Pls install the frimwere i put and go to logs and check serial ports log comm

For HV protocols , i upload new DIYB4I v1 with more easy debug function . For testing the protocol just use fake battery data. Also all ports can be tested for trafic / also the can msg comms

Can u put what is the inverter model that u confirm is working with pylon.

I think nodemcu have other pin then Esp32 DevKit 1 can u see if map pin is same?

Most of Easun inverter not support can bms, just rs485 comm. For 8 and 11 kw version exist an firmware update that support CAN will work with pylon protocol , i dont tested but u can try.

For u i simple just install Jk Bms Can Lv fremwere . conect one jk on rs485 one on serial the data will be combined . Select Pylon or Seplos. protocol. whatup on pm. The protocol is allready tested on solis lv. best regards

Because of lot of project i support in same time i need to make some management of projects, is hard to me to re take all conversation from forum for each of u, and some contact me in viber or whatup or telegram and in this moment is a big mess with lot of info. Sorry for that i try to give my...

CVL DVL CCL DCL and SOC are the data send to invertor by bms to work CVL - Charge voltage level DVL - discgarge voltage level CCL - charge curent level DCL - discharge curent level u can send only from on jk bms to invertor but will not have the real amp readings , also change the charge...

i am not Shure what u mean! If u have more battery packs in parallel all packs will have same voltage on enads so in theory is same SOC, but if u have a cell on 3.5 and rest are on 4 V the pack is not 90 % because the cell from 3.5V will discharge to protection faster! so in the end when use...

jkbms will work sp200 controiller no
