Comparison of the touch screen and button screen of the home solar energy storage LiFePO4 battery In summary, touch screens and button screens have their advantages in solar energy storage LiFePO4 batteries. Users can choose a more suitable product based…
Common photovoltaic controllers are mainly PWM and MPPT. Many friends have doubts about the difference between the two. Here we briefly explain. PWM: Pulse-Width Modulation Pulse width modulation (PWM) refers to the use of microprocessor digital output to control analog…
Owners and maintenance experts of photovoltaic power stations, are you often troubled by the “leakage fault” of the inverter? Especially in the humid rainy season, once the alarm message sounds, the power generation will stop directly, and the loss is…
Recently, I have received many private messages from customers saying that the screen of the inverter in the power station suddenly “blackened” and it would not light up even after tapping and hitting the screen, which made them panic. Today,…
Whether it is an old friend or a new customer, as long as they propose to come to China to participate in the industry exhibition, it means that we will face a new round of bidding, and there is even…
The following is a detailed analysis and comparative summary of the R&D direction in the 2023 annual reports of six photovoltaic inverter manufacturers, including Sungrow Power Supply, Huawei Digital Energy, Jinlong Technology, GoodWe, Homai Co., Ltd. and Sineng Electric: 1.…
In the daily operation and maintenance of photovoltaic power stations, the automatic voltage control (AVC) system plays a vital role. It is not only the key to ensure the stability of the grid voltage, but also an important tool to…
Photovoltaic transformers are the backbone of photovoltaic power generation systems. They are not only the bridge between photovoltaic arrays and power grids, but also have to convert low-voltage direct current generated by photovoltaic arrays into high-voltage alternating current, so that…
As the core equipment of the solar power generation system, the photovoltaic inverter undertakes the key task of converting direct current into alternating current. The stability of the IGBT (insulated gate bipolar transistor) module, as the core power device of…
(Pushing his black-framed glasses, a sneer appeared on his lips) Ladies and gentlemen, please hold your seats tight, and listen to me, an old hand in the industry, have a “complaint conference” in the photovoltaic industry. Longi Green Energy? Oh,…
