Schneider Electric Square D Recall Notice

A small number of Your Energy Solutions solar customers may be affected by a recall from Schneider Electric for the Square D General Duty Safety Switch, also known as an AC Disconnect, as pictured below.

You may have received the following letter from PG&E:

Where is the AC Disconnect? (not everyone has one)

It is typically installed near your Main Electrical Panel, Utility Meter, or PG&E SmartMeter. The unit is out and exposed and not hidden behind any cover. The unit is large and easy to find.

Not everyone has this unit installed. If you don’t have it installed, then your solar system is not affected by this recall and you may disregard this notice.

However, if this unit was installed, please continue.

What is the AC Disconnect’s purpose?

On the AC Disconnect, there is a lever on the right side of the unit.

By pulling the lever down, it will “break” the circuit between your solar system and your home, causing your solar to stop producing electricity. When pulling the lever back up, solar production will resume after 15-20 minutes (the solar system needs time to “wake up”).

In concept, this unit is similar to a light switch. When turning off a light switch, you break the circuit causing the light to turn off. When turning the light switch back to on, the circuit is re-connected and the light turns on.

Many California cities, but not all, require this AC Disconnect switch to be installed on solar systems.

What is the issue?

A small number of units manufactured between 2014 – 2018 have a malfunctioning lever. If the lever is pulled down, the circuit doesn’t “break”. Your solar system will continue to produce electricity.

It is like turning off a light switch, and the light remaining on.

How can I tell if my AC Disconnect is affected?


PG&E Customer Method (recommended, also see video below)

This test is written specifically for PG&E Customers. If you are not a PG&E customer, please scroll down to the Alternative Method.

Perform this test during the middle of the day when the sun is out (around 11 AM – 2 PM). Minimize electric use during the test. For example, don’t have the dryer running during the test.

  1. Look at the screen of the PG&E SmartMeter. On the bottom of the screen, you will see two black dashes. Verify that these dashes are moving to the left, indicating that your solar system is producing electricity and is sending extra power to the grid.
  2. Pull the AC Disconnect down, which sets the AC Disconnect to off and turns off your solar system’s production. See picture below for how the AC Disconnect looks when in the “Off” position.
  3. Look back at the two dashes and check weather they are still moving to the left or are now moving to the right.

If the dashes start moving to the right, then your AC Disconnect is not affected and your solar system is unaffected by this recall. Remember to pull the AC Disconnect back up to resume solar production (it may take up to 30 minutes for solar production to resume).

If the dashes are continuing to move to the left, there may be an issue with your AC Disconnect. Please contact us immediately to determine the next steps.


Alternative Method (click to expand)
  1. After the sun sets, pull the AC Disconnect down, which sets the AC Disconnect to off and turns off your solar system’s production. See picture below for how the AC Disconnect looks when in the “off” position.
  2. Wait until about 11 AM the next morning and log into your solar system’s motoring portal. Check whether there is solar production for the day.

If there is no solar production, then your AC Disconnect is not affected and your solar system is unaffected by this recall. Remember to pull the AC Disconnect back up to resume solar production (it make take up to 30 minutes for solar production to resume).

If you do see solar production, there may be an issue with your AC Disconnect. Please email SquareDNotice@yourenergysolutions.com immediately to determine the next steps.
