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
temperature compensation and is recommended when
the ambient battery temperature differs from the ambient
controller temperature by more than 5º C. The standard
cable length is 33 ft (10m).
NOTE:
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
information, error indications, and self-diagnostic read-out.
Information is displayed on a backlit 4-digit custom LCD
display. 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.
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, a Modbus TCP/IP server, and a local web page
server. End users can collect information about their off-
grid PV system remotely by bridging MODBUS TCP/IP
requests to serve LiveView pages, or connect with MSView
monitoring software. The EMC-1 supports all products that
have a MeterBus port.
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.
