BATTERY SAFETY INFORMATION
• Always wear eye protection, such as safety glasses, when working with batteries.
• Remove all jewelry before working with batteries.
• Never work alone. Have someone assist you with the installation or be close
enough to come to your aid when working with batteries.
• Always use proper lifting techniques when handling batteries.
• Always use identical types of batteries.
• Never install old or untested batteries. Check each battery’s date code or label
to ensure age and type.
• Batteries are temperature sensitive. For optimum performance, they should be
installed in a stable temperature environment.
• Batteries should be installed in a well-vented area to prevent the possible
buildup of explosive gasses. If the batteries are installed inside an enclosure,
vent its highest point to the outdoors.
• When installing batteries, allow at least 1 inch of air space between batteries to
promote cooling and ventilation.
• NEVER smoke in the vicinity of a battery or generator.
• Always connect the batteries first, then connect the cables to the inverter. This
will greatly reduce the chance of spark in the vicinity of the batteries.
• Use insulated tools when working with batteries.
• When connecting batteries, always verify proper voltage and polarity.
• Do not short-circuit battery cables. Fire or explosion can occur.
• In the event of exposure to battery electrolyte, wash the affected area with soap
and water. If acid enters the eyes, flood them with running cold water for at
least 15 minutes and get immediate medical attention.
• Always recycle old batteries. Contact your local recycling center for proper
disposal information.

1.0 Introduction
Thank you for purchasing the UX Series inverter/charger from Xantrex
Technology Inc. The UX inverter takes DC energy stored in a battery-bank and
converts it to usable AC power. The UX inverter/charger features an AC pass-
through circuit, powering home appliances from utility or generator power while
charging the batteries with its optional battery charger. When utility power fails,
the battery backup system keeps your appliances powered until utility power is
restored.
Internal protection circuits in the inverter prevent over-discharge of the batteries
by shutting down the inverter when low-battery conditions occur. When utility
or generator power is restored, the inverters with the battery charger option
installed 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.

1.0 Introduction
Features and Options
The UX Series inverter is an economical product designed to provide a reliable
supply of electricity to all the essential circuits of a home or business. Critical
loads can be powered for hours or days, depending on the size of the system
battery-bank. When connected to the utility grid, the optional battery charger
quickly recharges the batteries.
Standard Features
•Modified Sine Wave Power
The UX Series inverters provide a modified sinewave output which operates
most AC appliances and equipment.
•Simplicity
The UX Series is simple to operate. All inverter and optional battery charger
controls are located on the AC end panel.
•High Efficiency
The inverter operates at over 90% efficiency through most of its power range.
•Low Power Consumption
UX Series inverters use extremely low current while in the search mode,
consuming little more than one watt of power. In the ON mode, the inverter uses
less than 8 watts of power.
Options
The following options are available for the UX Series inverter:
•SB Option (Battery Charger/AC Transfer Relay)
The inverter can be equipped with a three-stage battery charger designed to
recharge typical, deep-cycle batteries.
The built-in, AC transfer relay automatically transfers power from the utility to
the inverter and handles 30 amps of current at 120 Vac (15 amps of current at
230 Vac).
•RC8/50
The RC8 allows the inverter to be switched ON or OFF remotely and includes an
LED status indicator.
•Battery Temperature Sensor
The battery temperature sensor (BTS) ensures proper charging of the batteries
based on temperature. Installing a BTS extends battery life by preventing
overcharging in warm temperatures and undercharging in cold temperatures.

2.0 System Configuration
Types of Applications
The UX Series inverter/charger can be configured for a wide variety of
applications.
• It can be configured for OFF-GRID (stand-alone) applications where no utility
power is available.
• It can be configured for ON-GRID applications where it can operate the AC loads
when the utility grid fails, and/or keep the batteries charged.
Types of Configurations
The UX series inverter is designed for either 120 Vac/60 Hz or 230 Vac/50 Hz
applications. In locations where there is a 230 Vac/50 Hz requirement, “E” models
are available.
120 Vac/60 Hz Models
These models produce 120 volts between HOT and NEUTRAL which is standard
for North America.
230 Vac/50 Hz Models
These models produce 230 volts between HOT (Line) and NEUTRAL which is
standard for most locations except North America.
Battery-Bank Requirements
The inverter system can only support loads for the duration of their battery-bank
capacity. Battery-bank pre-planning is essential.
See Appendix B, Batteries, for additional information on battery types and
estimating battery-bank sizing.
Pre-Configuration Planning
Comprehensive pre-planning is recommended before installing the system to
ensure all factors are accounted for.
Pre-planning should include (but is not limited to) the following.
1. What are the total watts required for all anticipated loads?
2. What are the voltage requirements for the anticipated loads?
(120 Vac or 230 Vac)
3. Battery-bank type, size, and configuration?
4. Are there any local or national electrical codes that need to be met?
5. Are there any special permits required for this installation?
NOTE: It is not possible to use an “E”
model inverter to power
120/240 Vac/60 Hz loads.

2.0 System Configuration
Off-Grid Applications
The UX inverter can be used to support off-grid, stand-alone systems where no
utility power is available. Using the UX inverter in an off-grid application
include:
• renewable energy systems (without the SB Option on the inverter),
• renewable energy systems with generator backup (with the SB Option on the
inverter), and
• generator-only systems (with and without the SB Option on the inverter).
Renewable Energy Systems
In this configuration, the main power is generated by renewable energy sources,
such as solar, wind, or hydro-generators and is stored directly in a battery-bank.
The UX inverter will invert the DC power stored in the battery-bank into AC
power to operate the AC loads. The SB Option is not required for this
application.
See Figure 2-1 for an illustration of a renewable energy application without
the SB Option installed on the UX Inverter.
This illustration includes the optional accessories such as remote monitoring
options and a variety of renewable energy sources. Disregard any part of this
illustration that does not apply to the system configuration being installed.

2.0 System Configuration
Renewable Energy Systems with Optional Generator Backup
In the event that renewable energy sources are insufficient to power the required
loads or keep the batteries charged, a generator can be used to supplement the
system. The SB Option is required on the inverter for this application. The SB
Option provides a pass-through relay that allows power from the generator to
pass through the inverter to either support the AC loads and/or charge the
batteries.
See Figure 2-2 for an illustration of a renewable energy application with the
SB Option installed on the UX Inverter.
This illustration includes the optional generator backup as well as illustrates
the utilization of the optional accessories such as remote monitoring options
and a variety of renewable energy sources. Disregard any part of this
illustration that does not apply to the system configuration being installed.
See page 20 for additional information regarding generator configurations.
