MORNINGSTAR TRISTAR SOLAR CONTROLLER
MORNINGSTAR TRISTAR SOLAR CONTROLLER
Morningstar’s TriStar Controller is a three-function controller that provides reliable solar battery charging, load control or diversion regulation. The controller operates in one of these modes at a time and two or more controllers may be used to provide multiple functions.
The TriStar uses advanced technology and automated production to provide exciting new features at a competitive cost. The controller is designed for both solar home systems and professional applications.
APPLICATIONS
- Charge Control
- Constant voltage series PWM design to provide highly efficient battery charging
- 4-stage charging to increase battery capacity and life: bulk charge, PWM regulation, float and equalize
- Parallel for larger solar arrays up to 300 amps or more
- Load Control
- Starts large loads including motors and pumps with no damage to controller
- Allows inrush current to 300 amps
- Electronic short-circuit and overload protection with automatic reconnect
- LVD is current compensated and has a delay to avoid false disconnects
- Diversion Control
- May be used for solar, wind or hydroelectric
- To protect against battery overcharge, excess energy is diverted from primary battery to a secondary battery or alternate DC resistive load
- PWM reduces power into diversion load during overcurrent conditions
FEATURES
- Large heat sink and conservative design enables operating at full ratings to 45°C. 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
- DIP switch provides user with a choice of 7 different digital presets and custom settings via RS-232
- Fully protected against reverse polarity, short circuit, overcurrent, high temperature and overvoltage
- Larger power terminals and conduit knockouts . Extra space for wire turns. Fits on power panels
- Connecting battery sense wires and optional remote temperature sensor improves control accuracy. Constant voltage series PWM algorithm increases battery capacity and life
- 3 LED’s 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
- Push button provides manual reset and stop/start battery equalization or load disconnect
- DIP switch setting will change PWM to “On-Off” battery charging
ELECTRONIC PROTECTIONS
- Reverse polarity protection (any combination)
- Short-circuit protection
- Overcurrent protection
- Lightning and transient surge protection using 4,500 W transient voltage suppressors
- High temperature protection via automatic current reduction or complete shut down
- Prevents reverse current from battery at night
