4. Opsætning og installation
4.1 Udpakning og inspektion
Upon receiving the inverter, carefully unpack it and inspect for any shipping damage. Ensure all components listed in the packing list are present. If any damage or missing parts are found, contact your dealer immediately.
4.2 Montering af inverteren
Mount the inverter vertically on a sturdy wall or surface. Ensure there is sufficient clearance around the unit for proper ventilation (at least 20 cm on all sides). Avoid mounting in direct sunlight, near heat sources, or in areas with excessive dust or moisture.
4.3 Ledningsforbindelser
All wiring must comply with local electrical codes. Use appropriate wire gauges for all connections to prevent overheating and ensure efficient power transfer.
4.3.1 Batteritilslutning
The inverter supports both 12VDC and 24VDC battery systems. The inverter automatically detects the battery voltage. Ensure correct polarity when connecting batteries. For 12V systems, batteries are typically connected in parallel. For 24V systems, batteries are typically connected in series.

Figur 5: The inverter is compatible with various battery types, including Gel, AGM, Flooded (FLD), Lithium (LI), and Sealed Lead-Acid (SLD) batteries.
4.3.2 Tilslutning af solpanel
Connect your solar panels to the designated PV input terminals. Ensure the open circuit voltage (Voc) of your solar array does not exceed the inverter's maximum PV input voltage (500Vdc). Observe correct polarity.
4.3.3 AC Input Connection (Utility/Generator)
Connect the AC utility grid or a compatible generator to the AC input terminals. The inverter supports 220-230VAC input. Ensure proper grounding.
4.3.4 AC-udgangstilslutning (belastninger)
Connect your household or office loads to the AC output terminals. The inverter provides a pure sine wave output suitable for sensitive electronics. Do not exceed the rated output power of the inverter (2300W for 12VDC systems, 4200W for 24VDC systems).

5. Betjeningsvejledning
5.1 Tænd/sluk
After all connections are securely made, switch on the battery breaker first, then the solar array breaker, and finally the AC input breaker (if connected). Press the power button on the inverter to turn it on. To power off, reverse the sequence: turn off AC input, then solar, then battery, and finally the inverter power button.
5.2 LCD-display og kontrolknapper
The inverter features an LCD display that shows real-time operating status, input/output voltages, battery status, and error codes. Use the control buttons (ESC, UP, DOWN, ENTER) to navigate through menus and adjust settings.
5.3 opladningstilstande
Inverteren tilbyder fire valgbare opladningstilstande:
- Solprioritet: Solar power charges the battery first. If solar is insufficient, utility power supplements.
- Prioritet af forsyningsvirksomheder: Utility power charges the battery first. Solar power supplements if utility is unavailable.
- Kun solenergi: Only solar power charges the battery.
- Solenergi og forsyningsvirksomheder: Both solar and utility power charge the battery simultaneously.
5.4 Outputtilstande
The inverter offers three selectable output modes:
- Prioritet af forsyningsvirksomheder: Loads are primarily powered by utility. If utility fails, the inverter switches to battery power.
- Solprioritet: Loads are primarily powered by solar. If solar is insufficient, battery power is used. If both are insufficient, utility power is used (if connected).
- SBU (Solar-Battery-Utility) Mode: Loads are powered by solar first, then battery, and finally utility if both solar and battery are depleted or unavailable.
5.5 Wi-Fi-overvågning (valgfrit)
If equipped with the optional Wi-Fi module, the inverter can be monitored and controlled via a mobile application. Connect the Wi-Fi module to the designated port on the inverter and follow the instructions provided with the module for setup.
