What is a three-phase solar inverter and why is it needed?
If you want to save on electricity or make your home or business more energy-efficient, you should consider three-phase solar inverters. These are devices that convert direct current from solar panels into three-phase alternating current, which is used to power the electrical grid. They are especially relevant for large homes, businesses and commercial facilities where the load needs to be evenly distributed across three phases.
What are three-phase inverters?
There are several main types of inverters on the market, and each of them has its own characteristics:
- On-grid inverters are the best choice if you have a connection to the public electricity grid. They allow you to not only use solar energy for your own needs, but also sell excess energy back to the grid.
- Off-grid inverters are suitable for places where there is no centralized power supply. They work in conjunction with batteries, providing electricity even at night or in cloudy weather.
- Hybrid inverters – combine the advantages of the two previous types. They can work with both the grid and batteries, making them a versatile option.
Where are three-phase inverters used?
These devices are ideal for:
- Large houses – if you have a three-phase electrical network, such an inverter will help distribute the load evenly.
- Businesses and commercial facilities – offices, shopping malls, warehouses – can significantly reduce electricity costs.
- Industries – factories and businesses often use three-phase systems to power equipment.
- Agriculture – such inverters power pumps, irrigation systems, and lighting on farms.
How to choose a three-phase inverter?
To purchase the best option, pay attention to the following characteristics:
- Power – the inverter should meet your electricity consumption needs.
- The number of MPPT trackers – the more, the more efficiently the system will use solar energy.
- Efficiency (efficiency coefficient) - it is desirable that it be 96% or higher.
- Protection – it is important that the device has protection against overheating, voltage surges, and weather conditions.
- Warranty – choose models from trusted manufacturers that provide a 5-10 year warranty.
- Monitoring – modern inverters allow you to monitor operation via a smartphone or computer.
