Gossen-Metrawatt Photovoltaic Tester, 1500V Maximum Voltage Measurement, 0.5A Minimum Current Measurement - 601A910

This photovoltaic tester is a portable diagnostic instrument designed for assessing solar arrays and PV installations under normal field conditions. It measures high-voltage DC supplies and low-level currents to support commissioning and routine checks, operating within typical ambient temperatures used on-site.

Features and Benefits:

• ±0.5% voltage accuracy ensures precise DC measurement
• 0.5A short-circuit current sensitivity detects low fault currents
• 25A clamp capability enables non-invasive operating current checks
• Lithium-ion battery delivers portable operation for fieldwork
• IEC 62446 conformity supports standard-based measurement workflows

Applications

• Suitable for on-site solar array commissioning and acceptance tests
• Ideal for maintenance checks on rooftop PV systems
• Used with string-level diagnostics for fault localisation
• Can be used for clamp-based operating current surveys
• Suitable for installers working in varied ambient temperatures

What temperature range is appropriate for use?

It is intended to be operated between 5°C and 40°C.

What voltage span can it measure on PV systems?

The instrument measures DC up to 1500V.

How accurate is the current measurement with the clamp?

The clamp measures operating current with ±5%+2 digits accuracy.

Which standard does it align with for PV testing?

It meets requirements of IEC 62446.

What are the unit’s physical dimensions?

The overall size is 265mm length, 115mm width, and 78mm height.
