Technical FAQs 4

How much does an 80% efficiency inverter cost?

An 80% efficient inverter produces 140,000 kWh, with a value of $25,191, losing $6,298. While a 100% efficient inverter is unrealistic and 80% is unacceptably low, this context helps to understand the efficiency impact. The difference between 98% and 96% efficiency equates to approximately $600 over 25 years, or about $24 annually.

What is the efficiency of a PV inverter?

The efficiency of the inverter may vary depending on the input power and voltage of the PV array. The nominal efficiency is indicated in the manufacture specifications and is the value during operation in the nominal inverter voltage range and at a partial load of about 50%–80% of nominal power.

How efficient is a solar inverter?

The efficiency of a solar inverter significantly impacts the total energy produced by a solar installation. Since all the electricity generated by the installation passes through the inverter, its efficiency is crucial. For instance, with an 80% efficient inverter, 20% of the electricity is lost, while a 98% efficient inverter only loses 2%.

Why do solar inverters have CEC efficiency?

Since solar energy input varies during the day (like when there’s indirect sunlight), the CEC efficiency accounts for how the inverter handles different power levels and voltages. This gives you a better idea of the inverter’s actual efficiency on an average sunny day, instead of just its ideal performance.
