Hi Guys,
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 be 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 Keil board should I use? Any suggestions are welcome.
I had shortlisted the MCB1700 board but it does not have a GSM/RF chip in it.
Will it be possible to externally connect a GSM modem to it?
Thanks a lot for your help.
