5 Wiring
5.1 Preparation before Wiring
1. Ensure voltage values and polarities are correct.
2. When grounding the solar array, an isolation transformer is required due to
the RPI H3A / H4A /H5A not having galvanic isolation between the DC-input
and AC-output.
3. The ground fault detection is a fixed internal setting. It cannot be modified.
4. Whole system wiring can be seen in Figure 5-1 and Figure 5-2.
5. Please refer to Figure 5-1 for connections. Inverter can accept DC inputs in
parallel (2 MPP trackers/ 2 parallel input).
