What is an inverter?<\/span><\/span><\/h2>\n

\"SolarInverters (inverter) is a device whose function is to convert the continuous DC electricity coming from the panels or batteries into an alternating current of 110\/220\/380 AC to operate home appliances or pumps or connect the solar energy system to the national electricity grid. <\/span>Basic Technical Characteristics of Solar Inverters:<\/span><\/span><\/p>\n

    Characteristics of AC Output waves<\/span><\/span><\/div>\n

    The household current operates on a pure sine wave called the Pure Sine Wave, and there is another wave called the Modified Sine Wave.<\/span><\/span>\"alternatingAs the picture shows, the red color shows the normal current, and the other colors show other forms of waves. This will make a difference with you in operating some devices that only work on the real sine wave. So when buying an inverter, we will find that some devices are described as producing a pure or modified sine wave or pure sine wave. Modified Sine Wave, and this will have a difference in the price and also in the quality of the devices that can be operated. It used to operate it sometimes, but a change occurred in the behavior of the device, for example the fan worked, but a change was noticed in its sound and the motor cycle, and this is a negative point that is compensated by the low price. <\/span>Modified sine wave inverters are not suitable for operating all devices that have AC motors, such as:<\/span><\/span><\/li>\n

    Inverter capacity – Rated Power<\/span><\/span><\/div>\n

    It is noted that the devices often express their consumption in watts, and some inverters express their capacity in volt-ampere VA, and this calls for attention when calculating the capacity and converting volt-ampere into Watt requires multiplication in the electrical power factor. The devices that can be loaded on it have a total of 600 watts.For the motors that are loaded on the inverter, the actual current must be calculated when starting the motor by making the necessary correction for the electrical power factor, and here you will calculate the loads that are expected to be loaded. Set a margin of increase in order to avoid overloading. The user must be careful and aware of the nature of the device, not to overload it, and respond to the warnings issued by the device when increasing the load by reducing loads, turning off some devices, or turning off the device altogether if it cannot bear it, especially with frequent power outages.<\/span><\/span><\/li>\n

    Low frequency and high frequency inverters<\/span><\/span><\/div>\n

    Low frequency vs High Frequency There are two types of inverters and without diving into theories, it can simply be said that there are differences in weight, cost, maximum capacity and noise.<\/span><\/span><\/p>\n

      \n
    1. A low frequency inverter uses large copper coils to convert current and is therefore heavy and expensive<\/span><\/span><\/li>\n
    2. A high frequency inverter uses electronic transistors to convert current.<\/span><\/span><\/li>\n<\/ol>\n\n\n\n\n\n\n\n\n

      Maximum power – Surge Power<\/span><\/span><\/td>\nThe maximum capacity is 4-8 times the continuous capacity. <\/span>That is, the 3 kilowatt inverter has a maximum capacity of at least 12 kilowatts, and this number is valid for starting induction motors such as air conditioners and washing machines. For example, a 3 kilowatt inverter has a maximum capacity of 12 kilowatts. <\/span>This number is sufficient to operate a 3-horsepower air conditioner<\/span><\/span><\/td>\nThe maximum power does not exceed twice the continuous power, and for the operation of rectifying motors, careful care must be taken in designing the size of the inverter<\/span><\/span><\/td>\n<\/tr>\n
