2. Öryggisleiðbeiningar

Please read and follow all safety instructions carefully before installation and operation. Failure to do so may result in electric shock, fire, or serious injury.

• Uppsetning verður að vera framkvæmd af hæfu starfsfólki.
• Gakktu úr skugga um rétta jarðtengingu invertersins.
• Ekki taka inverterinn í sundur. Það eru engir hlutar inni í honum sem notandinn getur gert við.
• Haldið inverternum frá eldfimum efnum, raka og beinu sólarljósi.
• Tryggið næga loftræstingu í kringum inverterinn til að koma í veg fyrir ofhitnun.
• Gakktu úr skugga um að allar tengingar séu öruggar og í lagi áður en rafmagn er sett á.
• Aftengdu alltaf rafmagnið áður en viðhald eða raflögn eru framkvæmd.

4. Uppsetning og uppsetning

4.1 Raflagnamynd

Refer to the following diagram for proper wiring connections. Ensure all connections are secure and follow local electrical codes.

Image: Detailed wiring diagram showing connections for solar panels, battery, AC input (utility/generator), and AC output (loads).

• Tenging sólarplötu: Max PV Input Power 4000W, Max PV Input Current 13A. Total Open Circuit Voltage (Voc) ≤ 450V. Start-up voltage needs to be greater than 150V. Use 12AWG PV wire. At least 4-6 solar panels are typically needed to meet the starting voltage, depending on individual panel specifications.
• Rafhlöðutenging: Compatible with 24V Lithium/Lead-acid batteries. Recommended battery capacity: 200AH. Use 2AWG battery wire. The battery must be connected for the system to operate.
• AC inntakstenging: Connect to 120Vac±5% utility or generator. Frequency: 50Hz/60Hz. Max AC Bypass Current: 40A. Max AC Charge Current: 40A. Use 10 AWG AC wire. Be sure to connect the PE protective conductor (ground) first.
• Tenging við AC úttak: Max Output Power ≤ 3000W. Rate Voltage: 120Vac±5%. Rate Current: 27.5A.

4.2 Samhæfni rafhlöðu

The inverter is compatible with a wide range of 24V battery types.

• Lead-Acid Batteries (Sealed, AGM, Gel, Flooded)
• Lithium rafhlöður

Ensure the correct battery type is selected in the inverter settings for optimal charging and discharge performance.

5. Rekstraraðferðir

The inverter offers flexible operating modes to suit different application requirements.

Image: Diagram showing the four charging modes and three load output working modes of the inverter.

5.1 hleðslustillingar

• PV Priority (Solar Charging): Sólarorka er forgangsraðað til að hlaða rafhlöðuna.
• Utility Priority (Electricity Utility Priority): Grid power is prioritized for charging the battery.
• Hleðsla með blendingsbúnaði: A combination of solar and utility power is used for charging.
• Aðeins sólarhleðsla: Einungis sólarorka er notuð til að hlaða rafhlöðuna.

5.2 Vinnuhamir álagsútgangs

• Forgangur sólarljóss: Solar power is prioritized to supply the loads.
• Forgangsröðun gagnsemi: Grid power is prioritized to supply the loads.
• Inverter hamur: Battery power is used to supply the loads via the inverter.

These modes can be configured via the LCD display to optimize energy usage based on your specific needs.

6. LCD skjár og vísar

The inverter features an LCD display and three LED indicators for real-time monitoring of system data and operational status.
