3 Types of Residential Solar Inverters

Solar panels are one of the most efficient ways to power your home. If you’re planning to use one, consider the type of inverter you’ll get. To help you out, this article discusses your 3 top options for home solar inverters.

What Is a Solar Inverter?

The electricity that powers appliances is different from the energy generated by solar panels. The former is alternating current or AC; for the latter, it’s direct current or DC. Inverters convert DC electricity to AC, allowing homes to use sunlight as a source of power.

Currently, there are 3 inverter types. By learning how they work, you’ll know which one best suits your needs.

String Inverters

String inverters use a centralized system. All panels are interconnected through different wires, or “strings,” which lead to the main inverter.

They’re easy to install, and, since each panel within converts 100% of the light it receives, they’re also regarded as the most cost-efficient by many technicians.With that said, string inverters completely rely on sunlight. When it’s cloudy, or if shadows block some panels, the electricity produced drastically decreases. So, if you want to use this type, make sure your home is exposed to the sun throughout the day.


The difference between string and microinverters lies in where the inverter is installed. While the former uses interconnected wires, the latter has independent inverters attached to each panel.

The head-on installation allows these units to transform DC power into AC without coursing it through a network, yielding more solar energy than string inverters. You can also add units one at a time, instead of buying an entire system. This makes them ideal if you want to spread your panels at multiple angles around your home to maximize sunlight.

Power Optimizers

If you want the best of both worlds, then use these variants with your PV array. They’re similar to microinverters. But, rather than converting it directly at the source, this system “optimizes” the DC energy in a panel and sends it to a centralized string network to be converted into AC electricity. This results in a more efficient power output because it’s designed for places with limited sun exposure.

String, microinverters, and power optimizers are the most suitable types for home use. To learn more about the right setup for you, or if you want to install a solar panel system yourself, contact a trusted representative of wholesale solar inverters today.
