An amp-hour meter is an electronic measuring device that uses a precision shunt to calculate the amp-hours going in (charging) and coming out (discharging) a.

The Device incorporates a MicroSD card slot which allows using a standard FAT-formatted card to configure it and update its firmware.
At minimum, you should specify drop voltage and maximum current for the connected shunt. In addition, you can specify battery parameters such as nominal capacity and voltage, chemistry, etc.

The Device can be also configured over NMEA 2000 using installation description strings a PC gateway and software (like CAN Log Viewer or ActiSense NMEA Reader) may be required for this method. Device connection (Device's wire colours are in BOLD) A shunt based battery monitor is like an accountant for current going into and out of the battery. The solar charge controller only knows current it is putting into the system. The Battery Monitor can be configured to manage channels of an NMEA 2000 digital switching system, and/or trigger a digital alarm unit compatible with standard NMEA 2000 PGNs 127501/127502. External shunt's nominal voltage drop (recommended): 75 mV Clipper BM-2 Battery MonitorThe BM-2 is designed to monitor performance of 12 volt lead acid battery systems with capacities of up to 600 Amp hours.External shunt rated current: 5.2500 A.For example, you can configure the Battery Monitor to automatically raise a sound or voice alert about low battery charge with the Alarm Button, or to turn some equipment on or off, or to start a genset to recharge the battery with the Circuit Control. It is supplied complete with a precision 200 AMP shunt and a prefabricated cable assembly to enable simple DIY installation. Breakdown voltage between NMEA 2000 network interface and inputs: 2500 V RMS.Maximum allowed DC voltage on inputs (with respect to GND input): 40 V.Current measurement accuracy (see note below): ☐.5 %.The unit continuously monitors voltage, current (charge or discharge.
