Warning Multiple Energy Sources – Turn Off All Isolators to Isolate Inverter

This warning label alerts electricians and service technicians that the inverter is connected to multiple energy sources and that all relevant isolators must be addressed to complete the inverter isolation process. It is designed for solar, battery and hybrid systems where a single switch cannot be assumed to de-energise the equipment.

For multi-source inverter systems

Suitable for photovoltaic installations, battery energy storage systems, hybrid inverters, backup systems and off-grid equipment where AC and DC sources can be connected simultaneously.

Why all sources need to be considered

An inverter may receive energy from the grid, PV arrays, batteries or another supply. Turning off only one isolator can leave another source connected. Clear warning identification helps personnel recognise the need to identify every relevant isolation point before maintenance or service work.

Use with the approved shutdown procedure

The exact number and location of isolators varies between installations. Confirm the complete isolation sequence against the electrical drawings, inverter documentation and commissioned system before relying on the label.
