  • Easy-to-install: Install the RD Series in four easy steps: simply connect the inverter’s output to your distribution circuits or electrical panel, connect your power cable (AC) to the inverter’s easy-to-reach terminal block, connect the batteries, and switch on the power.
  • Choices: The RD Series comes in four power models and 12 and 24 volt models, allowing you to choose the model that is right for you.
  • Versatile mounting: Mount the RD Series on a shelf or on a wall.
  • Lightweight: The lightweight aluminum base and cover also provides noise reduction and corrosion resistance.
  • Multiple ports: The RD 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 RD Series comes with an on/ off inverter-mounted switch with an easy-to-read LED indicator.
  • Expanded transfer relay: 60 Amp transfer service is available on all models.
