Three-phase inverter with 3 MPT

A three-phase inverter with 3 maximum power point tracking functions is a device specifically designed to optimize the efficiency of power conversion from multiple photovoltaic (PV) panels or arrays. In a solar photovoltaic power generation system, the main task of the inverter is to convert the direct current (DC) generated by the photovoltaic panel into alternating current (AC) so that it can be fed into the grid or used by local loads.

MPT (Maximum Power Point Tracking) technology

MPT technology is an algorithm that monitors the output of a photovoltaic array in real time and ensures that the photovoltaic array is always operating near its maximum power point by constantly adjusting the operating point. This helps maximize energy harvesting and maintains high efficiency even under partially occluded or uneven lighting conditions.

Features of three-phase inverter with 3 MPT

• Multiple input channels: This inverter has three independent input channels, each of which can be connected to a photovoltaic array. This means that the inverter can process solar power inputs from three different sources at the same time.

• Independent maximum power point tracking: Each channel has its own MPT controller that can independently track the maximum power point of its respective connected PV array. This makes it possible to better adapt to multiple PV arrays in different locations, different orientations or different shadow conditions, thereby improving the efficiency of the overall system.

• Three-phase output: The inverter outputs the converted alternating current to three-phase power, which is typically used in commercial or industrial-scale solar systems because three-phase power is better suited to applications with high power requirements than single-phase power.

• Greater flexibility: By allowing multiple PV arrays to be connected to the same inverter, system designers can more flexibly configure solar systems to suit different installation environments and needs.

• Enhanced reliability: Even if one PV array has problems or decreases in efficiency, the other arrays can continue to operate efficiently, thereby maintaining the overall performance of the system.

Application scenario

This type of inverter is usually suitable for large solar photovoltaic power generation systems, such as commercial buildings, industrial facilities, or utility-scale solar farms. These systems tend to cover large geographic areas and have multiple distributed PV arrays, so using inverters with multiple MPT can improve the efficiency and reliability of energy harvesting for the entire system.

Sum up

Three-phase inverters with 3 MPT provide an efficient, flexible and reliable solution for large-scale solar power systems by optimizing the energy conversion efficiency of multiple PV arrays. This technology is especially suitable for projects that want to maximize solar energy efficiency and face complex installation environments.
