Audit calculation assumptions

Defaults

• Safety factor: 1.25
• Peak sun hours: 4.5
• PV performance factor: 0.8
• Battery depth of discharge: 0.9
• PV recovery reserve: 1.25
• Backup target hours: 8

All assumptions are editable per audit.

Load item calculations

• Total watts = quantity × watts per unit
• Daily energy Wh = total watts × runtime hours
• Day energy Wh = total watts × day runtime hours
• Night energy Wh = total watts × night runtime hours
• Estimated surge watts = total watts × surge factor

Audit totals

• Total running load counts inverter-backed load items.
• Estimated surge load sums inverter-backed item surge values.
• Daily, day, and night energy demand sum all load items.
• Critical and non-critical load watts split items by critical status.
• Recommended inverter kW = larger of safety-adjusted running load or estimated surge load, divided by 1000.
• Recommended battery kWh = critical load watts × backup target hours × safety factor ÷ battery depth of discharge ÷ 1000.
• Recommended solar kWp = daily energy demand × PV recovery reserve ÷ peak sun hours ÷ PV performance factor ÷ 1000.

Generated findings

The system creates unresolved findings for:

• audit not linked to a CRM record
• missing wattage
• missing runtime
• zero quantity
• high surge factor
• battery recommendation below night load requirement
• missing solar assumption inputs such as peak sun hours

Resolved system findings are retained historically. If the same issue still exists after a later calculation refresh, a new unresolved finding can be generated.
