ELNUIMEX 6-String Metal Solar Combiner Box — 20A Fuses, SPD & 63A Air Circuit Breaker

ELNUIMEX 6 String Metal Solar Combiner Box consolidates up to six PV strings with 20A rated fuses, built-in surge protection and a 63A air circuit breaker in a lockable IP65 metal enclosure.

Designed for small commercial and residential photovoltaic arrays, this metal combiner box simplifies wiring, protects equipment and gives clear visual status so installers and owners can manage multiple panel strings safely. The unit arrives pre-wired with solar-grade conductors, features an integrated ground lug and secures with a keyed lock—making it suitable for exposed rooftop or ground-mount systems where weather resistance and theft deterrence matter.

How does this combiner box protect my solar array?

The ELNUIMEX combiner integrates overcurrent devices and transient suppression so faults on any string won’t cascade into larger system damage. The 20A fuses isolate problematic strings, while the surge protective device helps divert harmful spikes away from inverters and sensitive electronics.

• Six replaceable 20A rated fuses for per-string overload isolation
• Surge Protective Device (SPD) to reduce lightning and surge risk
• 63A air circuit breaker for AC-side disconnection and fault clearing
• Visible indicator window to show fuse or enclosure status

Is it easy to install and maintain?

Yes—wiring is simplified because factory-installed solar cables and a dedicated ground lug reduce onsite prep and potential wiring errors. The metal housing includes mounting points and a keyed lock; routine maintenance is limited to fuse checks and SPD inspections through the indicator window.

• Pre-wired PV conductors to speed up field wiring
• Built-in ground connector for straightforward grounding
• Lockable metal enclosure to protect components and deter tampering
• Indicator window for quick visual checks without full access

Will this box stand up to outdoor conditions?

The enclosure is engineered for outdoor use with IP65 ingress protection and corrosion-resistant metal finish, so it withstands dust, rain and UV exposure. That makes it a practical choice for rooftop, pole-mounted or utility installations in varied climates.

• IP65-rated sealing against dust and water jets
• Durable metal spray finish resists weathering and corrosion
• Lock and gasketed door preserve internal components
• Suitable for exposed residential or rural facility deployments

What safety and operational features are included?

The unit combines multiple protective functions—rapid circuit disconnection, anti-reverse wiring layout and overcurrent safeguards—so the PV system can be serviced safely. Clear indicators and modular components make replacement and troubleshooting straightforward for electricians and maintenance teams.

• Rapid disconnection capability via fuses and breaker
• Anti-reverse wiring design to prevent incorrect string polarity
• SPD and fuse coordination to protect downstream equipment
• Modular parts for quick field service and replacement

Who is this for? Installers, system integrators and owners of small-to-medium PV arrays who need a compact, weatherproof way to combine multiple strings will find this ELNUIMEX combiner box useful. It’s aimed at rooftop residential systems, small commercial sites and remote utility installations where reliable surge protection, per-string isolation and a keyed metal enclosure improve safety and longevity. If you want a pre-wired, lockable metal combiner with clearly visible status indicators and standard protective devices, this model fits those requirements and speeds up commissioning and maintenance.
