Solis Seminar: Inverter Starts up Late? Find Causes, Troubleshoot Problem Updated On Mon, Oct 17th, 2022 by Saurenergy The amount of power generated by a solar power system is positively correlated with the grid-connected working time of the system. Under the same conditions, the earlier the inverter starts up and connects to the grid, the higher the power generation. For example, in the same summer, one inverter can usually start up and be […] Read more
Solis Seminar On The Importance of Using Photovoltaic Cables in Photovoltaic Systems Updated On Tue, Jun 28th, 2022 by Saurenergy Background In some photovoltaic power plant projects, ordinary cables have been used in replacement of dedicated photovoltaic cables, which can provide lower installation costs. This approach puts the entire solar PV system at risk and is dangerous. In this Solis seminar we introduce the differences between photovoltaic cables and ordinary cables, and the importance of […] Read more
Solis Seminar Episode 38: Installation Tips to Prevent Inverter Soaking Updated On Tue, Jan 4th, 2022 by Saurenergy Background During the process of on-site investigation, you can encounter the problem of inverter failure caused by water ingress. Sometimes there is still water ingress after replacing the new machine and this requires investigation to understand the cause of water ingress from the installation. Troubleshooting Guidance The protection level of the inverter is IP65 or […] 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
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 22: Solutions for Error Code “GRID INTF” Updated On Thu, May 27th, 2021 by Saurenergy The power grid is a fragile and complex system and its operation will affect connected equipment. At the same time, the abnormal operation of connected equipment will also affect it causing what’s known as, “grid disturbance”. Grid disturbance is a relatively common type of a grid-side fault. The frequency of its occurrence is second only […] 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
