Outback Radian GS4048A-01 4,000 Watt Advanced Inverter/Charger


NOTE: The OutBack Power Radian inverter is not designed for use in mobile applications and will void the manufacturer’s warranty. If you need a large mobile system, it can be custom built as a power panel that will give you similar power output and functionality to a Radian system. If you have any questions or would like to discuss building a mobile power panel, please email us or give us a call.

NOTE: This is the new GS4048A-01 model which replaced the GS4048A. It's the same inverter but also conforms to the new UL 1741 SA as defined in California's Rule 21. This inverter qualifies to be installed anywhere in the United States, including California and Hawaii. You can read more about this in the OutBack Power Product Change Notice.

This is the Radian Advanced. The main difference between the standard Radian and the advanced Radian is that the advanced model can charge a wider variety of battery types. It also has more advanced diagnostics and a superior energy management program.

The Radian series is the newest inverter from Outback Power. Unlike other Outback models, the Radian is capable of 120/240 volts AC output using just a single unit. While you can combine up to 10 Radian inverters in parallel for 40,000 watts, it's not necessary to use more than one Radian if your power consumption is less than 4,000 watts. If you plan to parallel multiple units for more power, a HUB4 or HUB10 communications manager is necessary. The Radian Advanced is only available in a 48 volt DC input.

These units are referred to as grid-interactive. It can be used as a standard grid-tie inverter and offset your utility bill or it can work as an off-grid system. In the event that you lose utility power, the Radian will take over by keeping your house powered. The length of time you will have backup power will depend upon the storage capacity of your battery bank. If you have a generator, the Radian's built-in charger can be used to keep your batteries full. If inclement weather prevents your solar array from charging your batteries, a generator can save the day (and your batteries).

When used in conjunction with the GSLC load center, installation is fast and easy. Generally, the installation can be completed by the home owner. However, be sure to check with your local electrical inspector and utility company for local laws and regulations when connecting to the grid. Some jurisdictions require grid-interactive inverters to be installed by licensed electricians.
