1000 watt power inverter Inverter FAQ u outside interference

The inverter may be due to a number of occasions in the strong electromagnetic interference, such as motors, power inverter, a strong magnetic field in the vicinity. 

Far away from the device similar to the above. 

u inverter does not respond 

1. Battery and inverter is not 800w car inverters‍ connected, re-connected. 

2. Battery poles reversed, the fuse blows. Replace the fuse. 

u The output voltage is low 

1. Overload, the load current exceeds the nominal current, turn off the part of the load restart. 

2. Input voltage is too low. Make sure the input voltage is within the nominal voltage range. 

u low voltage alarm 

1. Rechargeable batteries are needed. 

2. Battery voltage is too low or bad, recharge, 1500w power inverter‍ or check the battery terminals with a dry cloth to clean the terminals. 

u no output inverter 

1. Battery voltage is too low, re-charge or replace the battery. 

2. Load current is too high, closed part of the load to restart the inverter. 

3. Inverter over-temperature protection. Let inverter cool down for some time, and well ventilated place. 

4. The inverter fails to start, restart. 

5. Terminals reversed, the fuse is blown, 1000w charger inverter‍ replace the fuse. 

u inverter does not work 

Check the power switch, fuse and battery cable or cigarette lighter.‍

300 watt power inverter The pulse width modulation inverter technology

Basic square wave inverter circuit is simple, but the output voltage waveform harmonic content is too large, also both THD (current harmonic distortion) is too large; multi-phase Solar power inverters‍ superposition of harmonic content of a small power inverter output voltage waveform, That THD is small, but the circuit is more complex. The PWM pulse width modulation inverter, both the computer's circuitry, but also allows the output voltage waveform, which has been widely used. 

The so-called pulse width modulation PWM (Pulse Width Modulation, PWM), is made of a reference wave (typically a sine wave, the trapezoidal wave or sometimes zero sequence harmonics injected sine wave or square wave, etc.) of the modulation wave (Modulating Wave), and to N times the frequency of the triangular wave modulation wave (sometimes with sawtooth) the carrier (Carrier Wave) waveform comparison, the modulation wave is 1500w off grid inverter‍ greater than the portion of the carrier to produce a set of equal amplitude modulated wave is proportional to the width equivalent to a rectangular pulse sequence modulated wave with a substituted analog switch, and through the inverter power switch on / off control of the DC power into AC power, this technology is called pulse-width control inverter technology. Since the triangular carrier wave (or sawtooth) down degree models are linear change, so this technique is called pulse width control inverter technology. Since the triangular carrier wave (or sawtooth) is a linear variation of the vertical width, so this is also linear modulation, when the modulation wave is a sine wave, a rectangular pulse width of the output pulse sequence changes sinusoidally, the 800w car inverters‍ modulation technique is often also known as the sinusoidal pulse width modulation (Sinusoida PWM) technology.

500 watt power inverter Inverter relative concept

Convert alternating current to direct current method 24v bypass inverter‍ is rectified; while the direct current into alternating current method is an inverter. 

Rectifier, full-wave rectifier circuit is to use a single diode conduction properties, with four diodes connected into a bridge rectifier circuit (see figure below), so that the input is AC current, the waveform is a sine wave alternating current direction is , and the output terminal of the current waveform becomes the same 2500w inverter charger‍ direction and then the waveform obtained through the filter circuit to filter out the DC after.
