Connecting Cables (not included)
Power wire and wiring are very important to the

performance of the inverter. Because the inverter has a
low voltage, high current input, low resistance wiring is

essential between the battery and inverter. This is so it

can deliver the maximum amount of energy to the load.

NOTE
Use double cables for a full 2500 Watt load.
Use only copper wire. Aluminum wire has about one-third

more resistance than copper wire of the same size, plus
it is difficult to make good, low-resistance connections to
aluminum wire.
We recommend #4 AWG copper cable (90°C insulation
rating) as the minimum size for connections between
the battery and inverter.
Keep the cable length as short as possible, no more
than four feet (one and a half meters). This will keep the
voltage drop to a minimum.
If the cable has too much voltage drop, the inverter may
shut down when drawing higher currents because voltage

at the inverter may drop below 10 volts. If you must use
longer cables, choose thicker cables, such as #2 AWG.
To connect the cables between the
inverter and the battery:
1. Press the Power Button on the inverter to the off
position. If the power source is a DC power supply,
switch it off as well.

It is a good idea to check and tighten these screws
from time to time. They can become loose by vibrations
or thermal cycling.
