Technical Notes
- ✓ Preliminary estimate only
- ✓ UPS runtime to be verified against manufacturer discharge tables
- ✓ Generator sizing to consider motor starting, load steps and derating
- ✓ Solar design to be verified with roof layout, shading and PV*SOL modelling
- ✓ Final design to comply with SANS 10142 and applicable municipal / SSEG requirements
