Correct Use of Aluminum Core Cables in PV Systems Updated On Mon, Oct 4th, 2021 by Saurenergy Grid transmission cables are usually aluminum core. Therefore, in the construction of PV plant projects in residential and commercial areas (especially household PV plant), many users will use aluminum core cables to directly interface with inverter output ports or circuit breakers ports. This can cause many safety problems. This Solis seminar will share the correct […] Read more
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
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
Saving Your Rooftop PV Plant From a Lighting Strike Updated On Sat, Jan 9th, 2021 by Saurenergy Background Residential PV systems are generally installed on the rooftop of residential buildings, with a large metal surface area, higher distance from the ground and exposed location. That makes these PV systems a possible target for lightning during thunderstorms. Thus, having good lightning protection and grounding becomes key to avoid any incidents that could cause […] Read more
Common O&M Problems With Inverters In the Winter Time Updated On Thu, Feb 23rd, 2023 by Saurenergy Background Solar plants, if planned and maintained well, can comfortably withstand winters too. With winter comes cold temperature and sometimes extreme weather, such as snow, freezing rain, or even polar freezes. In low temperatures, you need to pay more close attention to your inverter’s operation and maintenance (O&M). This episode from Solis’ seminar series, we […] Read more
What To Do When Your Inverter Gives “G-PHASE” Alarm Updated On Fri, Oct 29th, 2021 by Saurenergy Background In PV systems, there can be errors caused by problems on the grid side. As an important operating function of a solar PV system and the grid, inverters are very sensitive to grid problems and will respond quickly. Among them, grid imbalance faults, although rare, can easily affect inverters, PV systems and sometimes even […] Read more
Commercial & Industrial PV Adopts 1500V High-Power Solutions. What Do the Cost Savings Look Like? Updated On Fri, Dec 4th, 2020 by Saurenergy For a long time, distributed solar pv plants have been an important part of the clean energy mix. Most solar projects are 1100V and 1000V, but with the adjustment of policies across the globe, grid parity, cost reduction and efficiency increase have become the primary considerations of developers of distributed power stations. Under this new […] Read more
