1.Background：
As the global fossil energy (oil and coal) is approaching exhaustion, pollution is becoming more and more serious, and the climate is warming, etc., many countries and regions around the world have successively issued regulations and policies, which have promoted the development of the PV industry.
However, due to the large number and concentration of the PV monitoring circuits, a large number of power distribution room space is occupied.
Acrel multi-channel energy meter has a high level of integration. A single module can monitor 48 circuits, and at the same time, it can also be matched with switch acquisition module to realize the circuit monitoring of PV system.
2.Project Brief：
One PV system company in the Netherlands that provides PV systems for a wide variety of buildings.
In the PV monitoring system of the customer, the current situation of more than 300 loops need to be monitored at the same time. These loops are centrally in the distribution room. In order to collect information more effectively, the customer chooses the product of AMC16Z-FAK48, so as to complete the monitoring of the circuit without adding cabinets.
