Automate Grid Integration and Compliance Testing
Accelerate grid integration and compliance testing with an expandable suite of automated software for distributed energy resources. Built on PathWave Test Automation and Keysight regenerative AC/grid emulators, the suite coordinates stimulus, measurements, communications, analysis, and reporting for repeatable IEEE 1547.1-2020 and UL 1741 SB workflows.
The Keysight Grid Integration Test Suite helps experienced compliance teams and engineers new to grid testing reduce the complexity, time, equipment, and lab space required to validate distributed energy resources. Automate IEEE 1547.1-2020 electrical type tests for voltage and frequency disturbances, including trip, ride-through, rate-of-change-of-frequency, and phase-angle-change procedures. Extend coverage with PHIL-based anti-islanding automation, SunSpec Modbus communications, and automated DER configuration and readback. Use predefined applications for repeatable workflows or create custom AC/grid test sequences as requirements evolve.
Automated Compliance Testing
Accelerate IEEE 1547.1-2020 and UL 1741 SB workflows with coordinated grid stimulus, measurements, analysis, and reporting. Automate voltage and frequency disturbance tests and PHIL-based anti-islanding procedures for repeatable results.
Expandable Test Coverage
Select the software capabilities needed today and expand as requirements evolve. Combine custom AC/grid sequencing, electrical type tests, anti-islanding automation, and interoperability tools in one test environment.
Integrated DER Communications
Use SunSpec Modbus to read DER identification, status, measurements, and settings. Automate communications setup, configuration, readback, and verification within disturbance test workflows to reduce manual reconfiguration.
Scalable Grid Emulation
Pair the suite with SL1200A Series regenerative AC/grid emulators for 1-, 2-, or 3-phase testing. Scale systems by paralleling units to support higher-power distributed energy resources up to 1.35 MW / 2.0 MVA.

SL1221A
SL1221A automated anti-islanding test per IEEE 1547.1-2020 & UL1741SB. Anti-Islanding compliance test automation for energy innovators, boosting productivity and reliability.
PHIL-Based Automated Anti-Islanding Test Solution
As distributed energy resources (DERs) proliferate, ensuring grid stability and safety becomes increasingly critical. Validating the inverter's anti-islanding features and algorithms is vital to ensuring safe operation and compliance with grid codes.
Anti-islanding testing has traditionally been a time-consuming, equipment-intensive process, including manual tuning of a load bank containing resistors, inductors, and capacitors (RLC). The Keysight SL1221A automates anti-islanding testing using real-time simulation and power hardware integration. This approach reduces manual effort, improves repeatability, and accelerates time to certification.
- Automated anti-islanding testing aligned with IEEE 1547.1-2020 / UL 1741 SB standards
- Patent-pending resonant RLC autotuning eliminates manual tuning and reduces test time
- PHIL-based real-time simulation ensures reliable and fast testing
- Compact, integrated test setup reduces lab space and energy consumption
- Seamless software integration with KS8400B PathWave Test Automation for streamlined workflows and reporting
