Solar Inverters

Solar inverters are not one-size-fits-all. There are different types of inverters, and they each have unique characteristics. The four main types are string inverters, microinverters, power optimizers, and batter-based or hybrid inverters. String Inverters: This is the most common type of inverter. In systems with string inverters, solar panels are connected in a series, or “string.” The DC electricity they produce is sent to one central inverter to be converted to AC. Microinverters: In a system with microinverters, each solar panel has its own dedicated inverter. They convert DC to AC right at the panel, which can lead to increased efficiency, especially if some panels are shaded or face different directions. Power Optimizers: Power optimizers are a sort of hybrid between string and microinverters. Each panel has a power optimizer which conditions the DC electricity, but then sends it to a central inverter for conversion to AC. This option can provide some of the efficiency benefits of microinverters, but at a lower cost. Battery-Based Inverters or Hybrid Inverters: These inverters can draw power from and charge a battery bank, making them ideal for off-grid systems or grid-tied systems with battery backup.

Some important technical specifications and features of solar inverters include input voltage, output voltage, efficiency rate, and power factor. Other factors include the maximum and rated output power, peak output power, AC output voltage, maximum input and output current, peak/maximum power point tracking voltage, starting voltage, weatherproof enclosure rating, and compliance certification.

Choosing the right inverter for your solar system depends on many factors, including your system size, budget, and solar panel placement. It’s essential to remember that an inverter’s efficiency and lifespan impact your solar system’s overall performance. If your solar panel array is simple (for instance, all panels face the same direction and get similar sun exposure), a string inverter can be a cost-effective choice. For complex arrays (panels face different directions, or some get shaded), microinverters or power optimizers might be worth the extra investment for their increased efficiency. Lastly, consider the inverter’s warranty. Since inverters are a critical part of your solar system, choosing one with a robust warranty can give you peace of mind for many years to come.
