5. How V-Trust Controls Inverter Quality

V-Trust delivers comprehensive inverter inspection services, ensuring consistent product quality and regulatory compliance. Our quality control solutions cover all stages of inverter production, including Sample Checks, Production Monitoring , During Production Inspection , Pre-Shipment Inspection , and Container Loading Supervision , reducing the risk of product failures and costly recalls.

Sample Check

Our engineers evaluate inverter samples for safety, technical performance, and certificates. We benchmark performance against your specs to identify optimal suppliers.

Production Monitoring

We conduct on-site oversight during critical stages like SMT assembly, wave soldering, and conformal coating. We verify heatsink mounting torque, firmware flashing logs, and burn-in test parameters.

During Production Inspection

Once at least 10% of the inverter order is completed, our team performs a mid-production inspection to evaluate:

• PCB contamination control
• Transformer temperature rise
• Grounding continuity
• MPPT tracking accuracy

This early-stage inspection helps minimize rework and avoids late-stage surprises. 

Pre-Shipment Inspection

Before shipping, we perform a thorough final inspection of your electric bikes to confirm:

• Safety: Hi-pot, IP65 validation
• Performance: Efficiency curve, grid sync
• Compliance: CE/UL markings, RoHS documentation
• Packaging: Drop-test certification 

Container Loading Supervision

We verify pallet stacking, moisture barrier installation, and hazardous goods segregation. Container floor conditions and secure lashing are monitored to prevent damage or corrosion during transit.
