solar inverter system, and a mounting structure to hold everything in place. Depending on the system and an electric meter, they may also include a battery. The number of panels for each system will vary depending on the required energy production.

Working of a solar inverter system

One of the most important components of a solar PV module is a solar inverter. It transforms the rays of the sun into usable electricity that may be used in your home or place of business.

The fluctuating direct current (or “DC”) from your solar panels is fed into the inverter, which converts it into alternating 120V/240V current (or “AC”) output. It must convert the DC output generated by your panels because the appliances in your house operate on AC rather than DC.

The sun falls down on your panels, also known as photovoltaic (PV) cells, which comprise a number of semiconductor layers of crystalline silicon or gallium arsenide. These layers, which are linked together by a junction, combine positive and negative layers. The semiconductor layers capture sunlight and transmit it to the photovoltaic cell.

Direct current (DC), a type of electric current created by the movement of electrons between the positive and negative levels as a result of this energy, is produced. Depending on the kind of system you have, this energy is either supplied immediately to an inverter or stored in a battery for later use.

Although your home needs AC, the energy is in DC format when it is transmitted to the converter. The energy is captured by the inverter, which then passes it via a transformer to produce an AC output.

Different types of solar inverter system

At Discover Solar, we offer four different types of inverters. String inverter — These inverters are both the most prevalent and the most economical. Since each string connects the panels to the inverter, they are rightly named as ‘string’.They are appropriate for houses with uncomplicated roof designs that are frequently exposed to sunlight. The typical warranty period for string inverters is between five and ten years.

Microinverters — There isn’t even a single point of failure in microinverters, which increases the efficiency of the overall solar power system.They offer 25 years of guarantee and panel-level monitoring and optimization. Homes that receive a lot of shade and have complicated roof layouts are good candidates for microinverters.

Hybrid inverters — As they permit connecting batteries to the solar power system, these inverters are multi-mode.A hybrid inverter interacts with the battery and manages its charging and discharging using a method known as “DC coupling.” They perform amazingly, particularly when coupled with battery storage.

Optimizer system — Each panel’s power output can be separately and inexpensively optimized with optimizer systems. Each panel contains DC power optimizers attached to the rear that maximize its performance and guarantee that the performance of the other panels won’t be impacted if one panel is partially shadowed or compromised in any other manner.The solar inverters offered by Discover Solar are CEC approved, thus ensuring that they are 100% fully Australian owned.They come with several years of warranty and durability to give you nothing but only the best so that you get the most out of your investment.
