ON-GRID INVERTERS

Inverters used in solar systems are divided into two. Off-Grid inverter and On-Grid inverter.

ON-GRID INVERTERS

The inverter is the heart of grid-connected systems. Inverters are electronic devices that convert DC electrical energy into AC electrical energy. There are three types of off-grid photovoltaic systems: square wave, modified sine and full sine. Modified sine and full sine models are frequently used in solar systems.        

The modified inverter does not give pure sine output wave like  full sine inverter. Therefore, it is not recommended to be used in more sensitive motor devices such as refrigerators, washing machines and pumps. Modified sine inverter can cause such sensitive devices to deteriorate over time. Their prices are more affordable than full sine inverters.

The full sine inverter outputs the dc voltage from the batteries in the form and frequency of the mains wave. The efficiencies of Full Sine wave inverters range from 89 to 94. Working frequencies are also 50/60 Hz. Full-sine inverters are used more commonly than modified inverters because they provide trouble-free operation in motorized loads such as refrigerators, hydrophores, washing machines. At the same time, the use of this inverter is preferred due to its high inrush feature in the operation of high current devices such as compressors.

Inverters full sine models are two types, MPPT and PWM. New generation inverters used in solar systems are smart inverters that also include a charge controller. This type of inverters show the user the production information of the solar panel, battery voltage values, electricity usage. These inverters contain a convector (AC-DC converter) so that batteries can be charged with mains or generator support.  Inverters used in solar systems are divided into two. Off-Grid inverter and On-Grid inverter.

Converts the electricity received from solar panels into single-phase or three-phase AC electrical energy according to the electricity grid. Grid-connected inverters are available in separate inverter models for three phases. These inverters are specially designed inverters. It works with the power coming from the solar panel and the power coming from the grid. The reason for this is to support the consumption load with mains electricity when the power drop occurs on the solar panel. As is known, solar panels do not produce electricity at full capacity at all hours of the day. Because the panels receive radiation from the sun at a fixed angle. With the rotational movement of the Earth, the position of the sun in the sky and the angle with the earth change. In case of power drops caused by this factor, power consumption from the grid is supported by the inverter. At night, the electricity supply meets the consumption directly from the Grid network. By connecting a data logger to the inverters, the user can monitor the electrical power production and consumption  anywhere in the world from his mobile phone.

On-Grid inverters used in grid-connected are different then Off-Grid Inverters. These inverters are specially produced for Grid network connections. It has features such as being able to work in coordination with the network, providing electricity transfer from the network to the load as a result of the power drop in the panels. These are available in single and three phases. In these systems, the inverter power should be parallel to the panel power, unlike off-grid systems

Grid Connected Full Sine Wave Inverter: With the developing technology today, inverters have become more useful and solution oriented. The grid connected inverters (smart full sine inverter), which have been widely used in solar energy systems recently, work in sync with the grid rather than away from the grid like other off-grid inverters. Although there are no charge controllers in the other off-grid inverters, mains connected full sine inverters also direct the electricity from the solar panels to the battery charge by passing it through the charge controller. At the same time, one of its biggest features, even the most important feature, is to ensure that the energy need continues without interruption by taking electricity from the grid where it is automatically connected when there is no energy left in solar panels and batteries. Smart Sine inverters can be used very efficiently not only in the grid but also in remote locations.

power should be greater than the sum of the powers you will use in your system. If you want to make the most ideal choice when buying an inverter, you will need to know the power consumed by the devices you will use in the system. The inverter will have a working logic, it must be higher than the sum of the power of the devices that are running or will be running at the same time.
