A properly selected inverter, also called an inverter, will guarantee the long-term and efficient operation of a photovoltaic installation. First of all, it must be reliable, safe, equipped with modern technologies and compatible with the entire installation. Inverters from many manufacturers are available, differing not only in price, but also in parameters. Choosing the right model can be a difficult task, so we have prepared this guide.
What role does an inverter play in a photovoltaic installation?
To make it easier to purchase the necessary inverter, it would be appropriate to first understand what its function is and why this element cannot be dispensed with. Photovoltaic inverters are sometimes referred to as the heart of a photovoltaic installation. It performs several important tasks, on which the proper operation of the entire photovoltaic installation largely depends. The most important process that takes place is the conversion of direct current (DC) generated by solar panels into alternating current (AC), safe for electrical devices. It can also be described as automatic constant synchronization of the installation with the power grid. The inverter is also responsible for recording data such as the amount of electricity produced and the excess supplied to the grid or stored in batteries. Moreover, it optimizes the operation of the installation and protects it from threats resulting from network failures.How are photovoltaic inverters selected for installation?
First of all, the inverter must be correctly matched to the type of installation. There are two main types here. The grid includes those that are connected to the power grid and send surplus electricity generated by photovoltaic panels to it. An alternative to them are autonomous inverters, which are independent of the grid and instead interact with an energy storage device in the form of a battery, which allows you to independently store excess electricity. Hybrid inverters are also available, which can work with both mains and stand-alone installations at the same time. Next, we can divide the inverters into single-phase, producing 230 V, and three-phase, with a voltage of 230-400 V. The general rule is that for installations with a capacity of up to 3.5 kW, a single–phase inverter is used, and for higher power, a three-phase one is suitable for more energy-intensive devices at home.Inverter and photovoltaic panel power
Theoretically, the safest situation should be when the power of the inverter is equal to the maximum possible power of the photovoltaic modules. In practice, you can afford a difference of about 20%. For this reason, some manufacturers of photovoltaic modules recommend that their power be within 80-125% of the inverter's power. This configuration will optimize energy consumption and minimize energy losses. However, you should always carefully check the parameters of all installation elements and their compatibility.
