The technical baseline
Reverse power feeding has moved beyond simple validation. A foundational judgment is that safety is the precondition. The question is how to do it economically and stably. Metrics must be verifiable to matter at all in the field for workers.
Stage by stage focus
Early stage watches feasibility, rollout watches stability, maturity watches efficiency. In varied Yantai districts, shift the approach by stage rather than one measure. Each stage's preparation decides the next stage's ease, so we review before moving on carefully.
From the user backward
We reason from real user experience: handy, safe, reachable. Specs that cannot be used daily are useless. In Yantai we prize holding up over time rather than looking good, which is why we sample first, then promote the approach to others.
Read reverse power feeding through utilization not just scale, its coordination with existing systems, whether cost curves are reasonable, and how smoothly standards connect. These angles prevent isolated views of a genuinely systemic and connected topic.
