The Magnum Energy MS4448PAE Inverter/Charger is a pure sinewave inverter designed specifically for the most demanding renewable energy applications. The unique design of the MS4448PAE provides two 120VAC output lines that are 180° out-of-phase with each other, so that the combination of the L1 and L2 lines total 240VAC and the voltage between either L1 or L2 and neutral is 120VAC, eliminating the need to purchase two units and stack them together to get 240 volts.

When the power requirements of the system are beyond the capacity of a single MS-PAE Series inverter or the system is expanded as more loads are added, up to four MS-PAE Series inverters can be connected together in a parallel configuration. When connecting inverters in parallel, the overall inverter power and surge capacity is increased to power a large single load or more smaller loads. You can parallel up to four inverter/chargers for up to 17.6kw of power at 120/240V. The MMP and ME-RTR are required for parallel stacking the MS-PAE Series.

Also available in 4000 (24 volts), the MS-PAE Series inverters are powerful, easy-to-use and ETL listed to the stringent requirements of UL 1741 and CSA C22.2 No. 107.1-01 for Renewable Energy installations.

Magnum Energy offers a 3-year warranty on this inverter and a 5-year warranty when you install it with a MMP or MP Magnum Energy panel.

About Magnum

Key Points:

  • Innovation makes ME inverters the most efficient way to charge batteries.
  • Batteries can be charged without the use of a transformer whether they accept 120 VAC or 240 VAC input.

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.
