It shows and compares the energy produced.There are two graphs. The graph on the top is a bar chart of produced energy. The lower graph can present: Production and Irradiation, Phase and Total Output, Current, Voltage, Frequency and Temperature. Right bellow the menu there is a box where you can stipulate the time period for both graphs.

Graph can show one day, month or a year period. Time period stipulates the day (days) shown in the graph.

button Previous shifts time period one day backward. With daily time period we can click on back arrow and it shows the previous day etc.
button Scope chooses longer time period. With daily time period we can click on button Scope and the graph shows monthly period. With monthly time period we can click on button Scope and the graph shows annual period.
button Next shifts time period one day forward. With daily time period we can click on forward arrow and it shows the next day etc.

• Since the first day of the time period
• Until the last day of the time period. If it is only one day time period the date in Since and Until boxes is the same.
• Today when you click here the current date is filled in automatically in the Since and Until boxes.
• Month (e.g. January, February…) when you click here the boxes Since the first day of that month and Until the last day of that month are filled in automatically.
• Year ( 2010, 2011…) when you click here the boxes Since the first day of that year and Until the last day of that year are filled in automatically .
  

Green bars in the first graph show the energy produced. Daily graph shows the total of energy produced per hour. Monthly graph shows energy produced per day. Annual graph shows total per each month.

Solar Monitor unit sends the data for graphs. Minimum value to be send is 1kWh. That is why no graph is available on cloudy days, you can see only No data available…report. This report means that less than 1kWh was produced in that particular time period.

The energy produced can be measured by electrometer. This is accurate and favorite option. Second option is getting the values straight from the inverter . But errors can appear due to inverter measuring and loss in the wiring. The measured values are rather inaccurate.

Inverter's values are shown in a line graph. In a daily graph all received data is presented ( in a given period, minimum 5 minutes). With time period longer than 2 days the data is given in arithmetical average per 30 minutes. If presented time period exceeds 30 days the data is given in arithmetical average per 24 hours.

This graph makes it possible to present the values measured by the inverter. You can choose presentation of a particular value in a checkbox Type of graph. Available options: Output and Irradiation, Phase and Total Output, Current, Voltage, Frequency, Temperature. Because the data for this graph come straight from the inverter, only data from your particular inverter is presented, which means that sometimes there will be an empty graph. Irradiation values are given by irradiation sensor.

Second checkbox Inverters enables to choose a particular monitored inverter and presents its graph.
