Installation
Determine Battery Capacity
Battery type and battery size strongly affect the performance of the
PROwatt SW Inverter. Therefore, you need to identify the type of
loads your inverter will be powering and how much you will be
using them between charges. Once you know how much power you
will be using, you can determine how much battery capacity you
need. Xantrex recommends that you purchase as much battery
capacity as possible.
Determine A Charging System
The charging system must be appropriate for your particular
installation. A well-designed charging system will ensure that
power is available when you need it and that your batteries remain
in top condition. Inadequate charging will degrade system
performance and the wrong type of charger will reduce battery life.

contact Customer Service (see “Contact Information” on page i of
this guide).

CAUTION: Risk of inverter damage.
The PROwatt SW Inverter must only be connected to a
battery that has a nominal output of 12 volts. The PROwatt
SW Inverter will:
• Not operate if connected to a 6 volt battery and
• Be damaged if connected to a 24 volt battery.
CAUTION: Risk of inverter damage.
The PROwatt SW Inverter contains components that tend
to produce arcs or sparks. To prevent fire or explosion, do
not install the inverter in compartments containing
batteries or flammable materials or in locations that
require ignition-protected equipment.
WARNING: Risk of electrical shock.
Do not install the PROwatt SW Inverter in a wet
environment or in any other environment where moisture
can occur and enter the inverter enclosure through the
ventilation openings. This unit is not intended for marine
applications.
WARNING
To reduce the risk of fire, do not cover or obstruct the
ventilation openings. Do not install the PROwatt SW
Inverter in a zero-clearance compartment. Overheating
may result.
