Our Solution
This system adopts a 12kW hybrid inverter working with three 15kWh wall-mounted LiFePO4 batteries. 45kWh total energy storage provides sufficient energy storage capacity. The hybrid inverter supports solar charging, grid charging and automatic backup switching when grid fails.
- 12kW Hybrid Solar Inverter with WiFi monitoring
- 3 pcs 15kWh wall mount LiFePO4 battery, 45kWh total
- Rooftop PV modules, PV combiner & protection devices
- AC distribution box, communication cables and accessories
Installation & Site Condition
The 12kW hybrid inverter and 3 units of 15kWh wall batteries are mounted on the wall inside the utility room. We reserved enough ventilation gap for heat dissipation. All wiring, earthing and protection components follow Cambodia local electrical safety standards. The battery pack supports mobile APP remote monitoring.
Project Benefits
Automatic Blackout Backup
Instant switch to backup power when grid cuts off, protect refrigerator, lights and essential loads.
Cut Down Monthly Power Bills
Maximize solar self-consumption, reduce reliance on expensive utility grid power in Cambodia.
Safe LiFePO4 Battery with Smart BMS
Built-in smart BMS protects over-charge, over-discharge and overheating, remote APP monitoring.
Expected System Performance
This home storage system increases solar self-consumption rate and provides backup power for lights, refrigerator and essential loads during power cuts. Users can monitor battery status remotely via mobile APP.
FAQ
How long can a 15kWh home battery back up a house?
It can run essential loads like fridge, lighting for around 10–12 hours, depends on power consumption of connected appliances.
Is wall-mounted LiFePO4 battery safe for residential installation?
LiFePO4 chemistry is safer than ordinary lithium-ion. Built-in smart BMS protects over-charge, over-discharge and overheating.
