This is not really a zappi problem, but (at least) one customer has reported that they cannot charge their BMW iX3 from their surplus PV generation. Zappi reports "Charge Delayed"
Everything works fine when the PV inverter is turned off.
Eventually the installer changed a "Low Noise" setting on the PV inverter
Here is what they reported on the myenergi Forum (myenergi.info)
PV supplier changed a “low noise” setting from 15khz to 20khz and problem went away.
Looks like the BMW didn’t like the noise that was being generated on the house mains especially when taking power from pv’s or batteries. Prior to the change I tested charging with another iX3 and it failed exactly the same as mine, so BMW’s must be sensitive to noise on the mains.
Mine is a Sunsynk hybrid inverter.
