Collection: Labels for Solar PV Systems

Pack containing labels needed for a typical domestic solar PV installation.

Dual supply labelling should be provided at the service termination, meter position and all points of isolation between the PV system and supplier terminals to indicate the presence of on-site generation and indicating the position of the main a.c. switch disconnector.

It is recommended that Inverters carry a sign stating "Inverter - isolate a.c. and d.c. before carrying out work"

Where long cable runs are necessary (e.g. over 20m), labels should be fixed along the d.c. cables.

Connectors readily accessible to ordinary persons shall be of the locking type, requiring a tool or two separate actions to separate and shall have sign attached that reads: 'Do not disconnect d.c. plugs and sockets under load'.

The switch must be labelled as 'PV array d.c. isolator', with the ON and OFF positions clearly marked. Switch enclosures should also be labelled with 'Danger - contains live parts during daylight'.

The d.c. junction box must be labelled with: 'PV array d.c. junction box, Danger contains live parts during daylight'.

This switch shall clearly show the ON and OFF positions and be labelled as 'PV system - main a.c. isolator'.

For use to identify the solar PV system generation meter.

To ensure the Fire and Rescue Service are aware that a PV system is installed on the roof, the following sign shall also be fitted:

Used in systems incorporating energy storage systems (including batteries and inverter/chargers) with grid connected solar photovoltaic systems in a building. This should be fixed:
a) at the origin of the electrical installation;
b) at the metering position, if remote from the origin; and
c) at the consumer unit or distribution board to which the AC supply from the inverter is connected.
