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
2.3.1 Meter SM60A (If Applicable)
2.3.2 Meter ADL-3000 (If Applicable)
2.3.1.1 SM60A connect (with meter plug), if applicable:
2.3.2.1 Single-phase in house
2.3.1.2 SM60A connect (with meter plug), if applicable:
