400A Home Group
Link two MAC 3.0 systems on a 400A service panel to coordinate energy dispatch across both systems, reducing grid import and maximizing solar self-consumption.
System Requirements
🔷
Exactly 2 MAC 3.0 systems
Both devices must be on this account
✓ Pass
💻
Hardware version 107 (new MAC)
MAC 3.0 SN-001: v107 · MAC 3.0 SN-002: v107
✓ Pass
🌐
Both devices online
MAC 3.0 SN-001 · MAC 3.0 SN-002
✓ Pass
📡
Same local network
Both devices on 192.168.1.x
✓ Pass
Network latency < 100ms
Current latency: 42ms
✓ Pass
⚙️
Operating mode: Self-Consumption or Backup-Only
SN-001: Self-Consumption · SN-002: Self-Consumption
✓ Pass
Operating Limits
Coordination only works when on-grid. Both systems operate independently when off-grid.
🔒
Supported modes: Self-Consumption and Backup-Only.
🔌
No other loads may be connected to the 400A panel besides the two MAC 3.0 systems.
Installer Confirmation
I confirm that no other loads are connected to the 400A panel besides the two MAC 3.0 systems.
I confirm that dual-MSA hardware has been correctly installed on both systems.
I confirm that the wiring has been completed according to the 400A installation guide.
