Key features include modular design, compatibility with various battery brands, and compliance with NEMA 3R/IP54 standards. Specifications highlight wide DC voltage ranges, high efficiency, and robust safety features.

Sirius Series: The Sirius Series focuses on cabinet power conversion systems, offering models like the PWS1 and PWG2 series. These systems support flexible configurations, high efficiency, and extensive compatibility with different battery types. They are designed for both grid-tied and off-grid applications, with features like multi-string technology and global grid certification.

Specifications: Detailed technical specifications are provided for each model, covering aspects such as power ratings, voltage ranges, cooling systems, and communication protocols. The document also outlines safety and compliance standards, including UL9540 and other international certifications.

Application Diagrams: The document includes diagrams illustrating the application of energy storage systems (ESS) and power conversion systems (PCS) in various configurations, such as on-grid, off-grid, and hybrid setups.

Key Features: Across all series, the systems are designed for easy installation, maintenance, and scalability. They offer high efficiency, safety, and compatibility with a wide range of batteries and grid standards. Optional components like PV input and auto-switching devices enhance their versatility.

Specifications: The document outlines specifications for multiple models, including PWS1, PWG2, PDS1, and PBS1 series. Key parameters include AC and DC power ratings, voltage and current ranges, efficiency, cooling methods, noise levels, and environmental conditions such as operating temperature and humidity.

Features: The systems are designed with modularity, allowing for flexible configurations and scalability. They support high efficiency, with peak efficiencies reaching up to 99.5%. The systems are compatible with various battery types and include features like multi-string technology, MPPT functions, and grid-support capabilities.

Safety and Compatibility: The systems are equipped with safety features such as emergency power off (EPO), over-temperature protection, and fault indicators. They are certified to meet global standards, including IEEE, UL, CSA, and IEC certifications.

Installation and Configuration: The systems support both indoor and outdoor installations, with enclosures rated up to IP55/NEMA3R. They offer flexible grid connections and can operate in both grid-tied and off-grid modes. Communication protocols include Modbus TCP/IP, RS485, and CAN, facilitating integration with energy management systems.

Applications: The systems are suitable for a wide range of applications, including solar and storage hybrid systems, standalone battery storage, and grid-support functions. They are designed for use in both front-of-meter and behind-the-meter scenarios.

AC Parameters: The document outlines the nominal AC power ratings for different models (300kVA, 375kVA, 430kVA) with three-phase connections, overload capabilities, and voltage/frequency ranges. Total Harmonic Distortion (THDi) is maintained at ≤3%, and the power factor is adjustable between -1 and 1.

DC Bus and PV Side: The DC voltage range varies across models, with a maximum DC current of 474A/237A. The PV side supports a voltage range of 500V to 1500V with one or two PV inputs.

System Parameters: The systems boast a peak efficiency of 99%, with dimensions and weight specified for different configurations. They operate within a temperature range of -20°C to 60°C, with air cooling and IP65 enclosure ratings.

Communication and Compliance: Communication options include RS485, Ethernet, and CAN, supporting protocols like ModbusTCP/RTU and IEC standards. The systems comply with CE and UL certifications.

Modules and Features: Various modules such as the PWS2-30P-NA/EX, PDS1-45M, and PWD-100M are detailed, highlighting features like wide voltage ranges, high efficiency, modular design, and compatibility with different battery types. Safety features include over-voltage and over-current protection.

Applications: The document describes applications for energy storage systems (ESS) and power conversion systems (PCS), including on-grid, off-grid, and hybrid solutions. It emphasizes the flexibility and scalability of Sinexcel's solutions for different power needs.

Installation and Physical Specifications: Installation options include wall-mounted and floor-standing configurations, with specifications for cooling, noise levels, and environmental conditions.

DC-Coupled Solutions: These solutions are designed to work with diesel generators in remote areas, using DC-coupled photovoltaic (PV) farms to charge batteries. The diesel generator acts as a backup power source.

AC-Coupled & DC-Coupled Solutions with Generator: These systems can operate with both AC and DC-coupled PV farms. The Battery Energy Storage System (BESS) serves as a backup when the grid fails, with the diesel generator as a secondary backup.

AC-Coupled & DC-Coupled Solutions without Generator: In these configurations, the BESS provides backup power when the grid fails, but loads will shut down if both battery and solar energy are depleted.

Modular Power Conversion Systems: The document describes modular power conversion systems, including PCS and DCDC converters, which can be paralleled for increased capacity. Specific configurations include PWS1-500KTL/1725KTL and PDS1-400K/750K with multiple module options.

Technical Specifications: Systems utilize CAN, LAN, and RS485 for communication between devices and management systems. Details on power connections for Sinexcel devices are provided, emphasizing modularity and scalability. The document specifies the number of units that can be paralleled in both off-grid and on-grid projects, with limitations based on the presence of a single transformer on the AC side.

Recommendations: The document suggests using external EMS to command power conversion systems to switch to external AC sources when batteries are depleted, ensuring continuous power supply.
