Calculating Size of DC Input Cables for XPower 1750 Plus

Refer to Table 3-3to plan the DC cabling:

•Keep all cables as short as possible, and ensure that each cable between the inverter and the battery is no longer than 6 feet (1.8 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.
