Hello.
I was looking for and found.

Ground Problem Modbus Communication

Hello, After reading through some other ground problem topics, I could not really figure out a solution for my situation. I built a power source based on PV, battery and charge controller based on 12V. This power source shall supply my outdoor micro-controller projects with power. The power supply in general works well. My charge controller though has a COM port from which I can get hold of details regarding the loading, charging, etc. and I would like to capture and use this data. The capturi…

Reading Solar Charger COM via MODBUS (MAX485) Problem

Dear all, I am trying to read the COM output from my EPEver Tracer 1210AN using a Mega+WiFi board via a Max485 module. My primary orientation and references are the following... Similar project based on NodeMCU, Max485 and Blync: Cheap MPPT Controller Live Stats on Mobile - Hackster.io Pretty much the project of me except for the arduino board being different and a different charger model is being used, I copied the code from the screen, the code has strong similarities with previous or…

It works.
How to read all the data?
There only PV Voltage, PV Current, Battery Voltage, Battery Charge Current.
How to get other information?
Thank you.

How to get other information?

read the registers of "the other information".
Check the datasheet which register is needed for which information.
