Reliable Off-Grid and Backup Power from Magnum Energy

Magnum Energy RD Inverter/Charger, off-grid inverter, backup power inverterThe RD Series Inverter/Charger from Magnum Energy is a new generation inverter designed specifically for renewable energy use. The RD Series is powerful, easy-to-use, and best of all, cost effective. Features include an easy access wiring compartment, four stage temperature compensated battery charger, dual input 50 amp transfer, die cast aluminum base with an aluminum cover for optimum high temperature performance.

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.
