NANJING, CHINA — June 13, 2026 — As global solar infrastructure rapidly scales up and transitions to higher voltage architectures, traditional field testing equipment is facing unprecedented operational limitations. Addressing the urgent industry demand for higher capacity, safer, and more intelligent diagnostic tools, Nanjing Vaeyi Technology Co., Ltd. (VAEYI) today officially announced the global launch of its flagship product: the IV2000 Portable Photovoltaic (PV) String Tester.
Engineered specifically for utility-scale commissioning, routine operation and maintenance (O&M), and rapid fault localization, the IV2000 stands out with a direct DC voltage testing capability of up to 2000V, which can be further expanded to 2200V. This breakthrough allows engineering, procurement, and construction (EPC) contractors and asset management teams to seamlessly service modern, high-output bifacial modules and next-generation high-voltage inverter systems that standard 1000V or 1500V testers cannot accommodate.
The IV2000 is built as an all-in-one diagnostic workstation housed in a rugged, highly portable enclosure weighing approximately 8.5 kg. Utilizing a precise 4-wire Kelvin sensing method, it consolidates multiple test parameters into a single operation, capable of measuring voltage (0–2000V), current (0–40A), and a nominal maximum power (Pmax) range of 10 to 50,000W.
To ensure precise performance benchmarking under unpredictable outdoor conditions, the instrument features automated Standard Test Conditions (STC) correction. This technology instantly translates real-time field data into standard laboratory equivalents, allowing technicians to execute highly accurate low-irradiance PV characteristics tests with confidence.
Unlike conventional testing meters, the IV2000 operates on a robust Linux-based platform. This architecture ensures exceptional system stability, continuous automated data logging directly to high-capacity storage, and an expansive suite of networking capabilities designed to streamline asset management workflows.
Key digital and wireless integrations include:
Long-Range Wireless Control: High-power Class 1 Bluetooth communication allows operators to control the unit safely from up to 50 meters away.
Built-in 4G LTE Module: Enables remote smartphone operations, cloud synchronization, and real-time remote monitoring.
High-Speed Hardware Interfaces: Equipped with a Gigabit Ethernet port for instant data transfer alongside standard Type-A, Type-C, RS485, and RS232 interfaces.
On-board Database: Features an integrated, extensive manufacturer database covering mainstream global PV modules for rapid asset identification during field testing.
Operating in high-voltage environments requires uncompromised operator protection. The IV2000 incorporates comprehensive multi-tier hardware and software safety guards, including over-voltage, over-current, and over-temperature protection. Powered by an internal 12.6V, 6400mAh rechargeable lithium battery pack, it ensures extended operational uptime during prolonged field deployments.
The IV2000 is shipped as a fully complete field kit to ensure immediate operational readiness upon arrival. The standard package includes the main instrument, a specialized test lead set with alligator clips, heavy-duty MC4 adapter cables, and the standalone Solar100 Pyranometer (Irradiance Meter) complete with its dedicated mounting bracket and charging system. Optional high-capacity 10,200mAh backup batteries and specialized PT1000 temperature measurement probes are also available to meet customized regional testing requirements.
