Introduction
1.0 Introduction
The ME-BMK is a single battery bank amp-hour meter that monitors and provides
important information about the condition of the battery. This information will let
you know how much energy you have available and let you plan your electrical
usage to ensure the battery is not being over-discharged.
The ME-BMK is easy to install and is designed to be networked with a MagnaSine
inverter/charger using the ME-RC remote to display the information about your
battery bank.

Introduction
Why should I use the MagnaSine Battery Monitor? To ensure your batteries
perform satisfactory and have a long life, they need to be properly maintained and
charged. There are several devices that help to determine if the batteries are be-
ingfullycharged,theyare:
• DC Voltmeter: AnaccurateDCvoltmetercanbeusedtomeasure the Open
CircuitVoltage(OCV)acrossthebatteryterminalsandcomparethereadings
withtheOCVvaluesfromthebatterymanufacturer.ADCvoltmeteristheleast
costly, but is also the least accurate and requires the batteries to be at “rest”.
This “rest” requirement means the voltage measurement should only be done
when there is no current moving through the battery for a long period of time
(mostexpertssaya minimum of 1hour).Usinga DC voltmeterwhenthe
batteries are at “rest” is usually impractical, because the batteries are usually
always powering loads or being charged.
• Hydrometer: Agoodhydrometercanbeusedtomeasuretheconcentra-
tion of battery electrolyte in each individual cell and compare these readings
withthespecicgravityvaluesfromthebatterymanufacturer.Ahydrometer
is very accurate, but can be time-consuming and becomes unpleasant when
workingwithsulfuricacid.Ahydrometerwillnotworkwithsealedbatteries.
• Amp-hour Meter:Anamp-hourmeterisanelectronicmeasuringdevice
that uses a precision shunt to calculate the amp-hours going in (charging) and
coming out (discharging) a battery. This meter tracks the amp-hour usage
and compares it against the amp-hour capacity of the battery to determine
itschargecondition.CalculatingAmp-Hoursinvs.Amp-Hoursoutisfairly
accurate,iseasilydisplayed,butdoesn’tprovideanaccurateStateOfCharge
under all charge and discharge conditions.
Theses devices have advantages and disadvantages based on accuracy and ease
of use. The MagnaSine Battery Monitor combines the advantages of these devices
with additional information such as monitoring battery temperature and calculating
batteryefcienciestoprovideaneasyandaccuratemeanstodeterminethebat-
tery’sStateofCharge(SOC)condition.Therefore,ifthebattery’sStateofCharge
is easily determined and accurate, the more likely you will attempt to keep the
batterieschargedandenjoyyourbatterysystemperformance.
What is the difference between Amps and Amp-Hrs? Amps indicate the ow
of current going in or out of the battery. Amp-hours indicate the amount of cur-
rent returned to or removed from thebattery.Amp-hrsareacommonratingused
to calculate the battery’s available capacity. For example, if a constant 3 amperes
whereremovedfroma100AHbatteryeachhour,thebatterybank’scapacitywould
be94AHafter2hours(6amp-hoursless).
To help understand the difference, imagine the battery bank is equivalent to a
water tank. When viewing the amps display, it would be similar to watching a
water gauge.Youcanseethatthewaterisowingalittleoralot,butthisdoesn’t
indicate how much water is left. When viewing the StateOfCharge(SOC)display,
it would be similar to viewing the water tank’s level indicator, which tells you how
much water is left in the tank.
Forexample:Ifyouhavea100litrewatertankandyouremovewaterfromthe
tank with a 10 litre bucket. The water level indicator would show the available
waterhasdecreasedby10%;leaving90%ofthewaterstillavailable.Ifthiswas
a battery bank, then you would know that 10 percent of the battery’s capacity has
beenusedanditsStateofCharge(SOC)isnow90%.

2.2 Installation Procedure
Select a location that is dry and away from extreme temperatures to mount the ME-
BMKSenseModuleandDCshunt;usingthesupplied#8x3/4screws(x4).Allow
ample room to view the LED on the Sense Module, access the screws and bolts on
theshunt;andtoaccesstheterminalblockandtheRJ11port.
CAUTION: Do not mount the ME-BMK sense module in a closed battery
compartment or in an area where water or any other liquid can enter the
ME-BMK sense module and cause shorting or corrosion. The internal circuit
board is conformal coated to help prevent corrosion, but this failure is not
covered by the warranty.
Info: Shunts should be mounted in an area where freely circulating air is
available. For continuous operation, it is recommended that shunts are
notusedatmorethan2/3oftheirratedcurrent.
Ifthisisnotpossible,
adequate forced ventilation should be provided to keep the shunt operat-
ingtemperaturebelow60°C.
CAUTION: Beforebeginningtheinstallation,ensureallACpowerisdis-
connectedfromtheinverter;andallnegativeand positive battery cables
are disconnected from the battery bank.

What is Charge Efciency? When a certain amount of energy is removed or
discharged from the battery, this removed energy will need to be returned to keep
the batteries at a 100% state of charge. As batteries are being charged, they
loseenergy;eitherintheformofheatorwhilegassing.Thislossofenergywhile
charging means the battery will not be fully charged if you only return the current
thatwasremoved.Tocompensateforthebatteriesinefciencieswhilecharging,

If the charge efciency is manually set and inaccurate, the state-of-charge
information would be more inaccurate with every charge. For this reason,
continuallymonitorthe‘AH I/O’ reading under the 03 BM: Meters menu.After

5.0.1 How does the Battery Monitor (ME-BMK) Operate? The ME-BMK battery
monitor uses a precision resistor known as a shunttomeasurecurrentowintoand
out of the battery. The shunt provides a small voltage to the sense module that
isproportionaltothecurrentow.Whencurrentstartsowingintooroutofthe
battery,thesensemodulemeasuresthecurrentowanddeterminestheamount
of current removed from and returned to the battery. The amount of current or
“amp-hours”removedorreturnedisdisplayedontheME-RCremotecontrolasthe

Operation
04 BM: Status - This menu selection displays “read-only” displays that give the
current operating status of the Battery Monitor (BM). This selection also provides
information to know if there is a power-up fault condition.
Figure 5-3, METER: 04 BM: Status Display
• BM: Pwr-up Fault - The BM faulted when it was powered-up; the fault
occurred because the power-up self-test failed. See the Troubleshooting section.
• BM: No Comm - The BM is not communicating with the remote. This typically
means a ME-BMK is not installed in the system. If installed, view the Sense
Module LED and use Table 5-1 to help determine the issue.
• BM
: Ready - The BM is connected and actively monitoring the battery
system.

06 BM: TECH - These menu selections allow you to access system information
used to assist service technicians in troubleshooting the Battery Monitor or the
charging system..

• BM Rev - This “read-only” menu displays the rmware revision level of
the connected Battery Monitor. If the Battery Monitor is not connected or not
communicating, the display will show “0.0”.

• Min DC - This menu displays the lowest battery voltage since the last reset.
The voltage shown on the display is averaged each second and is helpful when
troubleshooting or detecting an over-discharge condition.

• Max DC - This menu displays the highest battery voltage since the last
reset. The voltage shown on the display is averaged each second, this allows
you to check your charging system (battery charger, charge controller, etc.) to
ensure the charging voltage has been attained. This display is also helpful when
troubleshooting or detecting if an over-charge condition has occurred.
