Just witnessed MPPT voltage drop below 14V
Well this is interesting. Half sunny half cloudy day, 92 degrees out. Collected this data looking at the turnigy for the maximum panel output (not max amps to battery which was fun but not any real ob...

Take a very close look see at the Morningstar MODBUS interface protocol document, it contains what you are asking for. A wonderful document geared toward software programmers. Suggest you bite the bullet and purchase the programmable hardware to play with. Additionally move over to NAWAS forum where the extreme nose bleed solar folks hang out
I have done real time machine control with PCs before soft PLCs came out but it's been a long time. If anyone ever had a Ford Ranger, I coded the software that made that fuel line. Helped code some prototype OBD systems. Reverse engineered the original EECS IV ECU config tables and some of the code that ran the '96 SHO when it came out too (it was legal back then - no "do not reverse engineer" notices back in the day). That was fun because they had a custom chip from intel with instructions that no documentation was available for at the time (8052 variant maybe?).
I quit doing any serious coding around the time I learned SmallTalk when it first came out. But I can still run a code review with the best of them, in a pinch.
Never did modbus - dabbled more with the Rockwell stuff. What kind of development environment do you use?
I'm worried if I go over to the dark side I'll never come back. :) Maybe it's the light side since it is all solar guys? PV's have been around 50+ years (a lot longer as a curiosity) but it is still early days for the technology with lots of innovations coming quickly.
