products DESCRIPTIONPRODUCTS
Working Principle of the 15kW Three-Phase Solar Energy Storage System
●Solar Power Generation
High-efficiency 725W photovoltaic modules from Trina Solar convert sunlight into DC electricity during the daytime.
●DC Power Conversion
The DC power generated by the solar panels is sent to the hybrid inverter, which converts DC electricity into three-phase AC power for household or commercial loads.
●Power Supply Priority
The system prioritizes solar power to supply loads first, reducing dependence on grid electricity and lowering energy costs.
●Battery Charging & Energy Storage
When solar production exceeds consumption, the extra electricity charges the 30kWh lithium battery, storing energy for night-time use or cloudy days.
●Night-Time Power Supply
At night or during low sunlight, the system automatically discharges energy from the lithium battery to power connected appliances.
●Grid or Generator Backup
If the battery level becomes low, the system can automatically switch to grid power or a diesel generator to ensure continuous electricity supply.
●Smart Energy Management
The hybrid inverter intelligently manages solar generation, battery charging/discharging, and grid interaction to maximize energy efficiency and system reliability.
In simple terms:
Solar panels generate electricity → inverter powers loads → extra energy charges the battery → battery supplies power when solar energy is insufficient → grid or generator acts as backup. ⚡🌞

FAQ
1. What appliances can a 15kW three-phase solar system run?
A 15kW system can power heavy loads such as air conditioners, water pumps, refrigeration systems, lighting, office equipment, and small industrial machines simultaneously.
2. How much electricity can this solar system generate daily?
Depending on sunlight conditions, a 15kW system typically produces 60–90 kWh of electricity per day, enough for large homes or small businesses.
3. Is a 30kWh lithium battery enough for backup power?
Yes. A 30kWh lithium battery can usually support household loads overnight or provide several hours of backup power for commercial applications.
4. Why choose 725W high-power solar panels?
High-power modules from Trina Solar reduce installation space, improve system efficiency, and lower BOS (Balance of System) costs.
5. Can this system work during grid outages?
Yes. The hybrid inverter automatically switches to battery power during power outages, ensuring uninterrupted electricity supply.
6. Can the battery capacity be expanded in the future?
Yes. The system design supports scalable battery expansion, allowing users to increase storage capacity up to 45kWh or higher.
7. What components are included in the complete solar system kit?
The complete solution includes solar panels, hybrid inverter, lithium battery, mounting structures, DC/AC cables, protection devices, monitoring system, and installation accessories.
