Solis Seminar 54: Solis S6 Advanced Power Hybrid Inverter, bring more uninterrupted power to your family

 - Power shortage has become a long-term issue in South Africa. There were 205 consecutive days of power outages here in 2022, and this has lasted every day since the beginning of 2023. The increasingly severe power shortage has seriously affected people's daily lives as well as the development of the socio-economy. As South Africa experiences power outages for up to 10 hours a day, President Cyril Ramaphosa declared a national "state of disaster" on Thursday to address the power crisis. Under the power supply constraints, the demand for reliable and stable power supply from residents drives South African household photovoltaic + energy storage to become one of the best choices for local energy utilization. According to the Council for Energy Storage (CES) forecast, South Africa's cumulative installed capacity for ground energy storage is expected to reach 14.8 GWh by 2030.

In this context, Solis launched the Solis S6 Advanced Power Hybrid Inverter on April 25, 2023, with the goal of injecting new energy into South African residential and commercial power and releasing more people from the effects of power outages. The introduction of the new product brought about a strong response in the local market. This Solis seminar will provide a comprehensive overview of the new product's features.

I. About the Solis S6 Advanced Power Hybrid Inverter

The Solis S6 Advanced Power Hybrid Inverter is specifically designed for residential and commercial photovoltaic energy storage systems, with a maximum power of 48kW and support for multiple parallel single-phase or three-phase systems. It has a UPS-level switching time of 4ms with a 10s surge power overload. It supports connection with generators of various input methods and has a variety of intelligent protection functions to ensure the safety and reliability of household power supply. The recent introduction of this new product brought about a strong response in the local market.

II. Efficient and Reliable Energy Security - Breaking Free from Power Outages

Based on the residential green power solution of the Solis S6 Advanced Power Hybrid Inverter, the primary goal is to provide customers with a reliable and independent energy supply to reduce electricity expenses and ensure the availability of electricity use. During the day when photovoltaic power generation exceeds load demand, it first supplies power to local loads while charging the battery; if there is excess power, it can be sold to the main power grid; at night, the battery pack discharges to supply load demand; when the power grid is interrupted, the system can independently supply power to household appliances for an extended period.

1. Compatibility with various generators - In areas with frequent power interruptions, using a generator as a backup power source is a common and necessary method. The Solis S6 Advanced Power Hybrid Inverter can work in conjunction with a diesel generator and provide various diesel generator connection options. In addition to a traditional grid connection and Automatic Transfer Switch (ATS) conversion connection, the product also has an independent generator access port. Users can supply power to the load by connecting the generator to the inverter without changing the existing wiring. It can also send control signals to automatically start or stop the diesel generator as needed, avoiding diesel waste and long-term diesel engine noise.

2. Automatic switching – During normal operation, if the power is suddenly interrupted, the backup power equipment will provide a smooth and uninterrupted power supply to the load, ensuring that the load work is not affected. The Solis S6 Advanced Power Hybrid Inverter can provide UPS-level switching with a switching time < 4ms, achieving truly seamless switching, allowing users to completely break free from the troubles of power interruptions.

3. Stronger load capacity - Furthermore, many appliances with large instantaneous start-up power require more abundant power when starting in daily life. Without surge capabilities, this will affect the power supply voltage and cause some sensitive electrical appliances, such as TVs and computers, to malfunction. The backup output capacity of the Solis S6 Advanced Power Hybrid Inverter has been increased to twice the rated power and lasts for 10 seconds, which can meet the working requirements of all types of household loads.

III. Excellent Electrical Performance - 24-Hour Enjoyment of Sunlight

1. Faster charging and discharging speed - Outages can last up to 6-8 hours and for those type of outages the battery bank needs to be large. In order for those batteries to be full, the inverter technology has to follow. The charging and discharging current of the product can reach 190 Amps, which enables you to quickly charge your batteries when the grid is active or the PV production is high. This will quickly prepare the user for the next outage and ensure the batteries can last throughout the whole period.

2. Sufficient DC/AC ratio— The maximum DC ratio of the Solis S6 Advanced Power Hybrid Inverter reaches 160%. By introducing the energy storage system, the photovoltaic energy exceeding the inverter's rated output power can be stored in the battery instead of being wasted, thereby maximizing the use of photovoltaic energy, making photovoltaic power meet all-weather demand, and improving the power generation and utilization per unit area.

3. Larger DC input current - The input current of the Solis S6 Advanced Power Hybrid Inverter has been increased to 16A, making it more suitable for systems designed with high-efficiency, high-power photovoltaic modules, such as 550W or even 600W photovoltaic modules. Under a limited installation area, the capacity can be increased by 3% to 11%.

2. Single-phase/three-phase flexible grid connection - The Solis S6 Advanced Power Hybrid Inverter supports up to 6 devices in parallel for system expansion, forming a maximum 48kW hybrid power network while supplying power to three-phase and single-phase loads. When you need to build small and medium-sized commercial energy storage systems, this product enables it with its flexibility.
