Hi Frits, sorry for only replying now but I only received the tapatalk notification.

I also ordered a pi after first hearing about it on the old aicc website. I installed it, got it working, but it just didn't do it for me.

Manie was so kind to go ahead and develop a new ICC for windows in record time and i must tell you, it's been running for more than a week now without any issues. On a windows machine you download, extract and run, that's it. No hassles whatsoever.

Mockups of what will be on the main screen.
Screen 1
Battery SOC (State Of Charge, %), Volts, Amps, Units in(Kwh), Units out(Kwh), Run time, estimated remaining time, Load (Kw)
Solar panels Volts, Amps, Units in(Kwh), Load (Kw)
Grid Volts, Units in(Kwh)
House Load (Kw), Units used(Kwh)
Screen 2
Total volts, State Of Charge, Temperature
Inidividual battery voltages
Individual battery State Of Charge
Individual battery temperatures
 

Some progress. 
Writing firmware is a long slow process, especially if you can only spend evenings on it. Here's the control unit in it's box, with the LCD operational. I've completed various firmware modules by now (Real Time Clock, console interface, USB serial port, WiFi interface, LCD interface, etc). These are all the "building blocks" on top of which the main application will run. Should be starting the main application soon...

Well done, Weasel, you've spotted most of it.
This is a monitor and control system for my Solar installation, it will feature:
Monitoring each battery's voltage individually (string of 4). Monitor each battery's temperature (up to 16). Measure current into and out of the batteries. Measure current and voltage from PV's. Read grid voltage/Wh from the inverter. Integrate all this to determine Wh obtained form the sun, into batteries, used by the house, etc. Control the (Axpert) inverter to make optimum use of the batteries (not just based on voltage, but on SOC). Try and optimise usage of the PV panels. Display any 10 parameters (on the 7-seg LEDs) in real time - for viewing at a glance / from a distance. UI on the LCD for configuration, graphs (maybe), etc. Log to an SD card. Report via WiFi for remote access. Alarm indication with buzzer. Relay outputs to allow, for example, an aircon or geyser to use excess PV energy instead of wasting it once the batteries are full. Estimate remaining battery run time and display in real time. Integrate with the battery balancer (coming soon) Count battery cycles, monitor battery health over time to guess life expectancy. Etc. All this without having to keep your computer on.
