The Sunny Central CP-US is a family of SMA central PV inverters for the US and Canadian markets. The family covers the SC 500CP-US/CA, a 600V version of the 500CP-US/CA, and the 630, 720, 750, 800, 850 and 900CP-US/CA models. SMA lists this family among its past Sunny Central inverters, and its manuals are in the archived section of the SMA download area. The Sunny WebBox manual lists all Sunny Central devices under its SMA-NET communication setting. The SMA Hybrid Controller data sheet lists Sunny Central inverters as optional devices. According to SMA safety training for Sunny Central inverters, the DC link capacitors can stay charged after shutdown, so test for zero voltage between the DC switch and the inverter stacks. Before working inside the unit, isolate, lock out and test both AC sources (the grid and the auxiliary supply) and the DC source. Never pull DC fuses under load, because this can cause an arc flash.

c2 drafted · lead Inverter

review note: support check: partial - Page lists CP-US/CA as Sunny Central inverter manuals, implying inverter, but no explicit statement of component type.

c3 drafted · lead Sunny WebBox

The WebBox manual lists all Sunny Central devices under its SMA-NET communication setting.

review note: support check: partial - WebBox SMA-NET setting lists all Sunny Central devices, implying compatibility, but CP-US is not named specifically.

c4 drafted · lead SMA Hybrid Controller

The Hybrid Controller data sheet lists Sunny Central inverters generically as optional devices it can work with.

review note: support check: partial - Hybrid Controller lists Sunny Central generically (and CP-XT), not CP-US specifically.

has_hazard

c5 drafted · lead Stored energy in capacitors

SMA safety training for Sunny Central inverters in general: the DC link capacitors can stay charged after shutdown, so measure between the DC switch and the inverter stacks.

c6 drafted · lead DC arc flash

SMA safety training for Sunny Central inverters in general: arcing when DC is disconnected under load, for example by pulling a DC fuse.

c7 drafted · lead Electric shock

SMA safety training for Sunny Central inverters in general: there are two AC sources (the grid and the auxiliary supply) and the DC sources, and all must be isolated and tested.
