Cutting-Edge Technology for Maximized Efficiency
Advanced Three-Level Technology
The SG6600/8800UD-MV-20 utilizes advanced three-level technology, which is at the forefront of inverter design. This technology enhances the inverter’s ability to convert DC from solar panels into AC with minimal losses, achieving a maximum efficiency of an impressive 99%. Here’s how this benefits large-scale solar installations:
– Reduced Energy Loss: Minimizing conversion losses means more of the solar energy captured is converted into usable power, enhancing overall system efficiency.
– Increased ROI: Higher efficiency translates directly to increased return on investment, as more of the generated energy is sold or utilized.
DC 1500V System
A higher system voltage level of 1500V DC allows for several key advantages:
– Lower System Costs: With higher voltage, the current is lower for the same power, which means thinner and less expensive wiring can be used.
– Reduced Energy Loss: Lower currents also reduce energy loss over cable runs, making the system more efficient over larger distances typically found in utility-scale installations.
Integrated System Design
Integrated MV Transformer, Switchgear, and LV Auxiliary Power Supply
The integration of critical components such as the MV transformer and switchgear within the inverter itself simplifies the overall design and installation of solar projects:
– Compact Design: Reduces the physical footprint needed for inverter systems, crucial for sites with space limitations.
– Simplified Installation: Minimizes the complexity of onsite installations and reduces labor and installation costs.
