A number of photovoltaic executives told reporters that "efficient components + tracking bracket + inverter" is a cheap Internet access device has become the industry consensus.

With the support of intelligent, AI+ and other high-tech technologies, there are more possibilities for high-power components to cooperate with supports, inverters and other industrial chain links.

In the power frequency inverter circuit, #1kw solar hybrid inverter the three-phase AC input of the main circuit passes through the commutation inductance, is connected to the rectifier composed of three SCR bridge arms, and then is converted into a DC voltage, and the output DC voltage is adjusted by controlling the conduction angle of the rectifier bridge SCR. value. #inverter 24v Since the SCR is a semi-controlled device, the control system can only control the turn-on point. Once the SCR is turned on, even if the gate drive is cancelled, it cannot be turned off. #inverter off grid It can only be turned off naturally after its current is zero, so its turn-on and turn-off All are based on a power frequency cycle, and there is no high-frequency turn-on and turn-off control. Since the SCR rectifier is a step-down rectifier, the AC voltage of the DC bus voltage output by the inverter is lower than the input AC voltage. In order to obtain a constant 220V voltage for the output phase voltage, a step-up isolation transformer must be added to the inverter output.
