4KW Low Frequency Inverter

4KW low frequency pure sine wave off-grid inverter - high efficiency and energy saving, long-lasting and durable.
As a leading inverter manufacturer in Foshan, the 4KW industrial frequency inverter we launched has the core advantages of ultra-high energy efficiency and ultra-long service life, helping global users to save electricity costs to the maximum extent and reduce the frequency of equipment replacement.
Core energy saving and durability advantages
1. High efficiency and power saving, reducing energy waste
Conversion efficiency up to 85%: using high-quality toroidal transformers to greatly reduce energy conversion losses, compared with ordinary inverters, it can save 10%-15% electricity per year.
Intelligent turning mode: no-load or power consumption <15W, automatically enters low power consumption state when there is no load, avoiding ineffective power loss. Dynamic power regulation: automatically adjust the output power according to demand to avoid over-power supply and improve the overall system energy efficiency.
2. It can be connected to the solar energy system, select the battery priority mode, and give priority to solar power supply, which not only saves electricity bills, but also provides continuous power guarantee during power outages.

3. Ultra-long service life, reduced maintenance cost
Built-in transformer: all-copper winding, high temperature resistance, anti-aging, designed service life > 10 years.
Protection design: wide temperature operation (0℃~60℃)
Full protection for overload/short circuit/overtemperature
Technical highlights
Pure sine wave output: avoid equipment damage.
Intelligent battery management: three-stage charging algorithm, extending battery consumption by more than 30%.
Design: Faulty parts can be quickly replaced.
Global service guarantee
Relying on the complete supply chain of Foshan factory and the world (Africa, Southeast Asia, America, etc.), we provide:
1 year warranty
24-hour remote technical support
Localized spare parts supply
Choosing our 4K choose W inverter is not just a device, but also a long-term stable energy-saving and durable experience!
