Solar Spotlight: Back Off Gas-Powered Generators, A New Backup is in the House!

A New Jersey family will no longer need gas-powered generators during outages. The installation of SMA’s Sunny Boy Storage with Automatic Backup Unit in their residence will provide them with backup power – and peace of mind – during emergencies.

Financial and environmental reasons moved the Ratliff family to add storage to the solar system at their home. They wanted to be able to maximize self-consumption to take advantage of lower rates with time-of-use billing and avoid the use of dirtier gas-powered generators.

Exact Solar, the installer to whom the family entrusted this project, analyzed its client’s needs and options available to come up with a recommendation of connecting three LG Chem batteries to an SMA Sunny Boy Storage battery inverter with an Automatic Backup Unit.

This fully integrated solution for whole home backup power from SMA offers an AC coupled architecture, which provides opportunities for new PV or retrofit installations, and allows up to three high-voltage batteries connected in parallel to the battery inverter. It also has a 200 Amp rated bus for direct line-side connection to large home electrical panels. In addition, it balances up to five kVA of imbalance across phases, reducing the potential for system interruption during backup mode operation due to imbalanced loads within the home.

“We chose the SMA Sunny Boy Storage because it was the system that was able to give the customer the functionality he was looking for at a reasonable price. The Sunny Boy Storage inverter was able to be connected to three of the LG Chem batteries, which is the amount of energy storage we needed, and the ABU gave the controls necessary to maximize self-consumption for all of the customer’s loads and not be limited to just a critical loads subpanel. As more utilities go to time of use pricing or limit export, I think we will see more and more storage systems being implemented,” said Exact Solar Founder and President Mark Bortman.

The 20.13kW system was commissioned in February 2019.

Why Power+? How to Explain the Solution to Homeowners

Many of our installation partners and Authorized Distributors are excited about the game-changing Power+ Solution. Hopefully, many of you have even received some training via a Solar Academy webinar, or have watched our tech tips on how to install it.

But how do you explain the benefits of the Power+ Solution to homeowners who may not immediately understand it – or perhaps aren’t even sure what an inverter does?  Rather than focusing on technical information, here are a few tips that may help you explain why SMA’s Power+ Solution is the best choice for residential PV systems.

  • Highlight SMA’s proven experience as a #1 global inverter brand, sharing that SMA has 35 years of field-proven experience.
  • Talk about the safety and reliability of the Power+ Solution, including how our solution uses fewer components than competitor solutions, meaning there will be less maintenance involved.
  • SMA’s Power+ Solution produces more power than its competition. This means more savings on power bills for homeowners!
  • Share information about Sunny Portal, our free, mobile-friendly tool that will help homeowners track their system’s performance and ROI.
  • Spotlight SMA as a future-proof choice. With SMA’s continued commitment to developing home energy management technology and exciting partnerships with leading battery brands, homeowners can count on SMA technology as they equip their home to be a smart home of the future.

Power+ Solution

Each of these is highlighted in our special brochure just for homeowners. This is a great tool for you to use when you are talking to homeowners about their residential PV project. To access the brochure, simply click here or scroll down to the bottom of the Power+ Solution page. There, you’ll see a red icon labeled with Download the Power+ Solution brochure for homeowners.

We encourage you to browse our website for additional resources as well, and come back to our blog regularly for more helpful tips and tools.

SMA Redefines Optimization with its Power+ Solution

power-solution-sma

SMA is now taking orders for its new, game-changing Power+ Solution to optimize residential systems. Combining the proven Sunny Boy US inverter with the TS4-R Module Level Power Electronics (MLPE), the new SMA solution cost-effectively optimizes residential PV systems and ensures higher energy yields.

The Power+ Solution will redefine what it means to optimize a residential PV system using MLPE. SMA’s MLPE solution can be applied per module for operational simplicity or selectively for faster installation.

Every PV project has its own unique challenges and objectives, and there is no one-size-fits-all solution in today’s solar landscape. The Power+ Solution enables integrators to apply the technology in a way that optimizes ROI for their individual business model.

The TS4-R module components of the SMA Power+ Solution can be used like traditional MLPEs and satisfy all of the challenges that incumbent solutions address. But unlike traditional optimization, which requires MLPEs on every module even when it’s not needed, the Power+ Solution can also be applied selectively. This reduces installation time, service risk, and ultimately cost. Selectively deploying TS4-R can save up to 90 minutes of installation time per residential system while realizing greater energy production and roof usage, and providing a higher ROI.

Selective deployment is also ideal when it comes to service and O&M. Fewer components mean fewer potential points of failure and less risk, and when service is required, it is simpler.

For integrators opting for full deployment, installation can still achieve significant time-saving.

The module-based DC technology is supplied by the universal TS4 platform, which offers various levels of plug-and-play functionality. The TS4 is available as a factory integrated component through leading module suppliers. It is also available as an add-on, retrofit option exclusively through SMA, and makes any system instantly smarter and more powerful.  Benefits of the TS4 line include module-level monitoring, shutdown code compliance, shade mitigation and increased string lengths.

The TS4 has been engineered to work seamlessly with the Sunny Boy US inverter, which is the fastest PV inverter to install. This allows installers and distributors to realize additional cost savings by reducing the total number of products they must carry. Now, integrators can carry one line of inverters for MLPE and non-MLPE applications, which reduces warehouse space while also improving flexibility when installation requirements change at the last minute.

For data monitoring, module-level diagnostics can be viewed through Sunny Portal – the world’s largest monitoring repository for PV systems.

Installing SMA’s Rapid Shutdown System: Tech Tip Video

RSD_Box_160412

Check out our latest Tech Tip to learn how to properly install SMA’s Rapid Shutdown System.

Why choose SMA’s Rapid Shutdown System? First of all, it’s the most cost-effective way to comply with 2014 NEC 690.12 for states that have adopted 2014 NEC or will be adopting it soon. It will also ensure compliance in those states that have adopted 2017 NEC, until the 2019 80-volt limit goes into effect.

Another major reason to select SMA’s Rapid Shutdown System is that it is compatible with our Secure Power Supply functionality for residential string inverters in case of grid outages – whereas other rapid shutdown systems would eliminate such functionality.

Finally, our Rapid Shutdown System is fast to install. It also fits underneath a module, so you won’t need to extend racking to accommodate it.
