Solar Inverter PCBA for PV Power Conversion and Energy Systems

Solar Inverter PCBA for PV Power Systems

This solar inverter PCBA is designed for photovoltaic power conversion equipment, including residential, commercial and utility-scale solar systems. The assembly can be customized for inverter control boards, MPPT power boards and DC/AC conversion modules.

The manufacturing process covers PCB fabrication, component sourcing, SMT and DIP assembly, functional testing and turnkey PCBA production. High-current PCB options are available for applications that require stable power handling and thermal performance.

High-Current PCB for Solar Inverter Applications

The PCB can be manufactured with 1oz to 6oz copper, with 2oz to 6oz options available for high-current inverter circuits. FR4, aluminum and IMS materials are supported, with 1 to 8 PCB layers depending on the design requirements.

Surface finish options include ENIG, lead-free HASL, OSP and immersion silver.

SMT and DIP Assembly

The solar inverter PCBA supports SMT, DIP and mixed assembly for different power and control circuit designs. Assembly capability covers small SMD devices, QFN, BGA and through-hole power components.

This allows the same manufacturing process to accommodate control circuits, driver circuits and power sections within one inverter board.

MPPT and DC/AC Power Conversion

The PCBA can be used for MPPT control boards and DC/AC conversion modules in photovoltaic inverter systems. The source specification lists a PV-side input range of DC 90-550V and an AC input range of 176-264V, with customizable rated output power from 500W to 60kW.

The listed conversion efficiency is ≥98% for the MPPT stage and ≥96% for the inverter stage, depending on the specific design and operating conditions.

Testing and Quality Control

Solar inverter power boards require electrical and thermal testing before production delivery. The manufacturing process supports AOI, X-Ray, ICT and functional testing, together with a 48-hour burn-in or aging test under rated load.

DFM review can also be performed before production to identify manufacturing issues and improve production yield.

Custom Solar Inverter PCBA Manufacturing

The PCBA can be manufactured from customer-supplied Gerber files, BOM and assembly drawings. Component sourcing, PCB fabrication, assembly and functional testing can be combined into a turnkey production process.

Prototype quantities, small batches and larger production volumes are supported. The source page lists prototype production from 1-10 pieces and no strict MOQ.
