Note: Xantrex recommends not using a cable longer than 5 feet (1.5 meters) in each direction. Cable sizes above are based on the US National Electrical Code Table 310.17 - 75C cables, assuming an ambient temperature of 30 °C cables.

 

Important: Using the correct cable size is critical to achieving the rated

 

performance of the Freedom HW unit. When starting a heavy load the Freedom

 

HW 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

 

HW terminals that is too low for the Freedom HW to operate correctly. The

 

Freedom HW 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

The DC circuit from the battery to the Freedom HW must be equipped

and Over-

with a disconnect and over-current device. This usually consists of a

Current Devices

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 HW uses 12-volt battery banks. Every Freedom HW system

 

requires a deep-cycle battery or group of batteries that provide the DC

 

current that the Freedom HW converts to AC.
