3. HISTORY - Thirty-day Graphic

In this section:
VC_-_History.png

(The fragmented square icon (top left) allows you to toggle between 'portrait' and 'landscape' screen presentations.)

A summary of activity for the last 30 days is presented graphically. Swipe the bar left or right to show any of the previous 30 days.

The daily log shows:

  • Yield: The energy converted for that day.

  • P max: The maximum power recorded during the day.

  • V max: The highest voltage from the PV array during the day.

Clicking on any day/bar in the graph will expand the information to show charge-status times - both as hrs/m; and also as a percentage of the 'charge' day. This graphic provides an at-a-glance representation of how much time your charger is spending in each of three modes: Bulk / Absorption / Float.

Tip! You can use the charge times to see if the PV array is properly sized for your requirements. A system which never reaches 'Float' may need more panels; or perhaps the load could be reduced?

It is also possible to see a specific yield, maximum power, and maximum voltage for the individual trackers by selecting the tracker tab in the history view (number of trackers vary by model -see product datasheet).



It is possible to export the history as a comma separated file (.csv) by clicking the three connected dots at the top right of the history screen:

Battery Voltage

The first figure shows the maximum battery voltage for the day …the figure below is the minimum battery voltage.

Errors

Shows the number of errors (if any) for the day, to see the error codes click on the orange point. See MPPT Solar Charger Error Codes. (You may need to slide the display on your device up to see the errors.)

Total

This shows the total energy converted by the installation and is not re-settable.

Since Cleared

This shows how much energy has been converted by the installation since the last reset.
