Central Solar Inverter: Secret Weapon for Unlocking the Potential of PV Systems

Photovoltaic or PV systems are becoming the new norm of energy generation. The role of a PV system is simple – to capture the solar rays and convert them into usable electrical energy. However, it is not as simple as it is said. 

Before you can light your table lamp with that electricity, the panels and the electrical grid require another step. That’s where central solar inverters step into the spotlight. These inverters are the secret weapons that hold the key to unlocking the full potential of PV systems. They convert DC into AC current, which powers your lamp. 

This shift towards cleaner and sustainable energy sources is undoubtedly exciting, but with new technologies, hidden challenges are always there. In the case of PV solar panels, the challenges include the conventional operation with maintenance hurdles. This article is about understanding these challenges and finding the once-and-for-all solution. 


O&M Problems Related To Conventional Central Solar Inverters 

Handling a central solar inverter is challenging, especially when it is as large as a hut and far away. Thus, due to extreme operating conditions, many operational and management problems can come with this PV system upgrade. Some of these problems include:

1. Geographically Remote, Decentralized Locations

The first problem with central inverters is their remote, decentralized location. These systems are often set up in far-off places like remote rural areas, deserts, or islands to shield from heavy voltages. Although it is for the safety of the grid and the people, reaching these spots for regular check-ups, fixings, and maintenance can be challenging.

2. Non-automatic, High Labor Cost

A central solar inverter requires a skilled and professional trainer with specialized equipment for regular O&M operation. Getting these services is complicated with a high labor cost.   

3. Harsh Environment

Solar setups are installed in the open, where they encounter all sorts of weather antics — dust, humidity, temperature swings, gusty winds, and even lightning crashes. These harsh conditions make the inverter maintenance more difficult to perform regularly, shortening their lifespan.

4. Limited Scalability

A central solar inverter has a fixed power and voltage rating. This feature limits the scalability and flexibility of the entire PV system. If you wish to grow the solar generating capacity, you might have to install another central or replace it with a bigger one.

5. Downtime Losses

Crashing your central in a PV system means blowing off the entire system, not just your inverter. It means no electricity production, which means downtime losses and less cash in your pocket.
