High Power Density
The IT6600PV series, with its compact 3U chassis design, provides up to 42kW of power supply and loading capability in a limited space, significantly saving test space. This device supports high-performance, high-power test schemes and can be placed directly on the lab bench, making it particularly suitable for integrated system applications with space constraints.

Solar Cell Array Simulation I-V Curve Power Supply
The IT6600PV series is equipped with a SAS test interface specifically designed for solar photovoltaic curve simulation, supporting maximum power point tracking tests for photovoltaic arrays/modules/batteries. In User-defined mode, users can easily set parameters such as Voc (open-circuit voltage), Vmp (maximum power point voltage), Imp (maximum power point current), and Isc (short-circuit current) to generate specific I-V curve outputs. Curve mode provides photovoltaic simulation functions based on EN50530 and Sandia standards, allowing users to select the appropriate solar panel materials according to different standards and perform simulations by setting the Vmp (maximum power point voltage) and Pmp (maximum power point power) parameters, which is very suitable for verifying the performance of photovoltaic inverters (PV Inverter).

Completely Independent Dual Channels
The IT6600PV series achieves a dual-channel 21kW output within a 3U chassis. Each channel is a completely independent and isolated design that can be controlled and measured independently. The two channels can also be connected in series and parallel, expanding the power to 42kW within a 3U volume, increasing the output range of the IT6600PV series to meet complex and changing testing needs.

Standard Multi-channel Solar Matrix Simulation Software
          For more complex photovoltaic testing needs, users can use the standard multi-channel solar matrix simulation software of the IT6600PV series to easily output, measure, and display the maximum power point tracking (MPPT) status and numerical records of the photovoltaic inverter in real time. The software includes five mainstream regulatory testing procedures such as EN50530/Sandia, allowing users to conveniently test the static and dynamic MPPT performance of photovoltaic inverters and generate detailed reports for easy comparison with competitors.
           In addition, the software also provides shadow, Table and List modes, allowing users to input a 128~4096-point matrix to edit any shielded I-V curve to achieve a dynamic cloud cover effect, and can also store 100 I-V curves under different illumination and temperature conditions to test the long-term maximum power point tracking performance of photovoltaic inverters under different climatic conditions. These functions provide strong technical support for photovoltaic equipment manufacturers in improving product performance and reducing costs.
