The SmartTS-PV Inverter Test System is a complete automated platform for testing PV inverters, energy storage systems (ESS), and distributed energy resources (DERs) to IEEE 1547.1, UL 1741 SB and European EN50549 grid interconnection standards.
The SmartTS-PV is is the first of it’s kind integrated 1547.1 test system. Designed for inverter manufacturers, certification labs, utilities, and R&D teams, the SmartTS-PV integrates grid simulation, DC power, precision measurement, and compliance automation into a single platform.
SmartTS-PV combines all required test elements into a synchronized, high-performance platform:
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.
The anti-islanding test requirements for Distributed Energy Resources such as PV inverters or bidirectional V2G EV Chargers are mandatory for regulatory approval of these energy producing devices. Option P mode is the built-in anti-islanding test operating mode for Pacific Power Source AZX and GSZ grid simulators.
When enabled, it configures the system to electronically emulate the resonant RLC load required for anti-islanding testing, execute the grid disconnection event, and precisely measure the inverter’s response time using an internal digital storage oscilloscope. This mode allows the grid simulator to function as a complete anti-islanding test system—combining grid simulation, load emulation, and disconnect-time measurement in one platform—without external components, multiple instruments, or custom test software.
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.
