SMA Sunny Tripower STP20000TL-US-10 20KW Inverter

SMA, Sunny Tripower 20000TL INVERTER ONLY, Grid tied inverter, 3-Ph, 20kW, 277/480VAC, 60Hz, 600/1000VDC, with installed SWDM-US-10, (Use with DC Disconnect: CU 1000-US-10), STP20000TL-US-10

The Sunny Boy 3000TL-US represents the next step in performance for UL certified inverters. Its transformerless design means high efficiency and reduced weight. Maximum power production is derived from wide input voltage and operating temperature ranges. Multiple MPP trackers and OptiTrac™ Global Peak mitigate the effect of shade and allow for installation at challenging sites. The unique Emergency Power Supply feature provides daytime power in the event of a grid outage. High performance, flexible design and innovative features make the Sunny Boy TL-US series the first choice among solar professionals.

SMA offers five three-phase commercial inverter options, ranging from 12 kW to 30 kW. All inverters connect to 480 VAC three-phase utility service. The detachable CU1000-US-10 DC connection unit has fusing for both MPPT inputs, and allows for easy swap out of the inverter for servicing. Tripower inverters all feature integrated DC AFCI.

MPPT Circuits and a wide MPPT operating voltage range, combined with a low startup voltage, allows for very high efficiencies. They can be configured for either 600 DC or 1,000 VDC installations. The Tripower inverters can be mounted on the roof, next to the array. This allows compliance with NEC 2014 rapid shutdown requirements without additional components. The optional SMA ReadyRack™ allows for simplified installation of the inverter, combiner, disconnects and cabling on flat commercial rooftops. The ReadyRack must be ordered at the same time as the Tripower inverter and CU1000 combiner/ disconnect, and these ship fully assembled directly to the job site.

Monitoring through the free SMA Sunny Portal can be easily configured, as these inverters come preinstalled with the SMA Speedwire Card. Up to four inverters can be daisy chained together and viewed as a plant. For larger installations, the optional SMA Cluster Controller can be added for plant-level monitoring of up to 75 SMA inverters, and communication to third-party devices through Modbus protocol. The cluster controller enables multiple inverters to be viewed and reported on at the plant level, and enables remote operation of reactive power adjustments as well as remote shutdown of the PV Plant, if required.

NOTE: The Cluster controller requires a 24 VDC power supply, which is not included.
