Note: For those starred models, pure sine wave inverters are preferred.

The difference between the pure sine wave and the modified wave of the inverter is:

   1. The inverter mode is different. Pure sine wave inverters generally adopt PWM inversion, and some even add multi-step inverters. The structure is complicated, but the output waveform is good, and it is suitable for inductive and capacitive loads. Modified sine wave inverters generally use square wave inverters, and a few add stepped inverters. The structure is simple, but the output waveform is poor, which is not suitable for inductive and capacitive loads.

  2, the output filtering method is different. Pure sine wave inverters generally use multi-level LC filtering methods to obtain relatively pure sine waves. The modified wave inverter is generally single-stage LC filtering, and the output is similar to a trapezoidal wave.

The shopping elements of modified sine wave

  1, the purchase element of the inverter-power

Generally, the inverter of the corresponding power section is configured according to the requirements of the system. The power of the selected inverter should match the maximum power of the solar cell array. Generally, the rated output power of the photovoltaic inverter is selected to be about the same as the total input power. This can save costs.

  2, the purchase elements of the inverter-key technical indicators

  1) Choose a suitable input and output voltage range to ensure the best combination of products.

   2) The European efficiency of the inverter: its level will directly affect the design cost and power generation efficiency of the photovoltaic power generation system.

  3) The maximum power tracking function (MPPT) of the solar cell array and its efficiency.

  4) It should be noted that the selected inverter should have basic protection functions, such as over current/short circuit protection, over power protection, over temperature protection, lightning protection, islanding protection and other functions.

  5) Inverter output current waveform distortion rate (THD%) should be less than 4%.

  3, the purchase elements of the inverter-certification standards
