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
7

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"
9

AIMS Power www.aimscorp.net
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

AIMS Power www.aimscorp.net
input terminals to when the transfer is made. This delay is built in to provide time for a enerator to spin-up
to a stable volta e and avoid relay chatterin . The inverter will not transfer to enerator until it has locked
onto the enerator’s output. This delay is also desi ned to avoid frequent switchin when input utility is
unstable.
2. .4 Auto Frequency Adjust
The inverter is desi ned with Auto Frequency adjust function.
The factory default confi uration for 220/230/240VAC inverter is 50Hz, and 60Hz for 100/110/120VAC
inverter.
If the output frequency needs to be chan ed this is done by puttin in a valid input Power Source to the
inverter’s input lines. Once the inverter validates the input, the output will automatically chan e.
NOTE: The inverter will output factory set freq after it restarts. Customers who can only accept one freq
should specify the freq when orderin .
2. . Power Saver
There are 2 different workin statuses for our Global LF
inverter: “Power On” and “Power Off”.
When the power switch is in “Unit Off” position, the inverter
is powered off.
When the power switch is turned to either of “Power Saver
Auto” or “Power Saver Off”, the inverter is powered on.
Power saver function is desi ned to conserve battery power
when AC power is not or rarely required by the loads.
In this mode, the inverter pulses the AC output lookin for an
AC load (i.e., electrical appliance). Whenever an AC load
( reater than 25 watts) is turned on, the inverter reco nizes the need for power and automatically starts
invertin and output oes to full volta e. When there is no load (or less than 25 watts) detected, the inverter
automatically oes back into search mode to minimize ener y consumption from the battery bank.
In “Power saver on” mode, the inverter will draw power mainly in sensin moments, thus the idle
consumption is si nificantly reduced.
The inverter is factory defaulted to detect a load for 250ms every 30 seconds. This cycle can be customized
to 3 seconds thru SW3 on the DIP switch.
Power saver on Power saver off Power saver on(Load detected)
Note: The minimum power of a load to take inverter out of sleep mode (Power Saver On) is 25 Watts.

The Global LF Series is desi ned with extraordinarily low idle power consumption which is only a mere
0.8-1.8% of its rated power.

When in the search sense mode, the reen power LED will blink and the inverter will make a tickin sound.
At full output volta e, the reen power LED will li ht steadily and the inverter will make a steady hummin
sound. When the inverter is used as an “uninterruptible” power supply the search sense mode or “Power
Saver On” function should be defeated.
Exceptions
Some devices when scanned by the load sensor cannot be detected. Small fluorescent li hts are the most
common example. (Try alterin the plu polarity by turnin the plu over.) Some computers and
sophisticated electronics have power supplies that do not present a load until line volta e is available. When
this occurs, each unit waits for the other to be in. To drive these loads either a small companion load must
12

AIMS Power www.aimscorp.net
be used to brin the inverter out of its search mode, or the inverter may be pro rammed to remain at full
output volta e (Power On mode).
2. .6 Protections
The Global LF series inverter is equipped with extensive protections a ainst various harsh situations/faults.
These protections include:
AC Input over volta e protection/AC Input low volta e protection
Low battery alarm/Hi h battery alarm
Over temperature protection/Over load protection
Short Circuit protection (1s after fault)
Back feedin protection
When Over temperature /Over load occur, after the fault is cleared, the master switch has to be reset to
restart the inverter.
The Low battery volta e trip point can be customized from a defaulted value of 10VDC to 10.5VDC thru
SW1 on the DIP switch.
The inverter will o to Over temp protection when the heat sink temp. ≥105ºC(221 ), and o to Fault℉
(shutdown Output) after 30 seconds. The switch has to be reset to activate the inverter.
The Global LF series Inverter has back feedin protection which avoids presentin an AC volta e on the AC
input terminal in Invert mode.
After the reason for the fault is cleared, the inverter has to be reset to start workin .
2. .7 Remote Control
Apart from the switch panel on the front (or top) of the inverter, an extra switch panel connected to the RJ11
port at the DC side of the inverter thru a standard telephone cable can also control the operation of the
inverter (sold separately Part # PICGLFREMOTE).
If an extra switch panel is connected to the inverter via “remote control port”, to ether with the panel on the
inverter case, the two panels will be connected and operated in parallel.
Whichever first switches from “Off” to “Power saver off” or “Power saver on”, it will power the inverter
on.
If the commands from the two panels conflict, the inverter will operate accordin to the followin priority:
Power saver on> Power saver off> Power off
Only when both panels are turned to the “Unit Off” position, will the inverter be powered off.
The Max len th of the cable is 10 meters.
WARNING
Never cut the telephone cable when the cable is attached to inverter and battery is connected to the inverter.
Even if the inverter is turned off, it will dama e the remote PCB inside if the cable is short circuited durin
cuttin .

2. .10 FAN Operation
For 1-3KW models, there is one multiple controlled DC fan which starts to work accordin to the below
lo ic.
For 4-6KW models, there is one multiple controlled DC fan and one AC fan. The DC fan will work in the
same way as the 1-3KW models, while the AC fan will work once there is AC output from the inverter.
So when the inverter is in power saver mode, the AC fan will work from time to time in response to the
pulse sent by the inverter in power saver mode.
The Operation of the DC fan at the DC terminal side is controlled by the followin lo ic:

2. .11 DIP Switches
On the DC end of inverter, there are 4 DIP switches which enable users to customize the performance of the
device.
Switch NO Switch Function Position: 0 Position: 1
SW1 Low Battery Trip Volt 10.0VDC 10.5VDC
*2 for 24VDC, *4 for 48VDC
SW2(230V) AC Input Ran e 184-253VAC 154-264VAC(40Hz+)
SW2(120V) AC Input Ran e 100-135VAC 90-135VAC(40Hz+)
SW3 Load Sensin Cycle 30 seconds 3 seconds
SW4 Battery/AC Priority Utility Priority Battery Priority
Low Battery Trip Volt:
Deep dischar e of the lead acid battery leads to hi h losses in capacity and early a in . In different
applications a different low volta e disconnection level is preferred. For example, for solar applications,
user may intend to have less DOD to prolon the battery life cycle. While for mobile applications users may
intend to have more DOD to reduce battery capacity and on board wei ht.
For 12VDC models, the Low Battery Trip Volt is set at 10.0VDC by default. It can be customized to
10.5VDC usin SW1. This is to prevent batteries from over-dischar in while there is only a small load
applied on the inverter.
*2 for 24VDC, *4 for 48VDC
AC Input Range:
There are different acceptable AC input ran es for different kinds of loads.
For some relatively sensitive electronic devices, a narrow input ran e of 184-253VAC (100-135V for
120VAC model) is required to protect them.
While for some resistive loads which work in a wide volta e ran e, the input AC ran e can be customized to
154-264VAC (90-135V for 120VAC model), this helps to power loads with the most AC input power
without frequent switches to the battery bank.
In order to make the inverter accept dirty power from a enerator, when the SW2 is switched to position “1”,
the inverter will bypass an AC input with a wider volta e and frequency (40Hz plus for 50Hz/60Hz).
Accordin ly, the AC char er will also work in a wider volta e and freq ran e (43Hz plus for 50Hz/60Hz).

This will avoid frequent switches between battery and enerator. But some sensitive loads will suffer from
the low quality power.
The pros and cons should be clearly realized.
Load Sensing Cycle:
The inverter is factory defaulted to detect load for 250ms every 30 seconds. This cycle can be customized to
3 seconds throu h SW3 on the DIP switch.
AC/Battery Priority:
Our inverter is desi ned with AC priority by default. This means, when AC input is present, the battery will
be char ed first, and the inverter will transfer the input AC to power the load. Only when the AC input is
stable for a continuous period of 15 days will the inverter start a battery invertin cycle to protect the
battery. After 1 normal char in cycle ac throu h put will be restored.
The AC Priority and Battery Priority switch is SW4. When you choose battery priority, the inverter will
invert from battery despite the AC input. Only when the battery volta e reaches the low volta e alarm
point(10.5V for 12V) will the inverter transfer to AC Input, char e battery, and switch back to battery when
the battery is fully char ed. This function is mainly for wind/solar systems usin utility power as back up.
Note: In battery priority mode, when qualified AC inputs for the first time, the inverter will only go into
battery priority mode after a cycle of bulk charging and absorb charging is finished. The inverter will not
go into float charging mode.
2. .12 Other Features
Battery voltage recovery start
After low battery volta e shut off (10V for 12V model or 20V for 24V model or 40V for 48V model), the
inverter is able to restore operation after the battery volta e recovers to 13V/26V/52V (with power switch
still in the “On” position). This function helps to save the users extra labor to reactivate the inverter when
the low battery volta e returns to an acceptable ran e in renewable ener y systems. The built in battery
char er will automatically reactivate as soon as city/ enerator ac has been stable for 15 seconds.
WARNING
Never leave the loads unattended, some loads (like a Heater) may cause accidents in such cases.
It is better to shut everythin off after low volta e trip than to leave your load on, due to the risk of fire.
Auto Gen Start
The inverter can be customized to start up a enerator when the battery volta e oes low.
When the inverter oes to low battery alarm, it can send a si nal to start a enerator, and turn the enerator
off after battery char in is finished.
The auto en start feature will only work with enerators desi ned to work with this feature. There is an
open/close relay that will short circuit the positive and ne ative cable from a enerator. The input DC
volta e can vary, but the Max current the relay can carry is 16Amp.
