Solar Enclosures

Solar enclosures are purpose-engineered to protect power electronics and monitoring systems in photovoltaic installations exposed to decades of UV radiation, thermal cycling, wind-driven moisture, and corrosive atmospheres. Our enclosures are designed around the specific failure modes observed in utility-scale and rooftop solar deployments including gasket degradation, galvanic corrosion at cable entry points, and internal heat accumulation in inverter housings.

Product Description

Designed for decades of unattended outdoor service, our solar enclosures integrate robust sealing architectures, high-conductivity aluminum alloys, and UV-stabilized surface treatments to shield inverters, MPPT controllers, combiner boxes, and monitoring electronics from environmental degradation. Each enclosure accommodates DIN rail mounting systems, multi-entry cable gland plates, and field-serviceable access configurations while meeting IEC 62262, IEC 60529, and UL 50E compliance standards applicable to solar Balance-of-System (BOS) components.

UV Stability & Weathering

UV-resistant polyester powder coat and hard-anodized surfaces; compliant with ISO 4892-2 accelerated UV aging; rated for 25+ year outdoor PV exposure

Thermal Management

Passive conduction via aluminum body (205 W/m·K); optional extruded fin profiles and bolt-on heatsink interfaces for inverter and charge controller heat dissipation

Corrosion & Salt Spray Resistance

>1000 hours per ASTM B117 salt spray test (with hard anodizing and sealing); suitable for coastal solar farms and high-humidity tropical environments

Sealing System

Silicone/FKM compression gaskets with custom groove profiles; IP66/IP67-rated cable entry gland plates; sustained seal integrity under thermal cycling –40°C to +75°C

EMI/RFI Shielding

Up to 40 dB attenuation across PV inverter switching frequencies (kHz–MHz range); conductive bonding design minimises conducted emissions and interference with monitoring electronics

Grounding & Bonding Points

Multiple M6/M8 grounding studs; Alodine-treated internal bonding surfaces for PV system earthing continuity; compliant with IEC 60364-7-712 solar PV earthing requirements

Cable Entry Management

Pre-punched and blank gland entry zones; compatible with M16–M63 metric cable glands; supports DC string wiring, AC output, data/comms, and earthing conductor segregation

Fire Resistance Rating

UL 94 V-0 rated internal insulation and gasket materials; suitable for battery-adjacent BESS and hybrid solar-storage enclosure applications per IEC 62933

Environmental Compliance

RoHS, REACH, and WEEE compliant; suitable for CE-marked solar system integration and IEC 61215 / IEC 61730 PV module installation environments

Load Bearing Capacity

Up to 120 kg static mounting load (varies by enclosure geometry, wall thickness, and mounting bracket configuration); pole-mount, pedestal-mount, and wall-mount options available

Technical Advantages

Aluminum’s high thermal conductivity, approximately 205 W/m·K, enables efficient conduction of internally generated heat across the enclosure body and outward to the surrounding air. For higher-density power electronics, our enclosures can be specified with extruded fin profiles or bolt-on heatsink interfaces that substantially increase the passive cooling surface area, reducing the risk of thermal derating, premature component degradation, or inverter shutdown during peak generation hours.

Frigate’s solar enclosures are engineered with IP65 to IP67-rated sealing systems using silicone and FKM gaskets with compression-rated groove profiles that maintain ingress protection through repeated thermal expansion and contraction cycles over decades. Surface finishes are selected and tested specifically for long-term outdoor performance: UV-resistant powder coats comply with ISO 4892-2 accelerated weathering standards.

Industry Application

Utility-Scale Solar Farms

Houses string inverters, DC combiner boxes, and SCADA communication interfaces across large ground-mounted PV arrays. Enclosures are specified for pedestal or ground-frame mounting, meeting NEMA 4X and IP66 requirements.

Rooftop & Commercial Solar Installations

Protects inverters and AC disconnect equipment on flat and pitched rooftop systems, where compact form factor, UV-resistant finishes, and low-profile mounting are critical for compliance with building codes and long-term aesthetic durability.

Solar Street Lighting & Public Infrastructure

Encloses charge controllers, battery management modules, and control electronics for standalone solar street lighting poles, traffic signal systems, and public park installations requiring vandal-resistant and weatherproof housings rated to IK08–IK10.

Off-Grid & Hybrid Solar–Storage Systems

Provides fire-rated (UL 94 V-0) housing for battery management systems, hybrid inverter-chargers, and DC protection devices in off-grid cabins, telecom towers, and island-mode microgrid installations where enclosure reliability is critical in the absence of grid backup.

Agricultural Solar (Agrivoltaics)

Deployed in agrivoltaic installations where enclosures are exposed to fertiliser spray, pesticide misting, and high ambient humidity. Materials and finishes are selected for chemical resistance and compliance with agricultural equipment safety standards.

EV Charging Infrastructure

Protects solar-integrated EV charging station power electronics, including charge controllers, protection relays, and billing communication modules, in outdoor carpark and roadside installations requiring IP66-rated enclosures with EMI management for clean grid injection.

Having Doubts? Our FAQ

Can Frigate make custom dimensions and internal layouts for our specific inverter or combiner box?

Yes. Frigate engineers enclosures to your exact requirements of external dimensions, DIN rail positions, gland plate layouts, and sub-panel provisions. Share your inverter datasheet or cabinet envelope drawing through the Get Quote form, and our team will send a feasibility assessment within 3 business days.

What certifications do Frigate's solar enclosures carry, and can I get documentation for project commissioning?

Enclosures are designed to IEC 60529 (IP rating), IEC 62262 (IK impact), and UL 50E (outdoor electrical enclosures), with finishes tested per ISO 4892-2 (UV) and ASTM B117 (salt spray). Material test certificates, IP test declarations, and dimensional inspection reports are available on request for commissioning packages.

Does Frigate provide DFM feedback before finalising the solar enclosure design for production?

Yes. Once you submit your design or requirements, our engineering team reviews it for manufacturability such as flagging issues like wall thickness tolerances, gland plate stress points, or finish compatibility with your specified alloy before any tooling or production is committed. This helps avoid costly design changes mid-order, especially for custom configurations. DFM review is included as part of the quoting process for medium orders and above.

How does Frigate manage cable entry for solar enclosures with mixed DC, AC, comms, and earthing cables?

Gland plates are designed with segregated entry zones for DC strings, AC output, data/comms (Modbus, RS485, Ethernet), and earthing conductors as per IEC 60364-7-712. Plates come pre-punched or blank, compatible with M16–M63 glands. Include your cable schedule in the quote request and we supply the correct gland configuration with the enclosure.

Which material is better for our solar project, aluminum or GRP, and does Frigate supply both?

Aluminum is preferred for most solar applications, it offers superior thermal conductivity for heat dissipation, structural rigidity, and longevity in high-irradiance environments. GRP is better suited where weight is a constraint or in highly corrosive coastal/chemical-heavy sites. Frigate supplies both; our application team can recommend the right choice based on your site conditions and inverter spec.
