  • Developing an Energy Management Strategy (EMS) for LiFePO4 based ESS

    Developing an Energy Management Strategy (EMS) for LiFePO4 based ESS

    Aug , 31 2021
    Working closely to setup large-scale Lithium battery based Energy Storage System (ESS) for a wide variety of main grid, weak grid and micro grid installations; EverExceed has significant experience and insight on the real-world operation and optimization of energy storage technology. The most important consideration for any ESS is to view it as part of a whole system rather than as a sta...

  • Why, when and how to clean solar panels?

    Why, when and how to clean solar panels?

    Aug , 31 2021
    A car that’s well-oiled and serviced runs better, so there’s no surprise that solar panels do their job more efficiently when they’re given the same level of attention. Your new solar system requires very little maintenance, but a clean solar panel is much more efficient than a dirty or dusty one. Your solar power system’s output may be reduced if your panels are covered in dust, dirt or grime. Th...

    Evolution of different solar cells_M2 cells

    Aug , 31 2021
    The first modules had a power class of 48 watts in 1983. Here 36 cells with the dimensions 100 x 100 mm were used. The first modules had a power class of 48 watts in 1983. Here 36 cells with the dimensions 100 x 100 mm were used. This cell size was available on the market until about 1996. The first IBC Megaline modules with 120 watt, manufactured in the USA, were based on the dimensions 125 x 125...

  • Tips for troubleshooting when your off-grid system doesn't work

    Tips for troubleshooting when your off-grid system doesn't work

    Sep , 01 2021
    Usually off-grid system used to get 24/7 uninterrupted power supply and also to minimize CAPEX to the lowest. So, when an off-grid system goes down, it's really hard and it becomes harder if you're an amateur  on solar system. Considering this hardship for the new comers or amateur on solar system, our technical team has noted down some important troubleshooting tips which can help to get the...

  • Generator vs Solar Energy System- Which one to choose?

    Generator vs Solar Energy System- Which one to choose?

    Sep , 01 2021
    A well-designed solar system can meet the majority of the electricity needs for a homeowner, but there are times when power needs to be pulled from the grid. While many energy providers give the option of net metering to cover the cost of electricity used from the local power company, it’s not available to all solar homeowners. Having a backup supply of electricity can provide power during outages...

  • What factors are affecting the side reactions of lithium deposition?

    What factors are affecting the side reactions of lithium deposition?

    Sep , 17 2021
    When charging lithium ion battery, Lithium precipitation not only reduces the performance of the battery and greatly shortens the cycle life, but also limits the fast charging capacity of the battery, and may cause disastrous consequences such as combustion and explosion. In a series of articles we will discuss about the problems from the macro scale of lithium-ion battery, working conditions, gra...

    Lithium battery failure model-explain the phenomenon of lithium evolution in graphite anode: part-1

    Nov , 01 2021
    During the long-cycle cycle, the reversible capacity of the lithium-ion battery will continue to decrease due to the reduction of active materials, the precipitation of metal lithium, the continuous consumption of electrolyte, the increase of internal resistance and thermal runaway. Among them, the lithium evolution phenomenon of the graphite negative electrode is the most important cause of batte...
