ProStar PWM Charge Controller
12/24V, 30A with Display
PS-30M
Morningstar’s ProStar is the world’s leading mid-range solar controller for both professional and consumer applications. This second generation ProStar adds new features and protections using highly advanced technology. These improvements provide longer battery life and improved system performance. The ProStar line of controllers set new standards for reliability and self-diagnostics.
The new ProStar is available in 15 or 30 amps, 12/24 or 48 volt, and negative or positive ground. The controller may be paralleled for a solar input rating of up to 300 amps. An optional meter provides an extensive display of self-testing and system status.

- 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
- 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.
- 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".
The ProStar has 4 stages of charging to provide increased battery capacity and life.
- Recharging with 100% of available solar energy.
- PWM constant-voltage regulation to prevent heating and excessive battery gassing. Pulse charging to restore full battery capacity.
- Float: After battery is fully recharged, ProStar reduces to a float or trickle charge. The transition depends on battery history. A load that exceeds available solar output will return ProStar to the PWM mode.
- Equalize: A boost charge that depends on elapsed time and battery history. Flooded cells receive a vigorous equalization, sealed batteries a smaller boost to bring uneven cells into balance and extend the battery life. Gel cells are not equalized.
The Battery Type rotary switch allows selection of 1 of 3 charging algorithms. These are broadly defined as the following battery types as noted on the lower label:
- Gel: Some gel and other battery types recommend lower regulation voltages and no equalization. This setting regulates to 14.0V (for a 12V battery).
- Sealed: AGM, "maintenance free" and some types of gel batteries. Regulates to 14.15V (12V battery) with 14.35V boost charging.
- Flooded: Vented cells that require water to be added. Regulates to 14.4V with 14.9V and 15.1V equalizations (12V battery).
| Gel | Sealed | Flooded | |
|---|---|---|---|
| Regulation Voltage | 14.0 | 14.15 | 14.4 |
| Float | 13.7 | 13.7 | 13.7 |
| Equalization | n/a | 14.35 | 14.9/15.1 |
| Load Disconnect | 11.4 | 11.4 | 11.4 |
| Load Reconnect | 12.6 | 12.6 | 12.6 |
| Note: values are for 12V. Use 2X for 24V and 4X for 48V. | |||
