The PV Solar Straight Inline Fuse Connector is a compact and reliable solution for protecting photovoltaic systems from overcurrent damage. Designed with MC4 compatibility, it combines a fuse holder and connector in one unit, making installation quick and hassle-free. With waterproof IP67 protection, UV resistance, and replaceable fuses (10A–30A), it ensures safe and efficient operation in both on-grid and off-grid solar applications.
Description
PV Solar Straight Inline Fuse Connectors are specially designed to provide reliable overcurrent protection for solar PV systems. They combine the function of a fuse holder and MC4-type solar connector in a compact inline design. These connectors ensure safety, prevent damage to panels and inverters, and are easy to install without additional fuse holders.
