MODDB for State of Charge

I am using a Raspberry PI to pull data off of my Midnite Classic. I am using the excellent Newmodbus. Is there a address to get the state of charge from the WhizBang JR?

Thanks,
David

Which version of newmodbus (or from where?).
I think the last version I've released is 1.0.19

I believe 4373 is SoC and 4321 is the WBJR Current.
3600W on 6 tracking arrays.
7200W on 2 fixed array.
Midnite Classic 150
Outback Flexmax FM80
16 x LiFePO4 600AH cells
16 x LiFePO4 300AH cells
Selectronics SP-PRO 481 5kW inverter
Fronius 6kW AC coupled inverter
Home-brew 4-cyl propane powered 14kVa genset
2kW wind turbine

Ross;

Speaking of Newodbus, any clues on modifying it to pull data from an SMA SunnyBoy Grid Tie inverter with it? Or any other method?  Most of their online docs are about their add on module but this inverter supposedly has it built in. SMA has not responded to my inquiries via email and phone support dropped my calls 3X times. Sadly, not all manufacturers are as responsive as The Midnite Solar team.

Thanks.

Thanks for you help. That is indeed the correct address for SOC.

How do you make the connnection from the Pi to the Classic ?
thanks

I'm not David but;

Unless they changed it, newmodbus used ethernet.

You can read the raw data from the serial (USB) port once you tell The Classic to push the data out through it, as well.

Ethernet is much more elegant, however. And you don't need a USB cable to your device reading the registers, just the existing ethernet connection most have already.

Its been awhile but my feeble memory tells me that is how it worked.  ;)

I guess that makes sense  = modbus over IP  - that is how the Local Status app does it I suppose - and Grahams Classic Monitoring app. I know some people connect stuff up over the the serial port too - maybe just when they use Arduino's .
