  • How to select solar panels for your RV off grid system

    How to select solar panels for your RV off grid system

    Mar , 09 2022
    When it comes to actually collecting energy from the sun, that’s where solar panels come in. There are a few different solar panel options available to choose from. Mono-crystalline vs. Polycrystalline Panels Choosing between mono-crystalline and polycrystalline panels is one of the first steps to take when shopping for solar panels. Polycrystalline panels are light blue in color, and they are les...

  • Efficiency of DC power system

    Efficiency of DC power system

    Jun , 27 2022
    In this article we will explain the efficiency of DC systems and progress to AC systems on the next article. In very basic terms, efficiency is the measure of how much power is not being wasted by a system. More waste is less efficient. In electrical systems, we measure the power entering a system in watts; the unit of measure for work performed. Efficiency is the ratio of (Power-In) -vs. - (Power...

  • Theoretical introduction to an AC power system

    Theoretical introduction to an AC power system

    Jul , 22 2022
    AC Power Systems have plenty more units, terms, measurements, interesting waveforms and math to describe their behavior. Any formulas presented here are for reference and validation only. The intension of this paperis convey the concept without having to seriously crunch numbers. All the terms and formulas interweave so itis difficult to create a flow of one topic to another without skipping aroun...

  • What are the soft costs of datacenter?

    What are the soft costs of datacenter?

    Jul , 22 2022
    Data centers can’t afford to go dark. That’s why reliable critical power systems arecentral to their operation. Selecting and maintaining these systems comes at a price, but astronger understanding of “hard” and “soft” costs -- and what can be done to mitigate thelatter -- can protect the bottom line. Hard and soft costs vary from one operation to the next. In general, hard costs refer to the expe...

    How to lower the soft cost of Data center

    Aug , 01 2022
    Outages are a major fear for data centers. And for a good reason. Unfortunately, many companies still roll the dice by purchasing critical power systems,assigning someone internally to keep tabs on the equipment, and simply hoping the system comes through when it needs to. (Spoiler: it often doesn’t.) Scarce resources, a lack of skilled personnel, and increased edge computing (and the scattered fa...

  • Solar battery life time

    Solar battery life time

    Aug , 08 2022
    There are two ways to answer this question and the first is to determine how long a solar battery can power your home. In many cases, a fully charged battery can run your home overnight when your solar panels are not producing energy. To make a more exact calculation, you’ll need to know a few variables, including how much energy your household consumes in a given day, what the capacity and power ...

  • Power Factor and Harmonic Analysis in Single phase AC to DC converter

    Power Factor and Harmonic Analysis in Single phase AC to DC converter

    Aug , 15 2022
    Most of the power conversion applications consist of an AC to DC conversion stage and this DC output is then used for further stages. An AC to DC converter is an integral part ofmost of the electronic equipment as most of these equipment are DC powered [1]. Generally to convert AC toDC a diode bridge rectifier is used. To reduce the ripple in the output voltage a suitable filter capacitor is used ...

  • Influence of SEI film on the performance of Li-ion battery

    Influence of SEI film on the performance of Li-ion battery

    Sep , 05 2022
    After extensive research, it has been found that the properties of SEI films greatly affect the performance of Li-ion batteries. During the formation process, the amount of the SEI film formed represents the amount of lithium in the consumed lithium-ion battery, which directly determines the capacity of the lithium- ion battery. Therefore, in the process of forming the SEI film, the less lithium i...

    How a UPS system works with a Generator

    Sep , 19 2022
    As weather extremes and storms increase, power outages are likely to continue to rise. According to the U.S. Energy Information Administration, U.S. customers experienced an average of nearly six hours of power interruptions in 2018. If you have invested in a generator, you’ve prepared for when a storm hits, right? Almost. Even with a generator, you still need a battery backup, also known as an Un...
