The Ms Series Inverter / Charger from Magnum Energy is a pure sine wave inverter designed specifically for rugged mobile applications. See the details tab for more information.

The Ms Series is powerful, easy-to-use, and best of all, cost effective. These Magnum inverters are ETL Listed to the stringent requirements of UL/cUL 458 and CSA C22.2 #107.1-01, ensuring that the inverters are safe and reliable. All models also meet KKK-A-1822E standards for emergency vehicle use. The MS2012-20B 2000 watt inverter charger can be installed in four easy steps: simply connect the inverter's output to your distribution circuits or electrical panel, connect your shore power cable (AC) to the inverter's easy-to-reach terminal block, connect the batteries, and switch on the power. This unit comes equipped with a 100 amp Power Factor Corrected charger, conformal coating on the PC boards, stainless steel fastners and a transfer relay with 2 legs at 30 A for 120v/30a or 240 v/60 a service.

  • Power Factor Corrected (PFC) Charger: Our PFC charger is built into all of our inverter / chargers. It uses less energy from a generator than a standard charger - using 25-30% less AC current than standard chargers.
  • Versatile mounting: Mount the MS2012-20B on a shelf, bulkhead, or even upside down
  • The lightweight aluminum base and cover also provides noise reduction and corrosion resistance.
  • Multiple ports, including an RS485 communication port for network expansion, and a remote port.
  • Accessible design: The extra large AC access cover with terminal screw block and 360 degrees DC connection terminals with covers make this inverter more accessible when it needs to be.
  • Convenient switches: This unit comes with an on/off inverter-mounted switch with an easy-to-read LED indicator.
  • The MS2012-20B is backed by a three-year (36-month) limited warranty and a five year limited warranty when installed on an MMP or MP system.
