A-2 Optional Equipment and Accessories
The following Magnum Energy components are available for use with the RD-E Series inverter/
charger. Some of these items are required depending upon the intended use of the inverter.
MMP Series Enclosures
The MMP175-30D, MMP175-60S, MMP250-30D, and MMP250-60S enclosures are for single in-
verter applications. The MMP Series enclosures have been speci
fi
cally designed to combine all of
the major components required for a renewable energy system — inverter/battery disconnect,
AC overcurrent protection, grounding connections, and a full system inverter bypass switch as
a convenient way to isolate the inverter for battery maintenance — into a single, easy to install
pre-wired enclosure.
Smart Battery Combiner
The Smart Battery Combiner (ME-SBC
TM
) is designed to monitor and charge a second battery us-
ing a portion of the current that is charging the main battery. The ME-SBC eliminates a signi
fi
cant
voltage drop, and provides automatic turn-on and turn-off based on adjustable voltage set-points.
This allows different batteries to be charged from a single charging source, and prevents over-
charging/undercharging.
Remote Switch Adapters
The ME-RSA
TM
and ME-RSA-M
TM
pigtail adapters allow the inverter to be remotely switched on and
off – with or without the ME-RC50 remote display.
Basic Remote Control
The ME-RC50 Remote Control Panel is simple to use; an LCD screen and “at a glance” LEDs
display complete inverter/charger status. Soft keys provide simple access to menus and a rotary
encoder knob allows you to scroll through and select a wide range of settings such as Inverter
ON/OFF, Charger ON/OFF, Utility Power Breaker Setting, AGS Control, Meter Button, Setup and
Tech menus.
Advanced Remote Control
The ME-ARC50 Remote Control Panel uses an LCD screen and “at a glance” LEDs to provide
operating information and allow advanced features to be con
fi
gured (requires Magnum inverters
with advanced con
fi
gurable features). This LCD remote control also provides advanced monitoring/
troubleshooting and includes a FAVS button to access your favorite features quickly.
Auto Generator Start Controller
The ME-AGS-N Automatic Generator Start controller (Network version) is designed to automatically
start your generator based on low battery condition or high temperature.
The AGS controller
includes an input voltage jumper (for 12, 24, and 48 volt battery banks) and a 4-position DIP
(Dual In-line Package) switch which provides the ability to change the relay timing con
fi
gurations
to allow compatibility with a wider range of generators.
Adjustable settings when using the ME-
ARC50 include starting the generator based on: Battery Voltage, Time Of Day, Battery ‘State of
Charge’ or High Temperature.
Battery Monitor Kit
The ME-BMK Battery Monitor Kit is a single battery bank amp-hour meter
that monitors the condition
of the battery and provides information to 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-
NS version does not include
a DC shunt – order the ME-BMK to receive a 500A/50mv DC shunt.
Fuse Block/Fuses
The Magnum Fuse/Fuse-blocks are used to protect the battery bank, inverter, and cables from
damage caused by DC short circuits and overloads. They include a slow-blow fuse with mounting
block and protective cover. The 125 and 200 amp models use an ANL type fuse and the 300 and
400 amp models use a Class-T fuse.
