The solar energy industry has been developing for many years, and the technology of photovoltaic inverters has also matured. In contrast, the requirements of major laws and regulations for photovoltaic inverters are also more stringent. However, the importance of different regulations in different parts of the world varies, and the scope of application of various laws and regulations is also different. When new products are introduced, the environment in the sales areas must be considered, and fully comply with the requirements of laws and regulations that the region pays attention to. Achieve a vast market.
1. Meet the new standard test project for photovoltaic inverter
Standard test items, such as conversion efficiency measurement, maximum power point tracking efficiency measurement, output overvoltage protection, etc... These test items have been listed in various important regulations, such as EN50530, UL1741, CGC/GF004, JETGR0002, GB/ T19939, IEEE1547 & IEEE 1547.1, etc. These are the specifications that are highly valued in various regions of the world and also make these test items a basic requirement for the ex-factory test of photovoltaic inverters. Therefore, they are included in the standard test items for tester systems. It is very necessary for the user to use it directly. Otherwise, the customer will not be able to perform the test and certification according to the requirements of the new standard, or the old one must be eliminated and a new tester must be purchased to meet the requirements.
2. Generate more accurate I–V curves
For the PV inverter input conditions, the Sandia/EN50530 two regulations make clear requirements. Both have different ways to define the IV curve at the input of the inverter. This requires the automatic test system of the inverter to pass through the software. The integration of firmware, firmware and hardware, and the simulation of IV curves of various characteristics can create fully compliant input conditions, so that the data of all test items will be more convincing.
The Chroma8000 automatic test system is a general-purpose automatic test system developed by Chimao Electronics and can be applied to the testing of various power supply products. In recent years, along with the development of the green energy industry, 8491/8000 PV/8000EV and so on have been derived. A dedicated automatic test system for green energy applications, where 8000 PV is locked into the test application of photovoltaic inverters.
