3.1 opladningstilstande
The inverter supports four distinct charging modes, allowing you to optimize energy usage based on your preferences and available power sources:
- Kun solenergi: The inverter prioritizes charging batteries exclusively from solar power. The utility grid will not be used for charging.
- Netprioritet: The inverter prioritizes charging batteries from the utility grid. Solar power will be used as a secondary source if the grid is unavailable or insufficient.
- Solprioritet: The inverter prioritizes charging batteries from solar power. The utility grid will only be used if solar power is insufficient or unavailable.
- Net- og solhybrid: The inverter uses both the utility grid and solar power simultaneously to charge the batteries, maximizing charging speed and efficiency.
3.2 AC Output Control
The inverter features an ON/OFF rocker switch to control the AC output. Ensure this switch is in the 'ON' position for the inverter to supply power to your loads.
3.3 Energisparetilstand
To reduce power consumption when no load or a very light load is connected, the inverter can be configured to operate in an energy-saving mode. Refer to the detailed settings in the full manual for activation and configuration.
4. Vedligeholdelse
Regular maintenance ensures the longevity and optimal performance of your WLLKIY ISolar SMX II 3.6KW Hybrid Solar Inverter.
- Rensning: Rengør regelmæssigt inverterens yderside med en tør, blød klud. Sørg for, at ventilationsåbningerne er fri for støv og snavs. Brug ikke flydende rengøringsmidler.
- Ventilator inspektion: The inverter uses an intelligent variable speed fan for cooling. Ensure the fan is not obstructed and operates quietly. Excessive noise or lack of operation may indicate a problem.
- Tilslutningstjek: Annually, inspect all electrical connections (PV, battery, AC input/output) for tightness and signs of corrosion. Loose connections can lead to overheating and system failure.
- Batteriets sundhed: Monitor your battery bank's health according to the battery manufacturer's guidelines. Ensure proper charging parameters are set on the inverter for your specific battery type.
- Miljøforhold: Ensure the inverter's operating environment remains within specified temperature and humidity ranges.
Advarsel: Always turn off all power sources (PV, utility, battery) and wait for the inverter to fully discharge before performing any internal maintenance or inspection.
