Thank you for sharing this! I'm going to have to do some investigation on my own solar charge system.

I really only need one thing from the charge controller for my battery monitor. The charging state (bulk, absorption, float, etc...) is needed to keep track of battery cycles details. It's much easier to just have the mode instead of having a state machine function on the monitor computer trying to deduce the current charging mode from voltages and currents. My plan is to have a dedicated 8-bit microcontroller (PIC18F1320) on the modbus (using the 5vdc on the RJ485 plug) that decodes the register data and sends an analog voltage (using PWM for a DAC on a digital channel) to one of the battery monitors ADC channels as a series of voltage steps [0,1,3,4,5] for each mode.
