Key Features & Benefits

  • 1800W High-Capacity Testing — Engineered to handle larger panels and high-output arrays, providing accurate Maximum Power Point (Pmax) readings.

  • Extended 120V Range — Specifically designed for higher voltage systems, allowing for safe and accurate testing of a wider variety of professional-grade solar panels.

  • Instant Performance Diagnostics — View Open Circuit Voltage (Voc), Short Circuit Current (Isc), real-time wattage, and amperage on one ultra-clear LCD display.

  • Self-Powered Convenience — No batteries or external charging required; the unit draws power directly from the solar panel under test for immediate field use.

  • Expert Troubleshooting — Quickly identify underperforming panels or manufacturing defects by comparing live data against the panel's rated specifications.

  • Universal Connectivity — Equipped with heavy-duty MC-4 connectors and alligator clips to ensure a secure, plug-and-play connection to any panel type.

  • Rugged Field Design — Features a distinct green and white housing and includes a protective EVA toolkit for safe transport to remote off-grid sites.
