A detailed engineering review of civil and electrical designs if they meet applicable technical standards and all components are arranged in accordance with their specifications. With the view that engineering is optimized for maximum system yield, evaluations are performed at different levels; DC side, Low voltage AC side, Medium/High voltage AC side (including substations, switchyards, and interconnection facilities). Major activities during the review include;
- Inverters and transformer arrangement
- String plan review
- Inverter configuration check
- Check for current overload and reverse current
- DC/AC cable dimensioning and management
- Equipotential bonding/lightning protection
- Single-line diagram
- Transformer loading
- HV-side assessment and selective analysis
- Distribution cabinet (fuse sizing and derating)
- Monitoring arrangement
