The C40 has a powerful microprocessor at its core which increases system performance and maximizes battery life. Xantrex, a subsidiary of Schneider Electric, manufacturers a range of components for the renewable energy, marine and mobile power electrical systems. The optional LCD digital display shows battery voltage, array amps and watts, cumulative amp-hours and a separately resettable "trip" amp-hour measurement. Do you understand the the current involved, size of wiring and breaker requirementsand voltage drop problems for that?

Your two 12 volt 100 amp batteries are no where near enough capacity to operate that inverter to full power.

Wow I would never use more than a 1000 watt inverter on a 12 volt system, even 1000 watts is pushing it. 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. Although this is not an Open Source solution, it does provide a start point that will allow me to begin utilizing emonCMS and learning more about the OEM stack. 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. My next step is to create a simple service running on the Arduino that will query SE devices and produce JSON output.

The C-40 are appropriate for larger systems, and can be used either as either a charge or load controller.and UL 458* with Marine supplement *For marine supplement compliance drip shield in specific mounting orientation is required. Brushing up against them will not hurt you (providing no conductive objects) as each cell is only 2 volts which with 12 in series is 24 volts. If I don't care for solar assist in my home, I will move it to my hobby building and use it to power some of my hobby machines. Xantrex Technology is a world leader in producing advanced power electronic products for the solar and mobile power markets.

Whatever the charging source, the C40 Xantrex Charge Controller is sure to meet your DC controller needs. A unique feature of the C Series controllers is thier versatility, as they can work as a charge, load or diversion controller. I said it was not a good idea because it will just be about impossible to keep them properly equalized. As a Solar Charge Controller- When used as a solar charge controller, the C40 can control 12, 24, or 48Vdc array operation. I feed enmonCMS, but through external sensors, not direct modbus interface - it is pretty accurate, though.

It is capable of handling 40 amps at continuous duty and can handle current surges of up to 85 amps. Furthermore, if you do crack their protections and modify parameters via third party means, it will nullify your warranty.

The majority of Xantrex products are manufactured to serve 12 Volt and 24 Volt DC (direct current) systems that require AC power. The C40 has long been the mainstay of Xantrex's charge controllers because of it versatility and reliability.

I already have a ComBox, so I am setting up an Ubuntu server, install emonCMS and attempt to feed Modbus data via TCP/IP. The ProSine is UL 458 listed for mobile applications (RVs or boats) and UL 1741 for homes in the United States.
