2.5 Optional Accessories
The following accessories are available for purchase
separately from your authorized Morningstar dealer:
Remote Temperature Sensor (Model: RTS)
The RTS measures battery temperature for accurate temper-
ature compensation and is recommended when the ambi-
ent battery temperature differs from the ambient controller
temperature by more than 5º C. The standard cable length
is 33 ft (10m).
N
OTE:
The use of a Remote Temperature Sensor is
strongly recommended. Controller location, air flow, and
system power can drastically affect the local temperature sensor
reading. An RTS will provide optimal charg
ing performance.
RM-1 Meter
The digital Remote Meter displays system operating in-
formation, error indications, and self-diagnostic read-out.
Information is displayed on a backlit 4-digit custom LCD dis-
play. The large numerical display and icons are easy to read
and large buttons make navigating the meter menus easy.
Additionally, a status LED and three (3) battery SOC LEDs
provide system status at a glance.
The meter can be flush mounted in a wall or surface
mounted using the mounting frame (included). The RM-1 is
supplied with 33 ft (10.0 m) of cable, a mounting frame, and
mounting screws. The RM-1 connects to the RJ- 11 Meter
port on the ProStar MPPT.
RelayDriver (RD-1)
The Relay Driver
TM
accessory enables the ProStar MPPT to
control external devices. Four (4) relay control ports can be
configured (in various combinations) to perform the
following tasks:
• generator control (2, 3, and 4-wire configurations)
• dry contacts for alarms and other signals
• advanced load control
• vent fan control
• DIN rail compatible or surface mount
Ground-fault Protection Device (GFPD-150V)
The GFPD-150V detects power source ground faults
and interrupts current as required by the U.S. National
Electrical Code.
Wire Box for ProStar MPPT
A modular wiring box that can be added to any version of
ProStar MPPT controller. The box acts as a junction (using
knock-outs) to run controller wiring to external conduit, if
desired. The wire box cannot be used with rigid conduit.
The communications accessories / adaptors below should
be housed in the Wire Box for ProStar MPPT.
Communications Support:
Ethernet MeterBus Converter (EMC-1)
This product is an Ethernet gateway that provides web
monitoring services, a Modbus TCP/IP server, and a local
web page server. End users can collect information about
their off-grid PV system remotely. One EMC-1 supports all
products with MeterBus ports by bridging MODBUS TCP/IP
requests to serve LiveView pages for each product.
USB Communications Adapter (UMC-1)
A modular unit that uses a USB-B plug, usually from a USB
A-B computer cable, and an RJ-11 plug to connect with a
Morningstar controller's MeterBus port, for monitoring and
programming using MSView PC software.
PC MeterBus Adapter
TM
(Model: MSC)
The MSC converts the MeterBus RJ-11 electrical interface
to an isolated standard RS-232 interface which enables
communication between the ProStar MPPT and a personal
computer (PC). The MSC can be used for programming
custom charging set-points, and for logging data in MSView.
See Section 4.7 for more information on programming.
