The Maximum Power Point (MPP) of a photovoltaic module refers to the working state of the module when the output power reaches its peak under specific irradiance and temperature conditions. The core parameters include the maximum power point voltage (Vm) and current (Im), and the product of the two Read More

In the design or renovation of communication power supply and power distribution systems, we often encounter issues with cable selection and configuration. Recently, a seemingly simple but representative question has been repeatedly mentioned: "Can using two cables with a cross-sectional area of 120 Read More

Solar irradiance in photovoltaic power system refers to the amount of solar radiation power projected onto a unit area of surface per unit time, measured in watts per square meter (W/m ²). As a core indicator for measuring the strength of solar radiation, it directly determines the real-time output Read More

In China EV Charging stations will implement energy efficiency standards in November this year, and in the future, ev charging stations will also be labeled with energy efficiency levels like air conditioners.The below form shows the efficiency level of different grade.NAMEGrade 3Grade 2Grade 1effic Read More

In the power system where the proportion of renewable energy is increasing, energy storage technology has become the key to balancing supply and demand and ensuring grid stability. As the core equipment of the energy storage system, the Power Conversion System (PCS) acts as an efficient "translator" Read More

When photovoltaic inverters convert the direct current generated by photovoltaic modules into alternating current, they may contain direct current components and harmonics, three-phase current imbalance, output power uncertainty, etc. Currently, effective measures have not been taken to control them Read More

What's the solar inverter DC/AC ratio?It is the ratio of "total power of solar panels" to "rated output power of inverters", with the core function of "balancing power generation and equipment life", avoiding "big horses pulling small cars" or "small horses pulling big cars".For example, if your roo Read More

In telecommunication systems, lead-acid batteries are the core backup power source. Their core function is to provide continuous power supply to base stations and equipment in the computer room in the event of a power outage, avoiding communication interruptions. Its' backup time 'refers to how long Read More
