Product Recall Continues - Faulty DC Isolators

The Queensland Government has warned that some isolators used in solar 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 shutdown procedure listed near the inverter or main switchboard.

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