Installation
Determine Battery Capacity
Battery type and battery size strongly affect the performance of the
PROwatt SW. 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.
For a list of Xantrex Battery Chargers, go to www.xantrex.com or
contact Customer Service (see “Contact Information” on page i of
this guide).
Choose A Location
CAUTION: Risk of inverter damage.
The PROwatt SW must only be connected to a battery that
has a nominal output of 12 volts. The PROwatt SW 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 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 shock.
Do not install the PROwatt SW 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 in a
zero-clearance compartment. Overheating may result.
