Philippines: World’s Largest Photovoltaic Plant Including String Inverters Commissioned


The Catalagan Solar Farm on the Philippine island of Luzon was commissioned in March. At 63 MW, it is the world’s largest photovoltaic plant including string inverters, supplying solar power to the entire western part of the Batangas province. Spread over approximately 160 hectares (about 400 acres), the solar farm includes more than 200,000 PV modules, along with 830 Sunny Tripower 60 inverters and 23 SMA Inverter Managers.

How a regional SMA training center is imparting PV knowledge in East Africa


Small- and medium-sized grid-tied renewable energy systems have recently created interesting investment opportunities in Kenya. Electricity tariffs ranged from 0.14 US$/kWh for large industrial consumers to 0.226 US$/kWh for normal household consumers in December 2014. As the market segment solar PV grows, the main question for both utility companies and investors is the possibilities of reducing cost of power production and its maintenance.

5 Reasons to Visit SMA at Intersolar


Internationally, everyone is wrestling with implementing the Paris climate agreement; and in Germany the next reform of the Renewable Energy Sources Act (EEG) is looming—both indicators that, the (global) energy transition is still an important issue and that solar energy is an important factor to success. To that end, this year at the industry get-together, Intersolar Europe in Munich, we’ll be presenting system solutions to help every type of user generate and store energy and cut energy costs. Curious? Then come and have a look at our booth.

Service Tip: Changing the inverter’s network setting using SMA Connection Assist


When it’s not possible to locate an SMA inverter using Sunny Explorer or other SMA communication devices, SMA CONNECTION ASSIST is the perfect tool to use. SMA Connection Assist can be used to change the inverter’s network setting using Speedwire connection. As every installation site has its own level of network security, many high-level network securities require a static IP address setup so that the IP address of the inverter doesn’t come into conflict with the IP address of the devices used by the client on a daily basis.

Gamechanger: Storage systems are revolutionizing the energy landscape


Renewable energies produce electricity when the sun is shining or the wind is blowing. But people need electricity whatever the weather, 24 hours a day. Is this an unsolvable problem? No, not at all. Because battery technologies are rapidly making progress. This is enabling more and more people and companies to save surplus electricity and use it later on – supplying themselves with solar power more or less independently. Exciting times for Sam Wilkinson, who heads the energy storage team at analysis company IHS, and Dr. Aleksandra-Sasa Bukvić-Schäfer, a storage system expert at SMA.

Tech Tip: Complying with Earth Fault Alarm (Australia)

Anwar Mahmood, Service Engineer from SMA Australia, explains the different options available for complying with Earth Fault Alarm according to Australian standards. According to Clause 3.4.3 of AS/NZS 5033, PV systems installed after 11th July 2015 which have an array operating at Low Voltage (that being greater than 120V DC) must include earth fault alarm capability. For SMA inverters, there are three options which comply with these standards. Anwar explains these options in this Tech Tip video.
