How do I choose a solar inverter size?
To calculate the ideal inverter size for your solar PV system, you should consider the total wattage of your solar panels and the specific conditions of your installation site. The general rule is to ensure the inverter’s maximum capacity closely matches or slightly exceeds the solar panel array’s peak power output.
What wattage should a solar inverter be?
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.
How much solar power can a 5kw inverter produce?
Under the Clean Energy Council rules for accredited installers, the solar panel capacity can only exceed the inverter capacity by 33%. That means for a typical 5kW inverter you can go up to a maximum of 6.6kW of solar panel output within the rules.
What size inverter do I Need?
Inverters come in different sizes starting from as little as 125 watts. The typical inverter sizes used for residential and commercial applications are between 1 and 10kW with 3 and 5kW sizes being the most common. With such an array of options, how do you find the right size for you? An inverter works best when close to its capacity.
Are solar inverters the same size?
No, solar inverters are not the same size, as the size you need will depend on the generation capacity of your solar array. There is no one-size-fits-all inverter, as the size affects the unit’s efficiency and larger inverters are more expensive. The easiest way to calculate the solar inverter size you need is to check the DC rating.
What should be the maximum DC input power of a solar inverter?
The general guideline is to choose a solar inverter with a maximum DC input power of 20-35% greater than the total capacity of the solar array. Having a buffer capacity will prevent having to upgrade your inverter later to accommodate additional panels.
