5.4 Permanent Installation
A permanent installation is highly recommended if you will be using
your PORTAWATTZ 400 frequently to power electrical products of
more than 150 Watts. Read this entire section completely before
purchasing any supplies or beginning the installation.
DC Cable Selection and Preparation
Correct cable size and wiring is very important for safe operation and
maximum performance of the PORTAWATTZ 400. Because the
PORTAWATTZ 400 is designed for low voltage, high current input,
low resistance cable from the battery to the DC terminals is needed to
deliver the maximum amount of usable energy. Undersized cable
will diminish battery and inverter performance.
Use copper wire rather than aluminum. Aluminum wire has 1/3 more
resistance than copper wire of the same size and good, low resistance
connections are more difficult to achieve.
For cable runs between the battery and inverter of 4 ft. or less use #8
AWG copper cable. For wire runs of 4 ft. to 12 ft. use #6 AWG
copper cable. The insulation on the cable should be rated at 90ºC
(minimum). Using undersized cable, or when the battery to inverter
run is greater than 12 ft., may result in excessive voltage drop
between the battery and PORTAWATTZ 400 and cause the inverter to
prematurely shut down.
As a general rule, select a cable size that is heavier than
the minimum required for your installation. A heavier
cable will reduce the voltage drop from the battery to the
inverter and provide greater run time.
Securely attach a M5 or larger ring type terminal to the end of each
cable that will be connected to the PORTAWATTZ 400’s DC
terminals. The end of each cable that is connected to the battery must
be fitted with a terminal ring that is secured to the post on the battery.
A solid, low resistance connection to the battery is essential for
proper operation of the PORTAWATTZ 400.
IMPORTANT! Installation of a 50 Amp Class T fuse or 50 Amp
circuit breaker on the cable that runs from the positive DC Input
Terminal on the PORTAWATTZ 400 to the positive battery post
is recommended. Install the fuse or circuit breaker near the
end of the cable that is connected to the battery, following
installation instructions provided by its manufacturer. Make sure
the fuse or circuit breaker selected has an interrupt rating of at
least 10 times the amp hour rating of the battery (or batteries).
