I have this kWh meter that records my production:

Can I simply connect the SO+ to the 5V and the SO- to a resistor and a digital pin of the arduino and then simply read it with a digital read? As shown here:

Is it that simple?
What value does the resistor have to be?

no,

check - http://playground.arduino.cc/Main/EEM12L-32AKWhMonitoring - how I did it with a very similar KWH meter.
