Quick Overview

The RD1824 Provides Reliable Off-Grid Power from Magnum Energy


The 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.


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.


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:

1. simply connect the inverter’s output to your distribution circuits or electrical panel.

2.connect your power cable (AC) to the inverter’s easy-toreach terminal block.

3. connect the batteries.

4. and switch on the power.
