OutBack Skybox SBX5048 Hybrid Inverter

5000W Backup Power at 120/240VAC

OutBack Power has been making reliable and long-lasting inverters for on and off grid for many years.  The SkyBox hybrid grid tie inverter can be used as a grid-tie inverter with or without a battery. The SkyBox combines the inverter and the charge controller, MATE and extra components of the Radian and FLEXmax inverters into one easy to install box.

Instead of having many strings of panels, the SkyBox can accept 2 strings with up to 600 volts per string. This is similar to other grid intertie inverters, however, the SkyBox also has the ability to use a 48 volt battery. In addition, the Skybox can interface with a generator for added versatility.

The SkyBox gives a digital representation of a sine wave with many steps that your most sensitive electronic devices would not be able to differentiate the SkyBox AC from the grid.

When used with a battery, the SkyBox SBX5048 can be used to enhance self-supply of solar energy. This is useful when net-metering, or grid feed is not available, or when you want to add a battery at a later date. This system uses DC coupling for both the solar and the connection to the battery system for greater overall efficiency. The SkyBox uses any commonly available 48 VDC battery bank, any lead type, flooded, AGM, or gel, and many Lithium batteries. PV input voltage range is 250-600 VDC, allowing longer PV strings. Compliant with California rule 21 and Hawaii 14H grid support requirements.

The system features backup power; grid support; net metering; non-export; and prioritized charging from renewables. These features can use any of the loads in the house, including those on the main service panel, what we call “primary” self-supply. Backup power is available to the loads connected to the backup loads panel, with a quick transfer time of 20ms. Backup power capacity is 5 kW. The inverter has ground fault and arc fault protection built in. CT’s can be installed on the house AC lines for export control. 5 year warranty.
