Factory quality control: FAT & SAT
Every system is tested before it leaves the factory and again on site, with full documentation for traceability.
- IQC
Incoming quality control
Cells, BMS, PCS and key components are inspected on arrival before they enter production.
- IPQC
In-process control
Assembly, wiring and module grouping are checked at each production stage.
- FAT
Factory acceptance test
Every system is function- and safety-tested in the factory before dispatch, with a full FAT report.
- SAT
Site acceptance test
Cold and hot commissioning on site verifies grid compliance and safe operation.
- DOC
Traceability & documentation
Manufacturing, shipping and commissioning records provide end-to-end quality traceability.
