Sunny Boy 7000TL-22-US Inverter
with Secure Power Supply
The Sunny Boy 7000TL-US-22 inverter, one of SMA’s new series of transformerless inverters represents the next step in performance for UL-certified inverters. The transformerless design means the inverters are high efficiency with reduced weight. In addition, maximum power point tracking (MPPT) is derived from wide input voltage and operating temperature ranges.
Also, an optional Secure Power Supply (SPS) feature enables these Sunny Boy inverters to supply up to 12 A at 120VAC to a single outlet for recharging portable devices or a small UPS directly from the PV array in the event of a grid outage during daylight hours.
Optional RS485 or Webconnect data modules enable web-based system monitoring with the SMA Sunny Portal. These transformerless inverters work with an ungrounded PV array topology so the requirements of NEC 690.35 must be followed, including using PV Wire for exposed array string wiring.
The SMA Sunny Boy TL-US line of transformerless inverters have both ground and arc fault detection per NEC 2011. An input voltage range of 175 VDC to 600 VDC and dual MPPT input dramatically increases module selection and string sizing flexibility as well as better production when parts of the solar array are shaded. A modern graphic display and an integrated DC disconnect switch are included.
Each inverter is covered by a 10-year warranty, which can be extended to 15 or 20 years.
