A solar inverter is a vital component in your solar power system, converting the direct current (DC) electricity generated by solar panels into the alternating current (AC) electricity used in your home.

Types of Solar Inverters: Pros and Cons

Types of Solar Inverters

1. String Inverter


Also referred to as a ‘central’ inverter, the string inverter is a fitting choice for straightforward solar power systems.


  • Connects a group of solar panels (referred to as a string) to a central inverter.


  • Easy maintenance, typically located in accessible areas like basements or garages.
  • Cost-effective for basic roof layouts with consistent sunlight.
  • Durable and boasts a straightforward setup.


  • Underperformance in one panel impacts the entire string.
  • It could be more conducive to roofs with shading issues or intricate designs.

2. Microinverters


Microinverters stand out as distributed inverters installed adjacent to each solar panel.


  • Converts DC to AC electricity right at each panel.


  • Ideal for complicated roof designs or areas with consistent shading.
  • Maximizes each panel’s performance independently.
  • Facilitates easier system expansion over time.


  • Higher cost compared to string inverters.
  • Maintenance can be challenging due to rooftop placement.

3. Power Optimizers


Power optimizers strike a balance between string inverters and microinverters.


  • Optimizes electricity voltage before sending it to a central inverter.


  • Mitigates shading effects on individual panels.
  • Suitable for complicated roofs with obstructions.


  • Higher cost compared to basic string inverters.
  • Maintenance can be more intricate.

4. Hybrid Inverter


The hybrid inverter is a recent addition, combining features of a PV inverter and a battery inverter.


  • Converts DC from solar panels to AC for home use and vice versa.


  • Allows bidirectional electricity conversion.
  • It is ideal for energy backup and is compatible with solar batteries and electric vehicles.
  • Enables storing energy during low-rate periods for later use.


  • Higher cost compared to traditional inverters.
  • Limited adaptability to complex roof designs or shading.

Choosing the Right Inverter

  • String Inverter: Optimal for a lower cost and basic roof layouts with consistent sunlight.
  • Microinverters: Ideal for complex roof designs, shading issues, and easy system expansion.
  • Power Optimizers: Suitable for complicated roofs, offering improved performance without the cost of microinverters.
  • Hybrid Inverter: Excellent for those considering energy storage or planning to charge an electric vehicle using solar power.

Understanding of these solar inverters empowers you to make an informed decision based on your unique requirements. For personalized advice, it is advisable to consult with a reputable solar installation company.
