Note:
(1). The power factor value indicates the direction of the current. Positive value refers to forward current, negative
value refers to reverse current.
For example, PF=0.98, it means the current is forward flow;
if PF= -0.98, it means the current is reverse flow.
(2). The power sum demand calculation is based on total power = import power – export power.
(3). Total Energy = Import energy + Export energy. For example: total active energy = import active energy + export
active energy
(4). Net Energy = Import energy – Export energy. For example: Net active energy = import active energy – export
