The Sunny Central CP XT is an SMA central PV inverter family that turns DC from the PV array into grid-compliant AC, which an external medium-voltage transformer downstream then feeds into the utility grid. The family includes the SC 500CP-10, 630CP-10, 720CP-10, 760CP-10, 800CP-10, 850CP-10, 900CP-10 and 1000CP-10. Production version E7 ships with OCU and DSP firmware 02.00.01.R. The enclosure is rated IP54 for indoor or outdoor use. The inverter is classified Class 4C2 under EN 60721-3-4, so it can run in a chemically active environment. Only operate it with a suitable MV transformer that is designed for the inverter's pulsed-mode voltages. Connect no more than one inverter per transformer winding, and do not ground the neutral on the low-voltage side. The maximum voltage to ground is plus or minus 1450 V for the 500 to 800 CP XT models and plus or minus 1600 V for the 850 to 1000 CP XT models. With the optional Q at Night hardware, the inverter can supply reactive power when there is no DC voltage. You turn this on with a parameter. Communication goes through the Sunny Central Communication Controller (SC-COM). The family works with the optional SMA Hybrid Controller and with Sunny WebBox over SMA-NET. Follow ESD protection rules and wear PPE. Do not open the unit in rain or above 95 percent humidity, and do not change grid management settings without approval from the grid operator.
