This full sine wave power inverter was designed with top quality and durability in mind and is built to survive 10+ years in the harshest conditions . Our full sine wave 18KW inverter works with very little power loss, outputs an average THD of 3% , its idle consumption is 270 watts, and its peak DC to AC efficiency is notably 90%
The AC/battery priority switch is SW5. In AC priority mode, when utility AC power cuts off, the transfer relay is de-energized and the load is automatically transferred to the inverter output. Once the AC utility is restored, the relay is energized and the load is automatically transferred to AC utility. For solar systems, it is better to choose battery priority.
The Big Power Low Frequency Off Grid Solar Inverter is a multi-function inverter, combining functions of inverter, solar charger controller and battery charger to offer uninterruptible power support. the solar controller is Max 80A and 145V Input,You can disable the inbuilt solar controller, connect with external solar controller, or use for other systems (it is not limited for solar system)
The big power inverter has is the direct-connect terminal block, which allows users to surpass the 18,000 watt capacity and harness its 300% surge power (up to 54,000 watts for 20 seconds as previously noted). it is emergency backup power for residences, businesses and large off grid applications.
It is also perfect for off grid system or use AC power supply for home power emergencies, which can keep the power supply uninterrupted in the event of an power failure. It can detect the loss of power and switch over to get power form a connected battery bank seamlessly to keep the power supply constant.
Our Solar inverters are also instrumental when it comes to solar energy harvesting and increasing the system efficiency. When the solar panels produce electric energy, the electric current flows to the solar inverter. The inverter then converts the DC into AC. From the inverter, the AC energy is ready for use to power the various appliances.
Another popular application of this inverter is for RV and vehicle upfitting applications, such as powering lights and other appliances in an off-grid cabin. It also can provide electricity for a mobile business or mobile office, and running camping equipment. it is the best choice for your big power system.
