+===== Connecting to the Electrometer =====
+----
+==== Installation ====
+Solar Monitor can be connected to Green Bonus electro meter with binary input DI3. It reads the energy output of your PV plant.\\
+\\
+//The following picture shows how to connect to the electro meter with S0 (puls) output:// \\
+\\
+{{  :en:sim:manual:jak_na_instalaci:elektromer.png?nolink&  }}\\
+\\
+In order to get the right data, the right number of pulses per 1 kWh must be set up in the unit.\\
+<WRAP info> Default setting is 1000 pulses per 1 kWh. If your electro meter has different number of pulses, change the default setting value. </WRAP>
+==== 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 [[:en:sim:manual:menu_nastaveni:stridace_a_mereni|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 result into relevant box in SM2-MU menu  [[:en:sim:manual:menu_nastaveni:stridace_a_mereni|Inverters and measuring]].
+\\
+<WRAP info> 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: </WRAP>\\
