Why is the average battery energy consumed value much less than the battery capacity?
This usually happens when there is a lot of load, and not enough solar energy to charge up the battery in bad months. To check,
go to Reports > Design Review page
on the Average Daily Performance chart, select a week view in the best solar month, and then a week view in the worst solar month.
Click ‘State of Charge’ in the chart legend to display it.
In this example, we can see that the battery gets a good cycle every day in January:
But in July there isn’t enough solar energy to charge the battery:
You could consider adding more panels or recommending the customer reduce the winter energy consumption. Or grid charge during off peak in the winter, but that rarely pays for itself.
