This inverter is also available pre-wired with appropriate safety components onto a Four Star Solar Power Center with Magnum Energy or Midnite Solar mounting panels

The Magnum Energy MS4448 120/240V Series Inverter/Charger is a pure sine wave inverter designed specifically for the most demanding renewable energy applications. The MS-AE Series is powerful, easy-to-use, and best of all cost effective. 

No stacking required: The unique design of the MS-AE Series can provide 120 or 240 volt output in one unit, eliminating the need to stack two units together to get 240 volts. 

Power Factor Corrected (PFC): The PFC charger is built into all of the inverter/chargers. It uses less energy from a generator than a standard charger, using only 15 amps per 100 amps versus 23 amps used by standard chargers. 

Safe and reliable: The MS-AE Series is ETL Listed to the stringent requirements of UL 1741 for renewable energy installations. 

Easy-to-install: Install the MS-AE Series in four easy steps: simply connect the inverter's output to your distribution circuits or electrical panel, connect your utility power cable (AC) to the inverter's easy-to-reach terminal block, connect the batteries, and switch on the power.

About Magnum Energy

When Xantrex bought Trace, a few of their key people started Magnum Energy. Established in 2002 in Everett, Washington, Magnum Energy went on to make great strides in the renewable energy field with their high-quality inverters.
A company that doesn't just rest on their brand name, Magnum Energy's research and development team is constantly pushing the boundaries of inverter technology. They pioneered the technology behind power factor corrected battery chargers, which is in each and every one of their inverters. This innovation is the most efficient way to charge batteries. Magnum Inverters save you the time, money and hassle it takes to gas up your generators. Another nice feature of Magnum Energy inverters (whether they are 120 VAC or 240 VAC) is that they can accept 120 or 240 VAC power input to help charge the batteries without the use of a transformer.
Magnum Energy has also made advances with AC Coupling, which allows a solar power grid-tie system to work with a backup battery system that can be charged even during grid black outs. This is a perfect add-on for folks who want to include a battery back-up package to their pre-existing grid-tie system. Read more about AC coupling here.
Magnum Energy inverters are also good-looking, safe, easy-to-use and American-made. Wholesale Solar was one of the first renewable energy companies to distribute Magnum Energy. We carry all Magnum Energy Inverters for RV, Marine, or Back-up power. We have also have teamed up with Magnum Energy to create to power centers called the Mini-Magnum Power Centers. The MS4024PAE and the MS4448PAE Power Centers are perfect for offgrid living or AC coupling with a grid-tied system anywhere.
