Solar Panel Inverter Types, Pros, and Cons

Solar energy is a clean and renewable energy source that many people are beginning to use in their homes. To harness the power of solar energy, you need more than just solar panels – you also need an inverter. An inverter is responsible for changing direct current (DC) from your solar panels into alternating current (AC), which can then be used in your home or business. It is important that you understand the different types of inverters available on the market so that you can choose one that best fits your needs. In this blog post, we will discuss different types of solar panel inverters, and their pros, and cons. 

Types of Solar Panel Inverters

The type of inverter depends on how it connects to other components within a photovoltaic system such as batteries, charge controllers, and load centers. The most common types include off-grid/standalone systems, grid-tied/on-grid systems with battery backup options, hybrid systems with battery backup options, etc. Each type has its own advantages and disadvantages: 

Off-Grid/Standalone Systems – These are standalone systems not connected to the electrical grid; they require no utility connection but do require a backup generator during periods when there’s insufficient sunlight for charging batteries or powering appliances directly from the PV array. 

Grid-Tied/On-Grid System with Battery Backup Option – This setup works by connecting directly to existing utility lines while also using stored electricity generated by PV arrays if needed during peak usage hours or at night time when sunlight isn’t available. 

Hybrid System With Battery Backup Option – A hybrid system combines both stand-alone configurations along with those connected utilities providing users flexibility between both sources depending on conditions present at any given moment.

When it comes to solar energy systems, the inverter is one of the most important components. It takes in direct current (DC) power from the photovoltaic panels and converts it into alternating current (AC), which can be used by home appliances and fed back into the grid. There are several types of solar panel inverters available on the market today—each with its own advantages and disadvantages. Let’s take a look at some of them: 

String/Central Inverters:Pros & Cons

String/central inverters are one of the most popular types for residential applications due to their low-cost option compared to other options such as microinverters or string inverters with built-in optimizers. They have an easy installation process since they require fewer parts than other options; however, they do need an exact match between DC voltages when installing multiple strings together in order for maximum power output to be reached.


  1. Lowest cost option
  2. Easy to install and maintain
  3. Durable, long-lasting life cycle
  4. High-efficiency levels
  5. Can handle large systems
  6. Lower voltage output than other types of solar inverters         
  7. Very reliable
  8. Ability to monitor energy production remotely through an app or web portal
  9. Works best in cloudy weather
  10. Can be built with inexpensive components
  11. Quick installation time due to fewer parts needed


  1. Maximum power output can only be reached when all modules are performing optimally
  2. The difficult system design process as there needs to be an exact match between DC voltages
  3. Sensitive to ambient temperatures
  4. Output cannot easily expand if more solar panels are added after installation
  5. Not suitable for homes where roof space is limited
  6. Does not offer access control features like those available on microinverters
  7. Limited ability for fault detection and diagnostics
  8. Limited monitoring capabilities compared with micro inverters
  9. Not compatible with most battery storage systems 
  10. High replacement costs when repair or maintenance is necessary

Micro inverter: Pros & Cons

A micro inverter is a type of inverter used in photovoltaic (PV) systems to convert the direct current (DC) produced by individual solar panels into alternating current (AC) that can be used by appliances or fed back into the grid. Unlike string inverters or central inverters, which are connected to multiple solar panels, each micro inverter is connected to a single solar panel.


  1. Highest efficiency rates among all types of solar panel inverters
  2. Allows maximum power harvest from each individual module
  3. Each module operates independently which allows shading issues on some panels not to affect others
  4. Suitable for roofs that have partial shade or irregularly sized spaces
  5. An ideal choice for complex roof designs such as skylights, dormers, chimneys, etc.
  6. Easier system design due to its modularity
  7. The fault detection feature alerts users quickly about any problems in the system
  8. Compatible with most battery storage systems
  9. Access control features allow you to customize your home’s energy usage
  10. Monitoring capabilities provide detailed data regarding the wattage produced by each module
  11. No need for string configuration because it works even if one panel does not perform optimally
  12. Reduced risk of total blackout since no single point could cause an entire system failure
  13. Installation time is significantly reduced since no extra wiring is required
  14. Quieter operation than string/central inverters
  15. Flexibility in expanding your existing array size without affecting performance
  16. Can produce both AC and DC current according to user requirements
  17. Longer warranty period compared to other types


  1. Higher initial cost compared with string/central type
  2. More complicated maintenance procedures
  3. A not ideal solution where high voltage output over 600 volts needed
  4. Increased complexity makes troubleshooting difficult
  5. More susceptible environmental factors such as dust and moisture accumulation
  6. System safety measures must be taken into account during the planning stage (such as grounding wires etc…)
  7. A higher degree of hardware reliability required compared to string/central type

Hybrid Inverter: Pros & Cons

A hybrid inverter is a type of inverter used in solar PV systems that can manage both grid-tied and off-grid power systems. It is designed to work with battery storage and can switch between grid-tied and off-grid modes depending on the availability of solar power and grid power. Hybrid inverters can be used for both residential and commercial applications.


  1. Cost-effective solution for small and medium-sized installations 
  2. Efficiently handles both AC and DC current due to its dual-mode architecture
  3. Combines the advantages of both microinverters and central inverters
  4. Suitable for both residential as well as commercial applications             
  5. Possibility of adding solar panels in the future without replacing existing systems
  6. Flexible design options available (e.g., can be used with batteries or grid-connected)
  7. Expansion capabilities allow users to increase the output wattage by adding extra modules
  8. Monitoring features provide detailed data regarding the performance
  9. Quieter operation than other types
  10. Easy system planning due to minimal wiring requirements
  11. Lower maintenance cost since it does not require regular cleaning
  12. Compatible with most battery storage systems
  13. Longer warranty period compared with other types


  1. Higher initial cost than string/central type
  2. Limited access control features when compared to microinverters
  3. Not an ideal solution where a high voltage output of over 600 volts needed
  4. Maximum power harvesting is limited unless all modules perform optimally
  5. More susceptible environmental factors like dust, moisture accumulation, etc…
  6. The high degree of hardware reliability required
  7. System safety measures must be taken into account during the planning stage (such as grounding wires etc…)

All in all, deciding the most suitable form of solar panel investor depends on the unique needs of a particular situation a buyer wants to meet, whether additional protection is needed to support a potential power outage, a sudden drop in the production of a rooftop array due to dense shading buildup such as nearby foliage. The trade-offs must be carefully weighed and ordered with the mind to ensuring maximum efficiency is guaranteed while properly balancing financial constraints to prevent budget overstretch. However, there is a desire to wait longer means potentially saving a lot of money in the future.

Consider the time account now and trade off the long-term basis on which the investment lasts. Not a hasty decision to regret maybe down the road to an avoidable degree.
