Low frequency solar inverter is a power conversion device that converts direct current (DC) to alternating current (AC). It has strong overload and shock resistance capabilities and is widely used in many fields.
Low frequency solar inverter typically output a standard, smooth, pure sine wave with low waveform distortion, almost perfectly matching the waveform of the mains power.

These characteristics make low frequency solar inverter outstanding in specific applications. They maintain high stability, especially when frequently starting high power motors or handling impact loads (such as power tools). Furthermore, for precision equipment sensitive to power quality (such as high end audio equipment, medical devices, and older motors), low frequency solar inverter provide the safest and most stable power without generating high frequency harmonic interference.
Xindun offers a variety of low frequency solar inverter, such as the LU, LF, LS, WF, ESS, and ESS-Li series.

Low frequency solar inverter primarily use low frequency transformers as their internal structure. While low frequency solar inverter have higher conversion efficiency, they do incur some no load losses during energy conversion. However, our low frequency solar inverter can reduce these unnecessary losses through ECO mode settings.
The ECO mode of the Xindun low frequency solar inverter is a working mode designed to optimize battery energy utilization. The core of it is to achieve energy saving by dynamically adjusting the inverter output state.
The core of the low frequency solar inverter's ECO mode is to automatically control the start and stop of the inverter output based on the load size, avoiding unnecessary battery drain under light loads.
When the load is less than 5% of the rated load (20% for WF series 8-40kW), the inverter will start and stop periodically, intermittently interrupting the inverter output to reduce the continuous power consumption of the battery.
When the load exceeds 5% of the rated load (20% for WF series 8-40kW), the inverter maintains continuous inverter output without interrupting power supply, ensuring normal operation of the equipment.
This mode is suitable for lightly loaded devices with low requirements for power supply continuity. Intermittent interruption of output usually does not affect use, and the load is in a lightly loaded state for a long time, such as small standby devices, low power sensors, monitoring equipment, and ordinary lighting equipment.
The ECO mode of the Xindun low frequency solar inverter only applies to the battery inverter output. When powered by mains power, the inverter operates in normal mode and does not trigger intermittent start stop.
When dealing with equipment that requires extremely high power supply continuity, intermittent power outages can severely impact operation and even damage the equipment. In such cases, the inverter's ECO mode is unsuitable, and this is something to be very careful about! Examples include precision electronic equipment, uninterrupted communication equipment, medical equipment, industrial control equipment, and equipment sensitive to voltage stability.
