1. Product Description

500W solar UPS is anew generation of integrative solar product. It represents our company’s latesthigh technology and with below features:

1) Integrative design(grid power, solar controller, inverter in one box), simple structure and process.

2) Wide workingvoltage range for voltage unstable area.

3) Low price &high performance.

4) External batterydesign provide more choice to user for different capacity, and also easy forreplacing.

5) Comprehensivecircuit protection design, with short-circuit protection, over-load protection,over-charging protection, over-discharging protection.

2. Product Structure

Back Side:

1) AC Input Socket (AC INPUT): This socket can beconnected to grid power. There is a 10Afuse inside of this socket, and it will break down when a serious fault occurs.This product has UPS functions: loading consume grid power when grid power ison, and when grid power off, it will switch to inverter supply powerautomatically within 20ms.

2) AC Output Socket (AC OUTPUT): supply power toAC appliances or devices.

3) FAN: on the middle of back side. It startsworking automatically when working temperature over 50, and stopsworking when temperature lower than 45.

Front Side:

1) Inverter Switch (POWER): This product startsworking when turn on this switch.

2) Positive Pole of Battery Input Terminal (BAT+): Red color, for positive pole of 12Vstorage battery.

3) Negative Pole of Battery Input Terminal (BAT-): Black color, for negative pole of12V storage battery.

4) Grid Power Working Indicator (AC PASS): Whenthere is grid power, this indicator is on, the grid power provides electricityto battery and loading devices. In this case, the inverter stops working.

5) Inverter Working Indicator (INVERT): Whengrid power off, this indicator is on, the inverter starts working and providespower to loading devices automatically.

6) DC5V Output Socket (USB 5V): DC 5V output,max current 2A, mainlyfor mobile devices charging.

7) DC12V Output Socket (DC OUTPUT): DC 12Voutput, mainly for 12V devices, such as DC LED light, DC energy saving light,DC TV, DC fan, DC electric blanket, etc.

8) Battery Energy Indicating (3pcsLED indicators): When all three lights on, more than 2/3 dump energy; when twolights on, dump energy more than 1/3 but less than 2/3; when only one light on,dump energy less than 1/3; when all three lights off, battery energy will beused up soon, battery needs charging immediately. When battery under charging,three lights keep shinning alternately.
