In the FreeWave Portal, you can navigate to your list of Fusion Mini's and beside the name of the Mini, you'll see the Device Power Performance graph link.

Clicking in that will bring you to the graph.

By default, you will be shown the graph for Today. Depending on the time of day and the number of messages received, may see a small graph.

You can use the menu at the top right to select between Today and the last 7/15/30 days.

Selecting another time period will extend the graph.

In the above graph there are distinct colors that refer to the following:

• Darker green bars - These are the current battery level in Volts
• Light green sections - These are the period when the battery is charging
• Blue - this is the charge voltage on the panel

When the blue line is above 16.5V, the battery will charge. 

Note: If the ambient temperature is above the limit, the battery will not charge despite the graph indicating it is charging.
