True - but although it's probably not true of the OP, "KA" probably means nothing to most of the people who ask questions in this forum, and an even higher proportion of the 'general public' - and, for the purpose of the discussion the difference between kW and kVAh is of no consequence.
Kind Regards, John
"KA" means nothing to me either....
Certainly the difference between kW and KVAh is very relevant. One is power, the other is energy.
