PVCHECKs-ONE: The All-in-One Frontline Testing Solution
The PVCHECKs-ONE is a comprehensive, all-in-one meter designed to support the commissioning, verification, and troubleshooting of photovoltaic (PV) installations. Combining high-performance measurement capabilities with advanced diagnostic functions, it enables technicians to quickly assess system integrity, identify issues, and ensure reliable operation.
Thanks to its cutting-edge technology, technicians can easily perform commissioning tests in full compliance with IEC/EN62446-1 Category 1 requirements, while efficiently identifying ground faults during troubleshooting. With its fully automated test sequences, PVCHECKs-ONE ensures comprehensive certification of the performance and safety of both Monofacial and Bifacial PV modules. The instrument also introduces two innovative features that further enhance testing experience and operational efficiency:
- AUTOSTART/AUTOSAVE function
- Insulation testing on PV strings with DC optimizers
AUTOSTART & AUTOSAVE FUNCTION
The automatic sequential testing is engineered to maximize the throughput by reducing the time needed to test each PV string. PVCHECKs-ONE connects directly to the bus bars inside the combiner box, allowing seamless operation. Starting with all string fuses or switches open, the technician simply enables one string at a time. As soon as PVCHECKs-ONE detects voltage at its inputs, it automatically initiates the test sequence—performing the five measurements required by IEC/EN62446-1 and storing all results in its internal memory. When the fuses or switches of the tested string are reopened and those of the next string are closed, PVCHECKs-ONE immediately begins the next test cycle. No manual action is required; the instrument handles the entire process autonomously for fast, reliable, and efficient testing.
