Frequently Asked Questions - SUN-20K-SG01HP3-AU-AM2 Deye
How do I connect the inverter to my home Wi-Fi?
Use the Deye App or web interface. Ensure the inverter is powered on and in range. Access settings, select Wi-Fi, choose your network, and enter password.
What does error code E01 mean?
E01 indicates a grid voltage fault. Check that the AC input voltage is within the inverter's acceptable range (380-415V). If persistent, consult a technician.
Can I connect this inverter to 48V batteries?
No, this model is designed for high-voltage PV strings, not low-voltage batteries. It does not have a battery input. Use a compatible battery inverter for storage.
How do I update the firmware?
Firmware updates are done via the Deye App or web interface. Download the latest firmware from Deye's support site and follow the update instructions in the manual.
What is the maximum PV string length?
The maximum PV string voltage is 1000V DC. Ensure the open-circuit voltage of your panels at lowest temperature does not exceed this limit. Use appropriate wire gauge.
Is the inverter compatible with single-phase grids?
No, this is a three-phase inverter. It requires a three-phase AC connection. It cannot operate on single-phase systems.
How often should I clean the cooling fans?
Clean the cooling fans and air vents every 6 months or more frequently in dusty environments. Use a soft brush or compressed air to remove dust.
What is the purpose of the LCD display buttons?
The buttons allow you to navigate settings, view real-time data (power, voltage, current), and acknowledge alarms. Refer to the manual for specific menu navigation.
Can I operate the inverter without an internet connection?
Yes, the inverter functions independently without internet. However, remote monitoring and firmware updates require internet connection via Wi-Fi or RS485.
What should I do if the inverter trips repeatedly?
Check for grid instability, overvoltage, or ground faults. Inspect PV connections for shorts. If the issue persists, contact Deye support with error codes.
