Budget 24V for Home office system

[HiwaOC]

Hey guys

Budget 24V for Home office system ( PC + 3 Monitors + Printer + light ) all together using around 285w one battery
setup:
POW-HVM3.2H-24V-N + Wifi Module
Langzeit LiFePO4 Batterie 100Ah 24V with BMS no Bluetooth to monitor i use an Atorch DT-20

all works nicely with watchpower app using an old PC with COM( using wifi module cable), but I would like to go one step further since I have a Raspberry Pi 5 in hand using Solar Assistant

since I can not buy the voltronic RS232 USB in Switzerland or Amazon Germany I purchased 2 different cables to connect to the included wifi module RJ45/RS232 - DB9 cable and no chance of having a connection

both with Prolific Chipset ---- No matching devices found error

yesterday I massaged a seller on Aliexpress and he confirmed below cable works with Powmr directly from inverter COM to USB

meantime to not sit and wait is it possible to have Voltronic RS232 pinout from solarassitant ? couldn't find it anywhere, to try modify one of the cables I have ?

thanks
