Hybrid solar inverter is one of the important system balance (BOS) in photovoltaic array system, and it can be used with general AC power supply equipment. In this article, I will introduce hybrid solar inverters to a certain extent, hope it will be helpful to you.
Classification of hybrid solar inverters.
All of the company's hybrid solar inverter products.
Hybrid solar inverters can be divided into the following three categories:
Independent hybrid solar inverter: used in an independent system, the photovoltaic array charges the battery, and the hybrid solar inverter uses the DC voltage of the battery as the energy source. Many stand-alone hybrid solar inverters also integrate a battery charger, which can charge the battery with AC power.
Grid-connected hybrid solar inverter: The output voltage of the hybrid solar inverter can be fed back to the commercial AC power source, so the output sine wave needs to be the same phase, frequency and voltage as the power source. The grid-connected hybrid solar inverter will have a safety design, if it is not connected to a power source, it will automatically turn off the output. If the grid power trips, the grid-connected hybrid solar inverter does not have the function of backing up power supply.
Grid-connected hybrid solar inverters feed back electrical energy to the grid. If the grid is cut off, it needs to quickly cut off the power supply to the grid. This is the requirement of the National Electrical Code (NEC) to ensure that the The grid hybrid solar inverter will also be shut down to avoid harm to personnel who maintain the grid.
The grid-connected hybrid solar inverters currently on the market use many different technologies, including the use of newer high-frequency transformers, traditional power-frequency transformers, or transformerless architectures. The high-frequency transformer does not directly provide 120 V or 240 V AC power, but a computer-controlled multi-step program that converts the power supply to high-frequency alternating current, then to direct current, and finally to the voltage and frequency required by the power supply.
The standby hybrid solar inverter is a special hybrid solar inverter. This kind of hybrid solar hybrid solar inverter can provide AC power to the specified load when the grid power is tripped, so it needs to have an islanding effect protection function.
Foshan New Energy Electric Technology Co., Ltd. was established in 2004. Our team has more than 10 years of experience. It adopts digital design and is suitable for various loads. The company's main products are: solar generator sets, solar inverters, solar charge controllers and photovoltaic combiner boxes. For example, hybrid solar inverters include MPPT hybrid solar inverters and NKM series hybrid solar inverters.
