What makes a commercial battery pay back?
| ROI driver | What we measure | Best-fit sites |
|---|---|---|
| Peak-demand reduction | kVA peaks and demand tariff | Manufacturing, cold storage, large retail |
| Solar self-consumption | Solar exported during operating hours | Offices, schools, warehouses |
| Time-of-use arbitrage | Peak, shoulder and off-peak rates | Sites operating morning to evening |
| Backup resilience | Critical loads and outage cost | Refrigeration, hospitality, medical, logistics |
Commercial battery cost and system sizes
Commercial solar battery storage commonly starts around $35,000–$60,000 for a 30–50 kWh system and can reach $150,000–$300,000 for 200–500 kWh. The final price depends on inverter power, switchboard work, civil works, grid approvals, backup scope and the available state or tax incentives.
| Business profile | Typical battery | Indicative installed cost | Main outcome |
|---|---|---|---|
| Small business / retail | 30–60 kWh | $35,000–$75,000 | Solar self-consumption |
| Warehouse / hospitality | 60–150 kWh | $75,000–$160,000 | Demand shaving + backup |
| Manufacturing / logistics | 150–500 kWh | $150,000–$300,000 | Peak-demand reduction |
Commercial battery sizing inputs
We use 12 months of 30-minute interval data, solar generation, operating hours, tariff structure and site constraints. We then test battery power in kW, storage in kWh, cycling limits and the loads that must remain live during a blackout.
- Business electricity bills and 12 months of interval data
- Existing solar size, inverter and export limit
- Peak-demand charges and time-of-use tariff
- Operating hours, EV charging and refrigeration loads
- Available space, switchboard capacity and three-phase supply
- Backup priorities and acceptable outage duration
Three-phase commercial battery and backup design
Most commercial sites need three-phase power, but the battery capacity and inverter output solve different problems. We model kWh for energy shifting, kW for simultaneous loads and kVA for demand charges, then design a critical-load board for refrigeration, POS, EFTPOS, security or production equipment if blackout resilience is required.
Commercial solar battery systems by site size
| Business profile | Typical solar | Typical battery | Primary outcome |
|---|---|---|---|
| Small business / retail | 30–80 kW | 30–60 kWh | Solar self-consumption + evening load |
| Warehouse / hospitality | 80–200 kW | 60–150 kWh | Demand shaving + refrigeration backup |
| Manufacturing / logistics | 150–500 kW | 150–500 kWh | Peak-demand reduction + resilience |
