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. However if you were to say short out a cell, two, or more with say a wrench slipping while tightening a connection, you would not likely live through it as you and the building would be incinerated. This digital meter only mounts as a remote meter (does not fit on front of charge controller) for the C35, C40, or C60. It displays volts, amps, and resettable cumulative amp hours for a solar array, DC loads, or diversion loads, depending on the application. This CM/R comes with 50’ communication cable for remote installation. The charge controller has an internal relay capable of switching up to 10 amps or 30 amps of wind or solar. Learn about the different models of the Xantrex Freedom SW inverter / chargers. They are pure sine wave 120 Volt AC output (60 hertz) designed for mobile applications like boats or RVs.

I realize this is an older thread, but I have been looking at this myself. I have SE XW+ inverters, 60-150 MPPT charge controllers, battery monitor and ComBox. Obviously the ComBox already provides monitoring plus system configuration and control. But I am interested in collecting the data in an Open Source solution and integrate with Home Automation, etc. 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. C Series controllers all use Pulse Width Modulation (PWM) charging profiles which are designed to provide a full charge to your battery while, at the same time, minimize gassing which can shorten battery life.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. 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. 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? 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.

Don't forget a fuse on your battery, I love the simple and compact MRBF terminal fuse by blue sea (MRBF - Marine Rated Battery Fuse) 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.Hi Calgirl - Look at the Trojan Presentation pdf that Sunking supplied. It is a great document on batteries. Compatible with 12, 24, and 48 volt battery banks (charging/dumping voltage settings are user settable) I feed enmonCMS, but through external sensors, not direct modbus interface - it is pretty accurate, though. All C Series controllers automatically initiate a 3-stage battery charging cycle. 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. C Series controllers are factory set for solar PV battery charging operation.

The C40 has long been the mainstay of Xantrex's charge controllers because of it versatility and reliability. The C40 is a 100% solid state, microprocessor-driven controller which is UL and cUL listed. The C40 controller may be configured for solar panel battery charging, or DC load control (e.g. low voltage disconnect) or DC diversion operation (e.g. wind turbines and hydro generators). Whatever the charging source, the C40 Xantrex Charge Controller is sure to meet your DC controller needs. 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. 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:

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… 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. For additional information on this 40-amp solar charge controller, please see the ./pdf documents below. 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.

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. The C40 automatically initiates a 3-stage battery charging cycle. 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).
