The powerful Thor 1000 Watt power inverter features state-of-the-art circuitry designed to handle temporary high surge loads to start and run electric tools, pumps and other electric equipment on your truck from a 12V DC power source. The AC output waveform of the Thor TH1000 power inverter is known as a modified sine wave. The alternation of the direction of current in the primary winding of the transformer produces alternating current (AC) in the secondary circuit.
The quality of the output wave form (230 volt AC) from the inverter determines its efficiency. Alternating current has continuously varying voltage, which swings from positive to negative. Modified sine wave is designed to simulate a sine wave since the generation of sine wave is expensive. A watt hour (or Kilo Watt hour – kWh) is simply how many watt times, how many hours the device is used.
For example if you wants to run 400 watts load on 12 volt battery for 3 hours, then the capacity of the battery should be minimum 100 Ah.
Before selecting the inverter, it important to calculate the total power consumption of the appliances that are going to be connected to the inverter. It is important to note that the power consumption (Current drain) increases when the driving voltage decreases. Before purchasing an Inverter, it is necessary to calculate the power requirements of the loads that are going to be connected. If you wish to use 2 Fans, 2 Tube lights and 1 TV, the total power consumption will be around 380 Watts. Generally, Ampere-hour is used in specifying batteries, as they have constant voltage output.
Sir, your way of defining is really impressive.Is it possible for you to explain how to choose Transformer size for diffrent capacity Inverters.
Thank u very much for all your advice,pls can you help me out with 500va inverter design calculations? If a charge cut off facility is in the Inverter, current consumption from AC supply depends on the duration of charging.Tubular battery or Lead Acid battery takes current depending on many factors like age, water level, specific gravity of acid, plates condition etc. The output voltage from the inverter is ranging from 265 to 280 Volts when there is a power cut. If I need a backup of 8-12 hours for my computer (one home PC with 15″ CRT monitor), what specifications of inverter and battery do I need.
Dear User, Please use the drop downs below to locate your city by first selecting the country and then the state. Each of this kind of inverters is complete functional inverter, but not module, and the frame of each inverter is completely same.
There is the whole protection and audio-visual alarm system in the internal of power inverter.
Suoer Solar Inverters 1000w Inverter 12V 220V Smart Power Inverter, View 12v 220v inverter, SUOER Product Details from Foshan Suoer Electronic Industry Co., Ltd. Run electric tools, pumps and other electric equipment on your truck from a 12V DC power source. These power inverters are specifically manufactured for extreme duty and are perfectly suited for trucks and industrial applications. It is a stepped waveform that has characteristics similar to the sine wave shape of utility power.


The quality of the inverter output wave form is expressed using Fourier analysis data to calculate the ‘Total Harmonic Distortion’ (THD). The major advantage of sine wave inverter is that all of the house hold appliances are designed to operate in sine wave AC. This waveform consists of a Flat Plateau of positive voltage, dropping abruptly to zero for a short period, then dropping again to a flat plateau of negative voltage. It is more economical but may present certain problems with appliances like microwave ovens, laser printers, digital clocks and some music systems. They can run simple appliances without problems but not much else.Square wave voltage can be easily generated using a simple oscillator. If a device uses 100 watts, it is simply the voltage times the ampere (rate of current).If the device takes 10 Amps at 12 Volt DC, it uses 120 watts power. Peak power is the maximum power that an inverter can supply usually for short time.Some heavy current appliances like motor and refrigerator requires a startup peak power than they require when running.
When the input voltage drops in the domestic supply lines from 230 V AC to 200 VAC, electric devices will consume more current.
Mid size inverter (500VA to 800 VA) will handle most of the low power household appliances.
But the cost of the inverter and battery will be high compared to a 12 volt inverter and 12 volt battery. The working of the inverter depends on many factors like conducted load, battery efficiency and maintenance. If you still can not find your city in the list, please CLICK HERE to submit a request for inclusion of your city. It can provide a full range of protection, mainly over-voltage protection, under-voltage protection, over-heat protection, overload protection, short circuit protection, reverse polarity protection.
If you require further details regarding the transaction data, please contact the supplier directly. The first stage is a DC-to-DC conversion process that raises the low voltage DC at the inverter input to 145 volts DC.
In the basic design of the home inverter a DC (battery) source is connected to a transformer through the center tap of the primary winding. THD is the square root of the sum of the squares of the harmonic voltage divided by the fundamental voltage. Power from the Grid is carefully regulated to get a pure sine wave and also the sine wave radiate the least amount of radio power during long distance transmission.
Another advantage is that the sine wave is a form of soft temporal rise voltage and it lacks harmonic oscillations which can cause unwanted counter forces on engines, interference on radio equipments and surge current on condensers. With the help of a transformer, the generated square wave voltage can be transformed into a value of 230 volt AC or higher. The first thing you have to consider about the inverter system is its maximum peak power or surge power and steady current supply. If the total load connected to the inverter is 400 watts then the minimum inverter size should be 400 x 1.15. High capacity batteries (100 Ah, 150 Ah) are used to power inverters to get sufficient backup time.
For example a load rated 300 Watts (like Fridge) operating in 230 volts uses 1.4 Amps in one hour. P=VI, so when voltage varies current consumption by appliances also varies, but the total wattage or P remains same.


I’ve scanned a number books related to power electronics but could not understand till date. But the battery Ah must be more than 150 Ah for this long duration back up.Use the formula given in the article to calculate the battery Ah. A switch is rapidly switched back and forth to allow current to flow back to the battery following two alternate paths through one end of the primary winding and then the other. This short pause at zero volts gives more power to 50 Hz fundamental frequency of AC than the simple square wave. Instruments using SCR (Silicon Controlled Rectifier) in the power supply section behave badly with modified sine wave.
The same load takes 1.5 Amps if the line voltage drops to 200 volt during peak hours (6pm- 9 pm). In a system, when it is working, the master inverter must be power on, and the working quantities of the other slave inverters depend on the usage of the load. Its quality is excellent and almost all electrical and electronic appliances work well in sine wave inverter.
The SCR will consider the sharp corners of the sine wave as trashes and shut off the instrument. Proper charging of the battery and its efficiency to hold charge are two very important aspects. Many of the Laser printers behave like this and fail to work in inverters and UPS providing modified sine wave power. Therefore inverters must be’ sized’ for the maximum peak load and typical continuous power. This ‘surge capacity’ will vary considerably between inverters and even with in the same brand. Input voltage from the AC lines should be close to 230 volts for proper charging of the battery. Inverter should switch on charging immediately when the battery voltage reduces to 12 volts.
Charging current depends on the time taken to complete the charging process and also the ‘charge condition’ of the battery. If the battery is discharged to 80% of its efficiency, it will take 5 to 7 Ampere current for charging during the first few hours.
Cooler of fan and working status are intellectually controlled by MCU, which mostly prolongs its service life and helps to save the power consumption11.
So a high capacity inverter is a good choice because, if the load increases above the rated capacity of the inverter, it can lead to hazardous results. During boost charging, around 5 to 7 ampere current will utilized and during trickle charging only 25 to 50 milli ampere current will be utilized.
