ProStar Gen 3 vs. ProStar MPPT Review

ProStar Gen 3 PWM charge controllers

ProStar Gen 3 Solar Charge Controllers

ProStar Gen 3 PWM charge controllers offer additional features and capabilities over previous generations. Morninstar has maintained the same form factor, quality, and reliability that has made the ProStar the world’s leading mid-range PWM solar controller for professional and consumer applications since 1995.

Designed for the the harshest environments, the ProStar has developed a strong reputation for reliable performance. The ProStar Gen 3 offers data, lighting control, graphical interface, and protection features to better meet the needs of off-grid solar systems. ProStar Gen 3 PWM charge controllers will accommodate sealed, gel and wet-cell lead-acid batteries.

  • High reliability – latest electronic and environmental protections, quality control, and design considerations comply with IEC 62109 and promote longevity in the harshest environments.
  • High Temperature Design – full nameplate current rating, both solar and load up to 60°C continuous.
  • Auto-battery Select – 12V and 24V systems.
  • 4-stage Battery Charging - Bulk, Absorption, Float, Equalize
  • Data Logging – up to 256 days of solar charge and load consumption data.
  • Low Noise Design – meets US Federal Communications Commission Class B specifications.
  • Automatic Solar Based Lighting Control – field adjustable, multi-event load control enables powerful options for solar lighting systems.
  • MODBUS Communications – open standard MODBUS communications protocol allows for control and remote data access.
  • Durable Design – high strength polycarbonate case with protective terminal cover and extruded aluminum heatsink.
  • Self Diagnostics – continuous monitoring and reporting of any errors or system faults through its status LED’s, optional display and communication port.
  • Meter (M Model) – high resolution LCD, multi-lingual backlit graphical display of system voltage, current, temperature, lighting settings, etc.
  • Custom Programming – dip switches, meter interface, or connection with a computer can be used to adjust charging, load, communications, and lighting control.
ProStar Gen 3 without meter

The ProStar Gen 3 PS-15 and PS-30 models without meter are also available for our systems.

ProStar MPPT charge controllers

ProStar MPPT Solar Charge Controllers

ProStar MPPT™ solar charge controller with TrakStar Technology™ is an advanced maximum power point tracking (MPPT) battery charger for off-grid photovoltaic (PV) systems up to 1100 watts. This controller allows multiple modules in series for 12V and 24V battery systems.

TrakStar MPPT technology provides the ability to charge 12 or 24 volt batteries with solar arrays of higher nominal voltages. A 12 volt battery bank can be charged with a 12, 24, 36 or 48V nominal off-grid solar array. Detailed battery programming options allow for advanced battery support for the latest Lithium, Nickel Cadmium, and Lead Acid battery types.

TrakStar MPPT
  • High Reliability – conformally coated circuit board and corrosion resistant terminals.
  • Maximizes Energy Harvest – using TrakStar MPPT Technology to determine and adjust to the true maximum power point as solar insolation changes throughout the day.
  • High Efficiency – at low, medium, and high power levels.
  • Data Logging – up to 256 days of detailed power and load data.
  • Low Noise Design – meets US Federal Communications Commission Class B specifications.
  • ProStar MPPT 40 with Meter and wire box

  • Automatic PV Based Lighting Control – field adjustable, multi-event load control enables powerful options for PV lighting systems.
  • MODBUS Communications – Solar Industry Standard MODBUS communications protocol allows for easy programming, control, remote data access and charge synchronization.
  • High Strength – polycarbonate case and extruded aluminum heatsink.
  • Self Diagnostics – continuous monitoring and reporting of any errors through its status LED’s, optional display or communication port.
  • Quality Hardware - The ProStar MPPT uses stainless steel fasteners, an anodized aluminum heat sink, and conformal coating to protect it from harsh conditions.
