Science & Technology In October, Yamaichi Electronics w ill introduce its new Y-Sol3 T-Junction unit for the company’s connector product line. The T-Junction is designed to aid installers with module parallel connections. 64 The T-Junction is designed for a system voltage of up to 1,000 V, and a rated current of 30 A. It comes with precon- figured cables, with cross-sections of 6 Israeli company SolarEdge Technologies, with offices in Palo Alto, California, pulled back the curtain on its products at the Intersolar trade fair in Munich, Ger- many, six months ago. For the first time, SolarEdge presented its Smart DC ASIC technology, designed to open entirely new possibilities for PV system configuration. SolarEdge has since enhanced its product line with a 10 kW inverter. The complete system is consists of three components, the most important of which is the SolarEdge PowerBox; this unit replaces a module’s standard junction box, and optimally regulates the module’s power point. The unit maintains a uniform voltage for each module string, regardless of the number of modules connected in the string. The box can also deactivate any module auto- matically. This makes it safer to install the system, or in the event of a fire. Finally, this system has built-in theft protection, since no module can be removed without the system detecting it. The second component is the SolarEdge Inverter, which is available in 3.3 kW, 5 kW, and now 10 kW. The inverter doesn’t need an MPP tracker, since the PowerBox is responsible for this task. Using the pre- New Products at Solar Power 09 Yamaichi Electronics: Stand 2951 Japanese Company introduces T-Junction mm² and in different lengths. The non- locking connector is dust tight and pro- tected against immersion beyond 1 m (IP 68). The contact material is a tin-plated copper alloy. The connector can be used in ambient temperatures from -40 to 85 °C and is certified according to German norm DIN V VDE V 0126-3. Including the cable, each connector costs around $4.24 (EUR3) before taxes when ordered SolarEdge Technologies: Stand 2438 SolarEdge Technologies’s system includes the PowerBox, an inverter, and a monitoring portal. defined voltage values from the solar generator, the company’s inverter operates consistently and efficiently, regardless of the length of the individual module strings, or temperature. SolarEdge prom- ises efficiencies of more than 97 percent. All of this, the manufacturer argues, is possible due to the inverter’s very sim- ple, and therefore robust, construction New to Yamaichi’s Y-Sol range: the Y-Sol3 T-Junction. in quantities of more than 5,000 units. djs, mh www.yeu.com PowerBox to replace a module’s standard junction box – naturally, at the cost of an electronics unit in each module. The latter could be one of the most important counterarguments the industry may make against using SolarEdge. Still, the company is confident that its new development is completely reliable, and offers a 25-year guarantee for the PowerBox. The advantages of this system, the manufacturer says, aren’t limited to the module regulator and inverter. The third system component, a monitoring system called the SolarEdge Monitoring Server, benefits from the system’s over- all innovative configuration: after all, if the system can control each individual module, it can also capture opera- tional data from each module as well. The monitoring system can also capture data for strings, and the system as a whole. The new concept helps simplify system planning, since module strings of varying lengths pose no problem. It also facilitates the addition of modules to an existing generator. The company has not released pricing information. js www.solaredge.com November 2009
In September, Sustainable Energy Technologies Ltd. introduced a second-generation 5 kW inverter at the European Photovoltaic Solar Energy Conference in Germany. The Calgary-based company is now releasing two North America versions of its new inverter, the Sunergy ELV 208 and the Sunergy LV 208 – both designed as »extra low voltage power inverters.« The ELV has a maximum input voltage of 120 V, while the LV can manage as high as 150 V. Like the European models, Xandex Inc., a veteran of the semiconductor industry, launched a solar unit two years ago. At Solar Power 2009, Xandex Solar will announce its first PV product, the SunMizer DC power optimizer. Using a patent-pending technology called Optimum I-V for PV, Xandex says the SunMizer can efficiently recover power losses caused by shading and other system interference. According to Xandex, the SunMizer does this by ignoring a system’s proper- ly functioning modules. The units are only installed on those modules that generate less power than they should. According to a preliminary datasheet Sustainable Energy Technologies Ltd.: Stand 625 Extra low voltage power inverters these inverters have 95 percent peak con- version efficiency, and 94 percent CEC [SN1]efficiency. Both inverters also have modular designs. Each unit has a »transformer module« and a »power electronics module,« which facilitates cost-efficient mass production, and easy maintenance access. Together the transformer module and the inverter module weigh 78 kg. Sustainable Energy Technologies offers a 7-year standard warranty, and optional 10 and 20-year warranties. The company also Xandex Inc.: Stand 2252 Sustainable Energy Technolo- gies has released two new 5 kW inverters for the North American market: the Sunergy ELV 208, and the Sunergy LV 208 (pictured here).

Xandex says the product is also compat- ible with most 208 V and 240 V residential-sized inverters, and it conncects to modules with series wiring schemes. The 15 x 10 x 4 cm product will be available in the US early next year, fol- lowed by a release in Europe about three months later through a Xandex sub- Xandex Solar SunMizers can be installed selectively, that is only on modules that generate less than expected power. sidiary based in the Netherlands.
