AC and DC Coupled Commercial Solar System for Farms: Maximizing Efficiency and Reducing Costs

At the Langhoek farm, located just outside George, our innovative commercial team implemented a solar energy system that is ideal for farms seeking to optimize their operational energy costs.

The system combines solar generation with AC-coupled and DC-coupled technologies, resulting in maximum efficiency and a sustainable energy source for the farm. As a result, the system is capable of reducing the impact of increasing electricity prices, and maximizing grid usage efficiency.

The AC-coupled side of the energy system features 81kVA grid-tied Fronius commercial inverters connected to a 103.74kWp PV array, providing a significant amount of solar energy for use on the farm.

On the other hand, the DC-coupled side of the system features 90kVA Victron commercial inverters/chargers connected to 66kWp PV array, adding to the overall energy output of the system. These inverters are used to charge the batteries and power essential energy distribution during load-shedding periods.

With 3 x 100/80 Freedom Won batteries providing 240kWh of usable energy and the system’s smart features optimizing grid usage during the most cost-effective hours, the solar array generates an average of 680kWh per day. This means significant reductions in daytime power costs, as well as energy for late afternoon and nighttime farm operations.

Moreover, by reducing the need for diesel generators, the AC and DC Coupled Commercial Solar System not only saves the farm money but also minimizes their carbon footprint. Plus, with the option for “Green Time” scheduled charging during off-peak Eskom tariffs, this solar energy system is not only environmentally friendly but also financially savvy.

So, whether you’re looking to cut costs, reduce emissions, or simply generate a sustainable energy source for your farm, the AC and DC Coupled Commercial Solar System is the perfect fit for you. Join the ranks of industry-leading farms and set an example for others to follow – all while maximizing your operations with the power of the sun!
