Definition:


Photovoltaic inverter (PV inverter or solar inverter) An inverter that converts the variable DC voltage generated by photovoltaic (PV) solar panels into mains frequency alternating current (AC), which can be fed back to a commercial transmission system or used by an off-grid power grid. Photovoltaic inverter is one of the important system balance (BOS) in photovoltaic array system, and can be used with general AC power supply equipment.

Photovoltaic inverters convert power on a single photovoltaic (PV) panel, which is typically rated at 400W, and up to 1.5KW for multiple PV panels. Photovoltaic inverters are usually based on a two-stage power conversion. First, a direct-current DC stage or booster circuit converts a variable DC voltage to a fixed DC voltage (typically 40 V-60 V). At the same time, the maximum power point tracking technology can maximize the energy obtained from the photovoltaic panel (usually FSW = 100 KHz). The variable DC voltage is first converted to a fixed DC voltage (usually 40 V- 60 V) in the direct current DC phase or booster circuit. At the same time, the maximum power point tracking technology ensures that the maximum current is extracted from the photovoltaic panel. Secondly, in the DC AC stage, the inverter stage converts the DC power supply into a 1Φ AC power supply compatible with the grid. In contrast to string inverters, micro inverters can connect one, two or four PV panels and MPPT track each PV module separately.

Through the use of high-density device structure design and advanced ultra-thin chip processing technology, the company introduced a new generation of IGBT products, which significantly reduce device saturation voltage drop and turn-off loss by optimizing carrier injection efficiency and carrier distribution, thereby reducing device power consumption and improving system efficiency.
