In addition, the inverter must also be verified for functionality typically consisting of the following:
Sourcing solar panels to provide the DC input for testing is not cost-effective. The best practice calls for simulation of the energy which allows for complete control to truly stress the DUT. Connecting an untested product to a live utility grid is also not advised. The preferred method is to recoup the energy in a simulated and controlled environment that allow for the duplication of real-world effects. This is accomplished with an AC Grid Simulator. Surrounding the DUT with these types of products reduces time to market in addition to the obvious reduction in operational costs.

The Better Way
Thankfully, Intepro offers our PSI Series of high-efficiency (up to 95%) DC Power Supplies and our Regenerative AC Source/Grid Simulator to surround PV inverters with energy-saving technology (depicted in Figure 1). In addition, the PSI Series boasts a powerful “PV Sim” Suite designed to fully simulate a variety of PV Systems, IR curves, and accurately track MPP (Maximum PowerPoint). This gives you the tools you need to work on your product right out of the box.
If you would like to learn more or are interested in a demonstration showing how we can help you get the most out of your PV Inverter testing, please feel free to reach out to us.
