inverter 12v 220v 1000w

Adopt CPU control, the line is simple and reliable; SPWM pulse width modulation technology is adopted to output pure sinusoidal wave with low distortion and stable frequency.

The use environment of UPS should be well ventilated, conducive to heat dissipation, and keep the environment clean.

The output load of UPS should be controlled at about 60% with high reliability.

When the municipal power grid conforms to the input range, it will supply power to the load through AC/DC and DC/AC dual transformation. 

In the past, there were some doubts about the system without transformers, but also to supply power to the grid, mainly because there is no galvanic isolation between the DC circuit and the AC circuit. 

If the DC terminal fails, a large current will flow to the AC terminal. However, since 2005, the National Fire Code of the National Fire Protection Association (NFPA) has allowed transformerless inverters. VDE 0126-1-1 and IEC 6210 have also allowed and defined the security mechanisms required for such systems. 

First, a residual current or ground circuit is required to detect an abnormal short circuit, and an insulation test is also performed to confirm the separation between the DC circuit and the AC circuit.

Many solar inverters are designed to be connected to the grid, and the inverter will not operate unless the grid is detected. This type of inverter also has a special circuit that precisely matches the size, frequency and phase of the output voltage with the power supply.
