5. Operating Instructions
5.1 Equipment Monitoring (Proximal Monitoring)
The SmartESS APP allows you to monitor your inverter's status and data. The device module list displays information such as device status (normal, alarm, fault, standby, offline) and device type (off-grid inverter, grid-connected inverter, integrated energy storage).
Proximal Monitoring (Bluetooth Direct Connection):
Through a direct Bluetooth connection, your mobile phone can connect to the Internet to view device data. Even without a network, you can still view the device data. The APP provides data, control, alarm, and debugging functions, with support for setting passwords to prevent unauthorized access.
- Data: View the energy flow diagram and detailed parameters of the equipment, refreshed in real-time.
- Control: Issue commands to the equipment, set functions, and modify data.
- Alarms: View alarms occurring in the device.
- Debug: Send commands directly to the device; modify data format for sending/receiving.
5.2 Data Logger Management
The APP displays all data loggers under your account. Green icons indicate normal status, while gray icons indicate offline status. You can filter and sort the list by status, name, PN, etc.
- Clicking on a device in the list allows you to enter its detailed information page.
- From the data logger details page, you can modify the alias, debug data, restart the data logger, or delete it.
5.3 Recharge Management
This function allows you to recharge traffic for your data logger and view historical recharge records. Select the data logger(s) to recharge, choose a recharge package, and complete the transaction.
5.4 Charts and Data Analysis
The APP provides various charts and data displays for comprehensive monitoring:
- Charts: View daily (hourly), monthly (daily), yearly (monthly), and total power generation data. Parameters are dynamically obtained from the network.
- Parameter Analysis: Displays device parameters in chart format, allowing you to switch between different parameters (e.g., voltage) to view statistical data.
- Data: Provides a detailed list of all parameter data for the current system. You can switch between different dates to view historical data.
6. Maintenance
6.1 General Care
