The original test report for the Growatt 5000MTL was published in PHOTON International this summer (see PI 7/2012, p. 98). Aft er a few initial problems due to a defect, this transformerless, single-phase device with a nominal DC capacity of 5.2 kW delivered a perfectly acceptable performance. Its PHOTON effi ciency of...
Our goal: Helping system operators select the right inverters. Since the beginning of 2007, we at PHOTON Lab have employed our own inverter test methodology. In agreement with our test partners, the test results are regularly published in PHOTON magazines. To make these results easier to comprehend, the editorial staff, drawing its inspiration from...
Despite a few &aws, the 5000TL from China’s Growatt New Energy can hold its own against many European devices Just last month, we published the results of PHOTON Laboratory’s tests of a promising new inverter from Chinese manufacturer Sungrow – the SG4KTL (see PI 1/2011, p. 118). But that device is already...
A 20 kW device made by Growatt, the 20000TL3-HE, is only the second inverter tested by PHOTON Lab to achieve a conversion efficiency higher than 99 percent. The device scores third place overall, even without silicon carbide transistors When combing through the PHOTON database for all inverters currently available on the market...
