1. Important Safety Information
WARNING! Before usin the Inverter, you need to read and save the safety instructions.
1-1. General Safety Precautions
1-1-1.Do not expose the Inverter to rain, snow, spray, bil e or dust. To reduce risk of hazard, do not cover or
obstruct the ventilation openin s. Do not install the Inverter in a zero-clearance compartment. Overheatin
may result. Allow at least 30CM of clearance around the inverter for air flow. Make sure that the air can
circulate freely around the unit. A minimum air flow of 145CFM is required.
1-1-2. To avoid risk of fire and electronic shock, make sure that existin wirin is in ood electrical
condition and that the wire is not undersized. Do not operate the Inverter with dama ed or substandard
wirin .
1-1-3. This equipment contains components which may produce arcs and/or sparks. To prevent fire and/or
explosion do not install in compartments containin batteries or flammable materials or in a location which
require i nition protected equipment. This includes any space containin asoline-powered machinery, fuel
tanks, or joints, fittin s, or other connection between components of the fuel system.
See Warranty for instructions on obtainin service.
1-1-4. Do not disassemble the Inverter/Char er. It contains no user-serviceable parts. Attemptin to service
the Inverter/Char er yourself may result in electrical shock or fire. Internal capacitors remain char ed after
all power is disconnected.
1-1-5. To reduce the risk of electrical shock, disconnect both AC and DC power from the Inverter/Char er
before attemptin any maintenance or cleanin . Turnin off controls will not reduce this risk
CAUTION: Equipment damage
The output side of the inverter’s AC wirin should at no time be connected to public power or a enerator.
This condition is far worse than a short circuit. If the unit survives this condition, it will shut down until
corrections are made.
Installation should ensure that the inverter’s AC output is, at no time, connected to its AC input.
Warning: Limitations On Use
SPECIFICALLY NOTE THAT THE GLOBAL LF INVERTER/CHARGER SHOULD NOT BE USED IN
CONNECTION WITH LIFE SUPPORT SYSTEMS OR OTHER MEDICAL EQUIPMENT OR DEVICES.
1-2. Precautions When Working with Batteries
1-2-1. If battery acid contacts skin or clothin , wash immediately with soap and water. If acid enters eye,
immediately flood eye with runnin cold water and et medical attention immediately.
1-2-2. Never smoke or allow a spark or flame in the vicinity of a battery or en ine.
1-2-3. Do not drop a metal tool on the battery. The resultin spark or short-circuit on the battery may cause
an explosion.
1-2-4. Remove personal metal items such as rin s, bracelets, necklaces, and watches when workin with a
lead-acid battery. A lead-acid battery produces a short-circuit current hi h enou h to weld a rin or the like
to metal, causin a severe burn.
1-2-5. To reduce the risk of injury, char e only deep-cycle lead acid, lead antimony, lead calcium el cell,
absorbed mat, or NiCad/NiFe type rechar eable batteries. Other types of batteries may burst, causin
personal injury and dama e.

2. Introduction
2-1. General Information
Global LF Series Pure Sine Wave Inverter is a combination of an inverter, battery char er and AC auto-
transfer switch into one complete system with a peak conversion efficiency of 88%.
It is packed with unique features and it is one of the most advanced inverter/char ers in the market today.
It features power factor corrected, sophisticated multi-sta e char in and pure sine wave output with
unprecedentedly hi h sur e capability to meet demandin power needs of inductive loads without
endan erin the equipment.
For the re ular model, when utility AC power cuts off(or falls out of acceptable ran e), the transfer relay is
de-ener ized and the load is automatically transferred to the Inverter output. Once the qualified AC utility is
restored, the relay is ener ized and the load is automatically reconnected to AC utility.
The Global LF Series Inverter is equipped with a powerful char er.
The overload capacity is 300% of continuous output for up to 20 seconds to reliably support tools and
equipment lon er
Another important feature is that the inverter can be easily customized to Battery priority via a DIP switch,
this helps to extract maximum power from the battery in renewable ener y systems.
Thus, the Global LF Series Pure Sine Wave Inverter is suitable for Renewable ener y systems, Utility, RV,
Marine and Emer ency appliances.
To et the most out of the power inverter, it must be installed, used and maintained properly. Please read the
instructions in this manual before installin and operatin .

2.5 Electrical Performance
2. .1 Invert
Topology
The Global LF inverter/char er is built accordin to the followin topolo y.
Invert: Full Brid e Topolo y.
Char e: Isolate Boost Topolo y
Because of hi h efficiency Mosfets and 16bit, 4.9MHZ microprocessor and heavy transformers, it outputs
PURE SINE WAVE AC with an avera e THD of 15% (min 5%, max 25%) dependin of load connected and
the battery volta e.
The peak efficiency of the Global LF series is 88%.
Overload Capacity
The Global LF series inverters have hi h overload capacities, makin it ideal to handle demandin loads.
1 For 110%<Load<125%(±10%), no audible alarm for 14 minutes, beeps 0.5s every 1s in the 15th minute,
and Fault(Turn off) after the 15th minute.
2 For 125%<Load<150%(±10%), beeps 0.5s every 1s and Fault(Turn off) after 1 minute.
3 For 300% Load>150%(±10%), beeps 0.5s every 1s and Fault(Turn off) after 20s.≧
Caution:
After the inverter is switched on, it takes a finite time for it to self dia nose and et ready to deliver full
power. Hence, always switch on the load(s) after a few seconds of switchin on the inverter. Avoid switchin
on the inverter with the load already switched on. This may prematurely tri er the overload protection.
When a load is switched on, it may require initial hi her power sur e to start. Hence, if multiple loads are
bein powered, they should be switched on one by one so that the inverter is not overloaded by the hi her
startin sur e if all the loads are switched on at once.
2. .2 AC Charger

AIMS Power www.aimscorp.net
Global LF Series is equipped with an active PFC (Power Factor Corrected) multista e battery char er. The
PFC feature is used to control the amount of power used to char e the batteries in order to obtain a power
factor as close as possible to 1.
Unlike other inverters whose max char in current decreases accordin to the input AC volta e, Global LF
series char er is able to output max current as lon as the input AC volta e is in the ran e of 164-
243VAC(95-127VAC for 120V model), and AC freq is in the ran e of 48-54Hz(58-64Hz for 60Hz model).
The Global LF series inverter has a very rapid char e current available, and the max char e current can be
adjusted from 0%-100% via a liner switch to the ri ht of the battery type selector. This will be helpful if you
are usin our powerful char er on a small capacity battery bank. Fortunately, the liner switch can effectively
reduce the max char in current to 20% of its peak.
Choosin “0” in the battery type selector will disable the char in function.
Caution:
Pls turn the charge current control switch gently to avoid breakage due to over-turning.
There are 3 char in sta es:
Bulk Charging: This is the initial sta e of char in . While Bulk Char in , the char er supplies the battery
with controlled constant current. The char er will remain in Bulk char e until the Absorption char e volta e
(determined by the Battery Type selection) is achieved.
A software timer will measure the time from A/C start until the battery char er reaches 0.3V below the boost
volta e, then take this time asT0 and T0×10 = T1.
Absorb Charging: This is the second char in sta e and be ins after the absorb volta e has been reached.
Absorb Char in provides the batteries with a constant volta e and reduces the DC char in current in order
to maintain the absorb volta e settin .
In this period, the inverter will start a T1 timer; the char er will keep the boost volta e in Boost CV mode
until the T1 timer has run out. Then drop the volta e down to the float volta e. The timer has a minimum
time of 1 hour and a maximum time of 12 hours.
Float Charging: The third char in sta e occurs at the end of the Absorb Char in time. While Float
char in , the char e volta e is reduced to the float char e volta e (determined by the Battery Type
selection*). In this sta e, the batteries are kept fully char ed and ready if needed by the inverter.
If the A/C is reconnected or the battery volta e drops below 12Vdc/24Vdc, the char er will restart the above
cycle.
If the char e maintains the float state for 10 days, the char er will deliberately reset the cycle to protect the
battery.

De-sulphation
The de-sulphation cycle, switch position 8, is marked in red because this is a very dan erous settin if you
do not know what you are doin . Before attemptin to use this cycle you must clearly understand what it
does and when and how you would use it.
What causes sulphation? This can occur with infrequent use of the batteries, or if the batteries have been
dischar ed so low that they will not accept a char e. This cycle is a very hi h volta e char e cycle desi ned
to try to break down the sulphated crust that is preventin the plates from takin a char e and thus allow the
plates to clean up and accept a char e once a ain.
Charging depleted batteries
The Global LF series inverter allows start up and throu h power with depleted batteries.
For 12VDC models: after the battery volta e oes below 10V and the power switch is kept in the "ON"

position and the inverter stays connected to the battery and the battery volta e doesn’t drop below 2V, the
inverter will be able to char e the battery once qualified AC inputs are present.
Before the battery volta e oes below 9VDC, the char in can be activated when the switch is turned to
“Off”, then to “ON”.
When the volta e oes below 9VDC, and you accidently turn the switch to OFF or disconnect the inverter
from the battery, the inverter will not be able to char e the battery once a ain, because the CPU loses
memory durin this process.

The char in capacity will o to peak char e rate in about 3 seconds. This may cause a enerator to drop
frequency, makin the inverter transfer to battery mode.
It is su ested to radually put the char in load on the enerator by switchin the char in switch from
min to max. To ether with the 15s switch delay our inverter ives the enerator enou h time to spin up.
This will depend on the size of the enerator and rate of char e.
2. .3 Transfer
While in the Standby Mode, the AC input is continually monitored. Whenever AC power falls below the
VAC Trip volta e (154 VAC, default settin for 230VAC,90VAC for 120VAC), the inverter automatically
transfers back to the Invert Mode with minimum interruption to your appliances - as lon as the inverter is
turned on. The transfer from Standby mode to Inverter mode occurs in approximately 10 milliseconds. And
it is the same time from Inverter mode to Standby mode.
Thou h it is not desi ned as a computer UPS system, this transfer time is usually fast enou h to keep your
equipment powered up.
There is a 15-second delay from the time the inverter senses that continuously qualified AC is present at the
10
