SMA Solar Technology is showcasing an expanded range of ‘Sunny Boy’ TL-US inverters with ‘Secure Power Supply’ at Solar Power International. The higher power ratings of the new Sunny Boy 7000TL-US and 7700TL-US are designed to meet the needs of large residential PV projects and are able to provide daytime power in the event of a grid outage.

Problem

Large residential PV projects boarder the need for commercial rooftop balance of system (BOS) components and configuration, increasing installation costs and limiting the ability to optimise the system for best performance and lowest LCOE (Levelized Cost of Electricity). Offering a wide range of power classes, including two models specially designed for service-constrained systems, offers installers the right fit for virtually any residential PV application.

Solution

The Sunny Boy 7700TL-US is specially configured for homes with 200-amp service panels, allowing solar installers to maximise system size and energy production without expensive service panel upgrades. Each model of the Sunny Boy TL-US series is equipped with the popular Secure Power Supply feature, which addresses the needs of grid-tied system owners during power outages. It makes it possible for the inverter to provide up to 1,500W of daytime standby power when the grid is down for charging laptops, cell phones and more, without the need of additional, costly batteries. The inverter’s shade-tolerant ‘OptiTrac’ Global Peak MPP tracking algorithm and two MPP trackers provide increased energy production for complex arrays with partial shading or multiple roof orientations.

Applications

The Sunny Boy 7700TL-US is specially configured for homes with 200-amp service panels, allowing solar installers to maximize system size and energy production without expensive service panel upgrades.

Platform

Additional features of the Sunny Boy TL-US series include a transformerless design that ensures high efficiency and reduced weight, and integrated DC AFCI functionality meeting NEC arc-fault protection requirements and certified to the UL 1699B standard. It also provides easy monitoring and control features, including a large graphic display and the optional plug-and-play Webconnect data module for easy system monitoring with direct data transmission to Sunny Portal. With high CEC efficiencies, a wide input voltage and extended operating temperature ranges from -40 to 140 F, the Sunny Boy TL-US series offers enhanced power production under a variety of conditions. 

Availability

October 2014 onwards.

This year’s EV World Congress will hold a special role, not only as the first live EverythingEV event in over a year – a chance to renew your connections and re-engage with the EV sector face to face – but also as a chance to share insight and inspiration as world starts to look towards move on post COVID towards hitting ambitious decarbonisation goals in 2030 and beyond. As ever, we will be bringing world leading organisations, cities, and technology providers to the UK to inspire EV innovators, and delve into the challenges facing the sector as the UK looks to revolutionise road transport.

Utility-scale solar is evolving, shaped by higher power modules and demand for increasingly lower levelised cost of electricity (LCOE). Those trends are also changing project requirements elsewhere, with inverters capable of delivering high power density and power capacity in strong demand. In this webinar, FIMER will detail how its innovative high-power, multi-MPPT string inverter and modular conversion solution can both meet those demands and transform the utility-scale solar sector for the better.

The race is on but we need to sprint… With global climate talks fast approaching and time running out to prevent the most disastrous impacts of climate change, now is the time to act. The Summit will explore the opportunities that emerge from taking action on climate change and provide a clear pathway forward for governments, citizens and companies. Taking place just 10 days before the G20 meeting in Rome, on 30-31 of October, and in the lead up to the critical COP26 meeting in Glasgow from 31 October–12 November, this event will be instrumental in influencing ambitious global action.

The solar tracker market continues to mature at breakneck speed, with designs and component selections becoming ever-more complex in the pursuit of better project economics. But a more simplistic design could deliver a triple benefit of lower Capex, EPC and Opex costs. This webinar will set out the ideal single axis tracker design for utility-scale solar farms. The design leapfrogs from decades of experience, with a comprehensive understanding and attention to the three cost structures of Capex, EPC and Opx. Sun and Steel Solar has prototyped a single axis tracker designed to deliver up to US$0.03/W in real savings compared to existing single axis trackers on the market. That’s US$30 million for every gigawatt deployed.

The 10th edition of the famous Metallization and Interconnection Workshop, MIW2021, will take place in the Thor Central venue in Genk, Belgium, on Monday, November 15, and Tuesday, November 16, 2021 as a face-to-face meeting. We are longing for direct exchange of knowledge and ideas after a long time. Hopefully you can be part of it! But of course, the organizors will keep an eye on the evolution of the Covid pandemic. It will be assess carefully, whether the workshop can be held without major risks or excessive restrictions. We are looking forward to exciting talks, discussions and meetings and to welcoming you in Genk!
