The AC/battery priority switch, denoted as SW5, operates in AC priority mode where, upon utility AC power loss, the transfer relay is disengaged, seamlessly shifting the load to the inverter output. Upon AC utility restoration, the relay reengages, automatically transferring the load back to AC utility. For solar setups, opting for battery priority is recommended.
The High-Capacity Low-Frequency Off-Grid Inverter is a versatile unit that integrates the functionalities of an inverter and a battery charger to deliver seamless power backup solutions.
The large-capacity inverter features a direct-connect terminal block, enabling users to exceed the 18,000 watt capacity and utilize its 300% surge power (up to 54,000 watts for 20 seconds, as mentioned earlier). It serves as emergency backup power for residences, businesses, and extensive off-grid applications.
It is also ideal for off-grid systems or using AC power supplies for home power emergencies. This ensures uninterrupted power supply during power failures. The system can detect power loss and seamlessly switch to draw power from a connected battery bank, ensuring continuous power supply.
Another widely embraced use of this inverter is in RV and vehicle customization, including illuminating lights and operating appliances in an off-grid cabin. Additionally, it can supply power to a mobile business or office and facilitate camping equipment operations. It stands out as the optimal choice for robust power systems.
