C12 is for 12 Volt batteries, and is perfect with 1x 100 Watt solar panel
C35 is for 12 and 24 Volt batteries
C40 is for 12, 24, and 48 Volt batteries.
C60 is for 12 and 24 Volt batteries
The Schneider Electric C-35, C-40, and C-60 PWM (pulse width modulated) charge controllers can be used as PV charge controllers in 12-, 24- and 48-volt systems (only the C-40 can be used in 48-volt systems).
This is one of the only charge controllers with a custom setting for Nickel Iron batteries - just clip the R48 Resistor to boost charge voltage!
The C-Series operate in only one mode at a time, so two controllers must be used to provide both PV charge controller and low battery load disconnect.
As DC load controllers they disconnect the load at a user-settable low voltage and reconnect at a higher voltage reconnect point.
As diversion controllers they send excess power to a "dummy load" (such as a water or space heater) to regulate hydroelectric or wind generators.
When used in diversion mode, derate the amperage by 25%.
All Schneider Electric controllers, when used as a charge controller, have field-adjustable bulk and float set points and perform automatic equalization every 30 days or whenever LVD is reached.
Equalization can be manually initiated with automatic shut-off. Order the optional temperature sensor for a more accurate battery charge controller.
The optional LCD digital display shows battery voltage, array amps and watts, cumulative amp-hours and a separately resettable "trip" amp-hour measurement.
The digital display is available for mounting on the front of the charge controller, or with a 50- or 100-foot cable for remote mounting in a double-gang electrical box.

Nickel-Cadmium and Nickel-Iron Batteries
The Xantrex C12 is compatible with Nickel-Cadmium (NiCad) and
Nickel-Iron (NiFe) type batteries, which must be charged to a higher
voltage level to achieve a full charge. To enable use of the C12 with
NiCad batteries, cut the resistor labeled as R36 on the lower left corner
of the C12 circuit board. This adds two volts to the printed scale on the circuit board around the BULK and FLOAT potentiometers.
Adjust the Bulk Charge Voltage to the setting recommended by the battery manufacturer. Remember to add 2 volts to the scale shown when making the adjustment.
Float Voltage settings for NiCad/NiFe batteries should also be set to the battery manufacturer’s recommendations. Remember to add 2 volts to the scale when making the adjustment.
Note: In some applications the BULK voltage setting should be adjusted to a level below the maximum operating voltage of the DC loads.
This may be as low as 15 volts for some types of electronic loads. Check with the manufacturers of the equipment being used
