Step 4 - Counter Settings

In case there is no electro meter connected to your Solar Monitor, go to Next >>

In SM2-MU web interface go to menu Settings/Inputs & Counters

For input with a connected meter select option Counter in table Inputs and Counters. Meter can be connected to all 3 inputs. You can connect up to 3 meters to SM2-MU.

In upper part of the table there is name of the counter. Enter its name (e.g. electro meter) and select its type. Set up correct number of pulses per 1 kWh (as stated in SO output parameters at the counter).

Enter counter status (e.g. total production at production electro meter).

Default setting reads 1000 pulses per 1 kWh. If your electro meter shows a different number, change the setting. If it is 1000 pulses, go to Next >>.

The number of impulses per 1 kWh is usually between 250-1000 imp/1kWh. In case there are 2 possible numbers of impulses at your electro meter, the lower number is usually the right one for the SO output.
The higher number tells you how often a LED diode at your electro meter switches on.

Follow instruction bellow in order to setup a number of pulses different than 1000 per 1 kWh:

1. Direct measuring

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.

2. Indirect measuring

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 whole formula (i.e. 10000/30) into relevant box in SM2-MU menu Inputs & Counters.
