Inverters in Parallel vs. Series

In the realm of inverters, the way they are connected—either in parallel or in series—plays a significant role in determining the performance and capabilities of your power system. Let’s delve into the distinctions between these configurations, breaking down the technicalities into easy-to-understand terms.

Load Sharing in Parallel:

Simple Explanation: In parallel, think of inverters as team players. They work together, sharing the workload like friends collaborating on tasks.

Technical Insight: Parallel inverters share the connected load, combining their capacities. Connecting two 3kVA inverters in parallel, for example, results in a total combined capacity of 6kVA, providing increased power output.

Voltage Increase in Series:

Simple Explanation: In series, inverters are like stacking batteries in a flashlight. Their goal is to increase voltage, not necessarily overall power.

Technical Insight: In series, the voltage output of the inverters adds up. Connecting two inverters in series, each with a voltage of 120V, gives a total voltage of 240V. However, the overall power capacity remains constant.

Overall Capacity – Parallel vs. Series:

Simple Explanation: Parallel is about combining forces for more power, while series is about linking lights for more brightness.

Technical Insight: In parallel, overall capacity increases as inverters share the load, creating a more robust system. In series, while voltage increases, the overall power capacity remains the same.

Design Considerations:

Simple Explanation: It’s like choosing the right tools for the job. Parallel is great when you need more power, while series is useful for specific voltage requirements.

Technical Insight: Designing a system depends on specific needs. Choose parallel for increased power or series for specific voltage requirements.


Simple Explanation: Parallel is about more power together, and series is about adding up voltage. It’s like having different tools in your toolbox for different tasks.

Technical Insight: Understanding the differences between inverters in parallel and series is crucial for designing systems that meet specific power and voltage requirements. Whether you need increased capacity or higher voltage, choosing the right configuration is essential for an efficient and reliable power supply.

In the end, whether you go for the teamwork of parallel inverters or the stacking approach of series inverters, it all comes down to aligning your power system with your unique needs and requirements.
