Energy Storage Inverter PCBA OEM Service: Full-Stack Engineering for High-Power Reliability
Our turnkey OEM service specializes in 4-layer 4Oz copper PCBAs engineered for 1500V DC bus voltages and 200A continuous currents, achieving <20mΩ trace resistance in DC-link pathways. This reduces conduction losses by 50% versus standard 2Oz designs, enabling 99.5% peak efficiency in 500kW–2MW inverters while maintaining ΔT <5°C under full load at 60°C ambient—critical for outdoor utility-scale storage and EV fast-charging integration.
Technical Highlights
- 1500V DC Isolation: 6mm creepage distances and five-layer slot isolation exceed IEC 62109-3 requirements for ultra-high-voltage systems.
- SiC MOSFET Optimization: Low-inductance layout (<3nH) and driver circuit integration reduce switching losses by 35%, enabling 100kHz+ operation.
- EMI/EMC Compliance: Shielded inductor chambers and multi-stage filtering pass CISPR 32 Class B and FCC Part 15 without additional components.
Thermal & Environmental Robustness
- IP69K Thermal Encapsulation: Two-part epoxy potting with graphene-enhanced thermal conductivity (5W/m·K) ensures -40°C to +100°C operation.
- Direct Liquid Cooling (DLC) Support: Micro-channel cold plates integrated into PCBA reduce thermal resistance to 0.8°C/W at 1MW output.
- HALT/HASS Validated: 2000-hour continuous testing under 85°C/85%RH and 50g vibration ensures 20-year lifespan.
OEM Capabilities
- 4-Week Turnkey Delivery: From schematic design to 10,000-unit production, including DFM/DFT optimization and functional testing.
- AOI + X-Ray + ICT: 99.998% defect detection for 01005–BGA packages and 0.2mm pitch fine-pitch components.
- Certifications: UL 1741 SA, IEC 62109-3, ISO 13849 (PLd), CE, RoHS.
Ideal For:
- Utility-scale battery energy storage systems (BESS)
- EV fast-charging stations with V2G capability
- Industrial microgrids with renewable integration
