What is a solar inverter and how does it work

In the context of solar energy, the photovoltaic inverter, (also called an inverter) is a vital and strategic component of any photovoltaic system; it is the brain of the system. Its main function is to convert the electricity generated by solar panels, which comes in the form of direct current (DC), into usable electricity for the home or business, which is in the form of alternating current (AC).To understand the importance of solar inverters, it is important to see in detail their functions and their role in a photovoltaic system:

• Transformation from Direct Current to Alternating Current - As mentioned above, solar panels generate electricity in the form of direct current (DC). Although this form of electricity is ideal for collecting and storing solar energy, most of the appliances and electrical devices we use run on alternating current (AC). The solar inverter is the device responsible for carrying out this conversion from DC to AC.
• Electricity quality assurance - Solar inverters also play a crucial role in regulating the quality of the electricity generated. This means that they stabilise the voltage and frequency of the electrical current, ensuring that electrical devices work optimally and safely. They also help protect the power grid by injecting electricity at appropriate phases.
• Maximum Power Point Tracking (MPPT) - Modern solar inverters are equipped with advanced technology such as Maximum Power Point Tracker (MPPT), which optimises solar energy generation. The MPPT continuously tracks changing sunlight conditions to ensure that the solar panels operate at their peak efficiency, thereby maximizing electricity production.
• Monitoring and Connectivity - Many solar inverters today are equipped with monitoring and connectivity systems that allow solar system owners to monitor performance in real time, detect problems and, in some cases, even control the system remotely through mobile applications or web-based platforms.

Battery compatibility

To increase the value you get from your solar system, we usually recommend including a battery. The rates to export electricity back to the grid are much less than the cost to import electricity so it makes sense in most cases to store any excess to use at a later time such as the evening when your system won’t be generating electricity. Solar batteries are a great element of a photovoltaic installation as they help increase savings on electricity bills, since they store the energy produced by solar panels.This means that the electricity produced by the solar panels can be self-consumed instead of being fed into the electrical grid, leading to lower grid energy consumption. To optimize the use of solar batteries we recommend combining Growatt inverters with Growatt batteries. At Otovo we sell various types of Growatt battery models. The full list includes:

• Growatt GBLI6532 (6.0 kWh)
• Growatt GBLI6532 x 2 (12.0 kWh)
