Ensuring Energy Security in the Pursuit of Sustainability: Introducing the Solis 50kW Hybrid PV Inverter
12 Apr 2024

As the global community increasingly commits to the principles of sustainability, with a focus on the economy, society, and the environment, the crucial challenge now lies in ensuring the continuous availability of energy at affordable prices to support these principles. At the heart of this endeavour is the concept of energy security.

Energy security, defined as the uninterrupted availability of energy sources at an affordable price, encompasses various dimensions crucial for sustaining economic, social, and environmental well-being. Long-term energy security involves making timely investments to supply energy in harmony with economic development and environmental imperatives. Conversely, short-term energy security focuses on the ability of the energy system to respond swiftly to sudden changes in supply-demand dynamics (IEA, 2023).

One of the critical issues undermining energy security, particularly in developing nations, is the prevalence of power outages. These disruptions underscore the urgent need to accelerate the adoption of energy storage systems to enhance resilience and reliability.

Introducing the S6-EH3P(29.9-50)K-H, a groundbreaking hybrid PV inverter meticulously engineered for commercial and industrial applications. Chief features of a hybrid inverter comprise its ability to simultaneously connect to both solar panels and energy storage batteries. It’s like getting two inverters for the price of one.

Principal advantages of the S6-EH3P(29.9-50)K-H include:

1.At the solar panel input: there are four Maximum Power Point Tracking (MPPT) channels, allowing for the connection of solar panels facing different directions. Each MPPT channel can handle a current of up to 20A, making it compatible with mainstream high-power solar panels of 700W+. With the same roof area, this setup can increase solar power generation by up to 16%.

2.When it comes to battery input: this inverter can quickly charge one kilowatt hour in almost one minute, with a maximum charge/discharge current of 140A. This makes it suitable for energy storage systems based on 280Ah battery cells with a 2-hour capacity.

3.On the AC output side: it provides a continuous AC power of 50kW and supports a short-term overload of up to 1.6 times. This means that even during power outages or in off-grid areas which are common in South Africa and the rest of sub-Saharan Africa, equipment requiring a starting power of up to 80kW can still be restarted and operated normally.  Seamlessly integrating with diesel generators, this innovative solution ensures uninterrupted power supply even during peak loadshedding hours.

The S6-EH3P(29.9-50)K-H offers a plethora of benefits through its advanced energy management capabilities.This hybrid inverter offers unmatched versatility and enables seamless integration into a host of environments. In high-power consumption scenarios, such as manufacturing facilities, it empowers self-sufficiency through the parallel connections of multiple inverters. This enables crucial functions like peak shaving, expanding factory capacity, and boosting production capabilities—all while trimming electricity costs.

Similarly, installers can leverage its flexibility by tailoring the choice of battery brand and adapting generators to meet specific energy backup and demand adjustment needs, creating resilient microgrid systems. By maximizing energy generation, optimizing storage and distribution, and minimizing operational costs, the S6-EH3P(29.9-50)K-H delivers substantial long-term value for several applications, emerging as the preferred choice for businesses seeking to maximize their energy investments.

As the global community navigates the complexities of sustainability, ensuring energy security emerges as a fundamental imperative – the S6-EH3P(29.9-50)K-H hybrid PV inverter stands as a testament to innovation in this realm, offering a comprehensive solution to bolster energy resilience, reliability, and efficiency, thereby facilitating the realization of sustainable development goals worldwide.
