NOV-IV2000B Bifacial I-V Curve Tracer (2000 V / 40 A)
Field I-V curve tracer for modules and strings up to 2000 V / 40 A, with true bifacial front/rear measurement, ±3% STC accuracy and built-in PR monitoring. IP67 rugged case, 20-hour battery.
The NOV-IV2000B is built for today’s high-power PV plants. Its 2000 V / 40 A range covers 1500 V strings and high-current half-cut, TOPCon, HJT and bifacial modules, which most 1000 V / 20 A testers can no longer handle. Synchronised front and rear irradiance sensors separate front-side and rear-side generation without covering the back of the module. A built-in PR monitoring mode extends its use from commissioning and acceptance into long-term O&M diagnostics.
Key features
1 2000 V / 40 A range: tests 1500 V strings and high-current half-cut, TOPCon and HJT modules
2 True bifacial testing: synchronised front and rear sensors separate front-side and rear-side generation
3 ±3% STC accuracy: built-in database of 50,000+ module models
4 PR monitoring: automatic repeat tests with cumulative energy and PR curves
5 Commissioning pass/fail: instant OK / NOK verdict against the module datasheet
6 Built for the field: IP67 case, 20-hour battery, wireless sensors up to 100 m
