4. Configuration et installation
4.1 Environnement d'installation
- Install the inverter indoors, protected from direct sunlight, rain, and moisture.
- Ensure adequate airflow around the inverter for proper cooling. Maintain at least 15 cm (6 inches) of clear space around the unit.
- Avoid installing the inverter in areas with corrosive gases, excessive dust, or high humidity.
- Mount the inverter horizontally on a stable, non-flammable surface.
4.2 Connexions de câblage
Follow these steps for connecting the inverter to your battery bank and AC loads. Always ensure the inverter is switched OFF before making any connections.

4.2.1 Connexion de la batterie
- Connect the positive (+) terminal of the 12V battery bank to the red DC input terminal of the inverter.
- Connect the negative (-) terminal of the 12V battery bank to the black DC input terminal of the inverter.
- Ensure the battery cables are of appropriate gauge and length to minimize voltage goutte.
- Serrez bien toutes les connexions.
4.2.2 AC Load Connection
- Plug your AC appliances directly into the AC output sockets on the front panel of the inverter.
- Ensure the total power consumption of all connected AC loads does not exceed the inverter's continuous power rating (3000W).
- The inverter supports various AC outlet types, as shown in Figure 6.

4.2.3 Remote Control and Monitoring (Optional)
- Connect an external remote ON/OFF switch to the RJ11 port for convenient control.
- Utilize the RS485 communication port for remote monitoring with compatible EPEVER devices, such as the MT75 remote meter (see Figure 5).
5. Mode d'emploi
5.1 Mise en marche/arrêt de l'onduleur
- Pour allumer: After all connections are secure, switch the ON/OFF button on the inverter's front panel to the "ON" position. The "POWER" indicator should illuminate.
- Éteindre: Switch the ON/OFF button to the "OFF" position. The "POWER" indicator should turn off.
When using the remote ON/OFF switch, ensure the main switch on the inverter is in the "ON" position for the remote switch to function.
5.2 indicateurs d'état
- Indicateur d'ALIMENTATION : S'allume lorsque l'onduleur fonctionne normalement.
- Indicateur de défaut : Illuminates or flashes to indicate a fault condition (e.g., overload, over-temperature, low voltage). Refer to the Troubleshooting section for details.
6. Entretien
Regular maintenance ensures the longevity and optimal performance of your EPEVER IPT 3000-12 inverter.
