Freedom X
1200 Less than 5 feet
(1.5 meters)
No. 2 AWG 150 A DC
NOTE :It is not recommended using a cable longer than 5 feet
(1.5 meters) in each direction. North American cable sizes above
are based on the US National Electrical Code Table 310.17 -
75 °C cables, assuming an ambient temperature of 30
° C cables.
Table 6 Required Cable Sizes
IMPORTANT : Using the correct cable size is critical to achieving
the rated performance of the Freedom X 1200 unit. When starting
a heavy load the Freedom X 1200 can draw current surges from
the battery of up to 400A. If the DC wiring is too small the voltage
drop from this surge will result in a voltage at the Freedom X 1200
terminals that is too low for the Freedom X 1200 to operate
correctly. The Freedom X 1200 may appear to operate correctly
with smaller cables until a heavy load such as a microwave or
refrigerator attempts to start - then the unit may work correctly
sometimes and not work correctly other times.
DC Disconnects and Over-Current Devices
The DC circuit from the battery to the Freedom X 1200 must be
equipped with a disconnect and over-current device. This usually
consists of a circuit breaker, a “fused-disconnect”, or a separate
fuse and DC disconnect.
Do not confuse AC circuit breakers
with DC circuit breakers. They are not interchangeable. The
rating of the fuse or breaker must be matched to the size of cables
used in accordance with the applicable installation codes. The
breaker or disconnect and fuse should be located as close as
possible to the battery, in the positive cable. Applicable codes
may limit how far the protection can be from the battery.
Batteries
The Freedom X 1200 uses 12-volt battery banks. Every Freedom
X 1200 system is recommended to have a deep-cycle battery
(house) or group of batteries with a total capacity of 100 Ah or
more which provides the DC current that the Freedom X 1200
converts to AC.
