 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.
