Zappi eco+ mode - safe to use?

[Aphelion]

I have a Zappi V2 three phase charger installed, and a M3 LR 21 model... I like the idea of the Eco+ mode that stops charging when surplus is not available, however could this damage the car or cause premature wearing e.g. on the charge port lock which I hear clicking sometimes?

I assume Eco mode is ok to use which only reduces charge rate to 1.4KW rather than stop.

I have switched from Eco+ to Eco as, on cloudy days, the car stopped charging completely after a few Zappi pauses. Haven’t tried for a while, maybe an update has fixed it.

It seems to work fine, honestly, I was even surprised to see the car start charging the next day although I assume it kept the car awake all night but didn't seem to cause any issues - I was very impressed frankly. So Eco+ seems

Increased charge stop/start delay to the max of four minutes, made a huge difference - now cycles much less frequently and should be fine.

Now to test leaving it plugged in overnight to automatically start charging in the morning.

Does charge-standby keep the car awake overnight and possibly kill the 12v battery or something? Seems fine so far, will run an overnight test on Eco+ mode to see what happens.

Have dropped timeout down to two minutes, I hope this is ok. I hear loud mechanical switching noises as it cycles on and off, not sure about the car yet though. I suspect it may actually decrease charge efficiency if the car is left running for long periods without charging, dunno.

I suspect two minutes will be fine though but it really would be nice to get some expert advice around this as I really prefer the Eco mode if possible - on variable days toward winter it's really useful.
