Home power inverter system  is a system that converts solar energy into electric energy by using solar cell module, storage battery, controller, inverter and other auxiliary equipment. During the day, under the illumination condition, the solar cell module generates a certain electromotive force, and the solar cell array is formed by the series of components, so that the voltage of the square matrix can reach the requirement of the system input voltage.Then charge the battery using the charging and discharging controller, and the electric energy converted by the light energy can be stored. In the evening, the battery group is provided with an input power for the  solar inverter , the DC is converted into AC through the inverter, for the use of AC equipment. The discharge of the battery pack is controlled by the controller to ensure the normal use of the battery. PV power station system should also have limit load protection and lightning protection devices, to protect the syst...

In common, that is, the high power electrical products applying the principle of electromagnetic induction, such as electric motors, compressors, relays, fluorescent lamps and so on. This type of product requires a much larger current (about 5-7 times) than the current required to maintain the normal operation. For example, a refrigerator in the normal operation of about 150 watts of power consumption, the power can be up to more than 1000 watts. In addition, due to inductive load will generate the back EMF voltage in the moment of the power supply is switched on or off, the voltage peak is far greater than the voltage value which inverter can stand, it is easy to cause the instantaneous overload of vehicle inverter, affects the using life of inverter. When measuring the AC output of the modified sine wave vehicle inverter by using a common universal meter, the voltage is 20V lower than 220 volts. Problems occur in the operation of precision equipment, can cause high frequency interfe...

Pure sine wave output: Relative to square wave or modified sine wave (step form) has a stronger load effect and capacity. Equipment can be loaded with inductive load and any other types of general AC load, with refrigerators, TV sets and radios and other equipment without interference and noise, and will not affect the performance and life of load equipment. High stability: Due to the system with the improved protection function of over-voltage, under voltage, overload, overheating, short circuit, reverse connect and so on, so as to ensure the stability of the system. LED display: LED display battery voltage and output voltage as well as state parameters. High efficiency transformer isolation: high efficiency, low no-load loss. Digital intelligent control: The core device by powerful microcontroller to control, making the structure of the external circuit simple, and control method and control strategy is powerful and flexible, so as to ensure the excellent performance and stabi...

Inverter output function: Open the inverter switch in the front of the panel, the inverter is about to change the DC power of the battery into pure sine wave alternating current, output by the ACOUTPUT of the rear panel. Automatic voltage stabilizing function: When the battery voltage is fluctuated between the undervoltage and the overvoltage, and the load is changed in the rated power, the device can automatically output voltage. Overvoltage protection function: When the battery voltage is greater than the overvoltage, the device will automatically cut off the inverter output, the front LCD panel display “overpressure”, the alarm sound and the buzzer sends out ten seconds. When the voltage is down to “overvoltage recovery point”, the inversion recovery work. Undervoltage protection function: When the battery voltage is lower than the “undervoltage point”, in order to avoid excessive discharge to damage the battery, the device will automatically cut off the output. At this...

1.Using environmental conditions Solar off grid inverters  normal use conditions: altitude is not more than 1000m, air temperature of 0～+40℃. 2.DC input power supply condition Input DC voltage fluctuation range: ±15% of battery rated voltage. 3.Rated output voltage Under the specified input power supply conditions, when output the rated current, the rated voltage of the inverter should be output. 4.Rated output current Under specified output frequency and load power factor, the rated current of the inverter should be output. 5.Rated output frequency Under the specified conditions, the rated output frequency of the fixed frequency inverter is 50Hz: 6.Maximum harmonic content When the  pure sine wave inverter  under resistive load, the maximum harmonic content of output voltage should be less than or equal to 10%. 7.Overload capacity Under specified conditions, in a relatively short period of time, the capacity of the output of the inverter over the rated curre...

Temperature and humidity are the two main reasons for the failure of  outdoor rated UPS . The electronic systems may does not contain the design of against harsh environmental conditions, in order to meet the protection of electronic equipment in the indoor and the outdoor environment, the industry invested a lot of time in dealing with the problem of cooling treatment. The cooling treatment of  outdoor UPS systems  has become a very important issue. In fact, it is only necessary to eliminate the problem of internal heat which is caused by the size limitation and the light radiation in the face, so it can solve the heat dissipation problem of outdoor electronic equipment. The heat management of the  outdoor AC UPS  must make a choice for the environmental conditions of the equipment. The equipment is usually divided into indoor equipment and outdoor equipment. Indoor equipment including installation in the central office (CO) or client switching equipment (...

1.After the intention to purchase an EV, check the installation conditions Before the installation of  EV charging piles , the first thing you need to do is to survey whether you have matched the installation conditions, such as whether there is a fixed parking spaces, how far from the power grid lines, etc.. The simplest method is to ask residential property for the situation. Property mustknow some simple relevant installation issues, such as the installation of the program, the use of electricity, installation area and so on. In fact, you don’t have to worry about that, because themanufacturers will send personnel to solve the professional problems later. 2.Go to 4S shop to apply for the survey of installation field, select the type of charging piles When the staff survey the site, it is best to ask the property together to deal with the installation issues, thus can not only have the professionals to answer questions about the property, but also improve the installation effi...

In the process of using  IGBT UPS , often by the impact of capacitive or inductive load, overload and even short circuit, etc., as well as the wrong operation of UPS, may cause IGBT damage. IGBT in the use of the main reasons for the failure of the following conditions: IGBT has a certain anti over current capacity, but must pay attention to prevent the current damage. IGBT composite device has a parasitic thyristor, so has the latching effect. After the latching effect occur, the drain current cause excessive high power consumption, and finally lead to the damage of the device. In order to avoid the IGBT happens latching effect and damage, the circuit design should ensure the IGBT maximum working current should not exceeding the IDM value of the IGBT. Also note that may be appropriate to increase the driving resistance Rg to extend the shutdown time, reduce the di / dt of IGBT. Driving voltage size will also affect IGBT latching effect, low driving voltage, under over current...
