Hi.
I have GivEnergy battery only system.
Electricity board are going to come and replace the mains wire and fuse box to the house to larger capacity.
Do I need to do anything with the battery when they disconnect the meter/fuse box? Or can I just leave it attached as normal?
Thanks in advance
When we had the service head replaced, the electric board were not interested in turning anything off, I'm guessing as they were playing with an always live end anyway.
So there's no risk of damage to the battery by them disconnecting the mains wires?
DocD Does the battery provide cover during power cuts (eg AIO with gateway) ? It might not like having power rapidly switching on/off when attaching/detaching live cables.
Do you have an isolate switch after the meter ? Switching off there should be sufficient, and I think would still allow the battery to power the house (depending on exactly how things are wired).
The engineers will do whatever they have to do. No real issues to worry about IMO.
When we had our looped supply disconnected & main fuse upgraded our DNO (National Grid) only had the supply off for 20mins. They also installed a separate incoming isolator in the outside meter cupboard which I believe is a requirement for all new electrical supplies.
The only thing you may have to do is to reset the battery - if it has a reset button on it it. Ours has a reset button (2 x 9.5kWh Gen 2) but bot restarted OK after power cuts & disconnections without any trouble.
Personally I'd turn my system off, but as others have said sounds like it doesn't matter
However one thing to note - the CT clamp that monitors the mains usage...
Make sure you have a photo of where it is (which wire it is on) and which direction the arrow is pointing in.
No guarantees that the people will put it back in the right place or right way around!
DocD It could be a reasonable precaution to turn your isolator off for the duration of the work but I would not worry too much. You have no control for instance when there is a power cut and sometimes one can get multiple switching in and out as the grid tries to recover. The Givenergy kit will be able to deal with the situation.
