A2 Installing a Battery Monitor
Figure A2-1, Accessing the DC Shunt
Magnum Panels are factory equipped with a DC shunt (Item 31, Figure 2-7 and 2-8; Item 29 Figure
2-9; or Item 30, Figure 2-10b). This allows a battery monitor to be easily wired.
Magnum Energy’s ME-BMK-NS (Battery Monitor Kit - No Shunt) is a battery bank amp-hour meter
that provides important information about the condition of the battery bank. This information
will let you know how much energy you have available, and let you plan your electrical usage to
ensure the batteries are not being over-discharged. Using a Magnum remote/display, you will be
able to see the percentage state of charge, real time amps, voltage, amp-hours in/out, and the
minimum/maximum DC volts. The Battery Monitor Kit includes the sense module, sense wires
and a network cable.
The MP enclosures provide two mounting dimples installed with #8-32 x 1/2” (T20 drive) Torx
screws. This allows the sense module (part of the ME-BMK-NS) to be easily installed inside the MP
enclosure (as shown in Figure A2-3). Once the sense module is installed, wire the sense wires and
module to the DC shunt by removing the Shunt Access Plate on the right side of the MP enclosure.
See Figure A2-2 and A2-4 for information on wiring the ME-BMK-NS.
