Meter Solutions for SPH/SPA All-In-
One System in Different Scenarios
SPH/SPA 3000-6000TL-HUB/AUB All-in-One supports multi-scenario meter solutions.
Customers can choose the corresponding meter solution according to different
installation scenario requirements. If the CT cable length is less than 10m, we use the
built-in smart meter solution by default. If the CT cable length exceeds 10m, we can
use an external meter and CT solution. If there is an AC-Couple system, we can use
second meter solution.
