6 FAQs about [Photovoltaic inverter 2 times over-matching]

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.

Can a solar array be oversized relative to the inverter rating?

To maximize a solar project’s value, it can be advantageous to oversize the array relative to the inverter rating to increase system output in partial production conditions. We use the term inverter loading ratio (ILR) to describe this ratio of the array’s nameplate DC power rating to the inverter’s peak AC output rating.

Should a solar inverter be oversized?

However, slight over-sizing of the solar panels compared to the inverter capacity (up to 133% under certain guidelines) can sometimes yield better overall efficiency due to the variable nature of solar irradiation throughout the day. The ratio for inverter sizing often depends on specific system requirements and local regulations.

What happens if you oversize a PV inverter?

And when oversizing a PV array an inverter will be more often operate at or close to its rated AC output power, heat generation from the inverter may create an issue for the installation location especially if inverters are installed in a plant room or similar where air flow and heat dissipation might be limited.

What is inverter matching for Trina Solar's vertex series photovoltaic modules?

Trina Solar’s inverter matching for the Vertex Series photovolvoltaic modules is discussed in the White Paper on 'Inverter Matching for Trina Solar’s Vertex Series Photovoltaic Modules'. Specifically, the DEx21 series modules, which have a 66-cell layout and a maximum power of 670W, are the subject of the discussion on inverter matching for utility-scale projects.

Why do solar inverters have a higher ILR?

Higher ILRs increase the utilization of the inverter, thereby decreasing the inverter costs per kW h of AC output. The drawback to increasing a project’s ILR occurs when the inverter is power limiting (i.e., when the power from the solar array exceeds the inverter’s rated input power).
