inverter 1000w 24v

PWM pulse width control technology, pulse charging function, the use of three charging mode, so that the charging time to reduce 1/3, effectively protect the battery life.

Provide slow startup function, provide high and low voltage alarm and provide high and low voltage turn-off protection function.

CPU management, intelligent control, modular composition, more convenient after-sales maintenance;

LED+LCD display, can visually display all the running parameters of the machine.

The LED indicates the input voltage range, load power range, normal output and fault status

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.
