Introduction

In DC/AC inversionmode, users can set this series of inverters to normal working mode or sleepmode. In utility mode, it has Auto Voltage Regulation (AVR) function, utilitycharging function (AC first model) and UPS function. This multifunctional lowfrequency pure sine wave inverter has the advantages of stable quality, strong load-carrying ability and long service life. It also can work in poor environment. It is the second generation of our low frequencypure sine wave inverter I-P-XD-series.

Features

1、pure sine waveoutput, full power

2、CPU control,intelligentcontrol,modular design

3、LCD display variousparameters

4、Multifunction design(AVR, UPS), extra charger is not needed and electric      appliances can be protected.

5、External battery connection, it’s convenientfor users to expand use time and back-up power time

6、With superload carrying ability and high load capacity, this series of  inverters can not only drive resistance load;but also various kinds of inductive loads, such as motor, air conditioner,electric drills, fluorescent lamp, gas lamp.

7、Low frequency circuit design, stable quality, low failure rate and longservice life (under proper operation,it can last at least 5 years)

8、Perfect protection: low voltage protection, highvoltage protection, over temperature protection, short-circuit protection,overload protection, alarm alert

9、CE / EMC / LVD/RoHS Approvals

10、Two years warranty, life-long technical support

Function 

1、DC to AC inversionfunction in inversion mode (only connected with batteries and loads) ,users canset it to normal working mode or sleep mode

1.1、Normal working mode：FREQUNCY in the LCDdisplay is set to 01. No matter it’s connected AC loads or not, the inverteralways convert DC to AC.  It’s ready tosupply power to the AC loads. In this mode, the LCD will display output voltageas bellow:

1.2、Sleep mode：FREQUNCYin the LCD display is set as 02.If the power of the connected AC loads is lowerthan 5% of the inverter’s rated power, there will be no output from theinverter. Only the chip of inverter is working. The powerconsumption of the inverter is only 1-6W. The LCD shows the output voltage 0. Ifthe power of the connected loads is over 5%,then the inverter willautomatically convert DC to AC to supply power for the loads within 5s. The LCDshows the output voltage. As shown below:
                                  Load’s power＜5% of inverter’srated power                 Load’spower＞5%of inverter’s rated power

2、UPSfunction  When the inverter is connectedto battery and utility, users can set it to utility first (AC first) batterystandby mode or battery first (DC first)utility standy mode.

2.1、Utility first (AC first) batterystandby mode : FREQUENCY in the LCD display is set to 01. When utility and batteryare connected to the inverter, utility will supply power to theloads prior. When utility is cut off, the battery will automatically continueto supply power via power inverter.

   Steps are as follows:

   Step 1: When utility is available, it will drivethe loads directly after voltage being stabilized and at the same time chargebatteries via power inverter .

   Step 2: When utility is cut off, theinverter will convert DC to AC automatically to ensure uninterrupted powersupply within 5ms.

   Step 3: When utility is available again,inverter will automatically transfer to utility supplying power to loads andcharge batteries via power inverter at the same time.

2.2、Battery first (DC first)utility standby UPS mode: FREQUENCYin the LCD display is set as 03. When utility and battery are connected to theinverter, battery will supply power to the loads prior to utility. When batterycapacity is not enough, utility will continue to supply power automatically.

Steps are as follows:

Step 1: When battery is available, it will drive the AC loadsvia power inverter.

Step 2: When battery does not have enough power, it willautomatically transfer to utility supplying power to the loads

Step 3: After the battery is fully charged (e.g. by solar orwind charge controller), it will automatically transfer to battery supplyingpower to the loads via power inverter.
