BACKGROUND

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 daily , President Cyril Ramaphosa declared a national “ state of disaster ” to address the power crisis .

Under the power supply constraints , residents ’ demand for reliable and stable power supply drives South African household photovoltaic + energy storage to become one of the best choices for local energy utilisation . 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 .

Solis launched the Solis S6 Advanced Power Hybrid Inverter on Apr 25 , 2023 , to inject new energy into South African residential and commercial power , releasing more people from the effects of power outages . Introducing the latest product brought about a strong response in the local market . This Solis seminar will comprehensively overview 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 .

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 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

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 6-8 hours . For those types of outages , the battery bank needs to be large . 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 charge your batteries when the grid is active quickly 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 per cent . 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 maximising the use of photovoltaic energy , making photovoltaic power meet all-weather demand and improving the power generation and utilisation per unit area .

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 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 of < 4ms , achieving truly seamless switching and allowing users to break free from the troubles of power interruptions completely . 3 . Stronger load capacity - Many appliances with considerable 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 ,

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 three to 11 per cent .

IV . INTELLIGENT AND FLEXIBLE FUNCTIONAL DESIGN - EASIER APPLICATION

1 . Six-stage intelligent charging and discharging settings - The Solis S6 Advanced Power Hybrid Inverter provides 6-stage customisable charging and discharging time settings , optimising household electricity usage habits through reasonable charging and discharging settings , thereby reducing electricity expenses .
