hmmm didn't read the whole thread but I have two JK in parallel, each battery has a high quality (ABB) non polarised breaker (80A) before the bus bar. probably going to add some class-T down the line just in-case.

what do you think? genuine? I have seen a 315AH cycle from the pack, 3.0 to 3.43 but didn't get the chance to absorb so probably a little more in it. happy enough :)

no rush. i see the board pins etc are defined in the packages/board files. when compiling/flashing with esphome on home assistant will it pull down the packages automatically or i'll upload them to HA? sorry for the questions ahah i'll go have a google now :D

mmm ok. I should see what happens tomorrow, should get a full charge in it.... (its possible the new battery gets full before the old one, which is the one talking to the inverter). with the multi BMS, I assume I could use either multi-bms_wire_pvbrain2.yaml or multi-bms_wire_one-esp.yaml ? I...

quick question regards the EOC state, now that the ABS time is gone in the latest version, how is it calculated? # End of charge (EOC) will be triggered if current and max cell voltage meet cut-off thresholds, plus the cycle count exceeds the below threshold I assume max cell voltage is the bulk...

About to flash the newest version, I notice goodwe protocol has been removed (I think?) should be fine if I use pylon+ and reconfigure inverter to pylon batteries yeah ? *ahh nevermind, i see the protocol is set from a drop down box now rather than in the code :) I also added a second battery...

Here ya go :) QR scanner wouldn't pick it but iirc gobel power site worked

Latest purchase 16x catl 'new version' 302 (apparently 310-318) from docan for ~ 65 USD/+s&h. The QR indicates manufacture date of March 24. I didn't actually test any of these, just put them in a box and started using them (in P with another 16s pack of 1.5 yr old catl302) but so far so good...

yep, I see exactly the same thing. As far as I can tell, the 100% reset happens when any cell hits RCV, but the absorption timer only kicks in when the pack voltage its maintained at or above RCV x cell count. At least it seems this way, because I have not seen abnormally short termination of...

ah yeah makes sense, as the draw falls close to zero the voltage rises up. I was just back to front hehe :)

Mppt regulates the input by raising the voltage, if you look at the curves of any panel, past the maximum point the power drops off a cliff. By this method the controller isn't burning off power, it just isn't produced. Even the largest array can easily be reduced to essentially zero. Hence why...

I have a victron 150/45 (max power 2600w @ 48V) with an array around 3kw (VOC ~110V, Isc ~40A), fwiw it clips at around 2550w into the battery when the PV would have kept going up, seems happy enough. Also planning to put around 6.5kw on a 250/100 (max 5.6 ish kw). Also notice my goodwe in a...

yeah, similar to what I see. With the victron once float kicks in after the ABS time, it generally sits around 99-98% for me, and the system draws a little from the battery until the voltage drops to the RCF value. The soc jumping is annoying but so far hasn't been a problem. I could see a case...

Yes, type b victron cable works with these (tested with a victron anyway! Not sure about other inverters) Curious if you guys get the issue I have with this bms where the soc could jump from 85-90 ish straight to 100 under some conditions, if charge suddenly goes from low to high (4-5kw) and a...
