Kstar launches 1,500 V string inverter
The transformer-free 250 kW product offers a reported efficiency of 99%, providing a European rating of 98.5%.
SolarEdge violated Huawei inverter patent, rules Chinese court
Huawei said the Guangzhou Intellectual Property Court in China has ruled in its favor in a patent dispute with its Israeli rival.
Chinese PV Industry Brief: Polysilicon, module prices continue to rise
Polysilicon prices continued to soar this week. Prices have been rising across the PV supply chain since mid-July due to recent accidents at two Chinese polysilicon factories, according to EnergyTrend.
Covid-19 weekly round-up: Updates shed light on tough second quarter for solar industry firms
But Israeli inverter company Solaredge and Indian engineering, procurement and construction services provider Sterling and Wilson have both offered hope of a recovery in Europe as Chinese glass producer Xinyi said it kept the furnaces going throughout the worst of the pandemic.
Enphase Q2 micro-inverter revenue falls despite demand ‘rebound’
Coming off a strong, profitable first quarter, Enphase sees the second-quarter results of Covid-19 in compressed revenue and a swing to a loss. Gross margins remain strong.
SolarEdge up 12% after hours on second-quarter revenue and solid earnings – despite Covid-19
The inverter and energy storage company was able to maintain its streak of profitable quarters in what was expected to be a hard period for solar and the Israeli business said it sees “signs of recovery in the U.S.”
Finnish industrial park gets 12 MW smart grid with central inverters
Inverter manufacturer Fimer provided its PVS980-58 central inverter solution for the project, which will derive 35% of its energy from solar PV.
Strategies to prevent overvoltage-induced inverter disconnections
Australian scientists have identified seven methods to prevent PV losses when overvoltage-induced inverter disconnections occur. The methods include battery storage, reactive power inverters, export limits, distribution static synchronous compensators, the replacement of old conductors in power grids, load reconfiguration, and dynamic voltage restoration.
Fuzzy logic MPPT to improve PV system performance
A Pakistani-Chinese research group has demonstrated a new maximum power point tracking method, based on a fuzzy logic algorithm to provide faster results. The converter tech is claimed to have an impact on PV system efficiency and provide isolation between the load and the PV array.
Temperature-based MPPT algorithm to improve PV system efficiency
Researchers in Spain have developed a maximum power point tracking (MPPT) algorithm based on just one input parameter – PV module temperature. The algorithm has already shown stability in testing, the scientists claim.
