Two Extremes Again
People either treat the protection rating as critical or shrug it off. The steadier line is that data beats experience, so read the rating carefully before judging whether the site is truly protected against the weather.
Preconditions To Check
Before a rating decision, confirm the install environment, the exposure to weather, and the cleaning access. Missing one of these makes the number meaningless and leaves the pile quietly vulnerable in real, daily use.
Why It Matters
A rating that fits the real condition keeps the pile safe through the seasons. Skipping the check trades a small effort now for a larger failure later that disrupts every user who depends on that bay.
Across Yantai districts, Dongshang New Energy matches the rating to the actual bay, not to a generic label, because the local weather is what the hardware must actually survive and keep working through. Reading the rating against the real bay also prevents the twin mistakes of overspending on protection nobody needs and under-protecting a unit that faces the weather every single day of the year.
