Anyone recognize this protocol?
« on: December 10, 2019, 09:05:01 AM »
Gents--Attached is the COMS protocol for my LiFePO4 batteries.  Does this look like MODBUS, CANBUS, some variant thereof, or a totally custom system?  I need to us a Pi or Arduino to read SOC & voltage, and toggle various elements of my system.  Posting this in the Arduino forum as well.  Thank you.
BTW--Can anyone recommend a specific RS485-to-USB adapter that WORKS!?
Two 1.5 kW arrays --> two Classic 150s --> WbJr. --> four parallel 100 Ah/48 volt rack mount LiFePO4 --> Outback FXR3048 inverter.

It doesn't look like either one of those two protocols to me.

@OpenPlanet  I use a USRIOT device with RS485 & RS323 (D sub) ModBus to Ethernet converter.

There are several models to choose from.  but there is another serial to wifi & Ethernet converter.

Hope that is of help.
