Repeated shocks during a solar backup project led one DIYer to a dangerous grounding problem. The homeowner believed the breakers were off while working in a panel connected to a well and an inverter.
Here's what to know
The issue, described in a Reddit post, was eventually traced to an inverter ground connection that wasn't fully seated.
"I was wiring up a critical-loads panel that includes my well. Part of the panel was live from the inverter, but all the branch breakers were off," the original poster wrote.
In a follow-up comment, the original poster explained, "A screw on an aluminum bus bar, I must have forgotten to screw it all the way down when I was hooking everything up. It's a copper 6ga 3wire with a 12ga ground."
That detail helped explain why the problem stopped once they tightened the inverter grounding point. Before locating the loose connection, they had noticed the well ground arcing against the ground bus.
Grounding problems are especially serious in solar-and-battery systems, where inverters, backup loads, and multiple power sources can make troubleshooting far more complicated.

More background
Solar backup can lower utility bills, provide cleaner energy, and keep essentials such as a well pump running during outages. Setups like this also make installation quality just as important as the equipment itself.
A loose ground can create shock hazards, damage equipment, and make a system much harder to diagnose. That means mistakes can cost more than convenience — they can also chip away at the financial benefits people expect when investing in home electrification.
If you're considering rooftop panels, EnergySage offers free tools that let homeowners curate competitive bids from local installers without sharing contact information unless they choose to move forward with one. That can make it easier to compare trusted local options before taking on a major home energy upgrade.
What can be done?
Turning off breakers should be paired with confirmation from a reliable meter. Careful attention to ground connections and properly torqued terminals can also help reduce the risk of dangerous surprises.
