  • Pure sine wave – Power your TVs, computers and other sensitive electronics without worry. The pure sine wave inverter and power factor corrected charger provide clean, reliable inverter power with low total harmonic distortion (THD) of less than 5%.
  • Choices – The MS-PAE Series comes in 24 and 48 volt configurations, allowing you to choose the model that is right for you.
  • Versatile mounting – Mount the MS-PAE Series on a shelf or wall.
  • Lightweight – The lightweight aluminum base and cover also provides noise reduction and corrosion resistance.
  • Multiple ports – The MS-PAE Series provides 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° DC connection terminals with covers make this inverter more accessible when it needs to be.
  • Convenient switches – The MS-PAE Series comes with an on/off inverter-mounted switch with an easy-to-read LED indicator.
