DC input power cable

Common outdoor PV cable in the industry

(Recommended model: PV1-F)

• Conductor cross-sectional area: 4–6 mm²
• Cable outer diameter: 5.5–9 mm

2

(Optional) Battery cable

3

(Optional) Signal cable^a

Outdoor shielded twisted pair

• Conductor cross-sectional area: 0.2–1 mm²
• Cable outer diameter: 4–11 mm

4

AC output power cable^b

Outdoor copper cable

• Conductor cross-sectional area: 4–6 mm²
• Cable outer diameter: 10–21 mm

5

PE cable

Single-core outdoor copper-core cable

Conductor cross-sectional area: ≥ 4 mm²

Note a: When the smart power sensor and battery are connected to the SUN2000 at the same time, use a cable core with a cross-sectional area of 0.2 mm² to 0.5 mm².

Note b: The minimum cable diameter depends on the fuse rating on the AC side.
