Introduction

1.0 Introduction

The ME-BMK is a single battery bank amp-hour meter

that monitors and pro-

vides important information about the condition of the battery. This informa-

tion 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 Magnum

Energy inverter/charger using the ME-RC remote to display the information

about your battery bank.

1.1 Product Features

•  Compatible with 12, 24 or 48 volt systems
•  One adjustable setting - very easy setup
•  All battery meter and Magnum inverter/charger set-up and moni-

toring features in a single convenient display – doesn’t require

multiple displays for inverter and battery system information

• Displays reliable and pertinent information; such as:

Battery State of Charge
Battery Voltage
Battery Current

• Auto-detecting input voltage
• Temperature and battery bank capacity automatically compensated

and coordinated between inverter and battery monitor

• Precision 500A/50mv DC shunt (included in ME-BMK)
• Automatic ef

ciency detection

1.2 Identifi cation and Compatibility

The ME-BMK is compatible with all Magnum inverter/chargers provided with

a ‘Magnum Net’ or ‘Network’ port (i.e. ME, MS and RD Series). The ME-BMK

requires a ME-RC remote display with revision 2.0 or higher to access the

available settings and features of the ME-BMK.

Info:

You can view the ME-RC revision level when you

rst power-

up the remote or by pushing the TECH button and accessing the

Revisions

menu.

If the ME-RC remote revision is not 2.0 or higher, refer to one of the two op-

tions below to obtain the required revision.

1) If the ME-BMK is being installed at the same time as a newly purchased

Magnum Inverter and ME-RC remote system; contact your Magnum Energy

dealer to obtain the ME-RC with revision 2.0 or higher.

2) If the ME-BMK is being installed into an installation with a previously installed

Magnum inverter and ME-RC remote system; contact Magnum Energy about

ME-RC upgrade options.
