Also, longer and/or thinner cables will reduce the efficiency of the
overall system, since excessive power will be dissipated in the cabling.
For temporary operation at
reduced power levels, the
guidelines listed in Table 1 may
be followed, or you can use the
cable sizes in Table 6.
Ideally, the cables should be no
more than 4 ft (1.5m) long. See
table 2 for a pictorial
representation of the wire
gauges.
Strip approximately 1/2” (1.25cm) of insulation from the ends of the
cables being connected to the inverter. Attach 5/16” ring terminals
to the ends of the wires to be attached to the DC terminals on the
Portawattz 3000. The ring terminals should be crimped with a proper
crimping tool.
Another option is to use Ilsco, or equivalent, box-lug terminals
(available at electrical parts suppliers). The bare cable end can then
be inserted into the lug terminal.
The other ends of the cables, which are connected to the power
source, must be terminated with lugs or other connectors that allow
a secure, low resistance connection to be made to the power source.
For instance, if the power source is a battery, the cables must be
terminated with battery terminals that clamp to the posts on the
battery.

A solid, low resistance connection to the DC power
source is essential for proper operation.
CAUTION!
DO NOT operate your inverter for more than 5 minutes or at a higher power
using these cable sizes. Refer to table 6.
