The inverter is a critical component of the solar panel system – its ‘brain’. The inverter converts the DC electricity produced by the solar panels into AC electricity that can be used in your home or business or sold to the utility. It also must include key safety features required by the Ceylon Electricity Board (CEB) and the Lanka Electricity Company (Private) Limited (LECO).
Here are the steps to select the best-suited inverter for your solar panel system:
A) Ensure the capacity is suitable for the needs of your home or business.
Your energy needs will depend on factors such as your home or business size, the number of occupants, and the appliances you use. The inverter should have a capacity that matches your energy needs. Oversizing the inverter is not recommended as underloaded inverters generate more harmonics, resulting in poor-quality electricity output.
B) Choose between string inverters and micro-inverters based on your system size and shading issues.
String inverters are the most common type and are suitable for systems with minimal shading issues. Shading issues refer to the obstruction or partial covering of solar panels by nearby objects, such as trees, buildings, or other structures, which can result in reduced energy production. Micro-inverters are ideal for systems with partial shading problems or when you have a multipaned roof, as they guide each panel to generate independently (this is called MPPT tracking).
C) Check the certifications and features of the inverter, such as efficiency, voltage range, and monitoring capabilities.
- The inverter should have certifications from recognized bodies such as UL, TUV, or IEC.
- The inverter’s efficiency will determine how much electricity is lost during conversion.
- The voltage range should match the DC voltage of your solar panels
- The inverter should have monitoring capabilities to track the system’s performance. Also, if the inverter is placed outside, the IP rating of the inverter has to be considered.
D) Select a reputable brand that offers warranties and after-sales service.
Choose a brand that has a proven track record of reliability and offers warranties and after-sales service to ensure the longevity and performance of your solar panel system.
Hayleys Solar Inverters offer high-quality, efficient, and reliable solutions for all solar power systems. Designed to cater to a wide range of commercial, industrial, and residential applications, these inverters can handle capacities ranging from 1kW to 100kW. Hayleys Solar inverter brands use multiple MPPT tracking technology, allowing maximum energy harvest from your solar panels. These inverters are backed by a 10-year warranty, giving you peace of mind and protecting your investment.
Notably, the most common cause of inverter failure is grid surges and lightning strikes, which are not covered under the manufacturer’s warranty. We strongly recommend that you insure your inverter and the entire solar panel system as a precaution to enjoy added protection and peace of mind.
