1.2 Precautions When Working with Batteries
1.2.1 If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye,
immediately flood eye with running cold water for at least 20 minutes and get medical attention
immediately.
1.2.2 Never smoke or allow a spark or flame in vicinity of battery or engine.
1.2.3 Do not drop a metal tool on the battery. The resulting spark or short-circuit on the battery of other
electrical part may cause an explosion.
1.2.4. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a
lead-acid battery. A lead-acid battery produces a short-circuit current high enough to weld a ring or the like
to metal, causing a severe burn.
1.2.5 To reduce the risk of injury, charge only rechargeable batteries such as deep-cycle lead acid, lead
antimony, lead calcium gel cell, absorbed mat, and NiCad/NiFe or Lithium battery. Other types of batteries
may burst, causing personal injury and damage.
2 Introduction
2.1 General Information
Thank you for purchasing the LP Series Pure Sine Wave Inverter/Charger.
The LP Series Pure Sine Wave Inverter/Charger is a transformer based inverter and battery charger with an
unprecedented conversion efficiency of 90%.
It features power factor corrected, sophisticated multi-stage charging control and pure sine wave output with
high surge capability to meet power needs of all sorts of demanding loads without putting the equipment at
risk.
In response to the increasing demand of more advanced battery charging, our engineering team equipped the
inverter with a Battery Temperature Sensing probe for increased charging precision.
The generous 300% surge capacity of 20 seconds makes it possible to support demanding inductive loads.
The AC/Battery priority, auto generator start functionality and optional built-in charger make it ideally
suitable to work in backup power or anti-idle applications.
When customized to Battery priority mode via a DIP switch, the inverter will extract maximum power from
external power sources and a minimal cycle of battery will be required. With the availability of auto
generator start, an electrical generator can be integrated into the system and started when the battery voltage
goes low.
With audible buzzer and remote LCD panel, the inverter gives the users comprehensive information of the
operation status, making it easier for maintenance and troubleshooting.
Thus the LP Series Pure Sine Wave Inverter/Charger is suitable for applications including renewable energy
systems, utility, truck, RV and emergency vehicles etc.
To get the most out of the power inverter, it must be installed, used and maintained properly. Please read the
instructions in this manual before installing and operating.

2.4 Electrical Performance
2.4.1 Invert
Topology
The LP series pure sine wave inverter/charger is built according to the following topology.
Invert: Full Bridge Topology.
Charge: Isolated Boost Topology
When operating in invert mode, the direct current (DC) that enters the inverter from the batteries is filtered
by a large input capacitor and switched “On” and “Off” by the Metal Oxide Silicon Field Effect Transistors
(MOSFET) at a rate of 50 Hz or 60Hz, and directed into the transformer which steps the voltage up to 120
volts. The unit has a 16bit, 4.9MHZ microprocessor to control the output voltage and frequency as the DC
input voltage and/or output load varies.
Because of high efficiency MOSFETs and the heavy transformers, it outputs PURE SINE WAVE AC.
The peak invert efficiency of LP series is 90%.
Overload Capacity
The LP series inverter/charger has different overload capacities, making it ideal to handle demanding loads.
1 For 110%<Load<125% (±10%), no audible alarm in 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 the 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 3-5 seconds for it to self diagnose and get ready to deliver full
power. Hence, always switch on the load(s) after a few seconds of switching on the inverter. Avoid
switching on the inverter with the load already switched on. This may prematurely trigger the overload
protection. When a load is switched on, it may require initial higher power surge to start. Hence, if multiple
loads are being powered, they should be switched on one by one so that the inverter is not overloaded by the
higher starting surge if all the loads are switched on at once.
2.4.2 AC Charger
The LP Series pure sine wave inverter/charger is equipped with an active PFC (Power Factor Corrected)
multistage battery charger. The PFC feature is used to control the amount of power used to charge the
batteries in order to obtain a power factor as close as possible to 1.
Unlike other inverters whose max charging current decreases according to the input AC voltage, LP series
pure sine wave inverter/charger is able to output max charge current as long as input AC voltage is in the
range of 95-127VAC, and AC freq is in the range of 48-54Hz(58-64Hz for 60Hz model).
The LP series pure sine wave inverter/charger has a very rapid charge current available, and the max charge
current can be adjusted from 0%-100% via a liner switch on the DC side of the inverter. This will be helpful
if this powerful charger apply charging on a small capacity battery bank.
Choosing “0” in the battery type selector will disable charging function.
There are three main charging stages:
Bulk Charging: This is the initial stage of charging. While Bulk Charging, the charger supplies the battery
with controlled constant current. The charger will remain in Bulk charge until the Absorption charge voltage
(determined by the Battery Type selection) is achieved.

Software timer will measure the time from charger start until the battery charger reaches 0.3V below the
boost voltage, then take this time as T0 and T0×10 = T1.
Absorb Charging: This is the second charging stage and begins after the absorb voltage has been reached.
Absorb Charging provides the batteries with a
constant voltage and reduces the DC charging
current in order to maintain the absorb voltage
setting.
In this period, the inverter will start a T1 timer; the
charger will keep the boost voltage in Boost CV
mode until the T1 timer has run out. Then drop the
voltage down to the float voltage. The timer has a
minimum time of 1 hour and a maximum time of 12
hours.
Float Charging: The third charging stage occurs at
the end of the Absorb Charging time. While Float
charging, the charge voltage is reduced to the float
charge voltage (determined by the Battery Type
selection*). In this stage, the batteries are kept fully
charged and ready if needed by the inverter.
If the A/C is reconnected or the battery voltage drops below 12Vdc, the charger will reset the cycle above.
If the charge maintains the float state for 10 days, the charger will deliberately reset the cycle to protect the
battery.
De-sulphation
The de-sulphation cycle on switch position 8 is marked in red because this is a very dangerous setting if you
do not know what you are doing. Before ever attempting to use this cycle you must clearly understand what
it does and when and how you would use it.
What causes sulphation? This occurs with infrequent use of the batteries, nor if the batteries have been left
discharged so low that they will not accept a charge. This cycle is a very high voltage charge cycle
especially designed to try to break down the sulphated crust that is preventing the plates from taking a
charge and thus allow the plates to clean up and accept a charge once again.
