Deye DL100B-WIFI data logger
Product information
The Deye DL1000B-WIFI is the compact Wi-Fi data logger for all owners of an Deye inverter who wish to monitor their photovoltaic system conveniently from a distance. With data updated every minute and seamless integration with the Deye cloud, you can keep an eye on your solar generation, battery status and grid consumption at all times – directly via the app or web portal.
Key benefits for your system
Comprehensive monitoring
The Deye data logger records inverter data at 1-minute intervals and automatically fills in any missing data points following connection interruptions.
Flexible connectivity
2.4 GHz Wi-Fi enables a continuous cloud connection, whilst Bluetooth BLE 5.3 ensures quick initial setup without the need for a Wi-Fi password.
Remote OTA updates
Firmware updates for loggers and inverters are carried out via the cloud. A visit from a technician is not required.
Robust construction
The IP65 protection rating and an operating temperature range of -40 °C to +65 °C ensure reliable operation under a wide variety of conditions.
Convenient remote monitoring of your photovoltaic system
With the Deye DL1000B-WIFI data logger, your photovoltaic system becomes a smart energy hub. Via the Deye Cloud app for iOS and Android or the web portal, you can view the current status of your inverter at any time, check solar generation and receive system alerts directly on your smartphone. Multiple inverters can also be managed in parallel via a single account – ideal for larger systems or installers.
Should a fault ever occur, remote diagnostics enable the Deye service team to quickly read out error codes and, if necessary, directly adjust the inverter parameters. Thanks to MODBUS command transmission and plug-and-play commissioning, the logger integrates seamlessly into your existing system. This saves you time, avoids unnecessary on-site visits and ensures reliable self-consumption of your solar power.
