Can boxes be configured and branded to our project spec?

Yes. We build to your single-line diagram — string inputs and outputs, fuse and breaker ratings, isolator type, SPD class, enclosure material and color, and printed branding. Provide your specification for a sample and tooling timeline.

Which certifications do your combiner boxes carry?

Components and assemblies are built to the relevant IEC standards (IEC 60269-6 PV fuses, IEC 61643-31 DC SPDs) with CE and RoHS conformity and test reports. For North American projects we can align to UL 1741 and supply UL-recognized components on request — confirm the destination market early.

What is your sample and MOQ policy?

A paid sample or pilot unit is available before volume orders, typically credited against the first order. MOQ depends on configuration complexity; standard builds carry a lower minimum than fully custom enclosures. Request a project-specific quotation.

PV Combiner Box Buying Guide for Global Procurement

Size the combiner box around the system voltage and string count of the array. Confirm the maximum DC voltage (600 V residential, 1000 V commercial, 1500 V utility-scale) and that every DC component is rated for it — using an AC-rated isolator or breaker on a DC string is a serious arc-flash hazard. Match the number of string inputs and outputs, the per-string protection (gPV fuses to IEC 60269-6), and the main DC disconnect: a load-break isolator or DC breaker with a proper arc-extinguishing chamber for safe on-load switching during maintenance.

Protection and enclosure rating decide field reliability. A Type 2 DC SPD (e.g. 40 kA, fail-safe Y) guards the array and inverter against induced surges. The enclosure must carry the right ingress and material rating for the environment — IP65/IP66 with UV-stabilized, flame-retardant polycarbonate, or powder-coated steel for harsh outdoor duty. Pre-wired busbars, correct conductor sizing, and proper earthing cut installation time and inspection risk. For North American projects, confirm UL 1741 alignment up front.

Industry Application Scenarios

Residential Rooftop Systems

Compact 1–2 string IP65 boxes integrate a DC isolator and 40 kA SPD in one pre-wired enclosure, simplifying rooftop installation and inspection sign-off.

Commercial & Industrial (C&I) Arrays

Multi-string boxes with gPV fuses, a load-break DC switch, and surge protection consolidate string protection for large rooftop and carport systems at 1000 V.

Utility-Scale Ground Mount

1500 V-rated steel-enclosure combiners with high string counts and high-current DC breakers aggregate array sections while withstanding harsh outdoor exposure.

Battery Storage & Hybrid Inverter DC Side

Combiners with redundant breakers and SPDs protect the DC side of hybrid and storage installations where multiple sources share a common bus.
