220v power inverter is a work in high curren

220v power inverter is a work in high current, high frequency power supply environmental products, the potential failure rate is very high. Therefore, consumers must be careful when buying. First, from the best power inverter output waveform is selected, it is best not lower than the quasi sine wave (modified sine wave); secondly, there must be a complete circuit of the inverter protection; Third, manufacturers have a good service commitment; s Fourth, the circuit and product proven over time to ensure that in the future the normal, safe and reliable use of the inverter.
