There are several questions that need to be answered. The most important are the following.
If your area is sunny, there is no need to use a small inverter. Otherwise, expanding your solar panel is a good way to maximize inverter capacity. If you want to add more photovoltaic panels, look for those with an efficiency rating of at least 20%. If you want to replace the inverter and get the largest unit, you can afford it. Whether you are on the grid or not, the larger the capacity is better than the smaller the capacity. It's also easy to find the ideal size. Check your monthly electricity bill and calculate the average usage. Plus at least 10% of the total, you have your inverter size.
Do you have any plans to expand the use of solar energy? Maybe you're tied to the grid now, but plan to leave the grid in a few years? It may be a good idea to invest in a high-capacity inverter today. So if you decide not to rely on the energy system, you'll be ready.
Once you decide what inverters and solar panels to buy, it's time to install them. Unless you are a DIY expert, it is best to let a professional installer deal with this problem to avoid any potential problems.
The specifications will vary so make sure to check the inverter before connecting any solar panel. Generally speaking, the inverter can handle 30% more power than the rated power. Considering that solar panels are not always generated at peak power, this should not be a problem.
The larger the solar array, the more effective the overclocking. But you must also check the DC voltage input of the inverter. Temperature is also important because the inverter is designed to operate within a specific temperature range.
If you plan to upgrade your solar system, check other parts as well. We focus on inverters and solar panels here, but if you add more photovoltaic modules, solar controllers, fuses and wires may also need to be upgraded.
