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 HF unit. When starting a heavy load the Freedom

 

HF 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

 

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

 

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

 

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

 

current that the Freedom HF converts to AC.

1000, 1800 specifications

Xantrex Technology offers a range of power inverters that cater to both recreational and professional needs, with the Xantrex 1800 and 1000 models being among the most popular in their lineup. These inverters are specially designed to convert DC power from batteries into clean, pure sine wave AC power, making them suitable for running sensitive electronic devices and appliances.

The Xantrex 1800 is a robust inverter that delivers 1800 watts of continuous power and 3600 watts of peak power. This makes it ideal for powering essential appliances like refrigerators, microwaves, and power tools. Its compact design allows for easier installation in various settings such as RVs, boats, and off-grid homes.

On the other hand, the Xantrex 1000 inverter is designed for lower power requirements, offering 1000 watts of continuous power and 2000 watts of peak power. It is perfect for powering small appliances, electronics, and gadgets, making it a great choice for weekend campers and those who require less energy capacity.

Both models feature advanced technologies, including low idle power draw, which ensures that energy is conserved when the inverter is not actively powering devices. They also include overload protection, ensuring the inverter shuts down automatically if the power exceeds its limits, thus preventing damage to the unit or connected devices.

Another hallmark of Xantrex inverters is their user-friendly interface. The LED indicator lights provide clear status updates on the power output and inverter operation, making it easy for users to monitor performance at a glance. Additionally, both models feature various safety protocols, including short circuit and over-temperature protection, to enhance operational safety.

Installation is straightforward, thanks to the provided mounting options and wiring accessories. The units are designed to withstand harsh environments, with durable casings that enhance longevity and resilience.

In summary, the Xantrex 1800 and 1000 models offer reliable power solutions for a variety of applications. Their combination of high-quality sine wave output, advanced safety features, and user-friendly operation makes them a top choice for anyone seeking dependable off-grid power. With Xantrex, users can trust that they are investing in products engineered for performance and durability in an ever-increasing range of power needs.
