Electronic protection against short-circuit, overload, over-temperature and reverse polarity conditions The Xantrex C40 charge controller by Schneider Electric is essential for prolonging battery life by providing a controlled charge to the battery bank without overcharging. As long as the area has ventilation it will be fine. Hydrogen does not reach combustion until the air reaches 4% saturation minimum.

I appreciate all the help fellas.......down the road, I want to hook up the refrigerator and microwave, computer, coffee pot, a room AC, and even the forced air AC (if I can get away with it) .etc.....that's why I bought such a large inverter. Maybe I should wait to hook everything up until I have a larger battery bank and many more panels. My plan was to add to the system as I go along.......but, at least with the batteries, that's not feasible unless I want to take the loss (thanks again, Mike). I want to be prepared incase all hell breaks loose in America not to mention the environment and hurricanes. I'm a retired Mtce. Crew Supv....was a Operating Room Nurse but got tired of freezing to death all day...so went to work for telco as a mtce. splicer.See our video for a brief overview of the Xantrex Product Line. We cover everything from the Xantrex power inverter to their line of battery chargers. The C-40 are appropriate for larger systems, and can be used either as either a charge or load controller. The Xantrex C-40 and C-60 include adjustable set points, over current protection and manual or auto equalize mode. The DVM (Digital Voltage Meter) option adds a digital display of battery voltage, charge current and cumulative amp hours from the solar array. The optional BTS (Battery Temperature Sensor) adds temperature compensation to any of these regulators. Features: Time-tested and reliable PWM solar battery charging ensures long battery life. This charge controller's easy installation is ideal for solar battery charging systems in any enclosed location. As a Solar Charge Controller- When used as a solar charge controller, the C40 can control 12, 24, or 48Vdc array operation. All units offer selectable settings for NiCad, flooded lead acid, gel, or absorbed glass mat batteries. QUOTE=Sunking;17599]OK I am a PPE from the Telco world. So you ought to smell a rat when you look at the suggested cable sizes in the manual. #1 AWG for a 375 amp circuit. Anything sound fishy about that?QUOTE]

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

The Xantex C40 is a fully solid state, microprocessor-driven controllers that is UL and cUL listed. The C Series, Xantrex C40 charge controller may be configured for 12, 24, or 48 VDC operation. It can be used as a battery charge, DC load control or DC diversion operation and comes with a standard multi-color charge status LED.
