Basic Installation Procedures

 

 

AC shore power

A source of 120 V, 60Hz sine wave alternating current is needed to

 

provide energy to charge batteries and pass power through to AC loads.

 

This source is usually the utility grid (power company) or an AC

 

generator. An automatic or manual AC source selector switch can be used

 

to switch between the multiple sources of shore power to the Freedom HF

 

system.

 

The AC source feeding the Freedom HF must have the neutral conductor

 

bonded to ground. When the inverter passes shore power through, it will

 

lift the bonding relay on the output and will rely on the input being

 

bonded in order to ensure that the power delivered to a sub panel is

 

properly bonded. See “AC Output Neutral Bonding” on page 1–9 for

 

more information on bonding relay operation.

 

 

 

Important: Throughout this manual, the term “shore power” refers to AC

 

input power from a utility grid, generator, or other AC source.

Generator

The Freedom HF is compatible with most generators which produce

 

nominal 120 Vac 60Hz sine wave AC power.

 

Since the DC charging current limit of the Freedom HF may be

 

configured to provide as little as 2A it is possible to use very small

 

generators with the Freedom HF to charge batteries. The Freedom HF has

 

been tested with generators of various sizes, including some as small as

 

700W.

AC Disconnect

Most safety requirements and electrical codes require the Freedom HF’s

and Over-

AC and DC inputs and outputs to be provided with over-current

Current

protection (such as circuit breakers or fuses) and disconnect devices.

Protection

 

Device

 

 

AC Input: The circuit breaker or fuse (connected through hard

 

wiring) that is used to supply the Freedom HF must be rated at no

 

more than 30A and must be approved for use on 120 Vac branch

 

circuits. The wire used between the breaker and the Freedom HF

 

input must be sized adequately to carry current up to the rating of the

 

input breaker and in accordance with the electrical codes or

 

regulations applicable to your installation.

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.
