Freaks,

I am trying to build solar cell + inverter + SMPS voltage monitor.

The inputs are:

1. Solar PV cell voltage and current.
2. Input voltage from PT (potential transformer)
3. Current through CT (current transformer)
4. SMPS Voltage and Current.
5. Inverter status (on/Battery low/overload)

The outputs are:

1. SMPS switch (ON/OFF)
2. Inverter switch (ON/OFF and RESET)
3. RS232 interface
4. Ethernet
5. GPS
6. GSM/RF (for remote logging capability)
7. LCD
8. USB

The main point of this project is data logging ie. to b able to send an update of the front-end (PV/inverter/SMPS) once every morning, every day remotely. Also should be able to control the system (nos.1 and 2) remotely i.e. through internet.

Based on this, which uC should I use? I understand this is an AVR forum but if anybody has a suggestion on which ARM microcontroller to use, I would appreciate it as well.

Thanks a lot for your help.

I'd use a commercial off the shelf part for each of those components in the parts list. Don't need a custom designed part unless you cant find something to buy that will work. Like an ATX single board pc. They have serial and ethernet etc etc.

http://archlinuxarm.org is a good place to poke around. Beaglebone, Pogoplug, Raspberry Pi, etc. can run a substantial Linux with LAMP ethernet webserver and available drivers for USB dongles like GPS and Wifi.

Thanks,Guys. The archlinuxarm site looks interesting. Will do some R&D on this.

Ok I went and checked out Raspberry Pi and it seems I will have to buy the manual. Anybody have an idea how I can connect the above inputs to the board? What ADC's are on-board?
