Solar Monitor can be connected to Green Bonus electro meter via any of three binary inputs DI. It reads the energy output of your PV plant.
The following picture shows how to connect to the electro meter with S0 (puls) output:
In order to get the right data, the right number of pulses per 1 kWh must be set up in the unit.
Default setting is 1000 pulses per 1 kWh. If your electro meter has different number of pulses, change the default setting value.
In the electro meter's label or documentation find out how many pulses per 1 kWh your electro meter generates at the SO output. Fill in this value into relevant box in SM2-MU menu Inputs & Counters.
In the electro meter's label or documentation find out how many pulses per 1 kWh your electro meter generates at the SO output. Use this number in calculation, see example bellow.
Example: Electro meter's label states 10 000 impulses per 1 kWh.
Look at the indirect power measuring transformer (1 transformer connected to each phase) and find a ratio (e.g. 150A/5A). Use the result of this ratio (30 in this example) in the formula (10 000/30). Fill in the result into relevant box in SM2-MU menu Inputs & Counters.
In case you want the electro meter connected to the Solar Monitor and use pulse output for another device (e.g. Wattrouter) at the same time, follow instruction in the next picture:
