Are you going solar and wondering how to choose the best solar inverters for your installation? This comprehensive guide will help you navigate the top inverter brands to find an ideal match for your residential or commercial solar project.

What is a Solar Inverter?

Simply put, a solar inverter is the brains of a solar energy system that converts the DC electricity produced by your solar panels into usable AC power for your home or business. But inverters play other key roles beyond just inversion:

  • Implementing maximum power point tracking (MPPT) to optimize energy harvest from panels
  • Monitoring system and panel-level performance data
  • In "hybrid" models, the ability to convert AC to DC for battery charging

Types of Solar Inverters

There are three main solar inverter designs on the market today:

  • String Inverters - The classic central inverter model with a single inverter box installed at ground level to invert DC to AC power for the full solar array.
  • Microinverters - Advanced panel-level inverters that perform DC to AC inversion for each module, increasing system monitoring granularity.
  • Power Optimizers - Small optimizers under each panel condition DC power before sending to a string inverter, combining panel-level MPPT with a central string inverter.

The three types of solar inverters - string inverters, microinverters, and power optimizers

How to Choose the Best Solar Inverter for Your Installation

Factors to Consider When Selecting an Inverter

Choosing the optimal solar inverter is a decision that hinges on various factors unique to each project. Whether you're outfitting a residential or commercial setup, there are essential considerations to keep in mind when selecting the ideal solar inverters for your installation:
Goals & Priorities - What are your top goals, such as maximizing energy production vs. minimizing upfront costs? Do you need panel-level monitoring?
System Requirements - Does your area have rapid shutdown rules? What are the electrical requirements for your specific project?
Ideal Use Case - Microinverters and optimizers are great for residential rooftops, while string inverters may be more cost-effective for commercial ground mounts.
It's also wise to compare solar inverter costs, quality, monitoring capabilities, and warranty coverage between brands.
Work closely with an experienced solar installer to weigh the pros and cons for your unique situation. They can guide you toward the best solar inverters for your needs.
