Protection boxes are essential for the safe operation of solar and hybrid energy systems. These units contain the system's electrical protection components, such as surge arresters, disconnect switches, fuses and current protection devices, which prevent damage in the event of overvoltage, short circuit or overcurrent. Choosing the right protection box is crucial for the longevity and safety of the system.

Most protection boxes have an IP65 or higher enclosure, making them suitable for both indoor and outdoor installation. Manufacturers offer pre-assembled, tested solutions that are compatible with both DC and AC side installations. These boxes are available for single-phase and three-phase systems, as well as separate versions for protecting hybrid inverters and battery systems.
