Brand New in box SMA Sunny boy 3800 TL-US-22 With DC Disconect. SMA Sunny Boy 3800TL-US-22 > 3800 Watt 240 Volt Non-Isolated String Inverter with Emergency Power “Switch not included”. The new Sunny Boy TL-US line of transformerless inverters features high efficiency and reduced weight along with 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. An optional Secure Power Supply feature enables these 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. Optional RS485 or Webconnect data modules enable web-based system monitoring with 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 Sunny Boy 3000TL-US/3800TL-US/5000TL-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. A unique Emergency Power Supply feature provides daytime power even in the event of a grid outage. High performance, flexible design and an innovative feature set make the Sunny Boy TL-US series the first choice among professionals. One of many unique features to the TL-US residential series is its innovative Emergency Power Supply ability. With most grid-tied inverters, when the grid loses power, so does the solar-powered home. SMA’s solution allows daytime energy to be isolated from the grid and be fed directly to the home via a dedicated power socket, providing residents with access to power as long as the PV system generates electricity. As a transformerless inverter, the TL-US residential series is lighter in weight than its transformer-based counterparts, which makes lifting and transporting the new inverter easier than before. A new wall mounting plate features anti-theft security and makes hanging the inverter quick and easy. A simplified DC wiring concept allows the DC Disconnect to be used as a wire raceway, saving labor and materials. Leading monitoring and control solutions. The new TL-US residential line features more than high performance and a large graphic display. The monitoring and control options provide users with an outstanding degree of flexibility. Integrated Zigbee, a wireless communications standard often used for home energy management, and numerous wired options allows for a highly controllable inverter and one that can still be monitored on Sunny Portal from anywhere on the planet via an Internet connection. Whether communicating through Zigbee or SMA’s new wired, plug-and-play WebConnect, installers can find an optimal solution to their monitoring needs. The Sunny Boy 3000TL-US / 4000TL-US / 5000TL-US are transformerless inverters, which means owners and installers benefit from high efficiency and lower weight. A wide input voltage range also means the inverters will produce high amounts of power under a number of conditions. Additionally, transformerless inverters have been shown to be among the safest string inverters on the market. An industry first, the TL-US series has been tested to UL 1741 and UL1699B and is in compliance with the arc fault requirements of NEC 2011. OptiTrac Global Peak, SMA’s shade-tolerant MPP tracking algorithm, quickly adjusts to changes in solar irradiation, which mitigates the effects of shade and results in higher total power output. And, with two MPP trackers, the TL-US series can ably handle roofs with multiple orientations or specific shaded areas. An extended operating temperature range of -40 °F to +140 °F ensures power is produced in all types of climates and for longer periods of time than with most traditional string inverters. What makes these new SMA inverters so exciting? In a pure grid-tie system, when the utility grid goes down, so does your solar array. In the grand scheme of things, this makes sense: imagine if you’re working on the utility grid and you get electrocuted because someone’s solar array is still feeding power into it? On the other hand, it can be a pain to those who’ve invested in solar so they can have power all the time. While this is a great idea, batteries can add an extra layer of complexity to sizing your system. SMA’s TL-US inverter offers another option, allowing you to literally plug your important electronics into an outlet attached to the unit during full daylight. Under what circumstances will the emergency power switch work? If the utility grid is down and you still have full daylight, you can manually flip the switch on the emergency power switch and then plug what you need to power into the attached socket. I’ve heard that this inverter can handle multiple roof orientations. What does this mean and how does it work? From SMA: Traditionally, solar professionals had different ways of dealing with a site containing multiple roof orientations. A string inverter could be used on each roof, a single inverter for both roofs or micro inverters on both roofs. Micro inverters are a good solution since they can take advantage of the module level MPPT to extract the most energy from the losses associated with mismatched roofs. String inverters have been given a back seat to these types of applications because of the perceived mismatch losses that these types of inverters cannot compensate for. SMAs new 3000TL-US/3800TL-US/5000TL-US family will have dual MPPT channels, which will give them the ability to track two different array orientations while reducing the mismatch losses. In fact, you can even use different string lengths on each channel as well as different module types if your design warrants it. Both arrays are processed separately and their outputs combined after the power conversion. This means more harvest from mismatched arrays but with the benefit of using a single string inverter.
