What is the WorldSunLight collection?
The WorldSunLight collection brings together a technical catalog of electrical components for solar installations: DC and AC protections, isolation, watertight connection, and enclosures. Its objective is to facilitate safe, organized, and best-practice-compliant PV panels for residential and industrial self-consumption.
Advantages and limitations
- Safety and compliance: equipment sized for photovoltaics (up to 600–1000 V DC depending on reference) and 230/400 V networks.
- Standardization: protection kits that speed up installation and minimize errors.
- Durability: IP65 panels and accessories suitable for outdoor use.
- Limitations: requires correct calculation of Voc, Isc, and breaking capacity; adjust the kit to the inverter and actual number of strings.
Applications
- Protection in direct current between PV generator and regulator/inverter.
- Protection in alternating current at the inverter output and main panel.
- Safe isolation for maintenance and emergencies.
- Connection with certified connectors and terminals.
How to choose
- In DC: calculate Voc at minimum temperature and Isc with coefficient; select appropriate fuse/circuit breaker and SPD type II or I+II.
- In AC: define inverter power, current, and single/three-phase scheme; use curve C and ratings with selectivity.
- Panels: allow space for expansion and accessories in IP65 panels.
- Connection: pair original MC4 connectors and certified crimping tools.
Indicative specifications
| Typical DC range | Up to 600–1000 V DC (depending on equipment) |
| AC range | 230 V single-phase / 400 V three-phase |
| Types | Circuit breaker, isolator, 10×38/MEGA fuse, SPD II/I+II |
| Enclosures | IP65, 1–24 modules with DIN rail |
| Accessories | MC4, terminals, cable glands, and keys |
Indicative values: always check voltages, currents, and breaking capacity in each datasheet.
Best practices
- Coordinate SPDs in DC and AC and minimize lengths between SPD and protected equipment.
- Size sections according to current and voltage drop; respect tightening torques.
- Ensure selectivity by grading ratings from string to main panel.
- Identify circuits with labeling and diagrams inside the panel.
