Crafted with durability and top-notch quality as the cornerstone of its design, this full sine wave power inverter is engineered to endure over a decade even in the most challenging environments. Our 12KW full sine wave inverter boasts minimal power loss, maintaining an average THD of 3%, with idle consumption standing at a mere 180 watts. Notably, its peak DC to AC efficiency reaches an impressive 90%, ensuring optimal performance in various applications.

The AC/battery priority switch, denoted as SW5, offers two operational modes. In AC priority mode, during a utility AC power outage, the transfer relay disengages, seamlessly shifting the load to the inverter output. Upon the restoration of AC utility power, the relay engages, smoothly transferring the load back to the AC utility source. In solar systems, opting for battery priority is recommended for enhanced efficiency and performance.

The Large Capacity Low Frequency Off-Grid Inverter is a versatile unit that integrates the functionalities of an inverter and battery charger to ensure continuous and uninterrupted power supply.

The high-capacity inverter features a direct-connect terminal block, enabling users to exceed its 12,000 watt capacity and utilize its 300% surge power (up to 36,000 watts for 20 seconds as previously mentioned). It serves as an essential emergency backup power solution for homes, businesses, and extensive off-grid applications.

Another common use of this inverter is for RV and vehicle modifications, such as powering lights and appliances in off-grid cabins. It's also suitable for supplying electricity to mobile businesses or offices, as well as running camping equipment. It's the optimal choice for large power systems.

FAQ

How to connect this to a home with the multiple phase system?

This inverter only supports dual phase outputs of 120V and 240V, and is not compatible with multiple phase systems.

This inverter can use 240v, and 120v at the same time?

You can use both 240V and 120V loads at the same time by connecting two cables to HOT1. However, please ensure that the 120V load does not exceed 50% of the inverter’s rated power, which is 6000W for 120V output.

What is the idle power consumption?

When the power saver is activated, idle consumption is 40W; with the power saver off, it’s 180W.
