FAQs: Aluminum Extrusion Connectors for Solar Applications
The function of solar inverter housings is to protect the enclosures that house the systems responsible for converting DC to AC power. They shield the electronics from the weather while also taking care of heat and electromagnetic emission control. These enclosures come in different types: IP65-rated string inverter enclosures-either for residential or commercial systems that are 3 to 100 kW, central inverter cabinets for utility-scale installations 500 kW to 3 MW that are walk-in and have active cooling. There are micro inverter housings for module level power electronics rated 200 to 400 watts also IP67 rated, hybrid inverter cases that integrate with battery management systems, outdoor rated NEMA 3R and 4X enclosures for extreme conditions, hybrid inverters that integrate with battery management systems, and even wall mount and ground mount configurations. There are also optimizer enclosures, DC combiner boxes with integrated disconnects, and monitoring system enclosures that have special requirements of corrosion resistance, UV stability, and thermal management for extreme cold of minus 40 to plus 60 degrees Celsius.
Aluminum 6061-T6, 5052, and die-cast ADC12 provide excellent thermal conductivity of 167 to 201 W/m-K enabling passive heat dissipation reducing internal temperatures by 15 to 25°C, lightweight construction simplifying installation, superior corrosion resistance to outdoor weathering, natural EMI shielding effectiveness exceeding 80 dB, and recyclability. Stainless steel 304 and 316 offer maximum corrosion resistance for coastal installations within 1 km of saltwater, superior strength for large cabinets, excellent EMI shielding, and 25-year durability without protective coatings. Galvanized steel delivers cost-effectiveness for large utility-scale cabinets, adequate strength and rigidity, electromagnetic shielding, and corrosion protection through zinc coating providing 15 to 20 year outdoor life.
Enclosure profiles are created using Precision CNC milling along with incorporation of mounting flanges, cable entry cutouts, and ventilation openings while making sure to keep the tolerances ±0.005 inches. For the integrity of the IP rating, drilling takes care of cable gland mounting holes with position accuracy ±1mm. Tapping makes threaded holes for mounting the equipment and for assembly of the enclosures. Pocket milling does the recessed areas for the displays, connectors, and internal mounting rails. For integrated heat sinks, fin arrays are machined in the walls of the enclosures. For thermal performance, the gasket groove milling does the channels to the specified dimensions ±0.2mm for control of the seal compression. All edges are deburred for safe handling and edge sealing of the gasket.
Tolerances for solar inverter housings from 200 watts to 3 megawatts with IP54 to IP67 environmental protection include, cable gland holes at ±1mm for sealing, mounting surface flatness of 1mm per meter to ensure proper installation, fin spacing of ±0.5mm for heat sink, groove dimensions of ±0.2mm for sealing to IP rated 65/67, outer dimensions of ±2mm and overall enclosure width of ±2mm.
Yes, we provide rapid prototyping to verify fit and test assembly, with same-day CAD-to-part capability available for critical projects. For custom automation cells and research platforms, we perform low-volume production of 20 to 500 brackets. For standardized robot models, we perform high-volume production of thousands to tens of thousands of brackets annually, incorporating complete dimensional inspection, flatness verification, and material certifications.
All components are manufactured under ISO 9001 certified quality management systems with complete traceable documentation including composition certificates and corrosion resistance data, dimensional verification against enclosure specifications, IP rating validation testing documentation, and adherence to solar industry requirements including IEC 62109 for inverter safety, UL 1741 for grid-connected inverters, IEC 60529 for IP rating classification, NEMA standards for enclosure types, salt spray resistance per ASTM B117, UV resistance per ASTM G154, and environmental compliance with RoHS and REACH ensuring 25-year outdoor durability and safe operation in residential, commercial, and utility-scale installations. What surface finishing options are available? Finishes include powder coating offering durable UV-resistant protective layers in custom colors with coating thickness from 60 to 120 microns providing 15-year outdoor protection. Anodizing on aluminum providing corrosion resistance and electrical insulation in clear, black, or colored finishes. Wet paint systems for cost-effective protection. E-coating for superior corrosion resistance in internal surfaces and hard-to-reach areas, zinc plating on steel for supplemental corrosion protection. Specialized treatments include chromate conversion coating, textured finishes for reduced solar heat gain, anti-graffiti coatings for vandalism resistance, and finishing for controlled access installations.
We provide comprehensive finishing solutions tailored to aerospace requirements:
Anodizing (Type II and Type III)
Passivation for corrosion resistance
Precision polishing for aerodynamic surfaces
Custom protective coatings and thermal barriers

For regular inverter housings based on existing designs, it takes about 12 to 18 business days to complete the machining, surface treating, assembly prep, and the IP rating check. For custom complex housings with cooling systems and other custom features, it can take 4 to 6 weeks. As for prototype inverter housings used for thermal and environmental testing, they can be done in 10 to 14 days, depending on how fast the needed materials are available and the coating can take longer.
Absolutely! We build custom inverter housings for solar systems that range from 200 watt micro inverters all the way to 3 megawatt central inverters. We also build for hot climates, extreme temperatures up to about 60 degrees Celsius, coastal areas and construct with lightweight materials for easy wall-mount installation. We've designed units for space-restricted rooftops, expand IP67 sealed units for dusty areas or wash- down applications, and designed architecturally integrated units with smart monitoring and battery-ready space.
With precise gasket groove dimensions within ±0.2mm, seal compression to achieve IP65/67 rating is made possible, preventing moisture and dust ingress. This is important as it protects the electronics from failing, and it maintains protection for 25 years when exposed outdoors. Accurate positioning within ±1mm of the cable glands also enables proper installation which maintains the IP rating integrity for all penetrations. The integrated heat sink geometry with controlled fin spacing optimizes convection to reduce internal temperatures of the electronics by 15 to 25°C and improves the conversion efficiency by 1 to 2%, which prolongs the life of the electronics. Controlled flatness of the external surfaces also allows proper mounting to prevent enclosure distortion and seal compromising. Ventilation openings are placed to maximize airflow, but the enclosure protects against airborne particulates. Quality aluminum is used for the construction of the housing to meet the electromagnetic compatibility standards as it provides more than 80 dB of electromagnetic shielding effectiveness. The housing is designed to withstand more than 1000 hours of salt spray testing. The enclosure also provides for convective cooling which is designed to dissipate 50 to 500 watts of thermal load. This improves reliability and decreases maintenance as active cooling is not required.
Precision manufacturing makes it possible to safeguard solar inverters for rooftop systems with a capacity of 3–10 kW for households, 20–100 kW for commercial use, and 500 kW to 3 MW utility solar farms. These require protection from -40 to +60°C, and humidity protection of 100% for 25 years outdoor exposure. Power conversion efficiency of 98 to 99% is maintained annually with electromagnetic compatibility and safe operational endurance throughout the solar system’s life. In 25 years of outdoor exposure, protection from humidity and environmental factors is withstanding electromagnetic compatibility at FCC Part 15 and EN 55011.
