Introduction

Key Features

The Freedom SW Inverter/Charger is a true sine wave inverter/charger that can be used for mobile, marine and commercial applications. The Freedom SW Inverter/Chargers are designed to operate with a wide variety of generators and are capable of operating in parallel with a generator for short durations to assist with starting large loads. The Freedom SW is a convenient combination of an inverter, multistage battery charger, and transfer switch in one electronic device.

•As an inverter, the Freedom SW provides true sine wave power for your microwave, entertainment system, computer, and other loads. This power is identical to the AC source provided from the utility grid (power company).

•Some of the benefits of true sine wave power include consistent cooking in your microwave, handling of sensitive loads such as your TV set, dimmer switches, and appliances with speed controls.

•Highly versatile platform capable of series stacking for 120/240V line configurations and parallel stacking to increase power levels.

•High efficiency true sine wave output to power sensitive electrical and electronic equipment.

•Surge capacity to start difficult loads like well pumps, refrigerators, or A/C compressors.

•Power factor-corrected (PFC) input minimizes AC input current required for charging, increasing AC pass-through capacity.

•As a charger, it has high output, multi-stage charging capability minimizing charging time.

•Capable of operating from 50Hz and 60Hz power source by extending AC qualification frequency range. See “ACIn Settings” on page 52.

IMPORTANT: Dual Line models require only the Line 1 Input to be energized in order to qualify AC. Line 2 Input does not have to be powered in a single phase system.

•Temperature-controlled, variable-speed internal cooling fans. The fans turn on when the internal temperature reaches 45 °C (113 °F) and reaches maximum speed at 70 °C (158 °F). The fan turns off when the internal temperature falls to 40 °C (104 °F).

•Designed with efficient field serviceability in mind.

•The Freedom SW Inverter/Charger is also Xanbus-enabled which allows network compatibility and communication with other Xanbus- enabled devices. See more information under “System Components” on page 6.

Key Features Explained

Built-in Charge Formulas For the unit to perform at the highest level, the batteries must be charged correctly. The Freedom SW has optimized algorithms for flooded, gel, and AGM batteries.

Battery Temperature Sensor Since battery temperature is a key factor in correct charging, the charging formula must be adjusted (automatically and in real time) according to the actual battery temperature to ensure that batteries are fully charged, but not overcharged. For this reason, a battery temperature sensor is included with your Freedom SW and has temperature compensated the charge formula.
