Good one @Bandersnatch
We will also be going in the future off-grid, but that said, we will keep the PEA meter just as a backup.
I understand your backup is now the V2L (Vehicle to Load) but in eventualities it helps to also be able to switch to PEA and for 30 THB +/- per month, (which it costs to keep the PEA meter (standard service charge)), it's IMHO worth it.
