Inverters convert direct current (DC) electricity produced by solar panels into a sinusoidal alternating current (AC) of 220V, which is suitable for most electrical appliances. The assortment of inverters for solar systems on the market today is huge.
This equipment is ideal for installation in residential areas, is highly efficient, reliable and durable. Inverters with single-phase and three-phase alternation current output of 220 and 380 V are readily available in our online store. Three-phase models can be used in homes or industrial sites.
The other popular type of inverter for solar panels is the central inverter. It functions similarly to a string solar inverter, but bigger and can handle several strings. They are used in commercial solar systems, where a lot of solar power has to be converted.
The power of such an inverter can reach up to 8000 Watts. To determine the size of the required inverter, you need to calculate the total load of all devices in the power supply grid. To do this, measure the power of each device for 1 hour and summarize the obtained result. Hybrid inverters are most effective for solar systems.
In order to provide grid services, inverters need to have sources of power that they can control. This could be either generation, such as a solar panel that is currently producing electricity, or storage, like a battery system that can be used to provide power that was previously stored.
In a large-scale utility plant or mid-scale community solar project, every solar panel might be attached to a single central inverter. String inverters connect a set of panels—a string—to one inverter. That inverter converts the power produced by the entire string to AC.
Grid-forming inverters can start up a grid if it goes down—a process known as black start. Traditional “grid-following” inverters require an outside signal from the electrical grid to determine when the switching will occur in order to produce a sine wave that can be injected into the power grid.
