The working principle of the inverter is to use the power from a DC Source such as the solar panel and convert it into AC power. The generated power range will be from 250 V to 600 V. This conversion process can be done with the help of a set of IGBTs (Insulated Gate Bipolar Transistors).
If we are using a solar system for a home, the selection & installation of the inverter is important. So, an inverter is an essential device in the solar power system. The working principle of the inverter is to use the power from a DC Source such as the solar panel and convert it into AC power.
In off-grid or hybrid solar systems, PV modules may send DC electricity to a solar charge controller first. However, the solar inverter is still an integral part of the balance of the system. (Source: Penn State) Microinverters — also known as module inverters — are generally built into photovoltaic modules.
A solar charge controller is a critical component in a solar power system, responsible for regulating the voltage and current coming from the solar panels to the batteries. Its primary functions are to protect the batteries from overcharging and over-discharging, ensuring their longevity and efficient operation.
However, your home operates using alternating current (AC or “household”) electricity. A solar inverter converts DC to AC electricity. Depending on your system, a storage inverter or power optimiser may also be required. In short, you can’t have a residential or portable solar power system without at least one solar inverter.
A charge controller must be capable of handling this power output without being overloaded. Therefore, it’s essential to tally the combined wattage of all solar panels in the system and choose a controller with a corresponding or higher wattage rating.
