SUNNY CENTRAL 250-US / 500-US

Product catalog summary

Overview: The Sunny Central 250-US and 500-US solar inverters are designed for commercial projects in North America. They feature an integrated transformer for direct low-voltage grid connection and are suitable for outdoor installation due to their weather-resistant enclosure and OptiCool™ temperature management system. These inverters boast a CEC efficiency of 97%.

Certifications: The inverters are UL 1741 and IEEE-1547 compliant, ensuring they meet North American safety and performance standards.

Key Features:

Integrated isolation transformer
AC/DC disconnect unit
Optional combiner boxes
Sunny Central String-Monitor-US for enhanced monitoring
Remote maintenance via integrated data logger accessible through RS485, Ethernet, or OPC interfaces

Efficiency: Both models offer a maximum efficiency of approximately 97.5% and a CEC efficiency of 97%.

Technical Specifications:

Input Data: Max DC power is 285 kWp for the 250-US and 570 kWp for the 500-US. MPP voltage range is 330 V – 600 V, with a max DC voltage of 600 V.
Output Data: Nominal AC power is 250 kVA for the 250-US and 500 kVA for the 500-US. Both models operate at an AC grid frequency of 60 Hz and have a power factor greater than 0.99.
Environmental Conditions: Operating temperature range is from -25 °C to +50 °C. The units are rated for NEMA 3R protection, suitable for both indoor and outdoor installations.
Dimensions and Weight: The 250-US model weighs less than 1900 kg, while the 500-US model weighs less than 3250 kg.

Communication and Monitoring: The inverters support Modbus/TCP communication protocols and plant monitoring via Sunny Portal. They include RS485 interfaces for SSM-US connection.
