PV Combiner Box &
Solar Electrical
Components
TrilPeak is expanding its solar protection portfolio to include PV combiner boxes, DC circuit breakers, PV fuses, DC disconnect switches, and waterproof enclosures — engineered for inverter OEMs and EPC contractors. Products are in development and will be added to our solar PV DC SPD lineup.
What's Coming — PV & Electrical Component Range
The following products are planned for this category. Each will ship CE certified and is designed to integrate directly with TrilPeak's existing PV DC surge protectors for complete solar system protection from one supplier.
Combines multiple PV string inputs into a single DC output. Integrates string fusing, reverse current blocking, and optional SPD slot for a complete overcurrent and surge protection assembly.
DC-rated miniature circuit breakers for overcurrent protection in solar PV arrays, combiner boxes, and BESS systems. Poles and ampere ratings sized for common inverter OEM specs.
Cylindrical gPV solar fuses and fuse holders for string overcurrent protection inside combiner boxes and junction boxes. Rated for DC applications per IEC 60269-6.
Load-break DC disconnect switches for safe isolation of PV arrays, combiner boxes, and inverter inputs. Lockable handle for maintenance safety compliance.
A bundled kit pairing a PV DC SPD with combiner box, fuses, and disconnect switch. Designed for inverter OEMs who require a pre-validated, single-SKU protection assembly for their systems.
IP65/IP66 ABS and polycarbonate enclosures for field-mounting protection components in outdoor solar installations. Matched cable glands for watertight conductor entry.
PV & Electrical Component Range — Summary
All products in this range are designed to be used alongside TrilPeak's PV DC surge protectors for a complete solar system protection stack from a single CE-certified factory.

Complete Solar Protection from One Factory
TrilPeak already supplies PV DC surge protectors to inverter OEMs and EPC contractors across 40+ markets. The PV & Electrical Components range extends this to cover every overcurrent and isolation device needed for a compliant solar installation.
SPDs, combiner boxes, breakers, and fuses from one CE-certified factory. One PO, one document set, one engineering contact for the complete solar protection stack.
Private label and custom specification available across the full range. TrilPeak's OEM programme and ODM service extend to all electrical components.
Every component ships with CE documentation. Pre-validated kits reduce inverter OEM integration effort and shorten certification timelines for new product designs.
Solar PV Protection Products — Ready to Ship
While PV & Electrical Components are in development, TrilPeak's full range of solar PV surge protective devices is available now with CE certification, OEM labelling, and global shipping.
