This manual describes the Sungrow PVS-8M/PVS-16M PV array combiner box, a device that consolidates multiple photovoltaic strings before they connect to an inverter. It explains the system architecture, safety precautions, and the benefits of using a combiner box in large PV installations.
Key sections cover safety warnings, mechanical and electrical installation procedures, communication parameter settings, fault diagnosis, and a full set of technical data such as voltage range, current capacity, IP rating, dimensions, and RS‑485 communication details. This manual is written in Chinese.

Only professional electrical or mechanical engineers should perform installation and wiring, the DC breaker must be opened, and internal parts must not be touched; all work must follow local standards.
The product has a 12‑month warranty, subject to contract terms.
Use shielded twisted‑pair cable, provide a single‑point ground for the shield, and terminate the bus with a 120 Ω resistor.
Even after opening the DC breaker, all terminals may still carry high voltage; ensure the breaker is fully opened and keep away from live parts.
