WIRING
GND -Negative battery terminal
+BAT -Positive battery terminal
GND -Negative terminal of the solar panel
(or other source of charging power)
+IN -Positive terminal of the solar panel
(or other source of charging power)
SWITCH SETTINGS
To gain access to the switches, remove the plug-in connectors and the four screws
from the corners of the cover. There is one switch to select between 12 or 24V and
one to select between SLA or Flooded battery.
TEMPERATURE COMPENSATION
The charge controller has built-in temperature compensation. The charger should be
mounted in the battery box near the battery for optimal compensation.
REVERSE BATTERY INDICATOR
If the battery is wired with the positive and negative terminals reversed, the red
Reverse Battery LED will light. The controller is internally protected from damage from
reverse wiring on both the solar and battery terminals, but must be wired correctly to
charge the battery.

The graph above shows a charging cycle typically found when a Lead Acid Battery
has discharged overnight. The red line (upper) indicates the battery terminal voltage
and the green line (lower) indicates the charging current supplied to the battery.
For a SLA battery below 2.13 Volts per cell, the charge controller enters the fast
charge mode. The charger will supply the maximum current possible to the
battery until the terminal voltage reaches 2.45 Volts per cell. As the battery
approaches a fully charged state, the charger enters a compensation charging
mode and the charging current will taper off . When the current reaches a steady
state value, the controller will switch to the fl oat charge mode. The controller
will both supply current to the load and maintain the battery at 2.35 Volts per
cell as long as charging power is available.
For a Flooded battery the above graph also represents the typical relationship
between battery voltage and charging current during a charging cycle. Charge
voltage parameters will be sightly lower than those expressed for SLA Batteries
to minimize electrolyte evaporation.
