The solar energy industry has been developing for many years, and the technology of photovoltaic inverters has become increasingly mature. Correspondingly, various regulations have become more stringent in their requirements for photovoltaic inverters. However, different regulations are given varying degrees of importance around the world, and their scope of application also differs. When a new product is launched, it is essential to consider the environment of the sales region and fully comply with the regulatory requirements emphasized in that region in order to truly gain a broad market share.
1. Meet the newly added standard test items for photovoltaic inverters.
Standard test items, such as conversion efficiency measurement, maximum power point tracking efficiency measurement, and output overvoltage protection, are included in various important regulations, such as EN50530, UL1741, CGC/GF004, JETGR0002, GB/T19939, IEEE1547 & IEEE1547.1. These are highly regarded standards in various regions of the world, making these test items a basic requirement for the factory testing of photovoltaic inverters. Therefore, it is essential to include them in the standard test items of the testing instrument system for direct use by users. Otherwise, customers will not be able to conduct testing and certification according to the requirements of the new standards, or they will have to replace the old ones and purchase new testing instruments to meet the requirements.
2. Generate more accurate I–V curves
There are two major regulations, Sandia and EN50530, that make clear requirements for the input conditions of photovoltaic inverters. The two regulations have different definitions for the IV curve at the inverter input. This requires the inverter automatic test system to simulate IV curves with various characteristics through the integration of software, firmware and hardware, so as to create input conditions that fully comply with the regulations. In this way, the data of all test items will be more convincing.
The Chroma8000 automatic test system is a general-purpose automatic test system developed by Chroma Electronics. It can be applied to the testing of various power supply products. In recent years, with the development of the green energy industry, special automatic test systems such as 8491/8000PV/8000EV have been developed for various green energy applications. Among them, 8000PV is specifically designed for the testing of photovoltaic inverters.
