How to Setup Reading Pulses from the Electrometer


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


V tabulce Vstupy a čítače vyberte u toho vstupu, do kterého máte připojené měřidlo, funkci Čítač. Pozn.: Měřidlo může být připojeno do každého ze tří vstupů. Do SM2-MU tak můžete připojit až 3 měřidla.



V horní části se objeví tabulka čítače. Zadejte jeho název (např. elektroměr) a vyberte typ čítače. Nastavte správný počet pulzů na 1 kWh (dle parametru výstupu S0 na čítači).




Zadejte stav na čítači (např. celkovou výrobu na elektroměru výroby).



Default setting is reading 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 Inverters and measuring.

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 Inverters and measuring.





When you have changed the setup, remember to save the changes .
