The equipment can be used for the I-V test of various high efficient solar module (PERC, N, HIT, IBC) and MBB The pulse width is 200ms (10-200ms continuous adjustable). It can effectively overcome this kind of high efficiency battery capacitance response and ensure the accuracy of test data; also it can be used to ensure the accuracy of the test data. In order to test the conventional P type single and poly-crystalline solar modules, one machine is used as the first choice for the large laboratories, testing and certification institutions and high efficiency battery production enterprises. The same type of intelligent electronic load equipped with the same type of equipment has been applied in NIM.
