Calculating Cable Sizes for
XPower 1200 Plus
To operate safely and effectively, the
XPower 1200 Plus
needs proper
cables and fuses. Because the
XPower 1200 Plus
has low-voltage and
high-current input, it is essential that you use low-resistance wiring
between the battery and the inverter to deliver the maximum amount of
usable energy to your load.
For safe and efficient operation, you will need to calculate cable sizes for
your:
•
DC input cables from the battery to inverter (one way)
•
Chassis ground cable from the grounding point to the chassis ground
screw on the inverter’s DC panel.
See
Figure 3-3, “DC Panel Connections (XPower 1750 Plus shown)” on
page 3–14
.
Calculating Size of DC Input Cables for
XPower 1200 Plus
Refer to
Table 3-1
to plan the DC input cabling for your particular
application:
•
Keep all cables as short as possible, and ensure that each cable
between the inverter and the battery is no longer than 5 feet (1.5 m).
•
Do not use aluminum cable. It has about 1/3 more resistance than
copper cable of the same size, and it is difficult to make good, low-
resistance connections to aluminum wire.
•
Xantrex recommends that you use oil resistant cable.
WARNING: Fire Hazard
Never use a cable longer than 5 feet (1.5 meters). A cable longer than 5
feet (1.5 meters) can potentially generate enough heat to start a fire or
result in poor inverter performance.
