Avanco and PVPower DC isolator safety advice

The Queensland Government has warned that some isolators used in solar electricity systems have an internal fault that can lead to overheating and fires.

How do I know if I have a defective product?

The defective brands and models have been sold since January 1, 2012.  They include:

  • Avanco branded DC isolators (model numbers AV/DC4P25A, AV/DC2P25A, AV/DC4P25AUB, AV/DC2P625AU, AV/DC2P25AU, AV/DC2/2P25AU, AV/DC2/2P125AU, AV/DC4P25AU, AV/DC4P25AUS, and AV/DC4P25AUT)
  • PvPower branded DC isolators (model number XPDCISO1000V32A).

The isolators are a dial with a red switch with a yellow background around the switch. Avanco brand switches have the brand on the front.  Other defective isolators will look similar but may not have a brand name on them.

What should I do if I have these products installed?

If you have these isolators installed you should shut down your system immediately. Most solar systems have the shut down procedure listed near the inverter or main switchboard.

If you are unsure, check your operating manual or invoice, or call your installer.

Do I need an electrician to shut my system down?

Your personal safety must be your highest priority.  Please take care not to place yourself in danger while attempting to shut down the system, particularly if your switch is on the roof of your home.

You do not need an electrician to shut the system down. However, you should seek assistance if you are unsure of how to safely carry out the shut down procedure. Once the system has been properly shut down it is electrically safe.

What do I do once the system has been shut down? 

You should arrange for the faulty product to be replaced urgently. 

If you have the PVPower brand you should contact DKSH or your installer. The recall and contact details for DKSH can be found at: www.recalls.gov.au/content/index.phtml/itemId/1056490.

If you have the Avanco brand you should contact Advancetech Pty Ltd or your installer.  Advancetech can be contacted on 1800 356 353 or visit www.advancetech.com.au.
