Xantrex Charge Controller

April 18, 2006

My new charge controller is here. This is Xantrex C12, a 25 amp version of their C controllers. This particular model features Pulse Wave Modulation (PWM) charging. It has field settings for bulk charging, absorption charging and float charging. It also has settings for automatic equalization (or it can be done manually by pushing a switch). Unique to the C12 is a feature that will turn on 12 volt lights at night, what they call the "nite-lite" feature.

The C12 also has a 12 volt distribution output for running 12 volt appliances up to 25 amps. A good place to order this controller from is Infinigi.com - I've ordered parts and supplies from them and they're very good with customer service.

You can download the specs. or the manual at www.xantrex.com

	Here is how big the controller is. It's about the size of my hand.
	Here are two of the 1/2 inch conduit openings in the unit. There's another one on the back side for wall mounting.
	The guts. You can see the POT settings on the right hand side. There are also test points so you can set the voltages almost exactly where you want them.
