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]

[FAQS about How many watts does a 18v20w solar panel have]
Solar panels that are used on homes are typically in the 300-400 Watt range. Panels of this size are great for home installations due to their size, weight and cost. While larger, 500 Watt solar panels do exist on the market, the larger size doesn’t necessarily translate to greater benefits. [pdf]
[FAQS about How many watts does a 300x400 solar panel have]
How Many Volts Does a 500W Solar Panel Produce? Typically, with sufficient sunlight hours, a 500-watt solar panel usually generates 20–25 amps/20 volts. They are best for commercial and industrial use, not for homes. Also See: Solar Panel Removal and Reinstall Process [pdf]
[FAQS about How many volts does a 500 watt solar panel produce ]
The rule of thumb is to size your inverter 1.25 bigger than your solar array. In some cases, you may need to use multiple inverters to meet your power needs or increase your system’s voltage. This practice, known as inverter stacking, involves connecting multiple inverters in parallel or series. [pdf]
