  • Sample Northern Reliability Customer Performance Monitor (CPM) tool (Figure 1)

    Sample Northern Reliability Customer Performance Monitor (CPM) tool (Figure 1)Using a data collection device in our SC series controllers, Northern Reliability has the ability to collect pertinent data points at predetermined intervals.Our data collection capabilities allow us to map, trend and alarm all of the parameters that are critical to the optimum performance of the system. Data is collected from the SC-100, inverter, charge controller, battery, environmental systems and loads at a frequency of one minute intervals and written to a data base. Files are uploaded from the system on a once per fifteen minute interval basis using a user ID/Password protected cellular modem. The uploaded files are then written to a web enabled application that is also user ID and password protected. Since the web application is “read only” the system being monitored is protected from outside interference.
  • Asset Management Feature - Google Maps Interface (Figure 2)

    Asset Management Feature - Google Maps Interface (Figure 2)By clicking on the hyperlink shown next to the longitude and latitude on the system home page a user can determine the exact location of the system. By embedding the Google API the user can now take advantage of the features and functionality available in the traditional suite of Google applications. Figure 2, shown above, portrays the exact location of the DES relative to the home. From an asset management perspective, the directions feature associated with the Google app allows for service personnel new to the area to get step by step driving or walking directions to the site.
  • Quick Summary Dashboard (Figure 3)

    Quick Summary Dashboard (Figure 3)The graphic displayed above in Figure 3 entitled “Sample Quick Summary Dashboard” portrays a number of system parameters that may be of interest to the user. The system parameters can be displayed in a more tabular or numerical format that enables the user to view exact system parameters.In addition to trending and event logging, critical parameters include items such as battery voltage, battery temp, and battery state of charge can be monitored. The latter being useful in the event of a power outage or system emergency, one can gauge remotely the expected run-time of the system given the load.
  • Event Log + Alarm Status Page (Figure 4)

    Event Log + Alarm Status Page (Figure 4)The sample graphic in figure 4 above is the event log summary page and alarm + status indicator from the DES. The event tab is currently configured to capture anything that may happen on the project. As you can see we monitor items such as the door being open as well as the connection status to the utility. The last refresh date and time is shown on the first line of the graphic. The word values are obtained from the controller interface monitoring the DES system. System parameters are input by the DES operator at time of commissioning, and managed on a continuous basis. Data capture rates are set at one minute intervals and refreshed to the SQL cloud data base at a frequency of every fifteen minutes. Currently the values are identified by the tag name assignment in the controller, which is why they may appear somewhat cryptic.Should a value fall outside of those parameters, the controller will indicate an alarm and the “Green Light” value shown in Figure 1 will change to red indicating the presence of an alarm. The alarm status page will then change to display what value is outside of normal operating parameters. If the site has internet access, an e-mail of the alarm is generated and sent to the system administrator.
  • Trend Comparison (Figure 5)

    Trend Comparison (Figure 5)Our trend screen allows the user to compare and contrast two separate tags and how they performed over the previous 24 hours. The graphic above in Figure 5 shows the comparison between the temperatures inside versus outside of the power equipment shelter. The critical items shown on left side of Figure 5 are presently available for comparison, but the trend comparison can be made from any two values of interest that are captured by the SC-100 controller.
  • Power Data (Figure 6)

    Power Data (Figure 6)The power data graphic shown above in Figure 6 outlines the dynamic of the system. The green line represents the customer load on the critical load panel. The red line represents power being drawn from the grid or power being exported to the grid. All values are shown in watts. If the red line value portrayed is below the 0 on the X axis, the load is being met entirely by the grid. If the red line value portrayed is above 0 on the X axis, power is being exported from the DES to the load. If the red line is higher than the green line that indicates that excess energy is being exported to meet other power needs in the home. If power needs for the balance of the home are less than the excess energy portrayed by the red line, the home is exporting power to the grid and the customer may be realizing some benefits of the net metering program.
  • Inverter Data (Figure 7)

    Inverter Data (Figure 7)Figure 7 portrays the data of most interest to a utility type of client. This graphic shows the current data from the power meter and the cumulative power data for the 24 hour period ending at midnight the day before. The system is presently operating in solar mode, meaning that the total load of the critical panel was 4.32 kWhrs, yet the utility draw was 2.1 kWhrs. The difference between the two values (2.22 kWhrs) was the energy provided by the battery or solar attribute associated with the system.*Note the power meter data referenced above is the meter installed within the DES system.

Data Monitoring Overview

NRI's technology allows us to remotely manage system functions including “Grid Zero” or “Sell Back”. The Grid Zero function is intended to draw no power from the grid and supply the load from solar or battery energy. The Sell Back function is similar to that of a traditional net metered photovoltaic systems. Individually these features and functionality create a significant impact to the utility company grid infrastructure. If deployed in aggregate, these functions also help to improve more efficient grid management.
