Description

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

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $41 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for Pjerjzn products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
