Detailed Description
 


Energy Monitor is a great tool for monitoring Power and Energy generated from the energy sources to the connected load.

Energy Monitor is a great tool to monitor the status of the renewable energy source to the load. The voltage, current, power and energy are monitored. The resistance of the Load is also displayed. It is a great tool for comparing the performances of a wind turbine or a renewable energy system under different operating conditions.

 

While most Power Meters are designed for AC power line application, the EM-1 is designed to meet the needs of evaluating renewable energy system applications.

 

The energy displayed is the Energy delivered to the load immediately after the Energy Monitor is powered ON. The powered ON time duration is also displayed. The Power displayed is the instantaneous power delivered to the Load.

 

A unique feature to display the instantaneous rotating speed of the wind turbine in RPM (rotation per minute) is implemented. This feature is specially designed for our WindLab, WindCharge and WindPitch 3-Phase wind turbines .

 

This meter can be used for the Maximum Power Point Tracking (MPPT). By adjusting the value of the Load resistance when the Power is displayed, we can observe a peak power at an optimum resistance value. The maximum power from the source can then be extracted. The resistance of the connected Load is can be displayed.

 

You can press the “Function” button to select the Data to be displayed in the following order: Voltage -> Current -> Power -> Energy -> Rotation Speed -> Time (MM:SS) -> Time (HH:MM) -> Resistance -> Voltage again. The LEDs on the right side show the function and unit that the 4 digits are displaying.

 

You may also select the “Scan” Mode to display Voltage -> Current -> Power -> Energy -> Rotation Speed -> Voltage again so that you can read them sequentially every 0.5 second.

 

The “Auto-OFF” mode turns OFF the LED display after 5 minutes to reduce the power consumption while the Energy Monitor continues to record the energy delivered to the Load. The “Scan” LED blinks to indicate this “Auto-OFF” mode. You may also use a DC Adaptor to supply power to the Energy Monitor.

 

The “Resistance” LED blinks to indicate the Battery level is low. You should replace the old batteries with new ones.

 

The Resistance displayed by EM-1 is calculated by dividing the Voltage by the Current flowing to the Resistor. Sufficient Voltage has to be applied to the Input terminals to get enough current for calculation..

 

When the polarity of the power is reversed, the “Reverse Polarity” LED is lit. You should reverse the polarity of the input connection.

 

The Energy Monitor samples the voltage and current data 2000 times per second. The data are averaged and the power and energy are calculated.

 

This Energy Monitor is also great for evaluating wind turbines and Solar Panels.
