Trace Xantrex Solar Panels Voltage and Load Controller C40

For your solar panels system a Controller for Virtually Any DC Charging Source
The C40 has long been the mainstay of our charge controller line-up, its versatility and reliability have made it an industry standard. Now the C40 is joined by two companion controllers, the C35 and C60.

All three of these fully solid state, microprocessor-driven controllers are UL and cUL listed. C Series controllers may be configured for PV battery charging, or DC load control or DC diversion operation. Whatever the charging source, a C Series controller is sure to meet your DC controller needs.

CM, CMR/50 or CMR/100-A back-lit meter which continuously displays: battery voltage, DC amperage, cumulative amp hours and amp hours since last reset. CM mounts on front of C Series, C35, C40 and C60, charge controllers. The remote meters CMR/50 and CMR/100 use simple telephone type plug-in connectors.
50 ft. (15 m) or 100 ft. (30 m) cable included.

BTS/15 or BTS/35—Monitors battery temperature and adjusts charging voltage for maximum performance. A 15 ft. (4.5 m) or 35 ft. (11 m) cable with standard telephone type connectors is included. For C-12 & C-40 Controllers.

The C12 has a LED status light displaying both charging functions and battery charge state at a glance. This controller is used worldwide in a variety of applications, including remote village lighting systems and automatic outdoor lighting in Africa, Latin America, and Asia. The DC disconnect function of the C12 will disconnect DC loads if batteries reach low-voltage conditions. A simple one-time reconnect turns power back on for ten minutes. An optional temperature sensor for the C12, ensures precise battery charging regardless of battery temperature fluctuations.
