As the "heart" of photovoltaic power generation, the health of the inverter is closely related to the smooth operation of the photovoltaic power generation system. It is necessary to understand common inverter alarms and accurately determine the cause of inverter alarms. 1. Inverter alarms not caused by internal devices If the screen or APP shows that the EEPROM fails, it can usually be repaired b...
First of all, the basis of the working principle of solar cells is the photovoltaic effect of the semiconductor PN junction. The so-called photovoltaic effect is an effect in which electromotive force and current are generated when the object is illuminated, the state of charge distribution in the object changes. When sunlight or other light hits the PN junction of the semiconductor, a voltage app...
Energy storage converter, also known as bidirectional energy storage inverter, English name PCS (Power Conversion System), is used in AC-coupled energy storage systems such as grid-connected energy storage and micro-grid energy storage, connecting battery packs and power grids (or load), it is a device that realizes bidirectional conversion of electric energy. It can not only invert the DC power o...
There are various currents inside the cell, such as dark current, reverse current, leakage current, etc. Various currents have a greater or lesser impact on the power of solar panels. Distinguishing the characteristics of various currents can identify the cause of abnormal solar panel power and help solve the problem completely. dark current Dark current (DarkCurrent), also known as unilluminated ...
Reasons for low insulation resistance: When the solar panels or DC cables and joints are damaged or the insulation layer is aging, the problem of low insulation resistance is easy to occur. When the DC cable passes through the bridge, since the edge of the metal bridge may have barbs, the outer insulation of the cable may be damaged during the threading process, resulting in leakage to the ground....
