Chinglish MPPT controller datasheet

[pvc]

Hi! I am currently working on some diagnostic/control software for my MPPT solar charge controller. I am having difficulties deciphering whatever authors of this datasheet could possibly mean. Full document is available here. Parts marked in yellow are most troublesome. As non-native English nor Chinese speaker, it is quite confusing to me. Any help appreciated.

The only one I'm fairly sure about is the last one. I believe D2D stands for "dusk-to-dawn".

As for the rest... yikes.

@D14, I assume 365 is one whole year?

D12... percentage of rated voltage?

Could D7 & D6 divide a certain period of time into respectively 6 and 5 equal parts?

D3... maybe a timer that turns the load off after a fixed period?

...my brain hurts now.
