[FAQS about Harare Solar Inverter Price]
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 big an inverter should I use for a 50w solar panel]
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]
