Solar inverter sizing is rated in watts (W). As a general rule of thumb, your solar inverter wattage should be about the same as your solar array’s total capacity, within the optimal ratio. For example, a 6.6kW array typically uses a 5kW inverter. It is important to get the sizing right so your. .
The easiest way to calculate the solar inverter size you need is to check the DC rating. Typically, the DC rating is the same as the AC output.. .
Oversizing the solar array, sometimes called ‘overclocking the inverter’, means using a lower wattage inverter relative to the PV system’s capacity. This is a common practice. .
The following points need to be considered before you choose your size and start the solar inverter installation process: .
Undersizing a solar array (or oversizing the inverter) means using a solar inverter that’s bigger than the recommended wattage for your solar system. Homeowners sometimes ask about getting a larger inverter to. The typical solar inverter size for a 6.6kW solar system is 5kW. Oversizing the solar array maximises efficiency and a 5kW inverter meets export limit restrictions present in most Australian states.
