Power to Test Commercial String Inverters

The PV simulators are autoranging, programmable DC power sources that simulate the output characteristics of a photovoltaic array under different environmental conditions (temperature, irradiance, age, cell technology, etc.) enabling you to quickly and comprehensively test inverter MPPT algorithms and inverter efficiency. The DG8900 SAS control software creates and downloads solar I-V curves to a single output solution. For multiple outputs choose the DG9000 SAS control software which can be used with up to 12 N8900APV sources.

  • Parallel supplies for up to 150 kW of power
  • Test multiple input inverter
  • Create Sandia, EN50530, and proprietary curves
  • View I-V curves, maximum power point
  • Static and dynamic EN50530 MPPT test
  • Automate EN50530 tests with formatting reports
  • LAN (LXI Core), USB, GPIB, and analog interfaces
  • Use existing power distribution with 208 and 400 VAC input

Test String Inverter's MPPT Algorithms

Keysight's PV simulation solution has the flexibility to test most string inverters. Keysight DG9000 advance / multi-input PV inverter test software can simulate up to 12 strings. The simulation uses popular curves or table mode allowing precise I-V curve with 1024 points. Go beyond test standards to maximize MPPT performance.
