Schneider C40 Charge Controller 40A, 12/24/48V

C40 Charge Controller, 40A, 12/24/48V

  • The C Series offers three models, the C35, C40, and C60, that can handle 35,40, and 60 amps of DC current.
  • Silent, pulse width modulated (PWM), high efficiency operation.
  • Three-stage battery charging (bulk, absorption, and float).
  • Automatic overload protection in both active and passive modes.
  • PV array short circuit and reverse polarity protection.
  • Durable construction.
  • Backed by a two year warranty.
  • Microprocessor controlled.
  • Energy Type: Wind, Solar, Hydro
  • Works with wind turbines, solar panels and hydro generators

As a Solar Charge Controller

  • When used as a solar charge controller, the C35 and C60 can control 12 or 24 array operation and the C40 can control 12 and 24 VDC array operation.
  • All units offer selectable settings for NiCad, flooded lead acid, gel, or absorbed glass mat batteries.

As a DC Load Controller

  • As a DC load controller, the C Series has a low voltage disconnect warning system and field adjustable set points that govern automatic low and high voltage disconnect.
  • Manual reset switch for emergency low voltage operation.

As a Diversion Load Controller

  • The C Series automatically directs extra power to a dedicated load such as an electric water heater and ensures batteries are never over-charged.


  • Plug-in remote temperature sensor (BTS) for increased charging precision.
  • Cumulative amp-hour meter (CM) that can be installed on the face of the controller, or remotely (CM/R), up to 100 feet (30 m) away.
