Sine wave inverters are widely used in various types: microcomputer systems, communication systems, homes, aviation, emergencies, communications, industrial equipment, satellite communication equipment, military vehicles, medical ambulances, police cars, ships, solar and wind power generation, etc. . The location of the backup power source can constitute an EPS emergency power system. The performance is as follows:1)…

As an important electrical equipment within the photovoltaic power generation system, the inverter is equipped with various protection functions, including the following basic protection functions.(1) DC bus overvoltage protection. The inverter continuously detects the DC bus voltage. When the DC voltage is detected to be higher than 1000 V several times in a row, the…

The inverter converts DC power (battery, storage battery) into AC power (generally 220v50HZ sine or square wave). Emergency power supply generally inverts the DC battery into 220V AC.Simply put, an inverter is an electronic device that converts low voltage (12 or 24 volts or 48 volts) direct current into 220 volts alternating current. Because we…

In photovoltaic off-grid systems, the power of the off-grid inverter is generally determined based on the user’s load type and power.Loads are classified according to their impedance properties: resistive loads, inductive loads, and capacitive loads. Resistive load: A load with no phase difference between current and voltage is a resistive load, such as rice cookers,…

Advantages and Disadvantages of Centralized InvertersCentralized inverter: The equipment power is between 50KW and 630KW. The power device uses high-current IGBT. The system topology uses DC-AC first-level power electronic device to convert full-bridge inverter and power frequency isolation transformer. The protection level is average. for IP20. Larger in size, vertical installation indoors. Main advantages of…

High-frequency transformers refer to transformers that work at high frequencies and function as energy converters. Because the frequency of the magnetic field is very high, eddy currents will be generated in the silicon steel sheets (the small magnets in the silicon steel sheets cannot keep up with the conversion speed), so high-frequency transformers Generally, “high…

How to calculate battery capacity for off-grid solar systems 10kw photovoltaic systemSolar photovoltaic system battery capacity method: 1: Determine the total power of the load, pay attention to the load power, not the rated power of the power supply; 2: Determine the emergency time; 3: Determine the DC voltage level of the power supply; The…

Off-grid solar photovoltaic systemThe photovoltaic off-grid power generation system mainly consists 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 first meets the user’s load, and then stores the remaining power in the battery for use at night…

When the photovoltaic inverter is shut down, the shutdown operation on the LCD panel is first required, and then the inverter is controlled to shut down. After the circuit breaker outputting the AC output of the frequency converter stops rotating and the switch behind the frequency converter is turned off, the frequency converter will switch…

A solar inverter can be defined as an electrical converter that converts the uneven DC (direct current) output of solar panels into AC (alternating current). This current can be used in different applications, for example in a viable grid or in an off-grid grid. In photovoltaic systems, this is the dangerous BOS (balance of system)…
