Advantages sine wave inverter

Sine wave inverter output voltage waveform is a sine wave
Advantages sine wave inverter is: an output waveform is good, low distortion, interference to radio and communications equipment, low noise. In addition, protection function, high overall efficiency.
Disadvantages are: the line is relatively complex, high technical requirements for maintenance expensive.
By isolation mode PV inverter can be divided into:
(1) Independent 12v car inverter for photovoltaic systems
Individual inverter power supply system includes villages in remote areas, household solar power systems, communications signal power, cathodic protection, solar lights and other independent power systems with batteries.
(2) grid-connected photovoltaic systems Inverter
• grid system is connected to the power transmission grid photovoltaic system to power. By the PV module to the solar radiation received, after the high-frequency energy into high voltage DC-DC converter, the 300w solar inverter after the conversion with an 4000w inverter charger output frequency to the grid and the grid voltage, a sinusoidal AC current in phase.
