I discovered that the ECO mode that was supposed to be highly configurable is limited in such a way that it is useless for my fridge. It appears to power on and do some internal things before deciding to run the inverter. So far I have seen it run inverter at around 30, 60 and 90 watts and it always takes 6-7 seconds before starting inverter if it feels it needs to.
The longest seek duration I can set in the ECO mode config is 5 seconds.
I feel that these arbitrary limitations are preventing a good use of this inverter. The 64s interval is probably ok, but if I were able to set the seek interval to 8 seconds to be compatible with this fridge that would mean a 8/64 duty cycle reducing the loss by less than 12%. If it was possible to push this interval to 300 seconds I would reduce it to 8/300 or 2.7% which would be much better.
(I know there are some things running while in sleep mode so not a full saving possible, but still a lot better.)
Could we please have a little more flexibility here? Maybe a custom/advanced mode allowing entering the values instead of sliders so the normal interface can be kept simple?
