There are three types of inverters available: the string inverter, the power optimizer, and the micro-inverter. You would only need one inverter when using string or power optimizers, but using micro-inverters doesn’t require a standalone one. .
You would need to purchase an inverter that matches the output of your solar array, so if you have a 6000W (6kW) system, your inverter would need to a rated at 6000W. You. .
You can connect inverters in parallel to double the wattage (power) or in series to increase the voltage. You could do this if you have several smaller inverters that you want to connect. [pdf]

Your solar inverter should have a similar or slightly higher wattage rating than the DC output of your solar panels (which in this case is 4.5 kW). You can size it between 1.15 and 1.5 times larger. The rule of thumb is to size your inverter 1.25 bigger than your solar array. [pdf]
The average solar panel has an input rate of roughly 1000 Watts per square meter, while the majority of solar panels on the market have an input rate of around 15-20 percent. As a result, if your solar panel is 1 square meter in size, it will likely only produce 150-200W in bright sunlight. [pdf]
