Selecting the right inverter is crucial when it comes to renewable energy installations, especially in a country like South Africa, where electricity issues present unique challenges. With frequent power outages, surges and an unstable grid, the choice of inverter can mean the difference between prolonged reliability and premature failure. Probenergy, a leader in the field, emphasises an holistic approach, leveraging deep knowledge of South African conditions to provide solutions that are effective and sustainable.
“The decision between inverters can be compared to choosing between a Porsche and a VW,” says Probenergy expert Grant van Houten. “While both are fundamentally robust, and designed in the same factories by the same engineers, the real question is about the level of functionality you need and will use, and fitness for purpose.”
Probenergy partners with renowned brands such as TBB, Victron Energy, Growatt, Deye and SunSynk, each offering distinct advantages tailored to local needs. TBB, for instance, provides robust inverter solutions well-suited for hybrid systems, ensuring seamless energy management. Victron Energy, known for its premium quality, offers inverter/chargers that integrate well into backup systems, providing excellent reliability even at a higher price point.
Growatt stands out for its cost-effectiveness without compromising on quality, making it an attractive option for budget-conscious consumers who still demand performance. Meanwhile, Sunsynk and Deye’s hybrid inverters balance solar energy use with grid power well, optimising efficiency and savings.
Understanding inverter technology
High-frequency inverters, known for their compact size and efficiency, use high-frequency switching transistors. However, these inverters often falter under South Africa’s erratic power conditions, as they have a limited tolerance for power surges and high starting currents from equipment such as pumps and compressors.
In contrast, low-frequency transformers are equipped with an iron core that acts as a buffer, absorbing power surges and protecting both the inverter and connected appliances. This enhances their reliability, making them suitable for the volatile South African energy environment.
Taking an holistic approach
Probenergy delivers solutions that are precisely engineered to withstand the local environment. “By focusing on the right technology rather than brand prestige, we ensure our customers receive the best value and longevity from their renewable energy systems. Our approach considers every aspect of the system, from the capacity to handle inductive loads to the inverter’s ability to handle power surges,” says van Houten.
Van Houten says while some inverters may perform well in stable electricity environments overseas, the local conditions in South Africa are more challenging. “It’s important to invest in durable, long-term inverter solutions that can cope with the challenges posed by our unique power landscape to get the best return on investment.”
While budget and brand often influence decision-making, the key is to focus on the technology that meets your specific needs. “With Probenergy’s comprehensive understanding and commitment to excellence, South Africans can enjoy reliable power solutions tailored to their environment, ensuring peace of mind and sustainable energy use for years to come,” says Van Houten.
