    [Solved] MPP Solar/Voltronic display "bricked"

    Found out what the problem was. I used WatchPower (the serial setting/logging utility) before to test the connection and then I closed it. But it wasn't actually closed and it was running hidden in the system tray area. I assume it tried periodically to connect over the same serial-usb...

    JK BMS CAN bus comms now possible for inverters that support Goodwe and Pylontech batteries

    Thank you @Sleeper85 for the continued support. Did anyone try an ESP8266? I have a bunch of those lying around that I need to use up. Or I can use the one already connected to the inverter doing the "pipsolar" home assistant integration. On another note, my inverter is MPP Solar 6048MT...

    [Solved] MPP Solar/Voltronic display "bricked"

    It's really cold in the attic right now :) Probably around 10C or less.

    [Solved] MPP Solar/Voltronic display "bricked"

    I only have one firmware file VPSK.hex, not sure if that is the DSP or the display board.

    [Solved] MPP Solar/Voltronic display "bricked"

    I have a PIP6048 (removable display) and was going back and forth with the support to get them to fix some severe issues. They sent me an upgrade folder and I promptly proceeded to follow the instructions. The inverter then went offline and came back with warning 32 (no communication with the...

    Please double-check my BMS and inverter settings

    Hi @spuki thanks for the suggestion, I was planning something like that. I did not calculate what load I could use, have several power resistors around as well as several 200W tungsten lights. There hasn't been any sun here until today, but I found several grave issues with my MPP Solar...

    Please double-check my BMS and inverter settings

    Does not do anything, it needs repeated presses. The range is from 42V to 60V, I think, with 0.1 increments, so 180 presses to go around. 179 presses if you want to go down .1V Thank you, I might take you up on that offer. As far as I have seen, no, but I haven't discharged the cells all the...

    Please double-check my BMS and inverter settings

    The voltages equalize once the battery is slightly discharged and they stay equal all the way to 49V or so, didn't go below that. I double-checked everything with a meter when I built the bank. Thank you, good catch with the balance voltage. That's difficult to do. It literally takes 100...

    Please double-check my BMS and inverter settings

    Not all cells reach 3.37V. Now it's set to 54.1V. Will attach below You probably mean 2.8V? But I've figured it out, the battery is an "overachiever" and I progressively increased the capacity entry in the BMS to 135Ah. This now yields more accurate results. I thought the BMS will...

    Ideas / products for all-in-one system?

    Just to finish this off in some way, the system is built and already deployed. I did end up putting a lot more protections, but not excessive: wire fuses from panels, into the discharger units then into the inverter, all in a DC breaker box. The AC breaker box has just two breakers to switch the...

    Please double-check my BMS and inverter settings

    My findings so far: The inverter will quickly go from bulk to float charge, limiting charging current severely. I've increased the float voltage to 55.4V on the inverter and let the BMS do its job. I cannot top balance. Even if I reduce the current a lot, some cells will reach 3.6V while most...

    Please double-check my BMS and inverter settings

    I'm using an MPP Solar 6048MT with a DIY 48V 125Ah battery. The battery is fitted with a 150A JK-BMS. My goal is to use the sun whenever possible, charge the battery if some extra remains, use the battery until a safe low voltage then switch to grid. In the winter months it will most likely be...

    Terminating balance wires

    Finally found something, sorry for the late reply, it seems that thread subscription is not automatically activated for the owner. I made a slight mistake and thought the terminals are M8 but instead they were M6. I bought some M8 terminals that were insulated - would not recommend them, or at...

    Terminating balance wires

    I have a JK-BMS B1A20S15P with very thin balance wires. No idea what gage, but probably AWG18-22, I'm not used to imperial units. I need to connect them to 8mm battery terminals but I could not find such lugs in the hardware shops around the area and online. I'm in the EU. Do I need something...

    Ideas / products for all-in-one system?

    Going through the manual for the PIP-6048MT it advertises >98% efficiency when running in line mode and 55W idle consumption when in inverter mode. I assume that idle consumption does not happen when running in line mode, but without someone confirming this or asking the seller, I have no way of...
