How to select best suited inverter for your solar power system

The inverter serves as a crucial element within the Solar PV System system, often referred to as its ‘brain.’ Its primary function involves converting the DC electricity generated by Solar PV Systems into AC electricity suitable for home or business use, or for sale to utility providers. Additionally, the inverter must incorporate essential safety features mandated by regulatory bodies such as the Ceylon Electricity Board (CEB) and the Lanka Electricity Company (Private) Limited (LECO).

To choose the most appropriate inverter for your Solar PV System system, follow these steps:

• Ensure the inverter’s capacity aligns with the energy needs of your home or business. This determination depends on factors like property size, occupancy, and the types of appliances utilized. It’s crucial to select an inverter with a capacity matching your energy requirements, avoiding oversizing, which can lead to increased harmonics and suboptimal electricity output.
• Choose between string inverters and micro-inverters based on your system size and shading concerns. String inverters, suitable for systems with minimal shading, are the more prevalent type. Shading issues, caused by obstacles like trees or buildings, can diminish energy production. Micro-inverters are preferable for systems facing partial shading challenges or those with multipaned roofs, enabling independent generation for each panel through MPPT tracking.
• Assess the certifications and features of the inverter, including efficiency, voltage range, and monitoring capabilities. The inverter should hold certifications from recognized bodies such as UL, TUV, or IEC. Efficiency determines the extent of electricity loss during conversion, and the voltage range should align with the DC voltage of your Solar PV Systems. Monitoring capabilities are essential for tracking system performance, with additional consideration given to the inverter’s IP rating if installed outdoors.
• Choose a reputable brand offering warranties and after-sales service. Opt for a brand with a proven reliability record, providing warranties and after-sales support to ensure the longevity and optimal performance of your Solar PV System system.
