Solar CHarge Controller

I have a Grape Solar GS-MPPT-320W solar charge controller installed in a 2008 Adventurer 33V.
Today I discovered that the entire display is flashing.
Any ideas what that might be?

The Grape Solar GS-MPPT solar charge controler's owners manual has a number of different troubleshooting charts for various issues:
