Installation Codes
Governing installation codes vary depending on the location and type of
installation. Electrical installations must meet local and/or national wiring
codes and should be performed by a qualified electrician.
An example of a national wiring code is the US National Electrical Code
(NEC, NFPA70) article 551 governing electrical installations in RVs. In
other geographical regions or for other applications, other codes will
apply. It is the installer's responsibility to identify and apply all
applicable codes.
Calculating Battery Requirements
Battery type and battery size strongly affect the performance of the
inverter. Therefore, you must 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. We recommend that you purchase
as much battery capacity as possible.
For information on calculating battery capacity, go to www.xantrex.com,
click Support, select the Xpower Inverters product, and then click Go.
Under Calculators & Problem Solvers, click Battery Calculator.
CAUTION: Equipment damage
The inverter must only be connected to a 12 V battery system. It will not operate
if connected to a 6 V battery and will be damaged if connected to a 24 V battery.
Choosing an Effective Charging System
The charging system must be appropriate for your particular installation.
A well-designed charging system ensures 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 information about choosing an effective battery charging system, go
to www.xantrex.com, click Support, select the Xpower Battery
Chargers product, and then click Go. Under Tech Notes & How-To's,
click Selecting the Right Battery Charger.
NOTE: If the main charging source will be the vehicle's alternator, then
its voltage and current ratings must be appropriate for the size and type of
battery that is selected.
