Hi colleagues
I have a 4 stack Mira HV25 with Mira BMS Battery system, currently sitting on concrete garage floor. I want to place the stack on a purpose made stand -about 300mm high to avoid possible water damage from flood water.
My query is if I turn everything off(following video by Will in this forum) then disconnect all cables , relocate battery stack on stand in same floor position, then reconnect, can I then just start up (again following video) and will the system reboot automatically or are there other issues that might occur?? Or should this be done by an expert. I am reluctant to use the original installer as they were rubbish.
Cheers and thank you.
Shut down/restart advice

You can do exactly that, things to be very mindful of -
take a picture of the batteries and the wiring before you start,
make sure that the batteries are re-stacked in the same order as they were and do not change the dip switch settings.
be careful with the DC cables - you'll have over 200V dc when all of them are wired together
the comms cables are connected from BMS to battery 1 RS485-1, the inter-connects are wired from RS485-2 to RS485-1 on the next battery and repeat until all are connected.
make sure you earth the batteries and connect the earth to the earth connector on the right side of the inverter
