  • Classification of inverters based on wave type (Pure Sine wave)

    Classification of inverters based on wave type (Pure Sine wave)

    Aug , 29 2022
    Power inverters can be mainly divided into pure sine wave inverters and modified sine wave inverters according to their waveforms. In fact, there is another type - square wave inverter, the earliest inverter, which is rarely seen now. Pure sine wave inverter The pure sine wave inverter outputs true sine wave alternating current without electromagnetic pollution, which is the same or even better th...

  • Major Interconnection Issues for Energy storage solution

    Major Interconnection Issues for Energy storage solution

    Oct , 31 2022
    Major Interconnection Issues Generally, DG-based power systems can operate in independent or stand-alone and grid-connected modes. In fact, in the first mode, the capacity of a DG unit is selected only based on the load requirements. But, in the latter case, this constraint is not determinant. Although the grid-connected operation mode usually is preferred due to the bilateral energy exchanges, th...

  • Why battery energy storage moving to higher DC voltages (Part-1)

    Why battery energy storage moving to higher DC voltages (Part-1)

    Nov , 08 2022
    Today, most utility-scale solar inverters and converters use 1500 VDC input from the solar panels. Matching the energy storage DC voltage with that of the PV eliminates the need to convert battery voltage, resulting in greater space efficiency and avoided equipment costs. The evolution of battery energy storage systems (BESS) is now pushing higher DC voltages in utility scale applications. The Woo...

    Why Solar and storage are key to reducing geopolitical risk and securing access to energy?

    Nov , 08 2022
    Energy prices have surged sharply this year due to seeral factors, including the release of pent-up demand post-COVID and supply disruption due to the Russian invasion of Ukraine. The sudden increase in energy prices and its contribution to rising inflation is causing policy distress globally as consumers face soaring costs of living. In the UK, for example, households are experiencing a “cos...

    Advantages of combining solar and energy storage

    Nov , 08 2022
    Grid stability, battery safety and blackout prevention Solar-storage solutions can act as sunshine insurance, allowing stored power to be dispensed when power demand is high (and accompanied by higher prices) and solar generation is low. Aided by these smart technologies, unified solar and storage can also help prevent blackouts, an issue seen from Australia to California, Lebanon to South Africa....

  • Barriers to widespread adoption of solar-plus-storage

    Barriers to widespread adoption of solar-plus-storage

    Nov , 08 2022
    The main barrier to widespread adoption of solar-plus-storage is know-how: configuring the optimal design, gauging investment, and navigating risk management (including regulations), and the high complexity and cost of managing these systems. In configuring the optimal system design, one faces challenges such as designing the ideal battery configuration to maximise return on investment (ROI), figu...

  • What is the basic operation of inverter?

    What is the basic operation of inverter?

    Nov , 14 2022
    What is an Inverter? An inverter converts the DC voltage to an AC voltage. In most cases, the input DC voltage is usually lower while the output AC is equal to the grid supply voltage of either 120 volts, or 240 Volts depending on the country. The inverter may be built as standalone equipment for applications such as solar power, or to work as a backup power supply from batteries which are charged...

  • Should I get battery storage for my solar energy system?

    Should I get battery storage for my solar energy system?

    Nov , 28 2022
    Imagine you’re home on a stormy night, watching TV with the washing machine running, and all of a sudden the power goes out. Now imagine the same scenario, except you have a rooftop solar energy system with battery storage. When the power goes out in your neighborhood, you’d be blissfully unaware.   A common myth about solar power is that you can count on it only when the sun is shining. You ...

    7 tips for optimizing design of zero net energy buildings

    Dec , 19 2022
    In an increasingly environmentally conscious society, Zero Net Energy (ZNE) buildings has risen in popularity taking green building design and construction to new heights. The ZNE space has increased 700% since 2022 .Clearly ZNE is not a fad. ZNE is solving a real problem to help the environment. So are you thinking of pursuing net zero? If so, here are some tips to consider. Plan for grid optimiz...

    Preparation of lead-reduced graphene oxide nanocomposites and their applications

    Jun , 14 2023
    The shortcomings of lead-acid batteries are: low energy density and short cycle life. Lead sulfate formed by the negative plate of the lead-acid battery during the discharge process, after the battery is placed, the small particles of lead sulfate will be converted into large particles of lead sulfate, and the large particles of lead sulfate will not be converted into lead during the charging proc...

  • Comparison of N-type and P-type cells for photovoltaic modules

    Comparison of N-type and P-type cells for photovoltaic modules

    Aug , 18 2023
    Photovoltaic cells are classified by substrate material and can be divided into P- and N-type batteries. A P-type battery refers to a battery with a P-type silicon wafer as the substrate, and an N-type battery refers to a battery with an N-type silicon wafer as the substrate. P-type silicon wafers have a simple production process and low cost, while N-type silicon wafers usually have a long life a...
