Sungoldpower 6000W 48V   inverter is built for the purpose of running the whole house(small home), business office or large RV, which is perfect for using with renewable solar and using as an off-grid home and business back up power supply. The single phase inverter requires 120VAC input and can provide 120VAC output power for the appliances.

This inverter charger is built with UPS function to provide uninterrupted power to run household electric devices. The solar inverter comes with an internal transfer switch, so you don’t have to do anything when the power goes out. All the devices you have selected will be connected to the back-up power source automatically. In fact, you will not even notice that the power cut happened.

★ It is built-in 50 amp battery charger uses AC power, from the grid or from a generator, to recharge different kinds of battery bank.
★ Built-in solar controller, Maximum solar input voltage 145V, Maximum solar input current 60A, can also connect with external controller.
★ Low Frequency Inverter, High Quality, your best choice for your 48V home system.

 It is 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 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. 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.

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 6KW inverter works with very little power loss, outputs an average THD of 3%. Its built-in battery charger can use AC power from the grid or from a generator, to recharge different kinds of battery bank. 

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.

This power inverter has the direct-connect terminal block, which allows users to surpass the 6,000 watt capacity and harness its 300% surge power (up to 18,000 watts for 20 seconds as previously noted). It can effective power your electronic devices, household appliance and power tools, especially the tools and appliances with startup surges, such as refrigerator, freezer, microwave.

The 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 60A and 145V Input. You can disable the inbuilt solar controller, and connect to a larger external solar controller, or use for other systems (it is not limited for solar system).

The 6000w 48v inverter charger is a reliable power source for continuous backup applications. In inverter mode, DC power from the battery can be converted to AC power to power home appliances when a blackout in utility grid or when driving in mobile applications. It can also be a battery charger, which can convert the input AC power into DC power to charge the battery.
