Product 2001712003

I have had this installed and operating for >2 years.  The AH in the upper right shows 999 and the battery is still topping off.  How can I reset this to mid scale.  I have 20 KW of 24V Tesla batteries running this house.  I log the numbers twice a day and the discharge wh and charge wh do not equal out.  The bank is operating normally using just the voltage as a gauge.

Thank you for you attention.
