Installing Grid Tied String Inverters
What are Grid Tied String Inverters?
Solar inverters are essential components in the utilisation of solar energy for household appliances. As solar panels generate direct current (DC) which cannot be used by common household items, the energy source requires converting into alternate current (AC), which is completed by an inverter. No solar panel system can fully operate without a solar inverter.
Grid tied inverters combine more than one inverter in a series, therefore allowing for an increase in voltage without affecting output power. This ensures that more energy can be converted safely and effectively without overpowering any components that are running on the AC. If more energy is produced than can be used, then it is effectively stored in reserve by turning the meter backwards, allowing homeowners to use more energy if output ever requires more than supply. Because of this efficiency, grid tied string inverters are very popular with home and business owners who require cost effective energy solutions.
The three main types of grid tied inverters are micro inverters, string inverters and central inverters.
Why should I use Grid Tied String Inverters?
Grid Tied String Inverters are the most common inverters used in homes and commercial buildings. Any home or small business owner running a solar PV system is likely to require a grid tied string inverter for their system – as it is the most suitable for small to average sized solar PV systems. More than one string inverter can be used on one solar PV system if necessary, dependent on the size of the system.
When purchasing grid tied string inverters, it’s important to ensure they have a high IP rating. IP refers to the inverter’s Ingress Protection rating. This is based on the inverter’s ability to prevent dust, water and other foreign objects from gaining access to the electrical components within. The quality and location of the seals and ventilation on the grid tied string inverter will affect its rating and ability to stop weather and objects from damaging the electrical components within. An IP rating of around 60 is considered sufficient protection.
