- Thank you,
"I recently found EcoDirect & have been extremely happy with their service. They have had all the PV modules, inverters, optimizers and accessories I needed. They provide excellent customer service & turn orders around very quickly. I have switched to EcoDirect for all my parts & materials orders. Highly recommended."

- Zeno
"I wanted to let you know I am very pleased with the service you gave & the quality & condition of the solar panels I received from EcoDirect. I will purchase more items in the future from EcoDirect and will be sure to tell others about your fine operation."

"Thanks EcoDirect! My solar system is up and running; waiting for City and San Diego Gas & Electric inspections this week; so far so good!"

"I enjoyed ordering what I needed. It was simple and fast, no issues what so ever. If I need something else and its at a good price, I will defiantly order from here again. Also the shipping is at a good price."

- Simon
My shipment arrived on time, as predicted. Very, very good performance by EcoDirect. What more could you ask for from an online material supplier? Looks like the quantity from Quick Mount is spot on & the rails were bundled safely. EcoDirect will be my recommended source to my friends & neighbors for solar.
- Thank you, Jim Lake

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



  • Versions available: 15 or 30 amp 12 / 24 or 48 volt negative or positive ground
  • Estimated 15 year life
  • PWM series battery charging (not shunt)
  • 3-position battery select: gel, sealed or flooded
  • Very accurate control and measurement
  • Jumper to eliminate telecom noise
  • Parallel for up to 300 amps
  • Temperature compensation
  • Tropicalization: conformal coating, stainless steel fasteners & anodized aluminum heat sink
  • No switching or measurement in the grounded leg
  • 100% solid state
  • Very low voltage drops
  • Current compensated low voltage disconnect (LVD)
  • LEDs indicate system status and various faults
  • Capable of 25% overloads
  • Remote battery voltage sense terminals

Detailed Description


  • 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".
