Description

Key Features

1. High Charging/Discharging Current:
   • The Deye SUN series supports a maximum charging and discharging current of 135A. This high current capacity ensures rapid energy storage and retrieval, making the system highly responsive to energy demand peaks.
2. Compatibility with Diesel Generators:
   • These inverters support the storage of energy from diesel generators, providing versatility and additional backup power capabilities, especially useful in areas with unreliable grid supply.
3. Scalable Parallel Operation:
   • Up to 10 units can operate in parallel both in on-grid and off-grid modes. This scalability allows for both small-scale and large-scale energy requirements to be met efficiently, making it ideal for expanding energy systems.
4. AC Coupling for Retrofit:
   • The inverters can easily integrate into existing solar systems through AC coupling, offering a cost-effective route to upgrade current installations for enhanced performance and energy storage.
5. Time-based Battery Management:
   • Supports six time periods for battery charging and discharging, allowing users to optimize energy storage based on consumption patterns and electricity tariffs. This feature significantly enhances the cost-effectiveness of the energy system.
6. Low Voltage Battery with Isolation:
   • Operating with a 48V low voltage battery and transformer isolation design, the inverter ensures safe and efficient energy storage, reducing the risk of electrical hazards.
7. Unbalanced Output Capability:
   • Each phase can handle a 100% unbalanced output with a maximum output of up to 50% of the rated power for each phase. This flexibility supports varied load requirements without efficiency loss.
