2. Informació de seguretat
Please observe the following safety precautions during installation, operation, and maintenance of the micro inverter:
- La instal·lació ha de ser realitzada per personal qualificat d'acord amb els codis i les normatives elèctriques locals.
- Do not attempt to repair the inverter yourself. Contact qualified service personnel.
- Ensure the inverter is disconnected from all power sources (DC and AC) before performing any service or maintenance.
- The inverter can become hot during operation. Avoid touching it directly.
- Do not immerse the inverter in water or expose it to excessive moisture.
- Assegureu-vos de posar a terra correctament l'inversor.
- Keep children away from the inverter and solar installation area.
3. Configuració i instal·lació
Follow these steps for proper installation of your Deye Micro Inverter:
3.1 Muntatge de l'inversor
Mount the inverter in a well-ventilated area, preferably under the solar panel or on a suitable mounting structure. Ensure adequate clearance for air circulation around the unit.

3.2 Connexions elèctriques
Refer to the diagram below for a simplified installation overview. Ensure all connections are secure and correctly polarized.

Figura 4: Simplified installation diagram. This diagram illustrates the three main steps: 1. Direct connection of solar modules to the micro inverter inputs. 2. Connecting the AC output to the solar cable. 3. Plugging the solar cable into a standard wall outlet.
- Connexió d'entrada de CC: Connect the DC cables from your solar panels to the PV1+ / PV1- and PV2+ / PV2- inputs on the inverter. Ensure correct polarity. The inverter supports two independent MPPT inputs.
- Connexió de sortida de CA: Connect the provided 5-meter Schuko cable to the AC output port of the inverter.
- Connexió a la xarxa: Plug the Schuko cable into a suitable and properly grounded wall outlet.

3.3 WiFi Setup
The inverter includes integrated WiFi for monitoring performance. Refer to the separate Deye monitoring app instructions for setting up the WiFi connection and accessing real-time data.
4. Instruccions de funcionament
Once installed and connected, the Deye Micro Inverter will automatically begin operation when sufficient sunlight is available to the solar panels. The inverter converts the DC power from the panels into AC power, which is then fed into your home's electrical grid.
Seguiment del punt de potència màxima (MPPT)
The inverter utilizes MPPT technology to continuously optimize the power output from your solar panels, ensuring maximum energy harvest even under varying conditions like partial shading or changing temperatures.

5. Manteniment
The Deye Micro Inverter is designed for minimal maintenance. However, regular checks can help ensure optimal performance and longevity:
- Inspecció visual: Periodically inspect the inverter and all cables for any signs of damage, corrosion, or loose connections.
- Neteja: Keep the inverter's cooling fins free from dust, dirt, and debris to ensure proper heat dissipation. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents.
- Seguiment del rendiment: Regularly check the inverter's performance via the WiFi monitoring system to identify any anomalies.
- Condicions ambientals: Ensure the inverter is not exposed to extreme temperatures or direct sunlight for prolonged periods if not designed for such exposure. The IP67 rating provides protection against dust and temporary immersion in water.
6. Solució De Problemes
If you encounter issues with your Deye Micro Inverter, consider the following troubleshooting steps:
| Problema | Causa possible | Solució |
|---|---|---|
| Sense potència de sortida | No sunlight; DC input not connected; AC output not connected; Grid outage | Check sunlight conditions; Verify DC connections; Verify AC connection to grid; Check grid status |
| Sortida de baixa potència | Partial shading on panels; Dirty panels; Faulty panel; Inverter overheating | Clear shading; Clean panels; Inspect panels for damage; Ensure proper ventilation around inverter |
| Problemes de connexió Wi-Fi | Incorrect network settings; Router too far; Signal interference | Reconfigure WiFi settings; Move router closer or use extender; Reduce interference sources |
| Inverter indicator light off | No power (DC or AC); Internal fault | Check all power connections; If problem persists, contact support |
