Charge Controllers

Do you need a charge controller – the simple answer is yes! Charge controllers are devices used to protect batteries from damage due to overcharging. They limit the voltage and current delivered to a battery by solar, wind or microhydro generation.

Modern day controllers with sophisticated microprocessor-based circuitry have all but replaced the older on / off type controllers. When choosing a charge controller for your system keep in mind that you may want to expand your charging capability in the future. A larger controller may be a wise investment.
 
Xantrex C35 - 35 Amp, 12/24V Controller
The C35 controller is a 3-stage PWM controller. It can operate as a charge controller or a load controller, but not at the same time. The C35 can be used in 12V or 24V systems, while the C40 can be used in 12V, 24V or 48V systems. C35 controllers can even be used as a diversion regulator for hydro and wind systems by sending excess power to an external heating element if the batteries are full.

Xantrex also offers an optional battery temperature sensor (15’ or 35’) as well as a very handy ...
