DataLog Screen
From the Charge Controller Error screen, the <DataLog> soft key proceeds to the Charge Controller
Datalog screen. This screen shows accumulated daily amp-hour and watt-hour statistics, as well as
maximum current, wattage, and maximum and minimum voltage figures. These maintain a continuous
daily log, up to 128 days, which can be recalled. One day can be displayed at a time.
IMPORTANT:
If two or more charge controllers are used in the same system and are started or
cleared on different days, their numeric dates will not be the same. This can lead to some
misunderstandings when looking back and comparing data between the two or more units.
A user looking back at day 12 on both units would find very different results.

It extends back by 128 days before stopping.
