1. General

Information

The Global LF Series Pure Sine Wave Inverter Charger product line is a combination of an

inverter, battery charger and auto AC transfer switch in one unit and has a peak conversion

efficiency of 88%. It is packed with unique features and is one of the most advanced inverter

chargers on the market today. It features power factor correction, sophisticated multi-stage

charging and pure sine wave output with unprecedentedly high surge capability to meet

demanding power needs of inductive loads without damaging the equipment.

When utility AC power cuts off (or falls out of acceptable range), the transfer relay is de-energized and the

load is automatically transferred to Inverter mode. Once the qualified AC power is restored the relay is

reenergized and the load is automatically reconnected to AC bypass mode. NOTE THE BYPASS RATING

OF THE INVERTER (page 34) AND DO NOT EXCEED. DAMAGE MAY OCCUR

AND VOID

THE WARRANTY. The Global LF Series Inverter is equipped with a powerful four stage smart charger

and includes an auto generator start feature. The overload capacity of the inverter charger products is 300%

of continuous output for up to 20 seconds to reliably support tools and equipment. This is for inverter

mode only. You can NOT bypass the surge rating of the inverter. This may cause permanent damage to the

inverter.

Another important feature is the "Battery" priority setting via a DIP switch on the back of the inverter charger.

This helps to extract maximum power from the battery in renewable energy systems such as solar and wind.

The Global LF Series Pure Sine Wave Inverter is suitable for renewable energy systems in work trucks, RV,

marine and emergency appliances.

To get the most out of the power inverter, it must be operated and maintained properly. Please read the

instructions in this manual before installing and operating.
