Installation og opsætning
1. Montering af inverteren
Choose a dry, cool, and well-ventilated location for mounting the inverter. Ensure there is sufficient space around the unit for airflow, especially around the cooling fans. Mount the inverter securely using appropriate fasteners.
2. Batteritilslutning
- Ensure the inverter is turned off and all loads are disconnected.
- Tilslut det positive (+) batterikabel (rødt) til den positive (+) pol på inverteren.
- Tilslut det negative (-) batterikabel (sort) til den negative (-) terminal på inverteren.
- Sørg for, at alle forbindelser er tætte og sikre for at forhindre volttage drop og overophedning.
- It is recommended to install an appropriate fuse or circuit breaker close to the battery for protection.
3. Solar Panel Connection (Optional)
If using solar panels, connect them to the dedicated solar input terminals. Ensure the solar panel voltage and current are within the inverter's specifications (max 550W, 70V). Observe correct polarity.
4. AC Input (Shore Power) Connection (Optional)
Connect a standard AC power cord from your shore power source to the AC input terminal on the inverter. This enables the integrated battery charger and NVS/UPS functions.
5. AC-udgangstilslutning
Plug your AC appliances into the AC output socket(s) on the inverter. Ensure the total power consumption of your appliances does not exceed the inverter's 2500W continuous output.

Operation
Tænd/sluk
After all connections are securely made, press the power button on the inverter to turn it on. The indicator lights will illuminate, showing the operational status. To turn off, press the power button again.
Overvågning
The inverter may feature an LCD display or LED indicators to show battery voltage, output power, charging status, and error codes. Refer to the specific display details for your model.
Using the MPPT Charge Controller
When solar panels are connected and sufficient sunlight is available, the integrated MPPT controller will automatically begin charging the connected battery bank. It optimizes the power extraction from the solar panels to maximize charging efficiency.
Using the Battery Charger and NVS/UPS
When shore power is connected, the integrated battery charger will automatically charge the battery bank. The Network Priority Switching (NVS) function ensures that connected AC loads are primarily powered by shore power. If shore power is disconnected or fails, the UPS function will seamlessly switch the load to be powered by the inverter from the battery bank, providing an uninterrupted power supply.

This image illustrates the versatile applications of the ECTIVE SSI 25, suitable for mobile air conditioners, hair dryers, electric grills, dishwashers, and small ovens, highlighting its utility in motorhomes, camping, boats, or as an emergency power supply for household appliances.
Opretholdelse
Regular maintenance ensures the longevity and reliable operation of your ECTIVE SSI 25 inverter.
- Rensning: Rengør jævnligt inverterens yderside med en tør, blød klud. Brug ikke flydende rengøringsmidler eller opløsningsmidler.
- Ventilation: Ensure the cooling vents are free from dust and debris. Use compressed air to clear any blockages if necessary.
- Forbindelser: Regularly check all electrical connections (battery, solar, AC input/output) for tightness and corrosion. Tighten any loose connections.
- Batteriets sundhed: Monitor the health of your battery bank. A healthy battery is crucial for optimal inverter performance.
