New productsGe’s latest central invertertechnology clears path forutilities to boost solar energyproduction worldwideMarking a new technology milestone inthe global effort to increase renewableenergy production by driving down overallsystem costs, GE has deployed the first1,500-VDC (volts, DC current) open circuit(OC) central inverter for utility scalesolar power plants. The inverter will helpreduce overall system costs, which is vitalto making solar power a more economicalalternative to fossil fuel technologies.Central inverters are key componentsof photovoltaic (PV) plants. The technologyconverts DC power produced by solarpanels to AC power, which is then fed intothe main grid.GE Energy’s Power Conversion businessdeveloped, built and delivered its1,500-VDC ProSolar central inverter technologyto solar power plant system integratorBELECTRIC, the global market leaderin terms of installed power. BELECTRICinstalled GE’s advanced central inverterat its new solar power plant in southernGermany, utilizing PADCON’s 1500 VDCSystem Technology.The 1,500-VDC OC central inverterfor BELECTRIC is designed as an outdoorversion and offers a number of key benefits.Most notably, it allows operation at highDC voltages on panel level with lower DCcurrents while increasing the rated powerfor inverters. This can result in significantlylower costs for the technical DC infrastructureas well as the overall balance of systemcosts. Since the power of the invertersystem is limited mainly by the current,the power can be substantially increased byincreasing the operating voltage, and thismeans additional cost savings.Due to higher operating DC voltageand higher output with the same size asconventional ProSolar 1,000-VDC OCinverter units, the 1,500-VDC OC solutionoffers higher power density with thesame small footprint that means optimizedand flexible site layout. The liquid-cooledand improved power electronic topologyensures high efficiency, especially in partialload operations and is developed in Berlin.www.ge.combalqon introduces hIQaPlithium battery for solarenergy storage applicationsBalqon Corporation introduced low costhigh capacity lithium batteries as an alternativeto the current industrial deep cyclelead acid batteries. The new HIQAP batteriesare available in 12, 24 and 48 Voltconfigurations with an amp hour capacityranging between 700 Ah to 1000 Ah.HIQAP battery packs include Balqonproprietary Battery Management System(BMS) and related power electronics componentsfor direct replacement of currentlead acid battery packs. HIQAP lithiumbattery packs are designed to support largedaily loads requiring deep depth of dischargeand high energy transfer efficiencyfor solar, micro-grids, off-grid storage andtelecom applications.“With estimated life of over 10 yearsand high energy transfer efficiency oflithium batteries, users can now capture15 percent more energy from the solarpanels,” said Balwinder Samra, CEO ofBalqon Corporation.HIQAP batteries include large format1000 Ah and 700 Ah, 3.25 VDC foldedprismatic cells connected in a series, availablein 12V, 24V and 48V configurations.Life cycles of HIQAP(TM) batteries varyfrom 2500 cycles to 5000 cycles based ondepth of discharge. Low internal resistanceallows for over 95 percent efficiency duringenergy transfer compared to 80 percentefficiency of equivalent deep cycle lead acidbatteries. www.balqon.comTMeIc’s Solar ware® MainSite controller providescentralized management ofutility-scale PV installationsBuilt on decades of engineering experiencewith power electronics, the Solar Ware®Main Site Controller (MSC) from TMEICoffers the industry’s most advanced gridmanagement. The MSC provides overallcoordination and control of the PV plantby providing access to complete informationregarding the plant’s power production,as well as single point access to thestatus of all inverters. The MSC also operatesmultiple Solar Ware® inverters.A typical Solar Ware® installationconsists of multiple Solar Ware® stations,configured with multiple power channels.The power channels include PowerOptimization and a DC box. The MSCcontinually monitors all the solar invertersat the site and adjusts commands in orderto accomplish site-wide power qualitygoals. www.tmeic.comcentrosolar online tool nowalso available internationallyThe German solar company Centrosolarlaunched an English-language version ofthe Centrocheck planning tool to the internationalmarket. Centrocheck helps installersplan solar installations in any country.It complements the already established toolfor clients in North America where installersuse a special online portal customizedfor that market with unique designand financing capabilities. Each countryversion automatically includes the solarpanels, inverters and the country-specificcalculation basis available for use in eachparticular country.Centrocheck is the only planningsystem that comprehensively covers projectdesign. The intuitive tool providesall the information necessary to plan,build and operate a photovoltaic system.Centrocheck can be used online underwww.centrocheck.com without havingto be installed on the user’s computer.Centrocheck is also available as an app –fully independent of the operating systemon the mobile end device. Users can usetheir smartphone to access the programservices on the go and free of charge underwww.m.centrocheck.com. The programuses integrated functionality to recognisethe position and inclination of the roof, aswell as on-site irradiation data. www.centrocheck.comSolar Maid introduces newo&M cost reduction toolSolar Maid’s new solar O&M cost reductiontool, Soil Boundary Analysis, helpssolar system owners and managers betterdetermine optimal O&M scheduling, for adirect cost savings.
