A Texas homeowner looking to install discounted Powerwall batteries encountered a costly hurdle. His contractor wanted about $3,000 in labor to connect the equipment.

A missing component in a used disconnect switch added another complication.

Here's what to know

The switch was purchased used on an online marketplace, and a neutral bonding piece required by the project's electrical diagram was missing. The missing part was on order, and the breakers were already installed, according to the homeowner's update on Reddit.

"Looking at about $3k in labor. Does that sound right? The powerwalls are already in place and ready, just need to hang disconnect and gateway and wire it up. I think the expertise here is the connect to the meter, which is fair enough," the original poster asked.

Battery storage can protect your home during outages and provide more energy independence. It can also help lower energy costs, depending on electricity rates and how the battery is used.

Homeowners can explore EnergySage for home battery storage options, including competitive installation estimates. EnergySage has teamed up with electrification brand Qmerit to help homeowners get the best price on home battery storage solutions.

More background

The homeowner did not disclose how much they paid for the scratch-and-dent Powerwalls. Only the installation cost was listed as a point of comparison. One commenter shared their own installation experience: "One PW and Gateway was around $5K CAD for me."

That figure, however, was in Canadian dollars, and the commenter did not provide an itemized breakdown. That makes a direct comparison with the Texas homeowner's labor estimate difficult.

Design review and approval, along with disconnecting and reconnecting power, generated separate utility charges for that commenter. They cautioned that a contractor had no control over those additional expenses.

Another commenter shared their experience with a self-install: "I just spent $3750 for an entire Solark 15k, NIB, self installed."

The comment section didn't offer much for a like-for-like comparison, but the original poster noted that they would pursue multiple quotes.

What can be done?

An independent master electrician agreed to inspect the job as the homeowner kept searching for installation help. The electrician was located about a mile from the home.

This type of system installation was new to the electrician.

There is no confirmation in the thread that the batteries were connected or operating. In a later update, the homeowner said an electrician they knew from a large commercial job had agreed to visit after the two ran into each other at Home Depot.

For homeowners considering a smaller backup option, Pila is another company offering strong battery backups. Pila's plug-and-play batteries are priced at a fraction of what a whole-home backup system would cost.

"Yeah, I think the rates I am getting are about right. Thanks for posting!" the homeowner concluded.
