Morningstar ProStar PS-30M: High-Capacity Power Management with Real-Time Diagnostics

The Morningstar ProStar PS-30M is the definitive 30-amp PWM solar controller for professional off-grid systems. This "M" version features an integrated high-resolution digital display, providing instant access to battery voltage, solar current, load consumption, and system temperature. Capable of handling up to 500W at 12V or 1000W at 24V, the PS-30M is the perfect solution for mid-sized residential cabins, remote telecommunications hubs, and mission-critical industrial monitoring.

Built to endure the world's most demanding environments, the PS-30M is "Tropicalized" with conformal coating on all internal electronics and marine-rated terminals. It is globally certified for Hazardous Locations (Class 1 Division 2, ATEX, and IECEx), ensuring safe operation in oil and gas fields. With an estimated 15-year service life and a fanless design, it provides silent, high-performance regulation in temperatures up to 60°C.

Premium Performance & Monitoring:

• Graphical Digital Interface: The backlit, multi-lingual LCD displays real-time system data and allows for field adjustments of lighting and charging settings.
• 256-Day Data Vault: Internal memory logs daily solar performance and load usage. Review historical peaks and battery cycles directly on the screen to optimize your system.
• Industrial-Grade Hardening: 100% solid-state design with zero mechanical relays. Massive anodized aluminum heatsink allows for full 30A current at high ambient temperatures.
• Advanced Battery Care: 4-stage PWM charging (Bulk, Absorption, Float, and Equalize) with temperature compensation maximizes the life of Sealed, Gel, and Flooded batteries.
• Telecom Ready: Low-noise design meets FCC Class B specifications, ensuring zero interference with sensitive radio or satellite equipment.
• Hazardous Location Certified: Approved for Class 1, Division 2 and ATEX/IECEx Zone 2, making it the industry standard for industrial off-grid infrastructure.

Technical Specifications:

Technical Tip: For high-current 30A systems, wire size is critical to prevent voltage drop. The PS-30M accepts up to #6 AWG wire. We strongly recommend using the "Battery Sense" terminals to ensure the controller reads the exact battery voltage, providing the most accurate charging possible.
