The Influence Of Salt Spray And High Humidity Environments On Solar PV systems Updated On Tue, Sep 7th, 2021 by Saurenergy Background The working environment of a PV plant is relatively complex, and extreme environments such as high/low temperature, humidity, salt spray, heavy sand and other harsh environments, can test the reliability and environmental adaptability of the PV system. More and more PV plants are being built on water, desert, and in coastal areas. 2-3 years […] Read more
Extreme Events & O&M of Solar PV Plants Updated On Tue, Aug 24th, 2021 by Saurenergy Background Extreme weather events, driven by climate change, can have huge risks for solar PV systems too. For investors, reassurance of ongoing financial security of their solar system is critical to securing initial investment. PV plants are installed outdoors and whilst generating electricity, they also endure the test of nature and all her elements. How […] Read more
PV Plant Safety. Inverter Power On and Power Off Operation Updated On Sat, Aug 7th, 2021 by Saurenergy Background During the operation and maintenance of a solar PV plant, we often power off and power on the inverter, which is normally related to the safety of equipment and the personal safety of O&M personnel but is there anything specific we should look out for during what is seemingly a very simple process? In […] Read more
Solis Seminar, Episode 27 : How does a single-phase inverter connect to split-phase grid Updated On Mon, Aug 2nd, 2021 by Saurenergy Background In some special countries and regions, the grid structure involves split-phase grid, but if there is no split-phase inverter when installing PV system, can the conventional single-phase inverter be connected to the grid? What problems should we pay attention to? We will share them with you in this Solis seminar. About 120V/240V Split Phase […] Read more
Frequently Asked Questions about the Export Power Manager (EPM) Solution Updated On Fri, Jul 9th, 2021 by Saurenergy The Solis EPM accessory, as an energy control device, has an enormously powerful function. In addition to controlling the energy output of the PV system, it can also be used as a reactive power adjustment and power factor compensation device. During installation we hear common questions being asked so in this episode of Solis Seminar we’ve collated the most […] Read more
Solis Seminar : Solution to “OV-G-V0X” alarm Updated On Tue, Jun 29th, 2021 by Saurenergy Background In PV systems, grid over-voltage faults (OV-G-V0X) can occur frequently, especially in areas with weak grids and high solar PV grid-connected capacity. Such faults are common and in this episode of Solis seminar, we will share with you the causes of “OV-G-V0X”, and how to rectify the issue. Fault Description During normal operation of […] Read more
Solis Seminar, Episode 24: PV Panel Micro-Crack Problems and Identification Methods Updated On Fri, Jun 18th, 2021 by Saurenergy The last Solis Seminar introduced the problem of PID effect and its solutions. This seminar will give details on the causes of cell micro-cracks, how to identify them and ultimately prevent them. PID effect, micro-cracks, and hot spots are three important factors that can affect the performance of crystalline silicon photovoltaic modules. Among them, PID […] Read more
Solis Seminar- Solution For PID Recovery Updated On Fri, Jun 11th, 2021 by Saurenergy Potential Induced Degradation (PID) is a phenomenon which affects some PV modules with crystalline Si cells and leads to gradual deterioration of performance. The degradation can be as much as 30% or more after a few years. Some module manufacturers are already working to develop countermeasures by using new materials, but the general trend to […] Read more
Solis Seminar Episode 21: Installing AC Circuit Breakers Correctly Updated On Wed, May 19th, 2021 by Saurenergy Background Recently, a customer reported that the circuit breaker in the fuse box of the newly installed solar PV system was experiencing an abnormal arc when it was disconnected. The customer suspected that it was caused by the inverter, however, a Solis technical engineer discovered that the circuit breakers were reversed fed. After replacing the […] Read more
