I'd love to test all thesecells when I am not at home or during my sleep cycles, I am worried that I won't recognize when one cell runs too hot when bulk-charging them initially, right...

    Where Did You Find Us?

    Hi there, I started off with watching Jehus videos on youtube. I watched them all until my wife kept asking me if I am watching "the battery guy" again. At somepoint he referredto Peters channel, so I headed over and watchedmostof his videos, too. I only wanted to build my own ebike battery...
