1. Safety instructions and liability disclaimer
1.1. The safety instructions are marked as follows
In this manual, safety instructions for personal protection are
marked with this symbol.
The relevant operational safety notes of the system and regulator
are marked in bold.
1.2. General Safety Instructions
Observe the following while installing the regulator and handling
the battery:
Danger of explosion due to improper handling of batteries! Corrosive hazard by leaking battery acid!
Keep children away from batteries and acid! Smoking, fire and
naked lights are prohibited when handling batteries. Prevent
sparking and wear eye protection gear during installation. Observe
and follow the handling instructions in the user manual and on the
battery.
Solar modules generate power from light incidence. Even by low
light incidence solar modules carry the full voltage. Therefore, work
cautiously and avoid sparking during all work. Observe the
responding safety precautions.
During installation and electrical installation, the photovoltaic
system’s DC circuit may carry twice its system voltage value (in the
12 V system up to 24 V, 24 V system up to 48 V).
Use only well-isolated tools!
Do not use any technical measuring equipment that you know is
damaged or defective!
When installing the power line ensure that no fire safety measures
are damaged. The regulator may not be installed and operated in
moist rooms (e.g. restrooms), or rooms, in which easily flammable
gasoline mixtures may be present, such as by gas bottles, paint,
lacquer, solvents etc. Do not store any of the mentioned mixtures in
the room, in which the solar regulator is installed!
If the regulator is operated in a manner not specified by the
manufacturer, the regulator’s constructive protective measures can
deteriorate.
The factory signs and marking may not be modified, removed or
made unrecognizable. All work must be performed in conformity with the national electrical specifications and related local
regulations!
When installing the regulator in foreign countries, information
concerning regulations and protective measures must be obtained
from the relevant institutions / authorities.
Do not begin the installation until you are sure that you have
technically understood the manual and perform the work only in
the order provided in this manual!
The manual must be available during all work performed on the
system, third parties included.
This manual is a component of the system regulator and must be
included with the regulator when given to a third person.

1.3. Scope of Application
This manual describes the function and installation of a regulator for photovoltaic (PV) systems for charging 12 V or 24 V lead batteries for recreational,
residential, business, commercial areas and small businesses.
The charge regulator is only suitable for regulating photovoltaic solar modules. Never connect another charging source to the charge regulator. This
can destroy the regulator and / or source. Consult your specialized dealer or
installer if other charging sources should be used and observe the ”5.1. SOC
Calculation” item in this manual.
The regulator is only suitable for the following chargeable 12 V or 24 V
battery types:
- Lead storage batteries with liquid electrolytes
- Sealed lead storage batteries; AGM, GEL
The respective battery type must be set on the regulator, see ”6.3. Battery
Type Gel / Li”.
Observe the manufacturer’s instructions before connecting the battery.
Important! The regulator is not suited for nickel cadmium,
nickel metal hydride, lithium ions or other rechargeable or
non-rechargeable batteries. Such batteries may not be con
nected to the regulator. Observe the respective battery’s safety
instructions.
The corresponding manufacture’s installation manual must be
observed when installing the remaining components, e.g. solar
module, battery or consumer.
The regulator is not for outdoor use. The regulator must be in
stalled so that it is protected against exposure to the elements,
such as rain and direct sunlight. Vents may not be covered. Do
not expose the battery regulator to rain.
The regulator may only be used for the particular solar applica
tions provided. Also, observe that the permitted, model-speci
fic, nominal currents and voltages are not exceeded.
No liability shall be assumed for any non-compliant usage.
Carefully handle the product.

1.4. Liability Disclaimer
The manufacturer cannot monitor the compliance to this manual as well
as the conditions and methods during the installation, operation, usage
and maintenance of the system regulator. Improper installation can cause
damages and endanger people.
Therefore, we assume no responsibility and liability for losses, damages or
costs that result due to incorrect installation, improper operation, usage and
maintenance or in any manner associated therewith.
Similarly, we assume no responsibility for patent right or other right infringements of third parties caused by usage of this system regulator.
The manufacturer reserves the right, without prior notification, to make
modifications concerning the product, technical data or installation and
operating manual.
Caution:
Opening the regulator, manipulation and repair attempts as well as
improper operation voids the guarantee.

2. Installation
2.1. Installation Site
Only install the regulator near the battery on a suitable surface. This surface
should be solid, stabile, even, dry and nonflammable. The battery cable
should be as short as possible (1-2 m) and have a suitable cable diameter
size to minimize loss, e.g. use 2.5 mm² at 10 A and 2 m length; 4 mm² at
20 A and 2m length; 6 mm² at 30 A and 2 m length.
The regulator and battery should have same temperature ratio for the temperature compensation function of the charging voltage. When the battery
is placed far away from the regulator, an external temperature sensor is
available as an accessory unit.
Do not assemble the charge controller outdoors. The regulator must be
installed so that it is protected against humidity, dripping, splashing and
rain water as well as direct and indirect warming e.g. sunlight.
The regulator also generates heat during normal operation. The installation
or assembly into another housing may not obstruct the rear vents necessary
for cooling the device.
To ensure the air circulation for cooling the regulator, an area of 15 cm on
each side of the regulator must be kept free. The temperature at the installation site may never fall below or exceed the maximal permitted ambient
temperature.
The integrated LC display should be protected against UV rays (e.g. sunlight). Chronic exposure to UV rays can permanently discolor the LCD.
2.2. Connecting the Regulator
Connect the individual components to the symbols provided.
Observe the following connection sequence during commissioning:
1. Connect the battery to the charge regulator - plus and minus
2. Connect the photovoltaic module to the charge regulator
- plus and minus
3. Connect the consumer to the charge regulator - plus and minus
The reverse order applies when deinstalling!
Please observe that the automatic adjustment to 12V / 24V systems
does not function properly, if this sequence order is not followed. An
improper sequence order can damage the battery!
