Hello, is it bad for any of these power stations to be letting them drop to 0% or is it good? Does letting them drop to 0% damage them somehow?
Also, I noticed the charging cord that came with the power station is nice and thick, which I like. However I was wondering if we have another charging cable that is similar enough if we could use that?
Or is it recommended to use only the charging cord that came with the box to charge these power stations?

I do not recommend discharging to 0% frequently in daily use;
however, in the case of battery calibration, it is necessary to charge to 100% via AC and then discharge to 0%. Calibration should be done once every 2-3 months. It is recommended to use the standard cables included in the packaging for charging.
Also possible via AC AND PV?
Or really ONLY via AC (then I must switch off my PV panels).
you’re supposed to drain them to zero and have the machine shut off, once every 6 months or so. There should be no need to do it any more than that.
Of course it’s no problem. 
I use my AC180 to boil the kettle for tea & coffee so it goes down to 0% most days until it’s recharged the following day.
So this is bad? What would you say is the safe lower limit of charge to keep it healthy long term? I assumed lp4 batteries could be discharged and recharged for 3000 cycles.
switch off solar at night/or cover, then ac charge to at least 20% then add the solar.
