The advantages of Micro Inverter when choosing to install it in a residential home. Usually, the equipment that is like the heart of the Solar Rooftop system, aside from the solar panels, is the Inverter. There are usually 2 main types to choose from: String Inverter and Micro. Inverter
The difference between these two types of Inverter Solar Rooftop systems is the principle of connecting the solar panels in the system. Normally, installing a Solar Rooftop system will definitely require installing more than 1 solar panel in order to increase the production of electrical energy for use within the home. There are two types of solar panel connections according to the Inverter selection.
The String Inverter system connects solar panels in series. Or what we call a Series connection. By connecting solar panels like this, the DC voltage level or Vdc will increase as the number of solar panels connected increases.
On the other hand, if it is a Micro Inverter system, the solar panels will be connected in parallel. By connecting the solar panels in this way, the voltage level will be equal to the voltage of a single solar panel. Instead, it increases the current level of the system.
From the above explanation, it can be seen that the overall Micro Inverter system will have a higher efficiency in producing electrical energy than if only some of the solar panels were obscured by the shadow. It will cause just that panel to reduce the efficiency of electricity production. It will not affect other solar panels in the system. This makes the Micro Inverter system guaranteed to produce 5-30% more electrical energy than traditional String Inverters.
Additionally, the Micro Inverter system has something called MPPT(Maximum Power Point Tracking) or the maximum power tracking point on each port connected to the solar panel. Therefore, it means that connecting independent ports will make the installation of a residential solar rooftop system more cost-effective in using the installation space. Because as you know, residential homes have points that need to be considered, namely the installation space and the direction at an angle to receive sunlight, which is often forced according to the direction of the house This may cause it to be more or less an obstacle to installing a Solar Rooftop system. But this does not affect the Micro Inverter because we can install solar panels in the same system freely without having to connect them all together into the same system like a String Inverter system.
Micro Inverter is convenient for maintenance and additions to the system in the future. Because of the installation with the Micro Inverter, the system can be administered through the application and can view the system as a whole and can also view the operation of individual solar panels or Module Level Monitoring.
