Top managers in Germany like to toss around the phrase, “growing pineapple in Alaska.” Among them is former RWE CEO Jürgen Großmann, who has joked that subsidizing solar energy is equally unlikely. Although nobody is actually growing pineapple in Alaska yet, solar energy is gaining ground in that remote U.S. state.
Commissioning a new lithium-ion battery within a Sunny Island system takes only minutes. In this Tech Tip video, the SMA Solar Academy demonstrates the simple commissioning procedure for a Sunny Island system with a battery that uses an external battery management system, or BMS.
You’re on the way to pitch a potential customer on the benefits and value of installing solar on their home. Great! Like SMA, most component manufacturers have likely sent you varying homeowner leave behind materials to, well, leave behind with the homeowner after your meeting.
SMA’s highly anticipated Rapid Shutdown System is now available and ready for pairing with the latest Sunny Boy-US and TL-US inverter families. Engineered for use with SMA’s inverter lines featuring Secure Power Supply, this simple, reliable and cost-effective solution achieves all requirements for 2014 NEC 690.12 rapid shutdown.
Oversizing a PV array, also referred to as undersizing a PV inverter, involves installing a PV array with a rated DC power (measured @ Standard Test Conditions) which is larger than an inverter’s rated AC output power (i.e. DC @ STC > AC). It can be a valuable tool for system designers seeking to deliver a maximum amount of energy at a lowest possible specific cost. Reasons for over-sizing PV arrays and important factors to consider are summarized below.
College of the Atlantic in Bar Harbor, Maine is taking its classroom outside for serious hands-on know-how in its renewable energy practicum program. Lead by Professor Anna Demeo, Ph.D., students learn the ins-and-outs of building design and how to incorporate renewable energy during the planning stages.
SMA’s ReadyRack™ forever changed commercial rooftops by creating an all-in-one inverter, rack and disconnect solution for immediate rooftop placement and system connection. Now in its second generation, the improved ReadyRack features a smaller footprint, lighter per-unit weight, and reduced cost, making it an even more versatile solution for today’s crowded commercial rooftops.
The long journey from Hoboken, New Jersey to Irvine, California was worth the effort for Stevens Institute of Technology’s SURE HOUSE, which won the 2015 Solar Decathlon hosted by the U.S. Department of Energy. SURE,
standing for Sustainable plus Resilient, represents the team’s vision for a post-Hurricane Sandy Jersey Shore home. The house uses 90 percent less energy than the average New Jersey home by implementing the passive house building standard.
SMA’s iconic line of Sunny Boy inverters has undergone a complete redesign of its popular models with Secure Power Supply. Ready to once again take over the North American residential PV market, the UL-listed Sunny Boy 5.0-US/6.0-US offers an increasingly robust feature set, allowing for reduced costs across all business operations and backed by the industry’s top-ranked service team.
Part 1: More Power
A lot more power. With the addition of the delta-grid compatible 30000TL-US, the Sunny Tripower TL-US line of three-phase commercial string inverters now packs even more punch than before. Since the dawn of commercial solar, no customer has ever complained about getting more power from the sun.
The Sunny Tripower TL-US series is adding a 30 kilowatt model to its line of proven three-phase string inverters. This latest cost-optimized solution continues to strengthen SMA’s commercial product portfolio. The Sunny Tripower 30000TL-US is an ideal choice for decentralized PV systems of all scales.
