2.4 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 +/- 5º C or more.
An RTS can be attached to the ProStar at any time.
The ProStar will automatically use the RTS for battery
temperature compensation when installed. The stan
dard cable length is 33 ft (10m), and can be extended
to 100 ft (30m) if required. Installation instructions are
provided with the RTS.

NOTE: The use of a Remote Temperature
Sensor (RTS) is strongly recommended.
Controller location, air flow, and system power can
drastically affect the local temperature sensor reading.
An RTS will provide optimal charging performance.
RM-1 Meter
A remote meter for monitoring system variables,
for use through the ProStar Meterbus port.
RelayDriver (RD-1)
The Relay DriverTM accessory enables the ProStar
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
For more information on the Relay Driver, visit our
website at www.morningstarcorp.com, or inquire with
your local Morningstar dealer.
Ground-fault Protection Device (GFPD-150V)
The GFPD-150V detects power source ground faults
and interrupts current as required by the US National
Electrical Code.
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.
TM
PC MeterBus Adapter
(Model: MSC)
The MSC converts the MeterBus RJ-11 electrical
interface to an isolated standard RS-232 interface
which enables communication between the
ProStar and a PC.
The MSC can be used for
programming custom charging set-points, and for
logging data in MSView. See Section 4.5 for more
information on programming.

3.0 INSTALLATION INSTRUCTIONS
3.1 General Installation Notes
• Read through the entire installation section first
before beginning installation.
• Do not install in locations where water can enter
the controller.
• Loose power connections and/or corroded wires
may result in resistive connections that melt wire
insulation, burn surrounding materials, or even
cause fire. Ensure tight connections and use cable
clamps to secure cables and prevent them from
swaying in mobile applications.
• Preset charging profiles are generally designed for
lead acid batteries. Custom settings can be used
for varied charging requirements (see sections 3.2
and 4.5 for details). Note that some battery types
may not be compatible.
• The ProStar battery connection may be wired to
one battery or a bank of batteries. The following
instructions refer to a singular battery, but it is
implied that the battery connection can be made
to either one battery or a group of batteries in a
battery bank.
• The ProStar uses stainless steel fasteners, an
anodized aluminum heat sink, and conformal
coating to protect it from harsh conditions.
However, for acceptable service life, extreme
temperatures and marine environments should be
avoided.
• The ProStar prevents reverse current leakage at
night, so a blocking diode is not required in the
system.
• The ProStar is designed to regulate ONLY solar
(photovoltaic) power. Connection to any other type
of power source e.g. wind turbine or generator may
void the warranty. However, other power sources
may be connected directly to the battery.
• The connector terminals will accept a maximum
wire size of AWG #6 / 16 mm2 (solid/multi-strand)
or #8 AWG / 10 mm
flathead screwdriver, and torque tightly up to 35
in-lb.
• Stranded wires to be connected to the ProStar
terminals should be prepared first with e.g.
clamped copper heads, etc. to avoid the
possibility of conductor strands coming free out of
the connection screw, and possible contact with the
metal enclosure.
WARNING: Solar and battery fuses or DC
breakers are required in the system. These
protection devices are external to the ProStar
controller, and must be a maximum of 20 Amps for the
ProStar-15/M, and 50 Amps for the ProStar-30/M.
WARNING: All breakers must be properly
rated for wire ampacity, which may require
less than the maximum breaker sizes referenced
above.

WARNING: Minimum over-current
protection device interrupt ratings must be
2000A for 12V systems, and 4000A for 24V systems.
NOTE: Carefully observe the LEDs after
each connection. The LEDs will indicate
proper polarity, and a secure co nnection.

Switches 2, 3: System Voltage
Three (3) system voltage configurations are available
as shown in the table below:
NOTE: Before connecting the battery, measure
the open-circuit voltage. It must be over 10
Volts to start the controller. If the system voltage
DIP Settings Switches are set to Auto-detect, battery
voltage over 15.5V will be detected as a 24V nominal
battery, and the unit will charge accordingly. The
12/24V auto selection is only done at start-up, and
the detected system voltage will never change during
operation.
It is recommended to set DIPs 2 and 3 to the correct
system voltage setting. Only use the default autodetect setting if the nominal system voltage is not
known.
Switches 4, 5, 6: Battery Type Selection
Preset ProStar battery charging options are shown
in table 3-1 below. All voltage settings listed are for
nominal 12 Volt batteries. Multiply the voltage settings
by two (2) for 24 Volt systems.
NOTE: The charging profiles below are general
guidelines for use at the operator’s discretion. Consult
the battery manufacturer for optimal battery charge
settings.

3.3 Mounting
Inspect the controller for shipping damage. Mount the
ProStar to a vertical surface (4-#8 stainless steel selftapping screws are included). Tighten the mounting
screws using care not to crack the plastic case. Do not
install directly over an easily combustible surface since
the heat sink may get hot under certain operating
conditions.
NOTE: The heat sink must be in a vertical
position (fins up and down).
For proper air flow, allow at least 15 cm (6 in) of space
above and below the controller, and 50 mm (2 in) at
the sides - see Figure 3-2 below. Install in an area
protected from direct rain and direct sun.
If the controller is installed in an enclosure, some
ventilation is recommended. Do not locate in an
enclosure where battery gases can accumulate.
3.0
The default (PWM) switching setting (OFF / down) operates
at 300Hz. If load or system noise is an issue, DIP 8 can be set
(ON-up) for slow switching at 1Hz. Standard PWM switching is
recommended when system noise is not a problem.
