Reliable Off-Grid and Backup Power from Magnum Energy
Power Factor Corrected (PFC) Charger: The RD series of inverter/chargers use less energy from a generator than standard chargers – using 25-30% less AC current than standard chargers.
Safe and reliable: The RD Series is ETL Listed to the stringent requirements of UL 1741, ensuring that the inverter is safe and reliable.
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.
The RD Series Inverter / Charger
You asked and Magnum listened. The RD Series Inverter/Charger is loaded with features:
- 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 wall.
- Lightweight: The lightweight aluminum base and cover also provides noise reduction and corrosion resistance.
