As per product's size and thickness and materials.PV Inverter Sheet Metal Enclosure
Product Description: String inverter enclosure, PV grid-tied inverter housing, PV inverter
Model: OEM/ODM
Base Materials: Hot-dip galvanized steel sheet, cold-rolled steel sheet (SPCC), aluminum alloy sheet, Al-Zn coated sheet
Manufacturing Process:
1. Material Cutting: Cutting sheets to standard dimensions using CNC shearing machines;
2. CNC Punching / Laser Cutting: Machining of oval display cutouts, cable entry holes, screw mounting holes, and ventilation vents;
3. Press-fitting (Hardware Insertion): Press-fitting of nuts and studs;
4. Sheet Metal Bending: Integrated bending to form the enclosure sidewalls, door frame, and rounded corner profiles;
5. Welding: Spot welding or seamless full-seam welding of enclosure corners to ensure a watertight seal;
6. Grinding and Leveling: Grinding and polishing weld seams; removing burrs and sharp edges;
7. Surface Coating/Finishing;
8. Quality Inspection, Cleaning, and Packaging for Shipment;

Precision: Dimensional tolerances for length, width, and thickness: ±0.3–0.5 mm; positional tolerances for cutouts: ±0.2 mm; IP65 rating.
Surface Treatment:
1. Electrostatic powder coating (Colors: RAL, PANTONE, GSB05, or custom); features a thick, impact-resistant, UV-resistant, waterproof, and rust-proof finish suitable for outdoor use.
2. Liquid painting: Thinner coating, wide color range, lower cost; lower weather resistance compared to powder coating; typically used for indoor applications or short-term use.
3. Brushed stainless steel + passivation: For stainless steel substrates only; retains natural metallic texture; excellent corrosion resistance; ideal for coastal regions.
4. Anodizing (aluminum alloy enclosures): Exclusive to aluminum; offers wear resistance and good heat dissipation; used for lightweight, high-end charging station housings.
Unit Price: Quoted based on drawings.
Packaging:
1. Interior walls fully lined with EPE foam; extra cushioning and protection for cutouts and corners.
2. Desiccant included inside to prevent rust caused by condensation/moisture during ocean freight.
3. Entire unit wrapped in moisture-proof PE film.
4. Packed in heavy-duty export-grade corrugated cardboard boxes; reinforced with wooden corner protectors.
5. Large-volume palletized shipments: ISPM-15 heat-treated solid wood pallets secured with stretch wrap.
6. Large items/multiple units: Sealed packaging in fumigation-free plywood (IPPC-compliant) crates.

Logistics:
Sea freight, air freight, international express (DHL, FedEx, UPS, TNT), rail transport (primarily China-Europe freight trains), and road transport (short-haul cross-border trade with neighboring countries).
