DANGER!
Risk of death by electrocution.. Grounding causes the system to leave the safety extra-low
voltage range. Protection against directly touching live components must be restored via appropriate isolation measures.
745.487
93
GB
ATTENTION!
– The system voltage of thin-film modules must be positive to avoid corrosion. This require-
not
ment is satisfied in stand-alone systems that are
grounded.
– Danger of damaging the devices (e.g. computer) connected to the Master/Slave bus or the
UART interface.
All
bus connections must be galvanically isolated when the system is
grounded.
The controller does not need to be grounded in stand-alone systems. We recommend not
grounding the controller. Also observe the local regulations.
If required, the controller can be grounded via the positive battery terminal
‘1+’
of the controller.
Observe the following:
n The connection point must lie between the external battery fuse and the controller.
n The connection point can be used as a common ground for all system components.
n Take the grounding of the entire system into account.

If the battery voltage drops below 10.5 VDC, safe operation of the controller can no longer be
guaranteed. The controller stops all functions, especially charging of the battery.
12.1.2 Overheating of the controller
The cooling fins on the rear side and the internal temperature controller prevent the controller from
overheating. If the controller becomes too hot then the battery is no longer charged and the load
output is also switched off if necessary.
12.1.3 Deep discharging of the battery
To protect the battery from deep discharge the controller switches off the load output and the

12.2 Control mode
The controller has 2 control modes:
n Based on the actual state of charge of the battery (SOC control)
n Based on the battery voltage (voltage control)
745.487
109
GB
SOC control is highly recommended because this should result in a longer service life of the battery.
When
SOC control
Voltage control
n If components are directly connected to the battery the controller can only determine the SOC
when the battery currents are measured using a device-specific Steca current sensor. If the battery current cannot be measured then the controller must be switched to
n The controller takes the battery temperature into account for accurate determination of the
charge completion voltage. To do this, the controller measures the room temperature using its
own internal temperature sensor and assumes that the battery is also at room temperature. If
the battery is located in a different room then the external temperature sensor Steca PA TS-S
(optional) should be used.
n The voltage drop in the battery cables distorts the battery voltage measurements and thus also
the actual charging voltage present at the battery. The cable compensation of the controller
compensates for this voltage drop after the first full charge. Additional sensors are not required.
Cable compensation is switched on in the factory settings.

14.3 Functionality
With all brightness-based control functions, the required brightness information is obtained
from the solar module.
14.3.1 Deep discharge protection
The deep discharge protection switches the output on and off independently of the control functions.
Switching behaviour
The deep discharge protection switches the output off when the switch-off threshold is reached and
switches it on again when the battery charge state is the switch-on difference greater than the
switch-off threshold (similar functionality to

14.3.2 Morning light function
The morning light function switches the output on and off based on the brightness and time. The
reference point is the time of dawn. The morning light function is suitable for loads that are operated a certain time before dawn, e.g. heating, feeding system, bus-stop lighting.
Switching behaviour
n The output remains switched on during the switch-on duration ⑤ (Fig. below) and is switched
off by the switch-off duration ⑥ before dawn.
n When dawn is detected the output is switched off, even if the switch-on duration has not
expired.
The morning light function relates to the time of dawn, but the resulting switching time lies
before dawn, i.e. in the past. For this reason, the controller must have performed at least one
night-day changeover before the morning light function can be executed. After this, the controller continuously adjusts the time of dawn to suit any changes (weather, annual changes to
the length of the day, disconnection/covering of the solar module).

The evening light function switches the output on and off based on the brightness and time. The
reference point is the time of dusk. The evening light function is suitable for loads that are operated
a certain time after nightfall, e.g. lighting, heating.
Switching behaviour
n The output remains switched on during the switch-on duration ⑥ (Fig. below) but the switch-
on is delayed by the switch-on delay ⑤.

16 Maintenance
16.1 Controller
The controller is basically maintenance-free. Despite this, it is a good idea to regularly check that the
cooling fins on the front and rear sides of the device are free of dust. Clean the device when necessary as described below.
ATTENTION!
Danger of damage to components.
– Do not allow cleaning agents or objects to enter the inside of the controller from the front
(gaps around the operating elements).
Do not use especially the following cleaning agents:
–
– Solvent-based cleaning agents
– Disinfection agents
– Coarse or sharp-edged cleaning agents
16.1.1 Removing dust
Dust should be removed using compressed air (max. 2 bar).

16.1.3 Checking the charging functionality
Battery
1. If the
symbol flashes, despite a long period of sunshine and correctly connected solar
module then measure the battery voltage.
2. If the battery voltage is very low then charge the battery with an external charger or replace
the battery.
3. Contact your dealer if the batter voltage is greater than 17/34 VDC (Tarom 4545) or
17/34/68 VDC (Tarom 4545–48).
16.2 System
We recommend checking all system components at least once a year, according to the manufacturer's specifications. The following maintenance work is generally recommended:
n Check the cable strain relief.
n Check that all cable connections are secure.
n Tighten screws if necessary.
n Check all contacts for signs of corrosion.
n Check the acid levels in the battery according to the manufacturer's specifications.

Guarantee conditions for PV products

Guarantee conditions for PV products from Steca Elektronik GmbH
In accordance with statutory regulations within the European Union, there is a 2-year legal guarantee
on all Steca PV products for the customer.
All Steca PV products purchased come with a 2-year commercial guarantee from Steca Elektronik
GmbH. For various Steca stand-alone inverters and PV controllers, there is an extended commercial
guarantee of 5 years.
1. Commercial guarantee entitled products
The commercial guarantee applies to Steca PV products manufactured by Steca Elektronik GmbH
(subsequently referred to as Steca) so long as these were evidently bought as new from Steca or from a
Steca authorized wholesaler, specialist retailer or specialist installation company (“products with
commercial guarantee”).
The 5-year commercial guarantee applies to the subsequent Steca product ranges Solsum
1)
, Solarix,
Tarom, Power Tarom and Xtender:
for these products with a manufacture date from 1 June 2012, a 5-year commercial guarantee applies.
This voluntary commercial guarantee begins from the invoice or receipt date and ends 5 years after the
receipt date (receipt of purchase held by the customer), or at the longest, 5.5 years after the
production date. This commercial guarantee applies to products which have been purchased within an
EU country, and in other countries in which Steca sells its products on the market.
The legal guarantee entitlements are not restricted by the commercial guarantee.
To be able to make a claim under the guarantee the customer must provide proof of purchase
(payment receipt).
If a problem arises, the customer must first contact his or her dealer/installer or Steca Elektronik GmbH.
2. Beneficiary of this commercial guarantee
Steca only issues this commercial guarantee to operators who have purchased a product with a
commercial guarantee entitlement and who operate this product themselves (“commercial guarantee
entitled operator”). Evidence is considered to have been provided when the receipt of purchase of the
product is presented to Steca which has been issued to the operator for whom a guarantee has been
authorised. Dealers of any type or trade level acquire no rights and entitlements from Steca whatsoever
from this commercial guarantee.
3. Area of application and duration of the commercial guarantee
The commercial guarantee gives the commercial guarantee entitled operator guarantee claims against
Steca.
This guarantee only covers claims relating to the rectification of product faults.
One shortcoming in terms of the commercial guarantee is a not insubstantial impairment of the
functioning of the commercial guarantee entitled product. Commercial guarantee claims from the
respective vendor and legal product liability entitlements remain unaffected by the commercial
guarantee.
The commercial guarantee applies to failings that evidently occur on the part of the commercial
guarantee entitled operator between the date of purchase (receipt of purchase date) and the end of
the 60th month of a commercial guarantee entitled product (“commercial guarantee period”).
Legal guarantee claims of any kind cannot be drawn from this commercial guarantee. All claims from
the commercial guarantee are to be made by the commercial guarantee entitled operator to Steca
within two months following the first incidence of a fault. Such guarantee claims must be reported to
your point of sale (retail chain) or if necessary, directly to Steca. After two months, no further claims
can be made from this commercial guarantee.

4. Enforcement of the commercial guarantee
The following procedure should be followed in order to process a guarantee claim.
First, it should be clarified to what extent the problem could be caused by the product.
In order to do this, contact your point of sale or report to Steca directly.
A defective device should be sent together with a description of the fault, a copy of the receipt of
purchase and a description of the system used to the point of sale or directly to Steca.
Steca will analyse the device in the case of a guarantee claim and if necessary, repair or replace it and
send it back free of charge.
If there is no guarantee claim entitlement, the customer will be informed and will on request receive at
their own expense a price recommendation for the repair work or an offer for a replacement device.
In cases of inspection of an intact device without faults and rejection of a price recommendation, Steca
retains the right to charge a standard fee.
If no repair or replacement is made, the customer bears the costs for any return postage of the
defective product. However, Steca also offers correct disposal, free of charge, of the defective device.
5. Defects in materials and workmanship
The commercial guarantee and legal guarantee only apply to defects in materials, workmanship and
software, insofar as these can be attributed to inadequate professional ability on the part of Steca.
Steca reserves the right at its own discretion to repair, adapt or replace the faulty products. If an error
is found in the software, a software update can be installed. There is no general claim entitlement for a
software update for a product extension.
For products repaired or replaced by Steca, the commercial guarantee applies up to the expiration of
the original period of guarantee.
As a rule, Steca offers a 6-month guarantee on repair work.
6. Rights from the commercial guarantee – damages and costs not covered
In the event of a fault to commercial guarantee entitled products occurring during the commercial
guarantee period, a free repair or exchange of a product exhibiting at least the same specifications is
carried out at the discretion of Steca. The repair and the exchange are carried out exclusively in the
Steca factory or at service points authorised by Steca.
The original or at least equivalent packaging must be used for shipment to Steca. The full cost of
shipment is to be met by the commercial guarantee entitled operator. If the fault is covered by the
guarantee, Steca bears the costs for the return postage. If the fault is not covered by the guarantee,
the customer will be charged for the return postage. Any damage caused during transport must be
reported immediately to the carrier company.
Any claims from this commercial guarantee, above and beyond a free repair or a free replacement are
excluded, in particular, claims for reimbursement for financial losses caused by failings, such as lost
income resulting from failure in output, assembly and disassembly costs and the costs of fault
diagnostics. Steca can claim a lump sum from the commercial guarantee entitled operator for work per
product supplied, if no significant fault is detected on the commercial guarantee entitled product
supplied, or if no claim is made on the commercial guarantee on other grounds.
This commercial guarantee does not cover service work conducted on the product on site, or repairs or
replacement.

7. Guarantee exclusion clause
The guarantees on products from Steca Elektronik GmbH described under point 1 are not valid in the
event that the fault is attributable to: (1) specifications, designs, accessories, or components added to
the product by the customer or at the wish of the customer, or special instructions from the customer
relating to the production of the product, the connection (of Steca products) with other products, or
copies of the product, that are not explicitly approved by Steca Elektronik GmbH; (2) modifications or
adjustments to the product by the customer, or other causes due to the customer; (3) incorrect
arrangement or installation, incorrect or careless handling, accident, transport, overvoltage, storage or
damage caused by the customer or other third party; (4) unavoidable accident, fire, explosion,
construction or new construction of any kind in the environment where the product is located, due to
natural phenomena such as lightning, earthquakes, flooding, or storms, or any other cause outside the
control of Steca Elektronik GmbH; (5) any other cause that could not be foreseen or avoided with the
technology used in manufacturing the product; (6) if the serial number and/or the type number has
been manipulated or rendered unreadable; (7) the use of the solar products in a movable object, for
example ships, mobile homes, or others; (8) lack of observance of the care instructions and
maintenance measures relating to the product recommended by Steca in the operating instructions.
(9) The housing is damaged, contaminated or painted in such a manner that no cleaning or repair is
possible.
8. Transferability of the commercial guarantee
The commercial guarantee described applies only to those entitled to the commercial guarantee (see
item 2).
The guarantee described here is not transferable to a third party. The customer shall not transfer his
rights or responsibilities resulting from this in any way, without the prior written approval of Steca
Elektronik GmbH. Furthermore, Steca Elektronik GmbH shall in no case be liable for indirect damage or
loss of profit. Unless otherwise specified by any applicable compulsory legislative regulations, Steca
Elektronik GmbH shall also not be liable for any other damages other than those for which Steca
Elektronik GmbH has hereby explicitly accepted liability.
9. General rules
Claims of the commercial guarantee entitled operator from this commercial guarantee are only
transferable to a third party with the previous written approval of Steca.
The effectivity of the remaining rules of the commercial guarantee remains unaffected should one of
the stipulations in this commercial guarantee be or become ineffective. In place of the ineffective
stipulation or stipulation that becomes ineffective, an effective rule is automatically agreed, that comes
as closely as possible to the ineffective stipulation/stipulation that becomes ineffective in terms of its
economic content. In the case of a missing stipulation, the preceding rule applies accordingly. This
commercial guarantee is exclusively subordinate to the legislation of the Federal Republic of Germany
excluding the regulations of international private law and UN CISG (Convention on Contracts for the
International Sale of Goods). The exclusive place of jurisdiction for all contentions resulting from or in
connection with this commercial guarantee is Memmingen, Germany; provided the customer is a
registered trader.
