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.
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.
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- m) and have a suitable cable diameter size to minimize loss, e.g. use .5 mm² at 10 A and m length; 4 mm² at 0 A and m length; 6 mm² at 30 A and m length.
2.3. Grounding Grounding the regulator is not technically required when installing a standalone solar system. Observe, however, the corresponding applicable national regulations.One ground is possible for all positive connections; however, only one connection is possible for a negative ground. 96 MADE IN GERMANY X X 187 44 44 96 MADE IN GERMANY Observe that there is no common connection, e.g. across a ground connection, the minus module connections, battery minus and load minus.
4. Operating the system regulator The display shows a variety of system data by symbols and digits. Both buttons control all settings and display windows. Display window for system information and messages 96 MADE IN GERMANY 4.1. Display and Operation Elements Button for switching display windows or calling up the settings 44 Manual load switch, or confirmation button in program mode 4.2.
4.2.3. Module current Displays the actual produced solar module‘s current output. 4.2.4. Charging current Displays the charging current flowing into battery from the solar module. 4.2.5. Load current Displays the current drawn by the load output. 4.2.6. Ah – Battery charging meter Displays the accumulative sum of recharged Ah since the initial installation or reset. Press both buttons for 3 seconds to reset the meter to 0. Ever when the battery is disconnected the value remains. When 99.
Using this SOC information, you always have an accurate overview on the actual battery level. Using the SOC, the regulator also controls the selection of the charging procedure and the deep discharging protection in order to ideally maintain the battery. If one of the parameters cannot be recorded because for example, a consumer or charging source is directly connected to the battery, the SOC calculation is invalid. The regulator can then be set to the more simplified voltage-guided control, see chapter 6.
6.3. Gel / Liquid Battery Type Setting The standard setting is “Li”. The setting of the battery type influences the cutoff voltage of the controller. If you use a Gel or AGM battery, you have to change the battery type to GEL. Caution! An incorrect battery type setting can damage the battery! 6.4. Night Light Function Setting This setting provides three options in the following order: • OFF: The function is deactivated (default). • Operating time-choice of 1 to 8 hours.
E) Start the auto-test with the left button. The test expires quickly and automatically. F) If there is no error, this window is displayed shortly (1. sec.) Afterwards, all LCD segments fade in and out for 1 second. Then the auto-test window reappears in the display. G) If there is an error, an error code is displayed. Note the code – your Steca distributor can help you find the error with this information. After 30 seconds the display returns to the auto-test window. During this the display flashes.
Display Meaning Cause / Remedy Excessive temperature regulator turned off the consumer due to internal over heating. Let regulator cool. Check the cause for overheating (installation site, other heat sources). Possible reduce charge or load current. Ensure the regulator has proper ventilation. No solar module connected. Check module connection. Module connected with reverse polarity, perhaps the module feed wire is disrupted. (Detection lasts approx. 15 minutes) Battery voltage too low. Voltage <10.
Display Meaning Cause / Remedy No battery connected or connection interrupted. Supply only by solar module. Connect battery to regulator and check battery fuse. Storage battery connected with reverse polarity. Disconnect battery and connect to regulator with correct polarity. 8. Legal Guarantee In accordance with German statutory regulations, there is a 2-year legal guarantee on this product for the customer.
