Gossen-Metrawatt Photovoltaic Tester, 1500V Maximum Voltage Measurement, 25A Maximum Current - 601A916

This photovoltaic tester is a portable instrument designed to assess and verify solar array performance in field and workshop settings. It measures DC voltage and current across PV installations and evaluates short-circuit and operating currents under typical site conditions. The unit operates within common ambient ranges and is powered by an internal rechargeable lithium‑ion cell to support repeated on‑site diagnostics.

Features and Benefits:

• ±0.5% voltage accuracy for positive DC ensuring precise module readings
• ±1% ISC accuracy for short-circuit current enabling accurate fault detection
• 1500V maximum voltage measurement supporting high-voltage arrays
• 25A maximum current capacity for robust string-level testing
• Clamp-based operating current measurement with ±5% accuracy for live checks

Applications

• Suitable for commissioning large roof-top and ground-mounted arrays
• Ideal for diagnosing short-circuit faults in solar strings
• Used with clamp sensors for live operating current measurements
• Can be used for maintenance checks across distributed PV systems

What battery type does it use and how does that affect field use?

It uses a lithium‑ion battery which provides a rechargeable power source suitable for repeated on‑site testing sessions.

What ambient conditions can it be operated in?

It is designed to function within an ambient temperature range of 5 to 40°C to match typical installation environments.

How small a voltage can it detect for module-level checks?

It can measure down to a minimum voltage of 10V DC for low-voltage module assessments.

What accuracy applies when measuring negative DC or AC voltages?

Voltage accuracy for negative DC and AC is ±5% Plus 2 digits, reflecting measurement tolerance in those modes.
