  • What are the factors to consider when choosing a solar controller? 2021-01-12

    The solar controller is a relatively important device in the photovoltaic power generation system. It is very important to choose a suitable and powerful solar controller. 1. The voltage of the solar panel We only need to pay attention to the working...

  • What is the difference between a square wave inverter and a sine wave inverter? 2021-01-12

    There are two types of inverters, square wave inverters and sine wave inverters. Although square wave inverters have simple structure and low cost, they are not suitable for inductive and capacitive circuits due to too many harmonics. The price of si...

  • Photovoltaic off-grid inverter solar power generation system 2021-01-12

    The photovoltaic off-grid power generation system is mainly composed of six parts: solar modules, brackets, solar controllers, off-grid inverters, batteries and distribution boxes. After the solar cell module is connected to the solar controller, it...

  • What are the inspection steps for solar inverters? 2021-01-12

    When the solar inverter is turned off, the closing operation on the LCD panel is required first, and then the inverter is controlled to be turned off. After the circuit breaker that outputs the AC output of the inverter stops rotating and the switch ...

  • What are the characteristics of solar inverters? 2021-01-12

    A solar inverter is a power adjustment device composed of semiconductor devices, which is mainly used to convert DC power into AC power. Solar inverter not only has the function of DC and AC conversion, but also has many characteristics1. High perfor...

  • What are the little knowledge about battery charging? 2021-01-12

    1. When UPS is floating charging, please use charging voltage 2.275V/single cell (set value at 20°C) for constant voltage charging or constant current charging with a current below 0.002CA. When the temperature is below 0C or above 40C, it is necessa...

  • What is the knowledge about UPS battery? 2021-01-12

    1. About dischargePlease keep the battery temperature within the range of -15℃-+50℃ when discharging.Please control the continuous discharge current below 3CA (H below 6CA).The end-of-discharge voltage varies according to the magnitude of the current...

  • What is the working principle of a photovoltaic inverter? 2021-01-12

    Inverter is a DC to AC transformer, it is actually a voltage inversion process with the converter. The converter converts the AC voltage of the grid into a stable 12V DC output, and the inverter converts the 12V DC voltage output by the Adapter into ...

  • What are the functions and characteristics of the inverter? 2021-01-12

    1. FunctionThe inverter converts direct current (battery, storage battery) into alternating current (generally 220v50HZ sine or square wave). In layman's terms, an inverter is a device that converts direct current (DC) into alternating current (AC). ...

  • What are the precautions for using the inverter?(1) 2021-01-12

    1. The DC voltage must be consistentEach inverter has a DC voltage value, such as 12V, 24V, etc. It is required that the battery voltage selected must be consistent with the inverter's DC input voltage. For example, a 12V inverter must choose a 12V b...

  • What is an inverter? 2021-01-12

    Inverter is a converter that converts DC power (battery, storage battery) into fixed-frequency, constant-voltage or frequency-modulated alternating current (usually 220V, 50Hz sine wave). It is composed of inverter bridge, control logic and filter ci...
