SOLAR BATTERY BACK-UP USER’S MANUAL

Design for solar fountain pump

Item No.: Aquajet-Pro-Kit-24V-Battery

1. OVERVIEW

1) This special solar battery back-up is designed specifically for solar fountain pump. It can store solar energy for day or night use.

2) The input power should be from a solar module or DC power supply with an output voltage of 18V.

3) The battery back-up has build-in functions of overcharging and over discharging protection.

4) There is a bicolor LED light indicating the working status of the battery back-up. Green shows the battery is in normal operating status, while red shows the battery is in low voltage status, which requires the battery to be recharged.

5) Timing function is added to the battery back-up to decrease the energy consumption in cloudy days or winter. The pump works 10 minutes every hour if the timing function is enabled by placing the timer switch to “Timer On” position.

6) To get different pump performances, the output voltage can be adjusted in the range of 12V-24V through the potentiometer.

2. ASSEMBLING & OPERATION

[pic]

1) Loosen the screws on the underside of the housing and remove the cover from the battery box.

2) Place the electrical connector on the red (brown) cable onto the positive terminal of the rechargeable battery. See the figure above.

3) Place the cover back on the battery box and tighten the screws.

4) Connect the “Input” cable of the battery back-up to a solar module or a DC power supply, and tighten the protection screw if applicable.

5) Insert the pump plug to the “Output” socket of the battery back-up, and also tighten the protection screw.

6) Make sure to keep the pump fully underwater when it operates.

7) Turn the “On/Off” switch on the battery to the “ON” position, then the “G-normal/R-low” status LED on the battery shows green and the solar pump starts to operate. The pump may not work and the status LED may show red when the battery operates for the first time, since the battery may lose its energy in the inventory. It just needs to be charged for 2 to 3 hours in the sunshine by facing the solar panel towards the sun, then the status LED shows green and the pump starts to work.

8) The pump will automatically stop running while the battery is discharged to its low voltage limit, and the status LED shows red in the meantime.

9) The “G-normal/R-low” status LED stays in red before the battery is recharged to its starting voltage. After recharged to its starting voltage, the battery shall continue to be charged for an extra half hour with the status LED flashing red-green twice every 10 seconds. Then the pump automatically operates and the status LED shows green again.

10) The “Timer on/Timer off” switch switches the pump running mode between "intermittent mode" and "continuous mode". In the “intermittent mode” (i.e., “Timer On”), a build-in timer is enabled to run the pump 10 minutes per hour to save the energy, and it is especially useful in winter or on cloudy days. In the "continuous mode" mode, the build in timer is disabled and the pump shall run continuously.

11) If you want the pump to have longer operating time in the evenings or on cloudy days, then turn the ”On/Off” switch to “Off” position during the day time and turn it to “On” position whenever you need.

Note:

*Item 1) , 2) and 3) apply only to first time use of the battery，please also refer to the special menu for first time use.

*The battery will always be charged in the sunlight no matter whether the switch has been turned to “On” or “Off”! And the system will automatically cut off the charging current while the battery is charged to its high voltage limit (fully charged).

* Adjusting the potentiometer of battery backup to reach a higher output voltage will get a better performance, however it will shorten the total pump operating time as the larger the working voltage of the pump is, the more power the pump will consume.

3. CAUTIONS

1) Do not charge the solar battery back-up by any AC power supply directly; it is designed ONLY for DC power.

2) Do not leave this battery back-up in bad ambient environment.

3) Do not leave the battery back-up in direct blazing sunlight or expose it to extremes of heat or cold, which can affect its service life. If possible place the battery in the shadow of the solar panel or your house or even a tree etc.

4) Do not dip this battery back-up into water.

4. TROUBLE SHOOTING

If the status LED shows red always and the pump does not operate even though the solar module is in full sunlight, please check the possible failures below:

1) No connection to the solar module—check connection to the solar module.

2) Check if the “Timer On/Off” switch is on. Please note in this mode the pump runs intermittently, i.e., 10 minutes per hour to save the energy.

3) Please turn off the “On/Off” switch of battery backup to keep the pump staying in non-working mode. Then charge the battery backup in direct sunlight for two days. When it's charged fully, turn on the “On/Off” switch to run the pump.

4) The battery is out of its service life and needs to be replaced. Alternatively you may bypass the battery backup and connect the solar panel directly to the pump, i.e., the pump will be driven directly by the solar panel.

Replace the battery by following the steps shown in the right photos:
