10)2 years 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 to 01. No matterit’s connected AC loads or not, the inverter always convert DC to AC.  It’s ready to supply power to the AC loads. Inthis mode, the LCD will display output voltage as bellow:

1.2 Sleep mode：FREQUNCY in the LCD display is set as 02.Ifthe power of the connected AC loads is lower than 5% of the inverter’s ratedpower, there will be no output from the inverter. Only the chip of inverter isworking. The power consumption of the inverter is only 1-6W. The LCD shows theoutput voltage 0. If the power of the connected loads is over 5%,then theinverter will automatically convert DC to AC to supply power for the loadswithin 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. It issuitable 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.

   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.

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:

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.

Kindly note:

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
