The circuit protection section uses a photovoltaic grid-connected circuit breaker and a ring-type isolating switch, with a two-level lightning protection system. Its protection rating is IP65, the same as that of string inverters, meeting the requirements for outdoor installation and providing protection against water, dust, UV, and salt corrosion. The internal structure of this product is simple and clear, with neat and well-organized wiring. It is highly reliable and easy to maintain. Designed for outdoor wall-mounted installation, it can adapt to various harsh environments.
