Three Phase String Inverter
Three phase string inverter is used in photovoltaic systems to convert the DC electricity into AC electricity then operates in homes and businesses. It can handle high voltage DC input from multiple solar panels. Then it utilizes advanced power electronics to manage the power flow. This ensures maximum energy conversion efficiency.
- High voltage DC input – handles 400 to 1000 volts from multiple solar panels.
- Uses advanced power electronics like MPPT.
- Can be scaled to meet the needs of small/large PV systems.
- Perfect solution for both commercial and residential applications.
- Comes with user-friendly interface that provides real-time monitoring of the energy production.

Available Designs for Three Phase String Inverter
Here’s a breakdown of some available designs for 3-phase inverters and their features:
- Wall-Mounted: Ideal for installations where space is limited. Wall-mounted 3 phase inverters are compact and can be installed on a vertical surface. They are typically available in lower power ranges. Therefore, it is suitable for residential and small commercial solar power systems.
- Freestanding: This design is typically used for larger commercial and industrial solar power systems. Freestanding 3-phase inverters are larger in size and can handle higher power outputs than wall-mounted inverters. They are designed to be installed on a level surface.
- Outdoor 3-Phase Inverter: Perfect choice for installations where the inverter will be exposed to the elements. It is designed to be weather-resistant and can withstand exposure to rain, snow, and extreme temperatures.
- Modular: Popular design for large-scale solar power systems. It consist of multiple smaller inverters that can be combined to create a larger system. This design allows for easy scalability, as additional inverters can be added as needed to increase the system’s capacity.
- Hybrid: It combines the functionality of a 3-phase inverter with a battery storage system. This design can be used in off-grid or grid-tied systems – allow for energy storage to be used during times of low sunlight or high demand.
Finding the Perfect Inverter for Your Needs
It is an important decision that can impact the performance and efficiency of your system. Here are some key factors to consider when selecting an inverter for your application:
- Power output – should match the power output of your solar panels.
- Efficiency: Look for an inverter with high efficiency ratings.
- Compatibility: Ensure that the inverter you select is compatible with the other components of your solar power system, such as the solar panels, battery storage, and monitoring systems.
- Warranty: Look for an inverter with a warranty that covers at least 10 years.
