MorningStar ProStar 30 Amp 12/24 Volt PWM Charge Controller
Options: Digital Display
Manufacturer Part Number: PS-30M
The Morningstar ProStar 30 (PS-30M) is commonly used for small to medium off grid and other battery systems, such as backup power supplies. It can be used for any 12 or 24 volt battery system. It will handle up to 30 amps from the solar panels - about 500 watts of panel at 12 volts, 1000 watts at 24 volts. Morningstar's series switching provides many advantages compared to shunt controllers. Series regulation reduces FET heating and lowers voltage stress on the power FET's. A series configuration also improves protection against lightning surges and reduces switching noise. The series design improves charging accuracy. In PWM, series switching becomes self-correcting for temperature and system voltage drops. May be paralleled up to 300 amps.
Morningstar’s ProStar is the world’s leading
mid-range solar controller for both professional
and consumer applications. This third generation ProStar (PS-30M) provides the following:
- Adds new features and protections using highly advanced technology
- Provides longer battery life and improved system performance
- Sets new standards for reliability and self-diagnostics

Detailed Description
Electronic
- Short-circuit — solar and load
- Overload — solar and load
- Reverse polarity
- Reverse current at night
- High voltage disconnect
- High temperature disconnect
- Lightning and transient surge protection
- Loads protected from voltage spikes
- Automatic recovery with all protections
Charging
- Night Disconnect: The solar array automatically disconnects at night to prevent
reverse current leakage from the battery.
- Battery Sense: Good battery performance requires accurate charging. Voltage drops
in the battery power cables can distort the battery charging. The Sense wires
eliminate the voltage drops for optimized charging.
- Temperature Compensation: Four control setpoints (25°C reference) are
compensated for temperature (PWM regulation, float, equalization, high voltage
disconnect). The charging is compensated by –5 mV/°C /cell (–30mV/°C for a 12V
battery). Compensation is limited to minus 30°C.
- Remote Temperature Probe: An optional probe is available to measure temperature
at a location away from the controller. This requires soldering 2 wires to the ProStar
PCB.
Options
- Digital meter
A precision 3-digit digital meter will continuously display battery voltage, solar current, and the load current. The meter automatically scrolls through these 3 displays. The 3 red LEDs will indicate which parameter is being displayed.
The digital meter will operate from –30°C to +85°C. The values displayed are calibrated
electronically in production and are accurate to within a few percent. Please note, however,
that if the Battery Sense is not connected, the voltage displayed will be in error by the voltage drops in the battery wires.
- Highly accurate voltage and current display
- Low self-consumption (1 mA)
- Includes manual disconnect button
- Displays 5 different protection functions
and disconnect conditions
- Self-diagnostics (self-test) provides a
comprehensive test of the ProStar —
- Displays 9 different controller status
parameters, including temperature
- Displays detected faults
- Positive ground
- Remote temperature probe
An optional remote temperature probe can be soldered to the ProStar assembly at
any time. The standard cable length is 25 ft (7.6 m), and this can easily be extended
to 100 ft (30 m) or longer. The 2 probe wires are soldered to the main board
assembly between the temperature sensor and the green LED, at "J12".
