6 FAQs about Inverters and Microinverters

What is the difference between a string inverter and a microinverter?

In contrast, string inverters are normally paired with optimisers to conduct module-level optimisation and monitoring of solar panels. Both have their advantages and disadvantages when it comes to installation, monitoring, and maintenance of the solar system. Both string inverters and microinverters work by converting DC power to AC power.

Are microinverters better than traditional solar inverters?

Other Inverter Technologies Microinverters boast many remarked advantages over traditional solar inverters. In a string inverter solar project, all solar panels are connected in series and attached to the central string inverter.

What are solar microinverters?

Microinverters are small electronic devices that convert direct current (DC) into alternating current (AC). One microinverter could fit the palm of your hand. The main factor differentiating microinverters from traditional inverters is that they operate at the panel level rather than the solar panel system as a whole.

What is a microinverter & how does it work?

What are microinverters? A microinverter works by attaching to the back of each individual solar panel and is responsible for converting the DC power produced by that specific panel into AC power. Some microinverters can connect to more than one solar panel.

Should I choose a string or microinverter?

Choosing between string vs. microinverters will depend on the constraints of your project. If you can install your solar panels so they have consistent, full sun, string inverters may be the best choice. However, if parts of your solar system will be shaded throughout the day, you are better off choosing microinverters.

How much does a microinverter cost?

Microinverters typically cost a couple of hundred dollars per unit. While they offer many advantages, which we will cover further, microinverters are notably costlier than string inverters when installed on an entire solar power system.
