4.3.4. Other charge algorithm related settings

Absorption time: default 8 hours
Temperature compensation: default -2,7 mV/° C per cell (-65 mV/° C for a 48V lead-acid battery)
Equalisation:
Some manufacturers of VRLA (Valve Regulated Lead-Acid: i.e. Gel or AGM) batteries recommend a
short equalization period, most do not. Most manufacturers of flooded batteries recommend periodic
equalization.
Please see table 5 for more adjustable parameters.
Note about service life of lead-acid batteries
- Flat plate VRLA batteries (i. e. all 6V and 12V VRLA batteries) as well as flat plate flooded
batteries for automotive application deteriorate quickly when discharged by more than 50%,
especially when left in discharged state for hours or days. We therefore recommend not to
discharge by more than 50% and recharge immediately after a deep discharge.
- All lead acid batteries will deteriorate if not fully charged from time to time.

4.4 Connecting the solar array

After the correct charge algorithm has been selected, the controller is ready for use.
Other settings may be changed/entered before or after connecting the solar array.
Close the connection to the solar array.
If there is sufficient sunlight, the charger will automatically start charging the battery.
If, despite sufficient sunlight, the PV voltage reads 000V, please check the polarity of the PV
cable connection.

Table 4: scrolling through the LCD screens
Pressing the "-" button or the "+"button for 4 seconds activates the auto-scroll-mode.
Now all LCD-screens will pop-up one by one with short intervals.
The auto-scroll-mode can be stopped by pressing the "-" or the "+" button shortly.
Backlight: The LCD backlight will slowly fade one minute after pressing one off the buttons.
