Why Use Low-Frequency Pure Sine Wave Off-Grid Inverters?
 
Low-frequency pure sine wave off-grid inverters are designed to provide a stable and reliable power source for various applications. These inverters are built with robust transformers, making them ideal for handling high surge loads and offering superior power quality. Here’s why choosing low-frequency pure sine wave inverters is beneficial:
 
 
Robust and Durable: These inverters are designed with heavy-duty transformers, providing durability and long-term reliability, especially in demanding off-grid environments.
 
 

 

Pure Sine Wave Output: Pure sine wave inverters produce a smooth, consistent wave, similar to the power from the grid, ensuring that sensitive electronics and appliances operate efficiently without the risk of damage.

 

Versatility: Low-frequency pure sine wave inverters can handle various loads, from residential appliances to industrial equipment. They are versatile and can be used in both off-grid solar systems and backup power applications.

 

Improved Efficiency for Heavy Loads: Ideal for powering large and complex systems, these inverters perform well under heavy loads and can maintain efficiency, providing a reliable power supply for extended periods.

 

 

Multi-Protection Features: built-in protection features, such as battery overcharge, over-discharge, and short-circuit protection, high-low voltage protection, overload, short-circuit protection,under-voltage and over-temperature protection, overvoltage etc. ensuring the longevity of your battery bank 、inverter and appliance.

Three-Phase Low-Frequency Pure Sine Wave Inverter: 50K, 60KW, 80KW, 100KW, 200KW Models with Touch LCD

 

 

Discover the versatility and reliability of our three-phase low-frequency pure sine wave inverters, available in 50K, 60KW, 80KW, 100KW, and 200KW models. With advanced touch LCD functionality and dual operating modes, these inverters provide seamless power management for off-grid and backup applications.

 

Touch LCD Features & Benefits

 

1. Battery Priority Mode (Off-Grid Mode)

First Priority on Battery Power: In off-grid scenarios, our inverter prioritizes battery power to supply AC loads. Ideal for locations without a utility grid, such as remote solar power systems.

Efficient Battery Usage: Continues drawing power from the battery bank until reaching a predefined minimum state of charge. Non-critical loads are automatically shut off to conserve battery life for essential equipment.

Optimized for Solar Power: In events like nightfall or low solar output, the system relies solely on battery power. If integrated, a backup generator can be automatically activated to ensure continuous operation.

 

2. Utility Grid Priority Mode (Backup Mode)

First Priority on Grid Power: In backup mode, the inverter draws AC power from the utility grid first, reserving battery power for outages. This prevents unnecessary battery drain when the grid is stable.

Automatic Battery Charging: When connected to the grid, the inverter charges the battery bank using solar power or other available sources, maintaining optimal battery levels for backup use.

Seamless Transition: On loss of grid power, the inverter instantly switches to battery mode with minimal disruption, ensuring uninterrupted power supply to both critical and non-critical loads. A backup generator can be set to start automatically to either continue powering loads or recharge batteries.

 

Touch LCD Interface for Easy Operation

Our inverters come with an intuitive LCD touchscreen interface, making it simple to switch between Battery Priority and Utility Grid Priority modes. The easy-to-use display ensures that users can quickly select the right operating mode based on current conditions without any manual switching or guesswork. This functionality ensures that your system always behaves as intended, optimizing the use of solar, battery, generator, and grid power inputs.
