VOLTCRAFT VC925 PV Solar Digital Multimeter True RMS 20000 Counts IP65 CAT III 1500V CAT IV 1000V Bluetooth VC-15361740

Solar installations demand precise, safe measurement tools that can handle high DC voltages up to 1500 V and harsh outdoor conditions. The VOLTCRAFT VC925 PV is a professional digital multimeter built specifically for photovoltaic systems, combining True RMS accuracy, a rugged IP65-rated housing, and CAT III 1500 V / CAT IV 1000 V safety ratings. Its 20,000-count display and Bluetooth connectivity make it an indispensable instrument for solar technicians and electrical engineers who need reliable data logging and analysis in the field.

Who is it for

This multimeter is tailored for solar PV installers, maintenance crews, and electrical contractors working on residential, commercial, or utility-scale solar arrays. It is equally suited for industrial electricians who require high-voltage CAT ratings and environmental protection. Whether you are commissioning new panels, troubleshooting string faults, or performing routine inspections, the VC925 PV delivers the precision and durability needed for demanding jobs.

Main features

Tips

For maximum safety when measuring high-voltage PV strings, always connect the test leads before powering the circuit and use the correct CAT-rated probes. The Bluetooth function pairs with the VOLTCRAFT app (available for iOS and Android) to log measurements over time, which is invaluable for detecting intermittent faults. When measuring temperature, ensure the K-type probe is properly connected and select the correct range. Replace all six AA batteries when the low-battery indicator appears to maintain accuracy.
