3. Setup
Proper installation is crucial for the safe and optimal performance of your Deye Hybrid Solar Inverter. It is recommended that installation be performed by a qualified electrician or solar professional.
3.1 Unpacking and Inspection
- Carefully unpack the inverter and all accessories.
- Inspect the unit for any signs of physical damage during transit. Report any damage to your supplier immediately.
- Verify that all components listed in the packing list are present.
Figure 2: Inverter Packaging and Port Details
3.2 Mounting the Inverter
The Deye inverter is designed for wall-mounted installation. Choose a location that is:
- Well-ventilated and free from direct sunlight.
- Protected from rain and moisture (IP65 rated, but sheltered installation is recommended).
- Strong enough to support the inverter's weight (36.8 kg).
- Accessible for maintenance and connections.
3.3 Electrical Connections
All electrical connections must comply with local and national electrical codes.
- PV Input: Connect the solar panel strings to the PV1-1, PV1-2 inputs. Ensure correct polarity and voltage within the specified MPPT range (200V-650V).
- Battery Connection: Connect the battery bank to the BATTERY terminals. Ensure correct polarity and that the battery voltage is within the 40-60V range. The inverter supports Lead-acid or Li-Ion batteries and features self-adaption to BMS for Li-Ion types.
- Grid Connection: Connect the inverter to the utility grid via the GRID terminals.
- Load Connection: Connect your household or commercial loads to the LOAD terminals.
- Generator Connection (Optional): If using a backup generator, connect it to the GEN terminals.
- Communication: Connect communication cables (RS485, CAN) for Battery Management System (BMS) integration and monitoring. A WIFI module is also available for remote monitoring.
