Solis to Showcase Cutting-Edge Energy Solutions at REI 2025, Celebrating 20 Years of Innovation

Key Features of the S6-EH3P(75-125)K Hybrid Inverter:

 1.  Super Strong Photovoltaic Integration, Accelerating Investment Returns

•  2x Ultra-high Photovoltaic Capacity Ratio: The system supports photovoltaic power generation up to twice the rated capacity, with 10 MPPTs to significantly improve generation efficiency. It supports 21A high-current modules, compatible with future technologies. More power generation during the day and faster charging times, especially for energy-intensive facilities such as hotels and hospitals. This enables the "full charge during the day, sufficient use at night" model, significantly shortening the investment payback period.

2. Top Off-grid Performance, Ensuring Zero Interruption for Critical Operations

• 2x Off-grid Overload Capacity: Industry-leading instantaneous overload capability, easily starting high-power inductive loads such as air conditioners and elevators.
• <10ms Seamless Switching: Fast grid-off/grid-on switching within milliseconds, twice as fast as traditional systems. This ensures sensitive equipment and continuous production processes remain uninterrupted during grid instability, providing power protection similar to an "online UPS" system. This ensures uninterrupted operations for factories, malls, and critical data during grid failures.

• High Protection Rating IP66: Supports direct outdoor installation, ideal for outdoor environments. The higher protection rating ensures better equipment protection and reliability. This eliminates the need for indoor storage space for the energy storage system, making site selection more flexible and enhancing lifecycle reliability while reducing the risk of failures.

• Larger Single-Channel MPPT Current – Solis inverters support a maximum single-channel MPPT current of 80A, allowing for the use of higher power solar modules and minimising DC-side power limitations, which enhances system flexibility and efficiency.
• Superior High-Temperature Output Capability – Solis inverters maintain their rated DC voltage output even at 35°C without derating. This ensures stable performance in high-temperature environments, effectively reducing the impact of temperature on efficiency and ensuring reliable operation in more demanding conditions.

• AFCI with RSD: Solis integrates AFCI functionality with Rapid Shutdown (RSD), ensuring immediate disconnection when an AFCI fault is detected. This provides enhanced safety for commercial and industrial PV systems, meeting UL 1699B and IEC 63027 standards for arc protection and quick shutdown.
• Electronic DC Switch: Equipped with advanced electronic switches, the inverter automatically disconnects power in case of DC reverse polarity or short-circuit faults, offering superior durability and protection compared to mechanical switches.
• DC and AC Terminal High-Temperature Detection: The inverter continuously monitors terminal temperatures and automatically shuts down with an alarm if temperatures exceed safe levels, minimising risks associated with abnormal connections.
