Xantrex C40 Solar Charge Controller 40 Amps
About this deal
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.
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. Electronic protection against short-circuit, overload, over-temperature and reverse polarity conditions 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. 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: Xantrex C40 C-40 3-Stage PWM Solar Charge Controller/ Diversion Load Controller, 40 Amp, 12, 24, or 48 Volt
The C40 can 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.Compatible with 12, 24, and 48 volt battery banks (charging/dumping voltage settings are user settable)
