Morningstar's TriStar PWM charge controllers are three-function
that provides reliable solar battery charging, load control or diversion regulation.
controllers operate in one of these modes at a time and two or more controllers may be
to provide multiple functions.
Rated at up to 60 amps, TriStar charge controllers will function
wide voltage range of 12-48 volts. Multiple TriStar PWM charge
controllers can be run in parallel for larger solar arrays up to 300
or more. Options include an optional meter, remote meter and remote temperature
to better meet the needs of off-grid solar
Large heat sink and conservative design enables operating at full ratings to 140°F. No
need to de-rate.
Ratings to 60A at 48VDC will handle solar arrays up to 4kW.
RS-232 connects to a personal computer for custom settings, data logging and remote
monitoring and control.
The TriStar TS-45 & TS-60 are often chosen because they produce low
telecom radio noise. These models are available for our remote solar systems.
DIP switch provides users with a choice of 7 different digital presets and custom settings
Extensive Electronic Protections
Fully protected against reverse polarity, short circuit, overcurrent, high temperature and
Simple Mechanical Interface
Larger power terminals and conduit knockouts. Extra space for wire turns. Fits on power
Better Battery Charging Connecting battery sense wires and optional remote temperature sensor will improve
control accuracy. Constant voltage series PWM algorithm increases battery capacity and life.
3 LEDs to indicate status, faults and alarms. Optional meter displays extensive system and
controller information, automatic self-test and reset capabilities. Meter
connection via RJ-11 phone jack.
Easy to Reset
Pushbutton provides manual reset and stop/start battery equalization or load disconnect.
Low Telecom Noise
DIP switch setting will change PWM to “On-Off” battery charging.
Morningstar TriStar MPPT charge controllers use TrakStar
technology for efficient and reliable solar battery charging. They can
provide up to 60 amps on an up to 150 volt open circuit input. The TriStar MPPT solar
charge controller with TrakStar technology is an advanced maximum power point tracking
(MPPT) solar battery charger for off-grid solar systems up to 3kW.
Morningstar TrakStar MPPT Technology
TrakStar is a smart tracking algorithm used by the TriStar MPPT to maximize the energy
harvest from the PV by rapidly finding the solar array peak power point with extremely
fast sweeping of the entire I-V curve. The Morningstar TriStar MPPT solar charge
controller provides the industry’s highest peak efficiency of 99% and
significantly less power loss compared to other MPPT controllers.
The TriStar MPPT is the first PV controller to include on-board
Ethernet for a fully web-enabled interface and includes up to 200 days of data logging.
