The Refurbished MMS1012 Inverter

The Magnum Energy MMS-1012 and MMS-1012G pure sine wave inverters are designed to provide cost effective solutions for mobile applications such as entertainment systems, small appliances, RVs and boats. They are versatile, easy-to-use, lightweight and would work as a reliable base for your energy system. Both MMS models are 1000-watt inverter/chargers with 20 amp AC transfer capability and a 50 amp, 4-stage Power Factor Correction (PFC) charger. They feature isolated input/output neutrals for mobile applications and a 15’ battery temperature sensor.

The difference between the MMS-1012 and the MMS 1012G is in the wiring
. With the MMS-1012, the AC input and output are provided with pigtail wires to allow hardwiring to a main AC distribution panel and to an inverter sub-panel. The MMS-1012-G's AC input is provided by a standard 3 ft. plug-in power cord, and the AC output is provided by a standard GFCI two plug outlet.

Based on the popular ME and MS Series inverters, the MMS is smaller, lighter and less expensive while retaining all the built-in protection and reliability of ME and MS models. The MMS charger uses a PFC (Power Factor Corrected) charger, which is 85% efficient and the same charger topology used in all Magnum models. The MMS Series is also ETL Listed to the stringent requirements of UL/cUL 458, CSA C22.2 #107.1-01 and meets the KKK-A-822E standard.

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.
