Dear customer,
The issue you described regarding the slow response of the SolarFlow 2400 AC with firmware V1.0.19 to changes in solar input, particularly during cloudy weather, aligns with known concerns about response delays in the system. Here are some insights and suggestions based on the knowledge base:
Observations and Known Behavior:
Response Delay in Adjusting Power:
The system is designed to prioritize stability and avoid frequent fluctuations in power adjustments. This may result in slower reductions in charging power when solar input decreases, as observed in your case.
The gradual decrease in charging power (e.g., from 2400W to 0W taking over 30 seconds) is likely a deliberate design to prevent abrupt changes that could impact system performance.
Firmware Behavior:
Users have reported that earlier firmware versions had faster response times. The current behavior in V1.0.19 may be due to changes in the firmware logic aimed at optimizing other aspects of system performance.
Charging from the Grid:
The system may switch to grid charging if solar input drops below a certain threshold, especially if the battery's charge/discharge thresholds are not optimized.
Suggestions for Improvement:
Optimize Energy Scheduling Settings:
In the Zendure app, review and adjust the energy scheduling settings. Ensure that "PV Only Charging" or "Prioritize Solar" is enabled to minimize grid charging.
Battery Charge/Discharge Thresholds:
Consider optimizing the charge/discharge thresholds. For example, set the battery to discharge to 70% before recharging at 80%, rather than starting to recharge at 79%. This can help reduce unnecessary grid charging.
Firmware Update:
If possible, check for any new firmware updates that may address this issue. Firmware updates can often include optimizations for system behavior.
Restart the System:
Restarting the system can sometimes resolve temporary anomalies in power direction identification or response delays.
Provide Feedback to Zendure:
Your detailed observations and experiment results are valuable. Sharing this information with Zendure's R&D team can help them analyze the issue and potentially release a firmware update to address it.
If the issue persists despite these steps, it may require further analysis by Zendure's R&D team. In such cases, providing a video of the behavior, along with the date and time, can assist in identifying the root cause. Let me know if you need further assistance!
Ben niet blij met dit antwoord, ze zeggen dus vanwege stabiliteit......
