TG series single phase pure sine wave hybrid solar power inverter 1.5kw -6kw

The small off-grid photovoltaic power generation system consists of photovoltaic arrays, battery packs, photovoltaic controllers, photovoltaic inverters, and AC and DC loads. During the day, the photovoltaic array converts solar energy into electrical energy, and under the control of the photovoltaic controller, provides electrical energy for the AC and DC loads and charges the battery; at night, the electricity stored in the battery supplies power to the AC and DC loads through the photovoltaic controller.

The photovoltaic inverter converts the direct current from the photovoltaic array or the battery into alternating current, which is the core equipment of the entire photovoltaic power generation system. The inverter structure consists of input circuit, inverter circuit, output filter circuit, control circuit, protection circuit and auxiliary power supply.

The input circuit shapes and filters the DC power from the photovoltaic array or battery. The inverters of small off-grid photovoltaic systems often use single-phase inverters. The inverter circuit converts the DC power into single-phase AC power. If open-loop control is used, the output There is no need to feed back to the control circuit, and if closed-loop control is used, the output quantity is also fed back to the control circuit. The function of the control circuit is to generate and adjust a series of control pulses as required to control the on and off of the inverter switch tube, so as to cooperate with the inverter main circuit to complete the inverter function. The function of the auxiliary power supply is to provide the DC working voltage for the control circuit. The protection circuit mainly realizes overvoltage protection, undervoltage protection, overload protection, short circuit protection, etc.
