When using scheduled charging of my batteries overnight in the winter when the electricity tariff is cheaper and day time solar production isn't great, how efficient is the process of taking electricity from the grid and storing this in my Pylontec batteries, through the MultiPlus 48v, 3000VA, 35amp inverter? How much loss is there, 5%, 10%, 20%...? And a second part of the question, how efficient is the process to re-invert 48v back to 240v when I start using power from the batteries again?
It seems the electricity consumed from the grid for scheduled charging isn't recorded anywhere other than my mains electricity meter.
Thanks for any help.
