This Battery Monitor Measures:
Battery Volts, Amps, Amp-Hours, Battery Percent Full, and Five Other Data Functions
Size : 4.5 x 4.75 inches.
Shown in optional "double gang" box.
If your home, R/V or boat depends on batteries for electrical power, here's why a battery monitor should be part of your electrical system.
|CONSERVATION||BATTERY CARE||SYSTEM MAINTENANCE|
Helps save valuable energy by letting you see how much you're using
Provides information you need to protect your battery investment.
Helps locate system problems when they occur.
"BATTERY PERCENT FULL" display shows how full the battery is by the most accurate method: measuring amp hours expressed as a percentage of a full battery.
AMP HOURS FROM FULL shows how much energy has been taken out of a full battery.
EASY TO UNDERSTAND FRONT PANEL AND CONTROLS All display and RESET functions are explained on panel. The six less used functions are easy to access, yet easy to ignore if not needed.

MAIN DATA FUNCTIONS
Push SELECT to cycle through these:
Battery Volts: Reads 8.0 - 35.0 volts accurate to ±.08 volt including "digit resolution" accuracy. An optional adapter extends this to 70 volts for 32 or 48V systems and delivers lightning protection too. Please see accessory section for additional information.
Battery Amps: Measures amps into and out of battery, accurate to ±1% ±1 least significant digit. Or the meter may be set up to measure only incoming amps from solar array or other energy source, or only load amps if desired. Resolution and maximum amps depends on choice of shunt. With the 100A/100mV shunt: measures 0.01 to 250 amps. With 500A/50mV shunt: measures from 0.1 to 1000 amps. Shunt type is programmable, so amps always display correctly. Speed of response one second time constant.
Battery Percent Full: This number is based on net-amp hour reading divided by the user programmable value of battery capacity. This is more reliable than other methods which do not use amp hours to compute battery energy content (for example less expensive monitors which rely only on battery voltage to estimate energy content). There is a (user programmable) choice of two ways to display this result: (1) an exact, literal reading from 0-100% in increments of 1%, or (2) a more "honest" display which shows in steps of 5%, and displays "FUL" when above 92%, and "LO" when below 27%. Although the meter amp hour measurement accuracy is ±1%, this option is intended to reflect the fact that the system accuracy in determining how much energy content in an actual battery system, (assuming the batteries are recharged fully at least every week) is more honestly stated as ±5%. The assumed BATTERY CAPACITY, upon which this display is based, can be programmed from 10-2550 amp hours, in increments of 10 amp hours.
Display Off: The display may be turned off (for lowest current draw of 16 ma.
How the TriMetric Determines that Batteries are Charged: When the TriMetric senses that batteries are charged, it resets the "days since charged" display to 0.00 and (at user option) resets the "amp hours" to 0.00 and the "Battery % Full" to 100%. The TriMetric determines that the batteries are "charged" when the battery voltage rises above a user programmed "charged voltage" (adjustable from 10.0-35.0 volts within 0.1 volt) and the charging amps goes below a user programmable "charge current criteria" (adjustable from 1-100 amps within 1 amp). This condition must remain for 20 seconds.
User Selectable Efficiency Factor: Amp hours may be monitored without an "efficiency factor," meaning that the "charge" and "discharge" current for the "net amp hours" reading are both accumulated at exactly 100% rate. Or a "charge efficiency" factor may be manually set from 60% to 100% in 1% increments. This means that the discharging current will subtract from amp hours at 100% rate, where as the charging current accumulates at the lower specified rate, to approximate the "charge efficiency" of the battery. This compensates for the fact that you don't get quite as much charge out of a battery as you put in.
The Same Reliable, Proven Measurement Circuit: This TriMetric Battery Monitor circuit has proven accurate and reliable for over three years in production. All programmed information retained when meter unpowered.
Remote Locatable: Up to 55 feet with four #22 ga. wires. Up to 150 feet with #18 wire. Longer distances are possible with larger wire size.
Bright Display With Low Current Draw: Requires about 30mA with display on-about 16mA with display off.
Size: The battery monitor is designed to fit into a standard "double-gang" electrical box mounted 90 degrees from the usual position. See accessories section (on the back) for suitable enclosure. Panel size (inches): 41/2 x 43/4 x 13/4 deep.
Warranty: The Bogart Engineering warranty policy is to repair at no cost any of their products that develop a problem not due to customer misuse.

I installed one in my RV that has 3 solar panels. Now I know just what my panels and batteries are doing! This unit tells a lot of info about the whole system. No more problems when dry camping. Great thing to have.
