ForeverPure provides free preliminary design for residential and commercial solar projects worldwide. SMA Sunny Boy SB 7700TL-US-22 7.7kW Grid-Tie String Inverter 208/240V With DC Disconnect and Secure Power Supply. The top 3 features of the tl-22. Secure power supply, dual mppt tracking, and opti trac global peak. Secure power supply is the option to use up to 1.5kw of power when the grid is down. Dual mppt is what most other inverters have (two channels with four strings possible). Mainly opti trac global peak finds the global peak of power when there is shading. The sweeps are generally every six minutes. This is very effective when you have a wide voltage range like the tl-22. So the enphase micro or solar edge optimizer may provide, if any, about 2% more power compared to a string inverter! And if that was true, it would only be for the shaded module(s). That is really not significant and micro inverters are more expensive compared to the TL-22. 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 Secure 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. A new generation of innovation The new Sunny Boy TL-US residential series has yet again redefined the category. Transformerless design The Sunny Boy 3000TL-US / 3800TL-US / 4000TL-US / 5000TL-US / 6000TL-US / 7000TL-US / 7700TL-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. Increased energy production OptiTrac Global Peak, SMAs 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 complex roofs with multiple orientations or string lengths. 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. Secure Power Supply One of many unique features of the TL-US residential series is its innovative Secure Power Supply ability. With most grid-tied inverters, when the grid goes down, so does the solar-powered home. SMAs solution provides daytime energy to a dedicated power outlet during prolonged grid outages, providing homeowners with access to power as long as the sun shines. Simple installation 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 be monitored on Sunny Portal from anywhere on the planet via an Internet connection. Whether communicating through Zigbee®, RS485, or SMAs new wired, plug-and-play WebConnect, installers can find an optimal solution to their monitoring needs.
