- Double Safety, Zero Compromise: Each PJERJZN combiner box is pre-loaded with 1000V DC 40A mini circuit breakers (MCB) and 20-40KA surge protectors (SPD) – no cheap fuses! The dual-protection system instantly cuts off overloads/short circuits and blocks lightning surges (up to 40kA), 4X safer than basic 500V boxes
- Flexible Power for Any Solar Project: Choose 1-in-1-out (small cabins), 2-in-2-out (RVs/boats), 3String or 4String (large rooftops) – all support 1000V DC input and 40A continuous current. Scale your system effortlessly: A 4-in-4-out box handles 15.2kW at 48V, crushing 500V competitors’ 1.4kW limits
- Quick-Diagnose Design: The full-view transparent window lets you inspect MCB switches and SPD indicators in real-time – no need to open the box! Spot lightning strikes (red SPD light) or tripped breakers instantly, even during heavy rain
- Unbreakable Build: Made with military-grade PC+ABS (not basic ABS), the enclosure withstands UV rays, salt spray, and -40°C to +80°C extremes. IP65 seals keep dust/water out, while fire-retardant materials protect against arc faults
- 15-Minute DIY Installation: includes pre-wired 9~10AWG cables, 4 FREE MC4 connectors, and labeled terminals. Mount on walls or panels with included brackets. Tool-free DIN rails let you replace SPDs/MCBs in seconds – no electrician needed
