TSUN

TSUN , a professional provider of energy storage solutions, has announced the launch of PV Rapid Shutdown Solution , which is a simple and economical Rapid Shutdown Solution that meets the requirements of the US NEC2017 690.12 standard. Adding the Rapid Shutdown Control Unit to the original PV system, when the PV module has a safety hazard, shutting the system down only needs one button. It can quickly turn off the corresponding PV modules within seconds, highly improves the safety of rescue, and reduces the loss of the PV system when it encounters a fire risk. In the PV system, PV panels are connected in series, so the voltage of the whole line is accumulated and can easily reach to a high voltage of 600V-1000V. When fire occurs, as long as there is sunlight on the DC side, the panel will keep on generating power. But when the DC side is with a high voltage of 600V-1000V or even above, the firefighters will not be able to put out the fire taking direct risk of electric shock. Therefor...

Growing solar photovoltaic demand In the past 2019, global solar photovoltaic installed capacity has also grown tremendously. Taking the European Union as an example, according to data from Solar Power Europe, 2019 is the best year for solar photovoltaic development in the European Union, with 16.7 GW of new installations, an increase of 104% (8.2 GW of new installations in 2018). Spain increased its installed capacity by 4.7 GW in 2019, making it the EU’s largest solar market, followed by Germany (+4 GW), the Netherlands (+2.5 GW), France (+1.1 GW) and a surprised Poland (the installed capacity quadrupled in 2019, reaching 784 MW by the end of 2019, and the EU’s incremental photovoltaic capacity reached 131.9 GW, an increase of 14% from last year (the total installed capacity at the end of 2018 was 115.2 GW). As it continues to rise, some security risks are gradually emerging. Increasing concerns for the safety of photovoltaic systems For photovoltaic systems, there are two major...
