Solis Seminar: Online O&M Dispersion Analysis Updated On Wed, Sep 6th, 2023 by Saurenergy Background PV plants are an incredible asset with long-term income. Their construction is quick, but the time required for operation and maintenance is more than 25 years. Compared with small PV plants, the number and scale of large PV plant components are very big, and late O&M and troubleshooting is increasingly difficult. There can also […] Read more
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
