Safety Instructions
⚠️ WARNING: Installation of this equipment involves the risk of electric shock. Normally grounded conductors may be ungrounded and energized during a ground fault.
1. Lightning Surge Suppression
Lightning strikes, even nearby, can induce voltage spikes that damage equipment. Felicitysolar inverters feature integrated surge protection. However, extreme surges can exceed this protection. It is recommended to install additional surge protection devices as part of any solar installation, following vendor instructions. Felicitysolar Limited Warranty does not cover "acts of God" like lightning strikes.
2. FCC Compliance
This equipment complies with Class B digital device limits under FCC Rules, providing reasonable protection against harmful interference in residential installations. It generates and radiates radio frequency energy. If not installed and used per instructions, it may cause interference to radio communications. No guarantee against interference in a specific installation is made.
If interference occurs with radio or television reception, try one or more of the following:
- Reorient or relocate the receiving antenna.
- Increase separation between the equipment and receiver.
- Connect the equipment to a different circuit than the receiver.
- Consult a dealer or experienced radio/TV technician.
Unauthorized modifications may void the user's authority to operate the equipment.
Product Overview
The Felicitysolar WiFi Micro inverter (Model: X-RAY-BDM2250W) is designed for solar energy conversion.
Key Components:
- 1. AC Output Cable: Connects the inverter to the AC grid.
- 2. WiFi Dongle (optional): Enables wireless monitoring.
- 3. LED display: Indicates the operational status of the inverter.
- 4. DC input (+): Positive terminal for connecting the PV module.
- 5. DC input (-): Negative terminal for connecting the PV module.
Diagram Description: The product overview includes two images of the microinverter, showing the location of the AC output cable, WiFi dongle port, LED display, and DC input connectors (+ and -).
Installing the Product
Safety
⚠️ WARNING: Installation involves risk of electric shock. Ensure all installation procedures are completed before connecting to the utility grid or energizing AC circuits.
Preparation
- PV modules must be securely attached to the racking.
- Check the microinverter (MI) for intactness and missing components.
- An end cable is prepared. End cables are available in 5m, 10m, and 15m lengths. Contact your distributor for an exchange if the cable is unsuitable.
Mount the Micro inverter
Mount the MI on the racking or PV module frame.
Diagram Description: A series of diagrams illustrates the mounting process, showing how to attach mounting brackets to the microinverter and secure it to solar panel racking rails.
Connections
DC Connection
- Plug the MC4/QC4 terminals into the DC sockets on the MI.
- Ensure each PV module is connected to its corresponding DC socket pair.
Diagram Description: A diagram shows two PV modules connected to a microinverter via DC connectors.
AC Connection
Typical Balcony Solution Topology
For Balcony Solution products, AC output terminals are customized. In this setup, a single inverter is used, and monitoring is achieved via a WiFi connection between the inverter's WiFi dongle and the home router.
Diagram Description: A diagram depicts a balcony solar solution with one microinverter connected to a PV module, leading to an AC outlet. WiFi connectivity for monitoring is indicated.
Typical Trunk Cable Topology
This topology connects multiple microinverters in series via a trunk cable. Monitoring signals are carried by AC current.
Diagram Description: A diagram shows multiple microinverters linked by a trunk cable, with an end cap. It illustrates monitoring signal transmission via AC current and data collection by a datalogger.
Typical Daisy Chain AC BUS Topology
This topology connects multiple microinverters in series using an AC BUS, forming a daisy chain.
Diagram Description: A diagram illustrates microinverters connected sequentially in a daisy chain configuration via an AC BUS.
Monitoring Configuration
Notice: DO NOT CONNECT AC
When the inverter is in DC connected and AC disconnected state, AP mode will be activated. If AC is connected accidentally, unplug AC and DC to allow memory clearance.
Find the AP Number
The AP Number is an eight-digit string found under the barcode on the inverter's sticker.
Diagram Description: A representation of a barcode sticker with an example AP Number format (XXX-XXXXX).
