SOLAR BATTERY BACK-UP USER’S MANUAL
Design for solar fountain pump
Item No.: Aquajet-Pro-Kit-9V-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 8V-9V.
3) The battery back-up has built-in functions of overcharging and over discharging
protection.
4) There is a bicolor LED light indicating the working status of the battery back-up. The
GREEN shows the battery is in normal operating status, while the 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 6V-9V through the potentiometer.

ASSEMBLING & OPERATION
1)
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 the 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 place the pump fully underwater when the pump operates.
7)
Turn the “On/Off” switch on the battery to the “ON” position. The bicolor status LED 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 limit voltage, and the status LED
shows red in the meantime.
9)
The 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
