Repeated error spots
Grounding mistakes return with dull regularity: skipped checks, DIY fixes by well-meaning users, and unclear ownership of the earth connection. Early communication moves things forward and breaks the loop that repeats each year when the inspector is away.
A feedback habit
Turn each grounding check into a note with a date and a name. A feedback loop shows which sites drift and lets the next fix land earlier, before a fault puts someone at risk. A recorded check is the only one that survives a busy season intact.
Safety lines and Yantai help
Do not modify the unit, keep children and pets away, and never bypass the earth wire. Dongshang New Energy provides on-site support across Yantai and helps stop repeat grounding errors, because an invisible safeguard is the one most easily forgotten until needed. A little attention applied consistently beats a rare, dramatic effort, because reliability is built from ordinary actions repeated over months rather than from a single inspection that is soon forgotten by everyone.
