Designing Your Installation
Before doing anything else, determine how you are going to use your
PROwatt 3000, and on the basis of that, design a power system that will
give you maximum performance. The more thorough your planning, the
better your power needs will be met. In particular, you need to:
• Calculate your battery requirements
• Choose an effective charging system
Calculating Battery Requirements
Battery type and battery size strongly affect the performance of the
PROwatt 3000. 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.
Consult Appendix B, “Battery Types and Sizes” for a detailed explanation
of how to determine the appropriate number and size of batteries for your
needs.
Choosing 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.
Consult Appendix C, “Alternators and Charging Systems” for
information about designing an effective charging system.
CAUTION
The PROwatt 3000 must only be connected to a battery that has
a nominal output of 12 volts. It will not operate if connected to a
6 volt battery and will be damaged if connected to a 24 volt
battery.
