SOLAR BATTERY BACK-UP USER’S MANUAL
Design for solar fountain pump
Item No.: Aquajet-Pro-Kit-24V-Battery
1. OVERVIEW
) 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.
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 0 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
2V-24V through the potentiometer.
2. ASSEMBLING & OPERATION
) 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 m y not work nd the st tus LED m y show red
when the b ttery oper tes for the first time, since the b ttery m y lose its energy in the inventory. It just
needs to be ch rged for 2 to 3 hours in the sunshine by f cing the sol r p nel tow rds the sun, then the
st tus LED shows green nd the pump st rts 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 0 seconds. Then the pump automatically operates and the status LED shows green again.
0) 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 0 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.
) 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) nd 3) pply only to first time use of the b ttery ，ple se lso refer to the speci l menu for first time
use.
*The b ttery will lw ys be ch rged in the sunlight no m tter whether the switch h s been turned to “On” or
“Off”! And the system will utom tic lly cut off the ch rging current while the b ttery is ch rged to its high
volt ge limit (fully ch rged).
* Adjusting the potentiometer of b ttery b ckup to re ch higher output volt ge will get better perform nce,
however it will shorten the tot l pump oper ting time s the l rger the working volt ge of the pump is, the more
power the pump will consume.
3. CAUTIONS
) 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:
) 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., 0 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:
