1-String 500VDC Photovoltaic Panel with Full Protection
The protection panel for photovoltaic systems with 1 string at 500VDC ensures the safety of the entire solar installation against overvoltages, short circuits, and atmospheric discharges. Designed for residential and semi-industrial installations, this equipment combines a DC circuit breaker, fuses, and surge arresters in a single, sealed, ready-to-mount box. It is the complete solution for protecting the inverter and photovoltaic panels in a single-string panel system.
What you get with this product
- Integrated triple protection — DC circuit breaker, 1000VDC fuses, and DALBI LD-40 surge arresters, all in one enclosure
- Fast disconnection in case of emergency or maintenance, without risks to the user or equipment
- Sealed box with IP65 protection rating, water and dust resistant, suitable for outdoor mounting on photovoltaic structures
- MC4 connectors pre-installed on the DC input, compatible with standard solar panel cables — no additional adapters
- Compatible with photovoltaic systems up to 500VDC, covering typical residential configurations with a single string of panels
- Compact design with transparent cover and lock — visualize component status without opening the panel
How it works and how to install it
The panel is mounted on the wall or on the panel structure, between the string of photovoltaic panels and the inverter. The DC cables from the panels are connected via the MC4 connectors on the bottom of the box, and the DC output goes to the inverter through the sealed cable glands. All protection components are already assembled and wired internally — installation is limited to connecting the input and output cables, without interventions inside the panel. It is recommended that the work be carried out by a certified electrician.
Frequently Asked Questions
Is it compatible with any solar inverter?
Yes, the panel is compatible with standard solar inverters that accept DC input up to 500V, regardless of the manufacturer.
Can I mount the panel outdoors, on the roof or on a wall exposed to rain?
Yes, the enclosure has IP65 protection, which means it is sealed against water jets and dust, and is designed for outdoor installation.
What happens if a panel is struck by lightning — does the panel protect the inverter?
The included DALBI LD-40 surge arresters absorb voltage spikes caused by atmospheric discharges or switching, protecting the inverter and other equipment in the installation.
