Leak detection is a key test for systems and components within the battery pack from cells, contactors, cooling system and the enclosure. Leaks in lithium-ion battery cells can shorten battery life and deplete energy capacity. Leaks also can allow moisture to enter the battery system.
The leakage current in floating PV is defined as the flow of currents in non-ideal materials of PV modules, cables, other supporting structures. If the distance between FPV modules and inverter increases, the leakage current will be more and it may effect on the operation of the system.
This could then trigger the leakage protection device if the system has such a device installed. Likely Reason: This fault indicates that the inverter and the leakage current protector have detected leakage current from the PV system to the ground.
It is easy to tell from the formula for leakage current (shown above) that the larger the PV panel area (S) , the higher the conductivity (ε) of air , and the shorter the distance (d) between the PV panel and ground or roof , the higher the leakage current will be.
Our photovoltaic systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
