inverter mppt controller 4kw

  An inverter is a device that converts direct current into alternating current.#4kw solar inverter hybride 220vac           Since solar cells and storage batteries are DC power sources and the load is an AC load, inverters are essential. 

  According to the operation mode, the inverter can be divided into independent operation inverter and grid-connected inverter. The stand-alone inverter is used in a stand-alone solar cell power generation system to supply power to independent loads. 

  Grid-connected inverters are used for grid-connected solar cell power generation systems. According to the output waveform, the inverter can be divided into square wave inverter and sine wave inverter. The square wave inverter has a simple circuit and low cost, but has a large harmonic component. It is generally used in systems with a few hundred watts or less and low harmonic requirements. Sine wave inverters are expensive, but can be applied to various loads.

  The photovoltaic cell array is connected with the load through a DC/DC circuit, and the maximum power tracking device continuously detects the current and voltage changes of the photovoltaic array, and adjusts the duty cycle of the PWM drive signal of the DC/DC converter according to the changes.

Characteristics of inverter

1. High conversion efficiency and fast start-up.

2. Good safety performance: The product has 5 protection functions: short circuit, overload, over/under voltage, and over temperature.

3. Good physical properties: The product adopts an all-aluminum shell, with good heat dissipation performance, hard oxidation treatment on the surface, good friction resistance, and resistance to extrusion or impact by a certain external force.

4, strong adaptability and stability with load.

Specification:490*340*170MM

Photovoltaic inverters use maximum power point tracking (MPPT) technology to extract the maximum possible power from solar panels. There is a complex relationship between solar irradiance, temperature and total resistance of solar cells, so the output efficiency will change nonlinearly, called current-voltage curve (I-V curve).
