HE30807T1911SC7M, also known as HE single-phase PV solar inverter or photovoltaic power generation inverter, utilizes intelligent maximum power algorithm to reach the maximum efficiency conversion ratio and standby performance, and is widely used in household solar PV generation system and industrial and commercial solar PV generation system. Working principle of HE30807T1911SC7M solar inverter is as follows:

The working principle of HE30807T1911SC7M is based on the concept of three-dimensional vector space. It uses three-dimensional space vector (SVC) to decompose the input voltage and current in photovoltaic array. After decomposition, the three components of SVC are shown in the form of vectors. According to the law of vector superposition, the three components of SVC need to be added together to get the maximum conversion efficiency. The current sensed by the PV inverter will be compared with the maximum power point from the vector modulator. Based on the comparison result and power loss due to switching, the vector modulator will control the current vector with maximum power output every sampling cycle.

In addition to adjusting the current to the maximum power point, vector modulators will also adjust the reactive load and active load conditions depending on the power factor and other requirement of the photovoltaic system. The vector modulators will release the current control signal for each switching cycle to the switching components of the inverter, such as the IGBT and gate driver, this will cause the switches turn on and off on the predefined patterns. After passing through the power switches, the voltages and currents are converted into AC output. The output voltage can be adjusted with respect to the battery voltage level for better protection of the battery itself.

The HE30807T1911SC7M is widely used in household solar PV generation system and industrial and commercial solar PV generation system. It is designed for various solar power applications in extreme environments such as extreme temperature, shock and vibration. It can effectively convert the direct current output of the photovoltaic module into alternating current, and connect it to the grid or local AC loads. It is extremely reliable and easy to use.

In conclusion, the HE30807T1911SC7M solar inverter uses intelligent maximum power algorithm to reach the maximum efficiency conversion ratio and standby performance which can be used in both household and industrial and commercial solar PV generation system. It uses three-dimensional space vector SVC to decompose the input voltage and current in photovoltaic array, and adopts vector modulators to compare and adjust the vector of the current with the maximum power point from the vector modulator, thus achieving the maximum conversion efficiency. It is designed for various solar power applications in extreme environments and is extremely reliable and easy to use.
