2.3 Power Meter Wiring

The electricity meter should be mounted and connected at the grid transition point
(feed-in point) so that it can measure the grid reference and feed-in power. Alpha ESS
currently provides 4 different power meter solutions:
ADL-3000: three-/ single-phase meter (with or without CT)
SM60A: single-phase meter
Backup Box: three-/ single-phase meter (Contain off-grid switching and load
management)
ACR10R: Three-phase CT electric meter
