Features of hybrid ESS system
- Hybrid ESS system with uninterruptible functionality added to existing ESS system
→ Demand management operation + critical load uninterruptible power supply
| Evaluation item | Load type | General ESS | Hybrid ESS |
In case of a short-term power outage | Essential load | Uninterruptible | Uninterruptible |
| Semi-essential load | Power outage | Uninterruptible (emergency power supply mode) |
- Excellent power supply quality
- After the load is supplied, the remaining electricity is stored in the storage battery.
- Battery discharge when solar power generation is impossible or when electricity consumption is at peak.
- Case in Japan
- Simultaneously applied to commercial, industrial, and home use to solve power shortage
Operation mode
Demand management operation
- Reduces electricity cost by charging storage batteries during light load times when the power rate is low and discharging during maximum load times or peak load.
- Supplies power to the grid and load side during the peak load and grid peak load.
- High-quality, stable power supply to the load side at all times
Operation during grid outages
Disconnects the grid discharge circuit and supplies uninterrupted power to essential load.
