40A 12, 24 & 48V Wind Generator Hydro and Solar C40 Charge Controller

The C40 has long been the mainstay of our charge controller line-up; its versatility and reliability have made it an industry standard. The C40 is joined by two companion controllers, the C35 and the C60. All three fully solid-state, microprocessor-driven controllers are UL and cUL listed. C Series controllers may be configured for PV battery charging, DC load control, or DC diversion operation. Whatever the charging source, a C Series controller is sure to meet your DC controller needs.

40A 12, 24 & 48V Wind Generator Hydro and Solar C40 Charge Controller Features:

  • A Controller for Virtually any DC Charging Source
  • 3-Stage Battery Charging, PWM Charge Performance
  • Best suited for  Wind, Hydro, and Solar Generators 
  • Easy to assemble with detailed instructions
  • DC Load Controller Mode with LED Status Indicator

Package includes:

  • 1x Generator Charge Controller
