2 Xantrex PROwatt™ SW International Sine Wave Inverter Owner’s Guide
Introduction
Ease of Use
Superior features and rugged durability have been combined with
extreme ease of use:
• The unit is compact, light weight, and easy to install.
• You can power loads directly from the AC receptacle
• Easy-to-read digital display on the front panel lets you monitor
system performance at a glance.
• The optional remote ON/OFF switch lets you control the
inverter from a convenient location—up to 7.6 m (25 feet)
away—while the inverter itself is mounted out of sight and
close to the batteries.
Comprehensive Protection
The PROwatt SW is equipped with numerous protection features to
guarantee safe and trouble-free operation:
Low battery voltage
alarm
Alerts you if the battery has become
discharged to 11 V or lower.
Low battery voltage
shutdown
Automatically shuts the inverter down if
the battery voltage drops below 10.5 V.
This feature protects the battery from
being completely discharged. Within 30
seconds, the unit recovers automatically
once the battery voltage reaches above
12 Vdc. After 30 seconds, the unit turns
itself off.
High battery voltage
shutdown
Shuts the inverter down automatically if
the input voltage rises to more than 15.5 V.
The unit recovers automatically once the
battery voltage falls below 15.5 Vdc.
AC output overload
alarm and shutdown
Alerts you as the inverter approaches the
overload threshold. Shuts the unit down
automatically if a short circuit occurs or if
the loads attached to the inverter exceed
the operating limits.
Over temperature
alarm and shutdown
Alerts you if the unit is becoming too
warm to operate. Turns the unit off if its
temperature rises above an acceptable
level. The unit recovers automatically once
the internal temperature cools down.
