I was firmware 46.0x in my Easun SMW 8 kW which I bought in february 2022. I flashed in autumn from initial firmware to firmware from this thread based on 90.06 (150V version). Now i use shadow management beta firmware from Georg594.

I using ESP32 with program in ESPhome for monitoring JBD BMS in Home Assistant and for a week ago I made connection to MAX 8k over CAN bus with protocol Soltaro (thank Coulomb and other users for information about this protocol). Function of connection is good, atfer some seconds flashing battery icon on inverter LCD and in information menu is new information about numbers of battery pack. One problem is with setting voltages because max charging voltage is setting for absorption voltage and for float voltage (boath is the same) in inverter. I was must made a small controling in ESP32 which change voltage from 55V after charge battery to 53,6V (and back tu 55V when battery is discharged) but this was not problem and all function verry well.Hi Coulomb, now i view graphs from this morning and both MPPTs function the same and both MPPTs go with voltage to 120V when current is under 1,5A every cca. 10 minutes.

AXPERT MAX 8 KW SHADOW MANAGEMENT Firmware upgrade BETA & (still based on stable 90.06)
Hi Georg, I install this FW two weeks ago (previously I was use your beta FW with MPPT patch to 175V). This FW function quite good in cloudy weather and in sunny with shadow from tree on one string (afternoon) is power better then previous FW. Bye Petr

Hi everone, yesterday I was upgrade FW in my Easun SMW 8k with patched FW 90.09 175V version and all is ok. With original FW was on PV input voltage 90V with current to 0,5A from panels and over 0,5A voltage going up. Now going voltage up from current 0,1A. Yesterday was the same weather as today (inversion). Yesterday was power from PV 30-40W with current 0,2-0,3A and today was power over 100W (yesterday was 100W peak 2x for all day) with current 0,2-0,3A. Original FW was 46.05 and display 112.11. First I upgrade display to 112.19 (from download section in this forum) and then I upgrade 8kW.zip 175V version (thank you Georg).
