Inverter – a key element of every photovoltaic installation

A photovoltaic installation consists of many elements, the most important of which are: PV panels and an inverter, which is the "heart" of the entire system. The main task of the inverter is to convert the direct current produced in the photovoltaic cells into alternating current, which is required for the operation of most electrical appliances and home systems. The device also allows monitoring the operation of the PV installation, in particular the amount of energy produced annually. A photovoltaic inverter consists of a rectifier, an intermediate and final stage, and protection modules. The control system controls the operation of the device.

Three-phase vs single-phase inverter – which one to choose for PV installation?

There are different types of photovoltaic inverters. One of the divisions is based on the type of current that the inverter produces. In this respect, we can distinguish:
• 1-phase inverters (for single-phase current) - convert direct current into 230 V alternating current;
• 3-phase inverters (for three-phase current) - convert direct current into alternating current with a voltage of 400 V.
The choice depends on the investor's decision whether he wants to produce single-phase or three-phase electricity.

Microinverter – when to use a low-power inverter?

A very important feature of the inverter is power. This parameter should correspond to the number and power of the photovoltaic panels used and the specifics of the system construction. Due to the power offered, inverters are divided into chain, central and microinverters. The latter are devices with low power. One microinverter can support up to several photovoltaic panels, which on the one hand involves the need to invest in a large number of inverters at the start, and on the other contributes to a significant increase in the efficiency of the installation.

Inverter accessories that extend the functionality of photovoltaics

Our assortment includes a wide range of photovoltaic accessories. Some of them are designed for inverters. In this category you will find, among others, keys, connectors, PV energy meters, tips (end caps) and monitoring modules.
