Morningstar Corporation
ProStar PWM Charge Controller
12/24V, 15A With Display

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.


  • PWM series battery charging (not shunt)
  • 3-position battery select: gel, sealed or flooded
  • Very accurate control and measurement
  • Jumper to eliminate telecom noise
  • Tropicalization: conformal coating, stainless steel fasteners & anodized aluminum heat sink
  • Current compensated low voltage disconnect (LVD)
  • LED’s indicate battery status and faults
  • Capable of 25% overloads
  • 5 Year Warranty

Electronic Protections

  • 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

  1. The ProStar uses stainless steel fasteners, an anodized heat sink, and conformal coating to protect from harsh conditions. However, for acceptable service life extreme temperatures and marine environments should be avoided.
  2. The ProStar prevents reverse current leakage at night, so a blocking diode is not required in the system.
  3. The ProStar is designed to regulate ONLY solar (photovoltaic) power. Do not connect it to any other type of power generator. Do not attempt to regulate a wind turbine. However, other power sources can be connected directly to the battery.
  4. The connector terminals will accept a maximum wire size of AWG #6 /16 mm2 (solid/multistrand) or AWG #8 / 10 mm2 (fine strand). Use a flathead insulated screwdriver, and torque tightly up to 35 in-lb.
  5. Fuses or DC disconnects may be required in the system. These protection devices are not part of the ProStar controller.
  6. The Solar, Battery, and Load negative terminals are all connected together inside the ProStar per UL recommendations. No switching or measurement is done in the negative current path.
  7. For positive ground versions, the Solar, Battery and Load POSITIVE terminals are connected together inside the ProStar. The positive system conductor must be properly grounded. Make sure the upper label of the ProStar indicates "Positive Ground" above the version number to confirm this is a positive ground ProStar controller.
Warranty: Five year warranty period. Contact Morningstar for complete terms.
