12-volt and 24-volt 48-volt inverter What's the difference?

The inverter output is the same as 220V, but not the same as the input voltage. To see what the power of your own most convenient, you can choose which of the 24v inverter  In addition, the input voltage is high, the use of undervoltage protection will be more wide, easier to use.
If 12V input inverter, less than 10V, the protection of the general will not work (most products). 48V input to the inverter 41 volt only protection.

Inverter structure and working principle

The inverter is a power adjusting means consisting of a semiconductor device, mainly for converting the DC power into AC power. Generally composed of a boost circuit and an  car inverters  bridge circuit. Boosting circuit boosting the DC voltage of the solar battery to the inverter output control DC voltages required; put the bridge circuit of the inverter DC voltage equivalent to the boosted common frequency is converted into an AC voltage. The inverter is constituted by the main switching element such as a transistor by the switching element regularly repeating ON - OFF (ON-OFF), the output of the DC input to AC. Of course, this is simply an  grid inverters  output waveform generated by the opening and closing of the circuit is not practical. Generally requires the use of a high frequency pulse width modulation (SPWM), brought close to the sine wave voltage across the width becomes narrow, the center voltage of the sine wave is widened, and in a half cycle of the switching element is always in one direction at a constant frequency operation, the thus formed a pulse wave train (quasi-sine wave). Then let the pulse wave form by a simple sine wave filters.

Power Inverter Precautions

1 ) TV, monitor , such as a motor when starting the peak power , although the power converter can withstand twice the nominal peak power , but some of the electrical power in accordance with the peak power required may exceed the peak output power of the converter , overload induced current is turned off . While mppt solar controllers multiple appliances could happen , then you should turn off electrical switches , open the converter switch , and then turn on electrical switches one by one , and should be the first to turn on the highest peak of appliances.
2 ) In use, the battery voltage begins to drop when the input DC voltage converter down to 10.4-11V, alarms emit a buzzing sound , then a computer or other sensitive electrical appliances should be promptly closed , if ignored alarm sound, the conversion will the voltage to 9.7-10.3V , the automatic shutdown to avoid excessive battery is discharged , power protection turns off, the red light is on ;
3 ) shall2000 watt power inverter

 start the vehicle , to the battery charge to prevent power failure, affect the car started and battery life ;
4 ) Although the converter is no overvoltage protection , input voltage exceeds 16V, may still damage the converter ;
5 ) After continuous use , the shell surface temperature to rise to 60 ℃, attention to smooth airflow , temperature sensitive objects away from the impact

.

grid inverter

Due to the diversity of architecture, is bound to lead to the diversity of solar panel installation, in order to make the solar energy conversion efficiency is the highest while taking into account the architectural appearance, which requires the diversify our 12 volt power inverters, the best way to accomplish the conversion of solar energy. The solar inverter is popular now for the world: centralized inverter, string24v inverter, multi string inverter and component inverter, the inverter is analyzed using several occasions.

The principle of power inverter

Power inverter (power) is a can of DC12V direct current into alternating current, and AC220V the same power, for general electric, is a power converter and convenient. The power inverter is the electronic circuit by internal settings, automatic battery protection function. The power 4000 watt power inverter is applicable not only to the vehicle system, as long as there is a DC12V power supply, can use the power vehicle power inverters, convert DC12V to AC220V AC, bring convenience to your life.
