Yearly Logs
To view the yearly logs, go to Setup > Harvest Logs. From the Yearly Logs
screen, press Enter. Press the down arrow button to scroll through the yearly
logs, starting with the current year. The charge controller stores up to 12 yearly
logs. After 12 years, the oldest yearly log is overwritten.
Equalizing Batteries
Equalization charging is the process of deliberately charging a battery or battery
bank at a high voltage for a set period of time. Equalize charging remixes the
electrolyte, helps to remove sulfate buildup on the battery plates, and balances
the charge of individual cells.
Make sure to read all cautions and warnings regarding equalization charging
batteries before allowing an equalization charge to occur.
NOTE
In a system where more than one device is capable of equalizing batteries
(such as a system including multiple charge controllers and Conext XW+
Inverter/Chargers), there is no system-wide equalization command for all
devices. To equalize with multiple devices, each would have to be enabled
individually. Alternatively, equalization can be performed using only one
device. During the equalization process, one device applies the equalization
charge while the other devices continue to operate in synchronized charge
mode, typically in float (three-stage charging) or no float (two-stage charging).
WARNING
HAZARD OF EXPLOSION
Equalization charging generates explosive gases which might escape from
the battery. Make sure adequate ventilation is provided. Never leave a battery
unattended during equalization. Follow the battery manufacturer's
recommended actions for determining the appropriate point at which to stop
the equalization process, for example, by monitoring electrolyte specific
gravity.
Failure to follow these instructions can result in death or serious injury.
