A homeowner hoping to expand a solar battery storage setup ran into a frustrating catch: Buying the hardware may be easy enough, but getting it officially commissioned is another story.
Here's what to know
In Reddit's r/SolarDIY, the original poster said they had a FranklinWH battery for their DIY solar install and wanted to add another. However, they explained that "the company won't commission if I install" a second DIY unit. "What's the best way around this?"
The discussion highlighted a common issue with backup power: Expanding storage later may depend on the first installer or another approved professional.
Still, battery storage is an increasingly popular upgrade because it can store solar power for nighttime use or blackouts, helping homeowners buy less electricity during expensive evening hours and keep critical appliances running during emergencies.
If you're comparing options, it's worth exploring EnergySage for information on home battery storage options, including competitive installation estimates. EnergySage has teamed up with the electrification brand Qmerit to guarantee you get the best price on home battery storage solutions.
What can be done?
In this case, one Redditor said the best path forward may be to obtain a specialized certification. "Just get Franklin certified and commission it yourself," they advised. Doing so seemed easier said than done, though, according to a commenter and the original poster.
"Man I tried to do this and the regional service manager has to call. It's been five months since I submitted the request, and it's been crickets," one person said.
"I did look into getting certified. It's not particularly DIY friendly," the OP added.
