Maximising Corporate Renewables: Smart Inverters and Asset Financing

Among the main benefits of investing in renewable energy for SA businesses are load-shedding mitigation, cost savings on growing electricity bills, and public sentiment awareness. As companies struggle with shifting legislative or legal frameworks, inconsistent energy security, and changing climate conditions, climate risk and sustainability have emerged as critical pillars for many enterprises worldwide. In addition, there is a growing public desire for businesses to do more to protect the environment and fulfil their obligations to society as a whole.This is where inverter financing comes in.

The imperative to tackle climate risk and sustainability has resulted in a review of practices for numerous South African enterprises.

The growing interest of companies in the commercial, industrial, and agricultural sectors in renewable energy is emphasised in an analytical analysis by sustainability expert Mark Boshoff as a calculated action to counter the hazards related to load-shedding and climate change. The search for renewable alternatives is not only strategic but also necessary for long-term success and managing climate-related risks, especially for South Africa’s agriculture sector, which accounts for a sizeable portion of the country’s GDP and is severely impacted by environmental extremes.

In South Africa in particular, the industry, which employs 785 000 people and contributes 10% of all foreign exports, is already being negatively impacted by rising temperatures, flooding, and increasingly severe and frequent droughts. “Due to the ongoing energy crisis, the price of power is rising at an exponential rate as its supply grows less stable. In other words, mitigating climate risk is necessary for the agriculture sector to thrive.

The major benefits of businesses investing in renewable energy include;

  • Potential to offset surplus electricity to the grid, resulting in cost-reduction;
  • Mitigation of rising energy costs on cash flows and bottom lines;
  • Avoiding power interruptions, load-shedding and maintaining production;
  • Contributing to a positive impact on the environment and easing public pressure;
  • Benefitting from carbon credits and selling electricity to green energy companies

Smart Inverters

Smart inverters transform the alternating current (AC) required by business power systems from the direct current (DC) produced by solar panels. Because they facilitate improved grid stability and effective energy management, they are essential to renewable energy projects. These projects are made possible by asset financing, which supplies the required funds for investment without requiring hefty upfront expenditures. This financial approach is especially pertinent in South Africa, where businesses are turning more and more to renewable energy to offset unstable electricity prices. Businesses may maximise energy production, cut waste, and achieve sustainability goals by integrating smart inverters, which can be financed with asset financing.


The Role of Smart Inverters in Renewable Energy

Economic pressures compound the environmental challenges. Volatile energy prices and the increasing cost of traditional energy sources strain the operational budgets of agribusinesses. Moreover, the South African economy’s fluctuations, including currency volatility, impact the affordability of imports, including petroleum-based fuels and agricultural inputs. Agricultural solar financing can alleviate some of these economic pressures by providing agribusinesses with access to renewable energy solutions. By investing in solar energy through tailored financing options, farms and agribusinesses can lock in energy costs and reduce their exposure to volatile energy prices, leading to improved financial stability and predictability in operations.

How Smart Inverters Optimise Energy Production and Contribute To Grid Stability.

Traditional inverters are designed simply to convert energy; however, “smart inverters” go beyond this basic function. They come equipped with advanced features enabled by modern computing and communication technologies, which add several technological advantages and efficiencies.

One major advantage is the capability of smart inverters to engage in what’s referred to as “inverter financing” of electrical grids. This does not refer to financial transactions but is a metaphor for the ways in which smart inverters manage and supply power. By actively managing voltage and reactive power, smart inverters can respond to grid demands in real-time. This is akin to a financial investment in the grid’s health—hence the use of the term “financing.” The advantages of such smart technology include the ability to:

  1. React to Grid Needs: Smart inverters can detect and respond to issues such as voltage fluctuations and phase imbalances. This quick response capability helps maintain the stability and quality of the power in the grid.

  2. Improve Reliability: By providing ancillary services like frequency regulation and voltage support, smart inverters can enhance grid reliability and reduce the likelihood of power outages.

  3. Enable Advanced Grid Functions: Smart inverters support advanced grid functionalities, including the integration of battery storage systems and the implementation of demand response programs, which are essential for grid stability as renewable energy sources become more prevalent.

  4. Maximise Energy Production: With “inverter financing” of energy flows, smart inverters can adjust their output based on the needs of the grid and the availability of renewable energy, leading to more efficient energy production.

  5. Facilitate Grid Integration: As renewable energy sources like solar and wind power have variable outputs, smart inverters help integrate them smoothly into the electrical grid without causing instability.

When it comes to optimising energy production and contributing to grid stability, smart inverters are at the forefront:

  • Predictive Analytics and Control: They use predictive analytics to anticipate energy production patterns and adjust the inverter’s operation accordingly. This ensures that they are operating at optimal efficiency and contributing the most energy to the grid when it is needed most.

  • Voltage Regulation: They help in mitigating voltage-related issues that can arise from the intermittent nature of renewable energy sources. By quickly adjusting the voltage output, smart inverters can prevent over-voltages that might otherwise lead to the disconnection of renewable generators.

  • Frequency Regulation: Frequency on the electrical grid needs to be kept within narrow boundaries. Smart inverters can provide rapid frequency regulation services, reacting to frequency deviations by either absorbing excess energy or injecting additional energy into the grid.

  • Phase Balancing: In three-phase power systems, phase imbalances can occur due to uneven loads. Smart inverters can balance these phases, thus stabilising the grid.

  • Islanding and Resiliency: Smart inverters can detect when the grid goes down (in what’s called “islanding”) and can disconnect the renewable energy source to prevent feeding power into a downed grid (which can be dangerous for utility workers). Conversely, if designed with grid resiliency in mind, smart inverters can also enable a local microgrid to keep running, providing power despite broader grid outages.

  • Communication and Coordination: They often include communication capabilities that allow for coordination between various distributed energy resources, utility control centres, and energy management systems. This interoperability is key to smart grid functionality.

Through these mechanisms, smart inverters serve as a critical tool for “financing” grid stability and optimizing energy production, leveraging their technological sophistication to enable a more robust and responsive power system. As the adoption of renewable energy grows, the role of smart inverters and their advanced functionalities will become increasingly important in ensuring the efficient and stable operation of the electrical grid.
