3. Intended Use
- The accumulator station is universally usable for the energy supply of
pumps and other products.
- The accumulator station has 2 switchable outputs with different voltages.
- Output 1 has an output voltage of 18 VDC. A timer function may be
activated.
- Output 2 has an output voltage of 6 VDC.
- The accumulator station is switched off and on via a switch. The
accumulator is further charged in a switched off state.
- The installed accumulator is protected against total discharge,
overcharging and short circuit.
- LEDs provide information about the state of charge and the charge of
the accumulator as well as about the status of the outputs.
- The system is ready-to-plug-in and set up in a matter of minutes.
Note: The accumulator station must not be set up in the blazing sun or in
the water. It is designed in IP 44 (splashproof).
Mode of operation of the accumulator station:
The accumulator station is interconnected between (a) solar module(s) and
the corresponding devices.
>> For initial start, please rst connect the battery.
See separate instructions! <<
In the sun, the solar module generates electrical energy and charges the
installed accumulator. The connected consumers are switched on as soon
as the accumulator voltage is in an operational range. The LED „SYSTEM“
provides information about the state of charge of the accumulator.
green light means: accumulator is ready for operation!
red light means: accumulator is exhausted and switched off
The electronics protects the accumulator against total discharge,
overcharging or short circuit.
The charging of the accumulator always has priority over the
operation of the consumers.
4. Assembly and Start-up
4.1 Connection of the solar module
A maximum of 50 Wp of solar module capacity
may be connected to the accumulator box.
The solar module is connected at the cable
on the back side of the accumulator box. A 5m
extension cable for this cable is included in the
set.
Depending on the version, you may connect one or several solar modules to
the accumulator station. A single solar module may directly be connected to the
accumulator box with the plug. A Y-distributor is required if you intend to connect
2 solar modules (e.g. 2 pieces 25 Wp). Via the Y-distributor, both solar modules
are joined and then connected to the accumulator station.
If required, the cable may be extended by another 5 m extension cable.
As soon as the solar module is connected and sunlight falls onto the solar
module, the LED „Charging“ will light up . The accumulator is fully charged
if the LED is ashing.
Please note that the solar modules are positioned shadow-free directed towards
the south and that they are mounted in a stable way.
Attention: The electronics in the accumulator box will be destroyed if more than
50 W of solar module capacity is connected!
4.2 Main switch „SYSTEM“
The toggle switch „SYSTEM ON/OFF“ is
applied at the front side of the accumulator
box. The outputs are switched off if this
switch is switched off („OFF“), however, the
accumulator is still charged. In position „ON“,
the LED „SYSTEM“ shines red or green.
When the LED shines green, then the
accumulator is charged sufciently and the outputs may be operated as required
via the buttons on the lid of the box. When the LED shines red, then the outputs
are switched off and the accumulator has to be charged until the LED shines
green (see item 6)
4.3 Connecting the consumers
The accumulator box has 2 outputs. Those
may be switched on or off via the „ON/OFF“
button. The green LED above the button
shines green when the output is active.
All outputs are protected against short
circuit. In case of a short circuit in output 1,
the green LED of the output will additionally ash until the fault is eliminated.
Below, every output is described individually. Output 2 is equipped with a
protective cap. This cap has to be removed before connecting consumers.

Y - Adapter

- Output 1 (output 1):
Output voltage: 18 VDC, max. current load: 1.3 A
The output is switched via the button „ON/OFF“. The timer operation is
activated by pressing the button „Timer“. That means that the output 1
„OUTPUT 1“ is activated for approx. 10 minutes every hour. This mode
of operation is reasonable in particular in case of inadequate insolation.
The output voltage is rmly set to 18 V.
- Output 2 (output 2):
Output voltage: 6 VDC, max. current load: 0.7 A
The output is switched via the button „ON/OFF“. The output voltage is
rmly set to 6 V.
Note: The outputs are connected by means of system plugs.
Corresponding distributors and/or extensions are available as
accessories. The protective caps at the plug-in connections have to
be tightened. Not used outputs have to be closed by means of the
corresponding protective caps. Please do not apply force when plugging
in!
5. Indicator LEDs
LED „SYSTEM“:
green: Accumulator charged and outputs may be
switched on.
red/ green 2x ashing: Accumulator in full charge.
See item: 6.
red: The accumulator is discharged and the outputs
are (OUTPUT) switched off.
LED „CHARGING“: yellow: Accumulator is charged
yellow ashing: Accumulator is fully charged and on
trickle charging.
LED „OUTPUT 1“: green: Output 1 is switched on.
green ashing: Short circuit on output 1.
LED „TIMER“: green: Timer mode is activated.
LED „OUTPUT 2“: green: Output 2 is switched on.
6. Charging process
The LED „System“ will shine red if the accumulator was discharged the
previous evening.
In the morning and when the sun is shining, the charging of the accumulator
will have priority. As soon as the accumulator is charged, the „Charging“ LED
will light up yellow. The charging timer is started when the accumulator reaches
the voltage of 12.7 V and the accumulator will be fully charged for another (30
min. 7 Ah box) 50 minutes (12 Ah box) . The LED „System“ ashes every 10
seconds 2 x from red to green. The outputs (Output) are switched on after
those 50 minutes.
7. Exchanging the accumulator
We recommend exchanging the accumulator approx. every 2 years. A new
identical in construction accumulator is available from the manufacturer or
dealer.
Proceed as follows if you want to exchange the accumulator:
1. Put the main switch (SYSTEM ON/OFF) at the front side of the accumulator
box in the position „OFF“ and unplug all plugs.
2. Turn the accumulator station upside down and loosen the bottom four
screws.
3. Then turn the accumulator box back again and carefully remove the lid.
4. Loosen the + Pole and - Pole connection on the accumulator.
5. Remove the accumulator from the case and insert a new identical in
construction accumulator.
6. Put the cable lugs back onto the poles of the accumulator. In doing so, please
pay attention to the color of the cables: positive pole (red) and negative
pole (black).
7. Close the case in reverse order.
Note: Please only use an identical in construction accumulator with identical
voltage and capacity.
Note: The old accumulator has to be disposed of in an environmentally sound
way. For this purpose, please contact you local authorities, public collection
points or your dealer.
8. What to do during the winter
Fully charge the accumulator in the accumulator box. Use a sunny day for this
purpose and put the switch „SYSTEM ON/OFF“ in the position „OFF“.
Only store the accumulator box (during the winter) in a fully charged state in
a frost-free room. At sunny days, the accumulator box may occasionally be
connected to the solar module for charging purposes. This enables an as long
as possible lifetime of the accumulator.
If you want to operate the accumulator box during the winter, e.g. in connection
with a pond aerator or a string of LED lights (available as accessories), then it is
possible to store the box outdoors. Please pay attention to the fact that the site
is free of snow and that the accumulator box is not under water when thawing
begins. A frost protection for the accumulator box would be advantageous.
9. Troubleshooting
- LED does not shine green despite insolation but the yellow LED shines.
1. The accumulator is not charged sufciently and has not achieved the restart
threshold. The charging process may take several hours when the insolation
is insufcient. (see item 6).
2. Accumulator is exhausted! The accumulator should be exchanged approx.
every 2 years. Please see item 7 of this instruction.
- LED does not shine green despite insolation; when the switch „SYSTEM
ON/OFF“ is switched off and on again, the pump starts to run and the
green LED shines.
1. The accumulator had not achieved its restart threshold. After the switching off
and on of the system, the electronics is reset and the connected consumers
are supplied with energy without waiting for the restart threshold. This is
an absolutely normal process and does not constitute a defect (please see
item 6). However, this method should not be applied because it has negative
effects on the lifetime of the accumulator.
- LED does not shine green despite insolation. The LED System ashes
green two times at an interval of 10 seconds.
1. The accumulator is in the full charge phase. Please pay attention to item 6.
- The green LED above output 1 ashes.
1. There is a short circuit or overcharge on output 1. Please check the
connected device and all plug-in connections (in particular the pumps and
the LED lighting) for tightness.
2. Check the cables for damages or bites by animals.
- The yellow LED „CHARGING“ shines but nothing else works.
1. Is the switch „SYSTEM ON/OFF“ switched on (position ON)?
2. If yes, then switch off the switch „SYSTEM ON/OFF“ for approx. 1 minute
and then on again. This will reset the control electronics.
