UNI-T UT219PV Details

Premium Solar Testing Capabilities

The UNI-T UT219PV's high voltage measurement range (up to AC 1500V, DC 2500V) sets a new standard for professional solar testing. This expanded range accommodates modern high-voltage solar arrays and battery storage systems, eliminating the need to switch meters when working on different system components.

Solar professionals will appreciate the built-in polarity indication system, which provides both visual and audible alerts when DC voltage below -10V is detected. The red LED flashes for 10 seconds, accompanied by buzzing, while the LCD screen displays a "POLARITY" symbol – providing immediate feedback on reversed probe connections during installation verification.

Precision Engineering for Field Reliability

The ultra-thin 35mm jaw design allows technicians to access conductors in tight spaces commonly found in solar installations. Whether measuring current in combiner boxes, inverters, or other confined areas, the UT219PV offers unmatched accessibility without compromising measurement quality.

With an IP65 protection rating, the UT219PV withstands both dust and water exposure – essential for solar field technicians working in unpredictable outdoor environments. This professional-grade construction ensures continuous reliable operation, reducing equipment failures and downtime during critical installation and maintenance tasks.

Advanced Measurement Functionality

The UNI-T UT219PV provides comprehensive measurement capabilities essential for solar professionals:

• AC/DC Current: Measure up to 999.9A with exceptional accuracy
• AC/DC Voltage: Range from millivolts to kilovolts (999.9mV to 2500V)
• Resistance: Multiple ranges from 999.9Ω to 99.99kΩ
• Capacitance: Measure up to 1000μF
• Frequency: Range from 5.0Hz to 999.9Hz
• Temperature: -40°C to 400°C (-40°F to 752°F)
• DC Power Calculation: Calculate system output up to 2500kVA

The true RMS functionality ensures accurate measurements regardless of waveform distortion, critical when evaluating inverter output quality and system performance.

Smart Connectivity for Data Management

The UNI-T UT219PV integrates seamlessly with modern workflows through Bluetooth 5.0 connectivity. The accompanying app allows technicians to:

• Record measurement data in real-time
• Generate comprehensive testing reports
