On grid inverter or grid tie inverter from Inverter.com, can convert direct current into alternating current. Its AC output can synchronize with the frequency and phase of mains supply. On grid inverters are commonly used in applications where direct current voltage sources are connected to the grid, such as solar panels and small wind turbines. The output voltage frequency of the solar grid tie inverter needs to be same as the grid frequency (50 Hz or 60 Hz). A MPU in the grid tie inverter can sense the AC waveform of the power grid and generate voltage back to the power grid based on the waveform.
Different voltage power inverter have different prices. Power inverter is a device that can convert DC (the battery and accumulator jar) into AC (normally the sinusoidal wave of 220V and 50Hz). It is composed of inverter bridge, control logic and filter circuit. With a power inverter, direct current (battery, switching power supply, fuel cell, etc.) can be converted into alternating current to provide stable and reliable power protection for electrical appliances, such as laptops, mobile phones, handheld PCs, digital cameras, and various instruments. Inverters can also be used with generators, which can effectively save fuel and reduce noise. The power inverter has a wide range of uses. It can be used in various vehicles, such as automobiles, ships and aircraft.
Off-grid solar inverters can work independently after leaving the grid, which is equivalent to an independent small grid. It is also similar to a voltage source, which mainly controls its own voltage. Off-grid inverters can be loaded with resistance and capacitance, inductive motors, and other loads. It has quick response, anti-interference, strong adaptability, and practicability features, and is the preferred power supply for power failure and outdoor power supply.
