4. Opsætning og installation
Proper installation is crucial for the performance and safety of your inverter. Follow these steps carefully:
- Montering: Choose a dry, well-ventilated location for mounting the inverter. Ensure sufficient clearance around the unit for airflow, especially around the fan.
- Batteriforbindelse: Connect the 24V battery bank to the DC input terminals of the inverter. Ensure correct polarity (+ to + and - to -). Use appropriate gauge cables for the power rating.
- Solar Panel Connection (Optional): If using solar panels, connect them directly to the designated solar input terminals on the inverter. The integrated MPPT charge controller will manage the charging process.
- AC Input Connection (Optional, for UPS/Charger Function): Connect the AC grid power (e.g., shore power, generator) to the AC input terminals if you intend to use the integrated charger or UPS function.
- AC-udgangstilslutning: Connect your 230V AC appliances or distribution panel to the AC output terminals.
- Fjernbetjening (valgfrit): If you have the optional ECTIVE RC3 remote control, connect it to the remote port for convenient monitoring and control.
- Jording: Sørg for, at inverteren er korrekt jordforbundet i henhold til lokale elektriske forskrifter.
Note: For detailed wiring diagrams, refer to the included installation guide.
5. Betjeningsvejledning
Once installed, operating the ECTIVE SSI 15-1500W inverter is straightforward:
- Tænd: Locate the main power switch on the inverter and switch it to the "ON" position. The inverter will perform a self-test.
- Overvågning: Observe the indicator lights or the optional remote display (RC3) for operational status, battery voltage, output power, and charging status.
- Tilslutning af apparater: Plug your 230V AC appliances into the inverter's AC output. The pure sine wave output ensures compatibility with sensitive electronics like microwaves, air conditioners, and welding equipment.
- Solopladning: If solar panels are connected, the MPPT controller will automatically begin charging the batteries when sufficient sunlight is available. Solar power is prioritized for consumption, with excess power used for battery charging.
- Grid Charging / UPS Mode: If AC input is connected, the inverter can charge the batteries from the grid. In UPS mode, it will seamlessly switch to battery power if the grid power fails, and back to grid power when it returns.
- Overbelastningsbeskyttelse: In case of an overload, the inverter will automatically shut down to protect itself and connected appliances. Reduce the load and restart the inverter.
- Sluk: To shut down the inverter, switch the main power switch to the "OFF" position.
6. Vedligeholdelse
Regelmæssig vedligeholdelse sikrer din inverters levetid og optimale ydeevne:
- Rensning: Periodically clean the exterior of the inverter with a dry, soft cloth. Ensure ventilation openings and fans are free from dust and debris. Do not use liquid cleaners.
- Forbindelser: Regularly check all electrical connections (battery, solar, AC input/output) for tightness and corrosion. Loose connections can cause overheating and poor performance.
- Batteriets sundhed: Monitor your battery bank's health. Ensure batteries are properly charged and maintained according to their manufacturer's guidelines.
- Ventilation: Sørg for, at installationsområdet er godt ventileret og fri for forhindringer.
