Battery storage sized for commercial demand
Commercial electricity tariffs include peak demand charges that a battery can significantly reduce. By storing energy during off-peak periods and discharging during demand peaks, a well-configured battery system can cut your overall electricity bill beyond what solar alone can achieve.
Our SAA-accredited Master Electricians assess your load profile and tariff structure before recommending any battery. We design for your actual commercial demand — not a residential rule-of-thumb. All installation is carried out by our own licensed team with minimal disruption to your operations.
What Battery Storage Does
Commercial battery applications
Peak demand reduction
Discharge during your tariff peak window to reduce demand charges — often the largest component of a commercial electricity bill.
Solar self-consumption
Store excess solar generation and use it during evening trading hours rather than exporting at low feed-in rates.
Backup power
Keep critical loads — refrigeration, security, IT infrastructure — running during grid outages. Configured to your specific backup requirements.
Time-of-use arbitrage
Charge from the grid at off-peak rates, discharge during peak periods. Effective where time-of-use tariffs apply.
Scalable capacity
Sigenergy and ESY systems are modular — capacity can be increased as your energy needs grow, without replacing the system.
Out-of-hours installation
Installation scheduled outside trading hours to avoid any disruption to your business operations.
