Automatic Equalization Mode
To enable an automatic equalization mode, an interval must be set for the number of days to pass between
equalization cycles. This interval can be between 1 to 250 days. The default equalization interval setting is 000
which disables this feature.
The Equalization Interval screen allows the user to set the interval between equalization cycles. It also displays
how many days of the interval has passed. The COUNT value will be cleared to 000 when an equalization cycle is
started, manually stopped, or if the charge controller has been powered off.
