The Charge Time Screen gives options for the charging rate. But is it just using the selection (say 6 Kw or 3 Kw) to calculate & display the estimated times-to-charge-level in the Charge Time Screen; or to actually limit the external charger supply to 3 Kw or 6 Kw? I suspect the former rather than the latter ...... In which case .....
Is there a means to limit the rate-of-charge or will it be determined by the maximum rate that the external charger (a home wall-mounted 32 amp supply outputting a maximum of 6.6 Kw in my case) outputs limited only by the Leaf battery temperature-control BMS?

My issue is that the house solar panels inverter has a 6Kw conversion limit, meaning that if the Leaf is drawing 6 kw and the house is drawing another, say, 2kw then the solar power is being supplemented by the grid. The inverter can only suck 6 kw from the solar panels and/or house batteries, even if they're capable of producing/outputting more than that.
As the solar is a daytime supply, charging the Leaf from the solar panels can only be done during the day. But if the grid is also being called on to supply more e to the house&car than the inverter can handle, the grid charge-rate is a daytime rate rather than the nighttime rate of around 1/3rd the price. Poof!
At present, the only way I can limit the Leaf e-suck from the solar/batteries/grid is to use the granny charger. This isn't so bad (I only want to charge the Leaf from, typically, 40% charged to 65% charged) but seems a waste of that nice (and much faster) wall charger.
How, then, to limit the wall charger output to, say, 3kw instead of 6kw?
It's already a bit of a PITA having to use the timer to limit the charge-to amount to 60% or so.
