Photovoltaic Power Generation Test Solution

Photovoltaic Power Generation Test Solution

With years-long expertise in new-energy testing & measurement, Hopetech develops an integrated matrix of safety and reliability test instruments for full-process inspection of PV modules. we deliver stable, high-precision instruments for PV module manufacturers and laboratories. Our solutions cover critical links: factory safety inspection, high-voltage insulation verification, earthing reliability and contact-resistance monitoring of test fixtures.

HT9914 Comprehensive Safety Tester — Production–Line Chief Inspector

All-in-one 7-inch touch-screen instrument. It completes AC/DC hipot, insulation resistance, earth resistance and bypass-diode tests in one run. It conducts full safety screening for PV modules per IEC standards and rejects defective units, serving as the critical first-gate quality control before shipment.

CHT9951A/B High–voltage Hipot Tester — High–Limit Safety Inspector

Max. DC 15 kV output, insulation resistance up to 99 GΩ, with 9-level arc detection. Designed for high-voltage hipot and insulation-breakdown verification of PV modules. It identifies hidden insulation defects under high-voltage stress and ensures safe long-term outdoor operation.

CHT9931A Earth Continuity Tester — Lightning–Protection Safety Guardian

DC output: 10-100 A; resistance measuring range: 0.01 μΩ-600 mΩ for accurate low-resistance loop measurement. It tests earthing resistance of PV frames and mounting brackets, verifies lightning-protection performance and mitigates lightning-related safety risks.

HT1035–IV 4–Wire Reliability Monitoring System — IV–Fixture Supervisor

Real-time monitoring of contact resistance for IV-test connectors. Auto-alarm triggers once resistance exceeds thresholds. It detects fixture ageing and poor contact in advance, avoiding measurement drift and distorted PV power-test results.

This PV test solution covers four core scenarios: pre-shipment safety compliance, high-voltage insulation validation, earthing-safety verification and IV-fixture reliability monitoring. Instruments work together to handle both routine quality control and extreme-condition validation, covering finished-product inspection as well as fixture-condition surveillance. It helps PV manufacturers comply with IEC international standards, reduce outdoor safety hazards of PV modules, minimise test-data errors and improve production-line inspection stability.
