Isolate battery power supplies

Isolation of uninterruptible power supply systems

If an uninterruptible power supply system is providing back-up to a whole building, there should be a cut-off point, usually located near to the isolation point for the mains power.

Isolation of battery storage for solar PV systems

If there is solar PV system battery storage, there should be a cut-off switch for the batteries near to their location. Remember that the DC power may still be going to the batteries.
