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

10) 2years warranty, life-long technicalsupport

Function

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 thesolar panel charges the battery

2) Off-gridsolar power system. It is suitable for areas that are lack of utility orplentiful solar

Utility and solar complementarypower 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.Utility first (AC first) battery standby mode: FREQUENCY in the LCD display is set to 01. When utility and battery areconnected to the inverter, utility will supply power to the loads prior. Whenutility is cut off, the battery will automatically continue to supply power viapower 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.

See Workflow as below.

Kindly note:

1) There are 2 ways to charge the battery, utility and solarpanel

2) This system is suitable for power systems built in areas thatare lack of utility. Or people can use solar and utility 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.

Stepsare 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 will automaticallytransfer 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.

Kindlynote:

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

2) This system is suitable for areas where electricity isexpensive or environmental areas where solar power can be fully used to save utilitybill.such as home solar&wind system,streetlight solar&wind system
