1. Introduction
Dear Costumer, thank you for purchasing the solar pump kit.
With this solar pump kit you purchased a product manufactured according to the cur-
rent state of technology.
This product fulfils all requirements of the valid European and national regula-
tions. The conformity was proved. The relevant declarations and documentati-
on are deposited with the manufacturer.
To maintain this state and guarantee a safe operation, you as the user will have to fol-
low this operating manual!
2. Safety Instructions
- In case of damages caused by not following
this operating manual, the warranty rights
will expire! We exclude liability for any
consequential damages!
- We exclude liability for property or
personal damages caused by inappropriate
handling or not following the safety instructions.
- In these cases any guarantee rights will expire.
Due to safety and admission reasons (CE) it is not allowed to arbitrarily reconstruct
and/or change the solar pump kit.
Therefore, please keep to the operating manual.
The accident prevention rules of the association of the industrial trade cooperative
association for electric plants and working material are to be considered in industrial
environments
3. Intended Use
- The accumulator station may be used in the esotec pump systems Verona,
Toscana, Napoli, Napoli LED, Siena and Siena LED.
- The accumulator station is installed between pump and solar module.
- The pump may be switched-on or –off via a switch.
- Via a controller, the operating voltage of the pump may be adjusted to 12 and 24 V.
- Operation of the pump optionally via timer or permanent operation
- The integrated accumulator is protected against deep discharge, overcharge
and short circuit.
- Two LEDs provide information about the state of charge and charging of the accumulator.
- The system is plug-in ready and set up within minutes.
Note: The accumulator station must not be positioned and set up in the blazing
sun or in the water.
Mode of operation:
The accumulator station is interconnected between the solar module and the pond
pump.
In case of an optimal solar radiation, the solar module will generate more electrical
energy than required by the pond pump. This excess energy is then stored in the
accumulator and will be available for the pond pump in case of shadow or darkness.
If the battery voltage is within the operative range, the pump will be switched-on and
the green LED is lit up. If the accumulator is discharged, the pump is switched-off and
the red LED is lit up. The yellow LED is lit up as soon as the accumulator is charged.
The electronics protect the accumulator against deep discharge, overcharge or short
circuit.
The charging of the accumulator always has priority over the operation of the
pump.
Throughout the summer months with full solar radiation, this results in the fol-
lowing operating characteristic:
In the morning, the discharged accumulator is charged via the solar module (the yel-
low LED is lit up). The accumulator is still discharged from the day before (the red
LED is lit up).
The pump is switched-on and the LED is lit up green as soon as the battery voltage
has reached its activation threshold (approx. 12.65 V). In summer with full solar radia-
tion, the solar module will generate enough energy in order to supply the pond pump
with energy and simultaneously charge the accumulator.
In the evening and in case of decreasing solar radiation, the pump is increasingly sup-
plied with energy by the accumulator. The system will run until the accumulator has
reached its deep discharge threshold (approx. 11.8 V). The pump and the LED
lighting are automatically switched-off and the LED is lit up red.
The accumulator will then be charged the following morning via the solar module (yel-
low LED is lit up).
Depending on the solar radiation, this process may take a cou-
ple of hours.
The output voltage of the accumulator station may be adjusted via the controller on
the front side. In times with little sunshine, the controller should be adjusted to the
lowest setting.
4. Assembly/installation and start of operation
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.
3. Completely unroll the cable at the pump.
4. Insert the plug on the pump cable in the
built-in socket
“OUTPUT DC 12-24 V”
a
the accumulator station. Screw the cap nut
tight.
Please make sure that the switch is in
OFF
position.
5. Completely unroll the cable at the accumulator station.
6. Insert the cable with the socket into the plug of the
solar module. Screw the cap nut tight.
7. Put the pump into the pond. Please pay attention to the operating manual of the
pump. It contains important notes regarding the start of operation and maintenan-
ce.
8. Leave the switch in the
„OFF“
position
and charge the accumulator for 2 to 3
hours during sunshine. When setting the
switch to its
“ON”
position, the green LED
will be illuminated and the pump starts to
work.
9. The operating voltage of the pump may be
adjusted to 12V and 24 V. This is done by
means of a controller. Thus, the power of
the pump is adjustable.
Note:
Full power should only be chosen in
high summer. The increased power con-
sumption leads to a reduction of the maxi-
mum operating time of the accumulator.
Note:
The plugs and sockets are predcted against inverse polarity. Do not apply force
when inserting the plugs. The glass of the solar module is fragile.
Note:
The accumulator station must not be set up in the blazing sun.
5. Operating mode of the accumulator station
5.1 Settings via toggle switch:
1. Position ON :
If the built-in accumulator has
the correspondingly high voltage, the pump
starts to run (green LED is illuminated) and the
accumulator is charged if excess energy is
available. In case the capacity of the solar
module should now be reduced due to clouds,
the pump will be supplied with energy via the
accumulator. In the evening, the pump will still
run for some time until the control deactivates
the accumulator (red LED is illuminated).
2. Position 0 (OFF) :
The pump is switched-off . The accumulator is charged via the
solar module and the electric energy is stored. The yellow LED is lit up as soon as the
accumulator is charged via the solar module.
Note:
In case you would like to achieve a particularly long operating time in the eve-
ning, then set the switch to its
“OFF”
position during the day and to its
“ON”
positi-
on in the evening.
