Protect your solar investment and simplify installation with a compact DC protection unit designed for reliable overvoltage and shortcircuit defense. Key benefits Prevent system damage: Dedicated voltage arrester and builtin circuit breaker reduce risk from surges and shortcircuit faults, protecting panels, inverters, and batteries. Reduce downtime: Onsite fuse and breaker protection isolates faults quickly so you can service the system without risking additional components. Secure access: Integrated password security lock limits unauthorized access and prevents tampering with critical DC connections. Fast, adaptable installation: Includes a mounting buckle for straightforward attachment to standard surfaces and compatibility with a wide range of solar panels and installation tools. Core features voltage arrester for surge protection on the DC side DC fuse box with a 15A fuse to protect wiring and downstream equipment Circuit breaker providing shortcircuit fault protection and manual isolation Mounting buckle for easy installation on regular surfaces Password security lock for controlled access Broad compatibility with ongrid and offgrid systems, PV arrays, RV solar systems, and multiple solar panel brands Practical use scenarios Residential rooftop (ongrid): Use this unit between your PV array and inverter to guard against lightninginduced surges and wiring faults, minimizing costs and downtime. Offgrid cabin or tiny home: Provide essential DC protection for battery charging circuits and charge controllers in standalone systems. RV or marine solar system: Install on an RV or boat to secure panel arrays, protect wiring during variable conditions, and control access to DC connections. Why choose this unit Integrates surge arresting, fuse protection (15A), and a circuit breaker into a single, easytomount module, reducing parts and installation time. Designed to work with a variety of solar setups—ongrid or offgrid—and with most solar panel brands and installation tools. Delivers straightforward, reliable protection and controlled access without complicated configuration. Specifications to note Includes dedicated voltage arrester, DC fuse box with a 15A fuse, and circuit breaker for shortcircuit fault protection Mounting buckle included for installation on regular surfaces Password security lock for access control Compatible with ongrid and offgrid solar systems, PV arrays, and RV solar energy systems If you need a compact, multifunction DC protection solution that simplifies installation and secures your PV system against common electrical faults, this unit provides the essential protections required for safe, reliable operation.
