2.5 Optional Accessories
The following accessories are available for purchase separately from your authorized Morningstar
dealer:
TriStar Digital Meter 2 / TriStar Remote Meter 2 (Models: TS-M-2 / TS-RM-2)
The TriStar Digital Meter mounts directly on the TS-MPPT controller, replacing the wiring box cover.
The TriStar Remote Meter can be ush mounted in a wall or into a standard duplex (2-gang) electri-
cal box. A 2 x 16 character display shows system operating information, error indications, and self-
diagnostic information. Four (4) buttons make navigating the meter menus easy. For systems where
multiple TS-MPPT controllers are networked together, one (1) meter can display full system informa-
tion. The TriStar meters connect to the RJ- 11 MeterBus
TM
port on the TriStar-MPPT.
Meter Hub (HUB-1)
A Morningstar MeterBus
TM
network with multiple controllers requires a Meter Hub for electrical
isolation. The HUB-1 allows communication between MeterBus
TM
compatible Morningstar products,
including the TriStar MPPT 150V controller. DIN rail compatible. See section 5.2 for more details.
Relay Driver (RD-1)
The Relay Driver
TM
accessory enables the TriStar MPPT 150V to control external devices. Four (4)
relay control ports can be congured (in various combinations) to perform the following tasks:
• generator control (2-, 3-, and 4-wire congurations)
• dry contacts for alarms and other signals
• advanced load control
• vent fan control
• DIN rail compatible or surface mount
For more information on the Relay Driver, visit our website at www.morningstarcorp.com or inquire
with your local Morningstar dealer.
EIA-485 / RS-232 Communications Adapter (RSC-1)
Connect one or more TriStar MPPT 150V controllers to a PC or to other serial devices using the RSC-
1 EIA-485 adapter. The adapter converts an RS-232 serial interface to EIA-485 compliant signals. An
LED shows network activity and errors. DIN rail compatible.
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 AdapterTM (Model: MSC)
The MSC converts the MeterBus RJ-11 electrical interface to an isolated standard RS-232 interface
which enables communication between the High-Power 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.
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 o-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.
Remote Temperature Sensor (Model: RTS)
The RTS measures battery temperature for accurate temperature compensation and is recommended
when the ambient battery temperature diers 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 ow, and system power can drastically aect the
local temperature sensor reading. An RTS will provide optimal charging performance.
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.
