What PV system types (single-phase/three-phase) is the Wi-BR compatible with?

The Wi-BR is compatible with both single-phase and three-phase PV systems.

• For single-phase systems: Connect the Wi-BR to the L (live), N (neutral), and PE (ground) wires as shown in the manual’s Figure 4-1.
• For three-phase systems: Connect the Wi-BR to the N wire and any one of the three L wires (L1, L2, or L3) (per Figure 4-2 in the manual).

Note: The wiring diagrams in the manual use the European TN-S grid system as an example and are for reference—adjust based on local grid standards.
