Batteries charged to 163%!

Never seen this before but, between 00:55 and 01:50 this morning the GivEnergy Cloud reports that my batteries were charged to 163%... So, I'm assuming that this is linked to the clocks being set back at 02:00 as the percentage just before this period was at 81%... Is this normal when the clocks change (we haven't had the system for long enough to notice the last time change)?

It probably is. Some odd, random things can happen or be reported when the clocks change. For me, it has meant the weekly report does not work.
