    Morningstar ProStar MPPT™ Solar Charge Controller

      The purpose of a solar charger is to collect energy from the solar panels and store it in the batteries. The Prostar MPPT solar charge controller is an advanced maximum power point tracking (MPPT) battery charger for off-grid photovoltaic (PV) systems up to 1100 watts. All versions include load control and TrakStar™ Technology to maximize PV efficiency and energy harvest.

      The ProStar design has been proven in over two decades of use in the world’s most demanding installations—and ProStar today reflects Morningstar’s policy of continuous improvement through regular upgrades and enhancements. Because Morningstar’s employee-owned culture never “rests on success,” ProStar customers can own both a legend and the latest in a single product.

      The Morningstar Prostar MPPT charge controller is available in four models:

      PS-MPPT-25:  25 Amp 

      PS-MPPT-25M:  25 Amp with built-in meter 

      PS-MPPT-40:  40 Amp 

      PS-MPPT-40M:  40 Amp with built-in meter 

      Why You Need an MPPT Charge Controller for Your Solar System

      There are two types of solar charge controllers on the market: MPPT (maximum power point tracking) and PWM (pulse-width modulation). The type of charge controller you need depends on the prevailing solar conditions you expect to encounter. MPPT controllers convert more energy into useable electricity and are best suited for areas where seasonal, weather, and shading conditions can cause significant variations in solar harvesting. MPPT controllers are ideal for mobile or off-grid solar applications such as on a campervan, RV, remote cabin, or tiny houses. 

      PWM controllers are less efficient than MPPTs and are best suited for large stationary systems with consistent sunlight, minimal shading, and no physical space limitations. PWM controllers are not generally a great fit for campervans or RVs. So for your van conversion we recommend an MPPT charge controller.

      All Morningstar charge controllers are built to industry-leading quality standards with over-spec’d components, advanced electronic design and thermal engineering, and have no cooling fans to fail. Over four million Morningstar controllers have been sold since 1993 and making them the first choice for leading solar installers around the globe.

      Key Features and Benefits

      High Reliability – conformally coated circuit board, corrosion resistant terminals, premium high-frequency CoilCraft inductors, over-spec’d components, transient surge suppression, and lowest published failure rate in the industry.

      Automatic PV Based Lighting Control – field adjustable, multi-event load control enables powerful options for PV lighting systems.

      Maximizes Energy Harvest – the TrakStar MPPT technology allows the user to determine and adjust to the true maximum power point as solar insolation changes throughout the day.

      MODBUS Communications – Solar Industry Standard MODBUS communications protocol allows for easy programming, control, remote data access and charge synchronization.

      SNMP Monitoring – when used with the EMC-1 accessory to enable your network management systems to display key solar power metrics and alert/fault codes.

      High Efficiency – at low, medium, and high output power levels to maximize energy harvest and minimize heat buildup inside the controller.

      High Strength – polycarbonate case and extruded aluminum heatsink.

      Data Logging – up to 256 days of detailed power and load data.

      Self Diagnostics – continuous monitoring and reporting of any errors through its status LED’s, optional display or communication port.

      Low Noise Design – meets US Federal Communications Commission Class B specifications.

      Meter – allows adjustments to charging, lighting, and load control settings without a computer.

      Fanless design promotes long-term reliability because there are no moving parts to fail. Additionally, the no-fan design eliminates parasitic load to enhance efficiency and reduces the amount of dirt and debris getting into the controller.
