I-P-SPC Series LowFrequency Solar Power Inverter with Built-in SolarCharge Controller 4000W



1)Highquality low frequency pure sine wave inverter(with utility charge functionand UPS function)

2)Built-in PWMsolar power charge controller



1)Off-grid solar power system

2) Utility and solar complementarypower generation system


1) Easy toinstall. To configure a solar system, users just need to connect it with solarpanels and batteries.

2)CPUmanagement,Intelligent control,modular design

3)LEDsLCD display. LCD can display various parameters(such as the output voltage, frequency,working mode)

4)Multifunctiondesign, AVR UPS function. Users don’t need to buy solar, controller, AC chargeror stabilizer.

5) External battery connection, it’sconvenient for users to expand use time and back-up power time

6)Withsuper load-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. It can drive almost any kinds ofload

7)Lowfrequency pure sine wave circuit design, stable quality, easy to maintenance, lowfailure rate and long service life (underproper operation, it can last atleast 5 years)

8) Perfectprotection: low voltage protection, high voltage protection, over temperature protection,short-circuit protection, overload protection

9)CE / EMC / LVD/ RoHS /FCC approvals

10)2 years warranty, life-long technicalsupport



Off-grid solarpower system

1.   When connected withbattery and AC loads,users can set it to normal working mode or sleep mode. 


1.1 Normal workingmode:FREQUENCY in the LCD display is set to01. No matter it’s connected AC loads or not, theinverter always convert DC to AC. 

It’sready to supply power to the AC loads. In this mode, the LCD will displayoutput voltage as 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 power consumption of theinverter is only 1-6W. The LCD shows the output voltage 0. If the power of theconnected loads is over 5%,then the inverter will automatically convert DC toAC to supply power for the loads within 5s. The LCD shows the output voltage.As shown below:


Kindly note:

1) Only the solar panel charges thebattery

2) Off-grid solar power system. Itis suitable for areas that are lack of utility or plentiful solar


Utility andsolar complementary power generation system

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 standby mode.

2.1.Utilityfirst (AC first) battery standby mode : FREQUENCY in the LCD display is set to 01.When utility and battery are connected to the inverter, utility will supplypower to the loads prior. When utility is cut off, the battery willautomatically continue to supply power via power inverter.

   Stepsare as follows:

   Step1: When utility is available, it will drive the loads directly after voltagebeing stabilized and at the same time charge batteries via power inverter .

   Step2: When utility is cut off, the inverter will convert DC to AC automatically toensure uninterrupted power supply within 5ms.

   Step3: When utility is available again, inverter will automatically transfer toutility supplying power to loads and charge batteries via power inverter at thesame time.

See Workflowas below.

LCDdisplayed as bellow:


Kindly note:

1) There are 2 ways to charge thebattery, utility and solar panel

2) This system is suitable for powersystems built in areas that are lack of utility. Or people can use solar andutility at the same time.

2.2. Batteryfirst (DC first)utility standy mode: FREQUENCY in the LCD display is set as 03. When utility andbattery are connected to the inverter, battery will supply power to the loadsprior to utility. When battery capacity is not enough, utility will continue tosupply power automatically.

Steps are as follows:

Step1: When battery is available, it will drive the AC loads via power inverter.

Step2: When battery does not have enough power, it will automatically transfer toutility supplying power to the loads

Step3: After the battery is fully charged (e.g. by solar or wind chargecontroller), it will automatically transfer to battery supplying power to theloads via power inverter.

See Workflowas below.


LCDdisplayed as bellow:



1) There is only one way to charge thebattery: solar panel

2) This system is suitable for areas whereelectricity is expensive or environmental areas where solar power can be fullyused to save utility bill.such as home solar&wind system,streetlightsolar&wind system
