The Constraction of ESG Low frequency 1KW 2KW 3KW 5KW 24v 48v DC mppt controller Pure sine wave solar power inverter :
Transformer
ESG’s inverters are all made of pure-copper coils, which have the best conductivity and thermal diffusivity while comparing with pure-aluminum coils or copper- clad-aluminum coils.
power inverter Panel
The power inverter panel is made of high-quality imported MOSFET and IGBT electric tubes, and has high power inverter transferring rate 90%.
Control Panel
Control panel is mainly made of iron with professional installing, which has the protection against overload, short-circuit, overvoltage, under-voltage, and over-temperature, etc.
Iron Box
Iron box is made of 1.5mm thick iron, which is stable enough that could highly protect against extrusion, knocking, falling down, etc.
LCD Display
You could find out the full details about inverter and PV through the liquid crystal display.

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
