Introduction
Thank you for purchasing the DR Inverter/Charger from Xantrex Technology Inc.
The DR Inverter is one of the finest inverter/chargers on the market today,
incorporating state-of-the-art technology and high reliability.
The inverter features an AC pass-through circuit, powering your home appliances
from utility or generator power while charging the batteries. When utility power
fails, the battery backup system keeps your appliances powered until utility power
is restored. Internal protection circuits prevent over-discharge of the batteries by
shutting down the inverter when a low battery condition occurs. When utility or
generator power is restored, the inverter transfers to the AC source and recharges
the batteries.
The front panel features LEDs for reading system status, and controls to
customize the inverter settings for your battery bank.
The DR Inverter is an economical product designed to provide a reliable supply of
electricity to all the essential circuits in the home or business during a power
outage. The critical loads can be powered for hours or days, depending on the size
of the system battery bank. When utility grid power returns, the batteries are
quickly recharged to ensure they will be ready to supply backup power during the
next outage.
Accessories allow the DR Series to also serve as a central hub of a renewable
energy system.
Modified Sine
Wave Pow er
The DR Inverter provide a modified sine wave output which operates most AC
appliances and equipment.
Battery Charger/AC
Transfer Relay
The inverter/charger includes a 3-stage battery charger designed to recharge any
type of battery in the shortest possible time. The built-in, fully automatic AC
transfer relay automatically transfers power from the utility to the inverter and
handles a full 60 amps of current at 120 Vac (30 amps for pass-through plus
20 to 30 amps for charging - depending on the model).
Simplicity The DR Inverter is simple to operate. All inverter and battery charger controls are
located on the front panel.
High Efficiency The inverter/charger operates at over 90% efficiency through most of its power
range in Invert-mode.
Low Power
Consumption
DR Inverter use extremely low current while in the search mode, consuming less
than 1 watt of power. In the ON mode, the inverter/charger uses less than 12 watts
of power.
