How To Choose The Right Size For A Residential Solar Inverter?

 Solar inverters are available in a wide range of shapes and sizes. These are marked in Watt ratings. This rating states the amount of solar power the inverter can convert in a given period.

The watt rating of your solar inverter must be approximately equal to the amount of power produced by your PV array. 

Importance of a solar inverter

The function of a solar inverter is to convert the DC power produced by the solar panel to AC.

The significance of this conversion is that our home appliances cannot utilize direct current (DC) and run on alternating current (AC). An inverter converts this DC to AC and supplies it to the household.

If the watt rating of a converter is not at par with the power production capacity of the panels, then sustaining the household work will become problematic. Hence, solar inverter sizing is essential for efficient performance and profitability.

How to calculate the right size for a solar inverter?

When it comes to a solar inverter, some companies offer these in the PV module package. But for others, you need to buy them separately. In the latter cases, getting the size of your converter right can be difficult.

A solar inverter's size might differ from that of your array. It can be higher or lower. Choose the array to inverter ratio to determine if your module's solar inverter size is correct.

To calculate this, divide the module's DC rating by your converter's maximum AC rating. If the result is around 1.15 to 1.25, you have the right size for your inverter.

The energy production is higher than the conversion rate can overwhelm the inverter. This is referred to as clipping. If this happens, the device limits its conversion rate according to its capability, which leads to power loss.

Hence buying a lower size unit is not recommended. And so is for higher size units, since purchasing a more extensive unit does not provide any additional benefit but comes at a higher price. So the cons are dominant over the pros.

So, it is best to buy an inverter that has a conversion rate equal to the panels’ production rate is best.
