With the Sunny Boy 240<\/a>, SMA offers now a micro inverter as well. However, to take full advantage of a module concept, it was produced by doing more than simply scaling down the usual string inverter.<\/p>\n

<\/p>\n

 <\/p>\n

Micro inverters, or very small inverters for individual PV modules, have been on the market for a number of years now and their impact is increasing significantly, thanks to the special advantages only they can offer. They make system planning extremely simple, ensuring easy plug-and-play installation, preconfigured series connection (daisy chain) and\u00a0 efficient system operation, along with yield monitoring for each individual PV module and straightforward expansion options, even with different module types. A micro inverter system is also ideal for challenging applications with partial shading, complex roof structures, different roof orientations or small-scale systems. Unlike systems with string inverters, micro inverter systems can be expanded modularly with Sunny Boy 240 at any time, as needed and depending on the financial resources available.<\/p>\n

\"Modularity<\/a>

Modularity in series: Up to 12 Sunny Boy 240 devices can be daisy-chained with the Sunny Multigate.<\/p><\/div>\n

Micro inverter as a technical challenge<\/h5>\n

Why has it taken until the beginning of 2014 for SMA to produce a micro inverter? Because a \u201cquick and dirty\u201d version wouldn\u2019t actually make any sense. Along with their aforementioned advantages, micro inverters also must face up to a few inherent challenges. Inverters are technically advanced devices made of many electronic components. Their high quality is due to many years of operational experience, development and countless tests. In principle, this also applies to micro inverters, but here probability can throw a monkey wrench into the works.<\/p>\n

 <\/p>\n

 <\/p>\n

If you install micro inverters in a 5-kWp PV system, you suddenly find that, instead of one inverter, around 20 are in operation \u2013 one for each module. Theoretically, the likelihood of error also increases with the number of components. However, micro inverters easily compensate for this. First, they guarantee much higher reliability per device compared to string inverters \u2013 in particular by reducing the number of components and with their meticulous design. Second, if a single micro inverter has a possible malfunction, yield loss is kept within narrow limits (in the mentioned example one twenties of power is missing, in the worst case).<\/p>\n

 <\/p>\n

Fifty percent fewer components<\/h5>\n

Ultimately, we have developed an inverter with a mere 176 high-quality components \u2013 fewer than the current competitor products offer. At 19 cm wide, 22 cm long and 4.4 cm high, the micro inverter\u2019s enclosure is just about the size of a chocolate box. Additionally, there are absolutely no screw joints needed to assemble the device. The small inverter generates 230 W of power and therefore is the perfect match to the powerful PV modules of the latest generation. Thus, a single highly integrated, analog circuit controls the inverter bridge, replacing several analog-digital converters and control computers, along with their infrastructure. As standard, the Sunny Boy 240 baseplate has several mounting options and, no matter where the device is mounted, there are no additional big components needed. Installation and connection are also extremely easy thanks to the ready-made, easily identifiable plugs.<\/p>\n

Red Dot Design Award; Category: Product Design<\/p><\/div>\n

<\/h5>\n
Recognition of excellence<\/h5>\n

We won the well-respected\u00a0reddot design award for the Sunny Boy 240<\/a> system and came out on top over 4,500 professional competitors. According to the judges, the product\u2019s most impressive features are its design, compact size, great mounting flexibility and independence from any additional components.<\/p>\n
