As grid interconnection standards continue to evolve, PV inverter manufacturers face increasing pressure to validate complex grid-support behaviors under tightly controlled conditions. Requirements such as IEEE 1547, UL 1741 SB, and EN 50549 demand advanced functionality—voltage ride-through, frequency response, anti-islanding, and reactive power control—tested across a wide range of dynamic grid scenarios.

Traditional test setups—fragmented across multiple instruments and vendors—introduce integration challenges, limit repeatability, and extend certification timelines.

SmartTS is a fully integrated, turnkey inverter test system designed to eliminate these constraints—enabling faster validation, reduced risk, and complete certification readiness.

SmartTS-PV transforms inverter testing from a bottleneck into a strategic capability. Validate against certification requirements early in the development cycle—reducing downstream risk and rework.

The SmartTS PV Inverter Test System enables comprehensive validation of critical DER grid support functions required for UL 1741 SB and IEEE 1547.1 compliance. These functional tests—such as ride-through, frequency-watt, and volt-var—are executed and automated using QualityLogic’s 1547.1 test software, which manages test sequencing, timing, and data capture. Pacific Power Source grid simulators provide the precise voltage and frequency disturbances, along with source and load capabilities, needed to replicate real-world grid conditions.

Together, the software and grid simulator create a coordinated test environment that ensures accurate, repeatable validation of inverter performance against utility interconnection requirements.

Anti-islanding verification is a required step for certifying Distributed Energy Resources (DER), including PV inverters and bidirectional V2G EV chargers, to meet grid interconnection standards. Pacific Power Source’s Option P provides a dedicated anti-islanding test mode integrated into AZX and GSZ grid simulators.

With Option P activated, the system digitally replicates the resonant RLC load profile needed for testing, initiates the simulated grid loss condition, and captures inverter trip response time using a built-in digital oscilloscope.

This integrated approach enables the grid simulator to serve as a complete anti-islanding test solution—combining grid simulation, load emulation, and precise timing measurement in a single platform—eliminating the need for additional hardware, instrumentation, or custom-developed test scripts.

The SmartTS PV Inverter Test System combines fully integrated hardware with advanced automation software to deliver a true turnkey solution for UL 1741 SB and IEEE 1547.1 testing. Powered by QualityLogic’s 1547.1 test tools, the system uses a standard SCPI interface to automatically configure, control, and capture data from all supported equipment for each of the IEEE 1547.1 grid support tests—eliminating the need for custom scripting.

QualityLogic’s test software includes use of required interoperability protocols and automatic data analysis that evaluates your device’s power responses to the IEEE 1547 functions to assess its compliance to the performance requirements.

By standardizing and automating complex test sequences, SmartTS significantly reduces setup time, improves test consistency, and can accelerate certification timelines from months to weeks, helping manufacturers bring products to market faster.

Testing can now be completed in approximately 32 hours of actual test time versus IREC’s 8-12 week estimate for manual NRTL testing, significantly accelerating certification timelines.
