4.1 Bedradingsdiagram

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).

• Sonpaneelverbinding: 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.
• Batteryverbinding: 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-invoerverbinding: 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.
• WS-uitvoerverbinding: Max Output Power ≤ 3000W. Rate Voltage: 120Vac±5%. Rate Current: 27.5A.

4.2 Batteryversoenbaarheid

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

5.1 Laaimodusse

• PV Priority (Solar Charging): Solar power is prioritized for charging the battery.
• Utility Priority (Electricity Utility Priority): Grid power is prioritized for charging the battery.
• Hibriede laai: A combination of solar and utility power is used for charging.
• Only Solar Charging: Only solar power is used for charging the battery.

5.2 Laai Uitset Werkmodusse

• PV-prioriteit: Solar power is prioritized to supply the loads.
• Nutsvoorkeur: Grid power is prioritized to supply the loads.
• Omskakelaarmodus: 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-skerm en aanwysers
