As the running time of PV plants increase, the DC line slowly ages, and the waterproof performance of the DC terminal (MC4 terminal) deteriorates. As a result, the insulation impedance of the DC line is too low, or the positive and negative terminals are short circuited to the ground. Either way, major failures may occur, affecting the generation of electricity.
Aging PV plants and deteriorating MC4 terminals can cause low insulation impedance and major failures. This Solis seminar will unveil the piecewise method, a powerful technique for pinpointing ground fault points. Learn how to improve troubleshooting speed while reducing the need for extensive manpower here.
