Growatt SPF ES Inverter WiFi Setup for Remote Monitoring

Key Takeaways

• The WiFi / GPRS module is an optional, plug-and-play device for remote monitoring.
• Monitoring software is available for download from the official Growatt website, www.ginverter.com.
• All wiring must be performed by a qualified person.
• If you encounter persistent issues after following basic setup steps, contact a professional technician.

How to Set Up Your Growatt SPF ES Inverter for WiFi Monitoring

Setting up WiFi monitoring for your Growatt SPF ES series inverter allows you to track your solar system's performance from anywhere using a mobile phone or website. This process involves installing an optional WiFi / GPRS module and then configuring the monitoring software. The Growatt SPF 3500 ES and SPF 5000 ES models support this functionality.

The most common reason for issues during setup is an incorrectly installed WiFi / GPRS module or a failure to download and configure the correct monitoring software. Ensure the module is securely connected to the designated port and that you are using the software from the official source.

Diagnosis and Setup Steps

Follow these steps to set up WiFi monitoring for your Growatt SPF ES inverter. Remember that all wiring must be performed by a qualified person.

1. Obtain the WiFi / GPRS Module: The WiFi / GPRS module is a plug-and-play monitoring device, but it is optional and typically purchased separately. Ensure you have the correct module compatible with your Growatt SPF ES inverter.
2. Locate the WiFi/GPRS Communication Port: On your Growatt SPF ES inverter, identify the dedicated WiFi/GPRS communication port. This port is specifically designed for the monitoring module.
3. Install the WiFi Module: Before proceeding, ensure the inverter is completely powered down and isolated from all power sources (AC, DC, and battery), and allow sufficient time for internal capacitors to discharge. Improper handling may void your warranty. Carefully plug the WiFi / GPRS module into the WiFi/GPRS communication port on your inverter. Ensure it is seated firmly and correctly.
4. Download Monitoring Software: The monitoring software is downloadable from the official Growatt website, www.ginverter.com. Visit this website using a computer or mobile device to download the appropriate application or software for your system.
5. Install and Configure Software: Install the downloaded software on your mobile phone or computer. Follow the instructions provided with the WiFi / GPRS module or within the software itself to configure the connection to your inverter. This typically involves connecting to the module's temporary WiFi network, entering your home WiFi credentials, and then registering your inverter.
6. Verify Connection: Once configured, the software should display data from your PV system. Check the application or website interface to confirm that the inverter is communicating and reporting data correctly. You should be able to monitor the status of your PV system from your mobile phone or from the website anytime anywhere.

Common Setup Issues and Solutions

Monitoring and Communication Features

The Growatt SPF ES series inverters, including the SPF 3500 ES and SPF 5000 ES, are designed with various communication ports to facilitate monitoring and system expansion.

• WiFi/GPRS Communication Port: This is where the optional WiFi / GPRS module connects, enabling remote monitoring of your PV system's status.
• USB Communication Port: This port is available for local data access or specific configurations.
• BMS Communication Port: This port supports CAN/RS485 protocols for communication with compatible lithium batteries that have a Battery Management System (BMS). When using a lithium battery with BMS communication, you can select "LI" in Program 05: Battery type. For lithium batteries without BMS communication, "User-Defined 2" can be selected, which, like "User-Defined", allows you to set battery charge voltage and low DC cut-off voltage in programs 19, 20, and 21.
• RS485 Communication Port (for expansion): An additional RS485 port is available for other expansion purposes, such as connecting to external devices or for parallel communication. For parallel systems, ensure parallel communication cables are connected well to avoid "CAN fault" (Code 80).

The ability to monitor your system remotely is a key benefit of the Growatt SPF ES inverters. It allows you to track energy production, consumption, and battery status, helping you optimize your solar power usage.

Safety

Working with solar inverters and battery systems involves electrical hazards. Always prioritize safety.

• Qualified Personnel: All wiring must be performed by a qualified person. Do not attempt electrical work if you are not certified or experienced.
• Disconnection: To reduce the risk of electric shock, disconnect all wirings before attempting any maintenance or cleaning. Turning off the unit alone will not eliminate this risk.
• No Disassembly: Do not disassemble the unit. If service or repair is required, take it to a qualified service center. Incorrect re-assembly can lead to electric shock or fire.
• Grounding: The inverter must be connected to a permanent grounded wiring system. Ensure compliance with local requirements and regulations for installation.
• Breakers: Install a separate AC breaker between the inverter and the AC input power source. For the SPF 3500 ES, a 40A AC breaker is recommended, and for the SPF 5000 ES, a 50A AC breaker is recommended. Also, install a separate DC circuit breaker between the inverter and PV modules.

When to call a technician instead

While installing the WiFi / GPRS module is designed to be plug-and-play, the overall inverter system involves complex electrical connections. You should call a qualified technician if:

• You are unsure about any wiring or electrical connections. All wiring must be performed by a qualified person.
• The inverter displays fault codes that you cannot resolve using the manual's troubleshooting steps, especially internal component failures (e.g., Fault code 09/53/57).
• The system fails to power on or operate correctly after installing the WiFi / GPRS module and you have verified basic connections.
• You encounter persistent communication errors with the WiFi / GPRS module or monitoring software despite following all setup instructions, including issues like "Li battery can't communicate to the inverter" (Code 20), "CAN fault" (Code 80), "Internal communication error" (Code 62), "Host loss" (Code 81), "BMS communication loss" (Code 33), "The input status is different in parallel system" (Code 15), "Input phase is not correct" (Code 16), "The output phase not correct in parallel" (Code 17), or "Negative power fault" (Code 60).
• You need to open the inverter's enclosure for any reason. Do not disassemble the unit yourself; take it to a qualified service center.

Attempting repairs or modifications without proper qualifications can void your warranty and pose significant safety risks.
