6 FAQs about [Replacement of photovoltaic central inverter]

Should PV systems be replaced by inverters?

As the number of PV systems already in operation for several years grows, demand for “revamping” by replacement off all the inverters in a project is estimated at several gigawatts per year and expected to increase rapidly through the 2020s. There are a number of reasons why project owners are taking interest in this strategy.

Can a 600 V central inverter be replaced?

Optimizer manufacturer Alencon has published a paper outlining the technical challenges to replacing the largely obsolete and frequently failing 600 V central inverters used in older PV projects. Things fail with age, whether they be cars, phones or inverters.

Should a new inverter be replaced?

Revamping a project with new inverters has already been shown to pay off, and as demand begins to broaden from regions such as Italy, Germany and Spain that have a larger based of projects more than five years old, pv magazine is partnering with Sungrow to take a look into the advantages and potential pitfalls of inverter replacement.

Can a Fronius inverter restore a photovoltaic system to full power?

However, through efficient repowering, you can quickly and easily restore your photovoltaic systems back to full power. Fronius inverters are the ideal replacement for older devices that are no longer operating at full capacity. They are easy to install and significantly increase the yield and service life of photovoltaic systems.

Why do project owners want to buy a new inverter?

There are a number of reasons why project owners are taking interest in this strategy. In some cases, older inverters may simply be underperforming, or may be struggling to get hold of replacement parts for models no longer manufactured or suppliers that have since left the market.

Can a string inverter be replaced?

Additionally, many companies that were leading manufacturers at the time do not exist anymore, meaning that direct hardware replacements are now impossible. In replacement, string inverters are the logical choice, as they provide a similar power rating, but they lack the isolation transformers present in central inverters.
