Grid injection inverter

    Grid Injection Inverter

    With zero injection photovoltaic inverters, the energy from the solar modules is injected directly into your home's electrical grid. By simply connecting the solar inverter to your home's electrical system, you will see a surprising reduction in your energy consumption. Our zero injection inverters have a built-in SMART METER function to avoid discharges into the contracted electrical grid. The usual consumption of a home's appliances is permanent, so it will benefit from the solar energy that is produced by the solar panels throughout the day, only having to use the contracted electrical network at night. They are all advantages at an unbeatable price.

    What are Grid Connection Inverters like?

    Grid-connected solar inverters are basic devices in renewable energy installations, since their function lies in changing the direct current input voltage to a symmetrical alternating current output voltage, with the magnitude and frequency desired by the user or designer. That is, it is what will make it possible for us to convert the energy we acquire from the sun, water, air, etc. in electrical energy adequate for our purposes. Its general classification is made into two types: single-phase inverters and three-phase inverters.

    With this grid connection system we do not have elements such as batteries, which allow us to store energy to consume it when it suits us, but rather it must be consumed instantly: it only operates from sunrise to sunset. That is why among the most prominent and beneficial uses of this type of grid-connected inverters is the energy supply of large areas, such as large solar farms. In this category single-phase inverter and three-phase inverter.

    Self-consumption investors

    An on-grid inverter (also known as a grid-tied inverter) is a type of inverter used in solar photovoltaic energy systems that are connected to the electrical grid. These inverters convert the direct current (DC) generated by solar panels into alternating current (AC) that can be used in the home or sent to the electrical grid.

    On-grid inverters are different from off-grid inverters, which are designed for off-grid solar power systems and typically include batteries to store energy. On-grid inverters do not have batteries and are designed to synchronize with the electrical grid and adjust solar energy production accordingly.

    When a solar energy system produces more energy than is currently being used, the excess energy is sent to the electrical grid through the on-grid inverter. If the solar energy system is not producing enough power at a given time, the on-grid inverter can draw power from the electrical grid to meet the home's energy needs.

    On-grid inverters can also include advanced features such as remote monitoring, maximum power point tracking, and zero injection technology, which limits the amount of power sent to the grid to prevent overloads.

    In summary, on-grid inverters are used in grid-connected photovoltaic solar energy systems and allow the conversion of direct current (DC) to alternating current (AC) to power homes and send excess energy to the grid. electrical.

    What is a 0 discharge equipment?

    An anti-energy discharge device is a piece of equipment that is responsible for constantly measuring the energy consumed by the home to avoid injecting excess energy from the panels into the network. The discharge device 0 takes a reading of the energy consumed at each moment in the home, and communicates it through a data cable to the connection inverter, which will be responsible for modifying the working point of the panel to produce only the that is consumed, and thus avoid the injection of surpluses into the network. That is, in compliance with Spanish regulations, 0 discharge devices avoid discharging into the network the energy produced by the photovoltaic panels and not consumed.

    Depending on the grid connection inverter, a 0 discharge device or another will be compatible, thus, for example with a grid connection PlusEnergy inverter is compatible with the PlusEnergy Sun-1000w-2000w, as well as with the PlusEnergy Sun-3kw to 6kw or either with the PlusEnergy Sun- 8kw to 80kw and depending on the needs of the installation, one model or another will be convenient.​
