Xantrex C40 Solar Charge Controller 40 Amps

Product Information

When used as a load controller, the C Series will automatically turn a DC load on or off at predetermined battery voltage settings. Both LVD (low voltage disconnect) and LVR (low voltage reconnect) set points are user adjustable. In this mode, all power, which is not used to maintain a full charge on the batteries, is diverted to a load dump such as water or space heaters. Diversion mode is used to regulate microhydro and wind turbine systems which need a constant load. There are a number of field configurable, user adjustments for C Series controllers. The C40 may be configured for 12, 24 or 48 volt systems. Bulk and Float voltage set points are user adjustable which allows use with a wide variety of battery technologies including; flooded lead acid, gel, and absorbed glass mat. In addition, there are manually selectable settings for Nicad batteries.

I feed enmonCMS, but through external sensors, not direct modbus interface - it is pretty accurate, though. Silent Microprocessor Control. All C Series controllers have a powerful microprocessor at their core which increases system performance and maximizes battery life. They are fully solid state and operate silently. In this mode, all power, which is not used to maintain a full charge on the batteries, is diverted to a load dump such as space or water heaters. Diversion mode is used to regulate micro-hydro and wind turbine systems which need a constant load. O.K. let me do some reading on the links and the Sunforce manual. Mike, I had forgotten about the "aging" issue with batteries....thanks for the reminder. Incidentally, I read that you do not equalize AGM batteries....was that wrong? I think my Xantrex C40 manual had that info. A Controller for Virtually any DC Charging Source. 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.

The C40 uses Pulse Width Modulation (PWM) charging profiles which are designed to provide a full charge to your battery while minimize gassing which can shorten battery life. The Xantrex C40 is designed for 40 amps of DC current at 12, 24, or 48Vdc. Considered to be one of the best in the industry, Xantrex Charge Controllers offer a variety of features.A unique feature of the C Series controllers is thier versatility, as they can work as a charge, load or diversion controller. Electronic protection against short-circuit, overload, over-temperature and reverse polarity conditions A simple to read, multi-color LED indicates operating status and is standard on all C Series controllers.

Bulk, Absorption, and Float modes are used to ensure that voltage and current settings accurately match the batteries' actual state of charge. This means fast-as-possible charging and extended battery life. An auto equalize mode can be easily switched off when the controller is used with sealed batteries. (Charge controllers with mechanical relays or solenoids cannot do this).I’m still super interested. Two objectives for me: integrate into my home management system (Vera), and be able to control the solar chargers with a better algorithm than Schneider’s which drives me crazy sometimes - it is so inefficient in using sun hours… Incidentally, I read that you do not equalize AGM batteries....was that wrong? I think my Xantrex C40 manual had that info.

I'm a telephone company retiree and want to do nice cable runs and make everything pretty, don't you know!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? Xantrex C40 C-40 3-Stage PWM Solar Charge Controller/ Diversion Load Controller, 40 Amp, 12, 24, or 48 Volt Xantrex Technology is a world leader in producing advanced power electronic products for the solar and mobile power markets. Xantrex, a subsidiary of Schneider Electric, manufacturers a range of components for the renewable energy, marine and mobile power electrical systems.

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.Compatible with 12, 24, and 48 volt battery banks (charging/dumping voltage settings are user settable) When used as a load controller, the C Series (C40) will automatically turn a DC load on or off at predetermined battery voltage settings. Both LVD (low voltage disconnect) and LVR (low voltage reconnect) set points are user adjustable. I have made some progress on accessing Schneider Electric devices through their Conext ComBox. I have been able to set up an Arduino Uno with Wiznet 5100 Ethernet shield, and utilizing the ArduinoModbus library have been able to query Modbus registers from the SE devices. It is all very simplistic right now, but I am confident that I have all the technical pieces to access any SE device via Modbus over TCP/IP, and feed it to any network service. My next step is to create a simple service running on the Arduino that will query SE devices and produce JSON output.
