Smart Meter Mode - Charging during the night
My energy plan is set to "Smart Meter Mode."
During the night (and during the day, though it's less noticeable then), the Zendure SolarFlow 2400 pro constantly switches between "Charging" and "Discharging at full power."
My setup:
- Zendure SolarFlow 2400 Pro
- Zendure P1 Meter
- Landis+Gyr E350 (Smart Meter) in the Netherlands
The Zendure app displays the following message:
Dutch: "Smart CT heeft zojuist gedetecteerd dat een onbekend energiesysteem stroom van uw woning teruglevert aan het openbare net. Wanneer het feedbackvermogen 50W overschrijdt, start HEMS met AC-laden en wordt er een buffer van 50W aangehouden tijdens het laden."
"Smart CT has just detected that an unknown energy system is feeding power from your home back to the public grid. When the feedback power exceeds 50W, HEMS starts AC charging and a buffer of 50W is maintained during charging."
My questions:
- What is going wrong here?
- Is the P1 meter functioning correctly?
- It appears there is a lag/delay between the P1 meter and the SolarFlow, causing the system to overcompensate constantly. See screenschot of the Load and Unload during the Night
