For those that don’t want to click the link herea the important part of what they are:
The main advantage is that they electrically isolate the panels from one another, so small amounts of shading, debris or snow lines on any one solar module, or even a complete module failure, do not disproportionately reduce the output of the entire array. Each microinverter harvests optimum power by performing maximum power point tracking (MPPT) for its connected module.[14] Simplicity in system design, installation, lower wire amperage, simplified stock management, and added fire safety are other possible benefits.
The primary disadvantages of a microinverter include a higher initial equipment cost per peak watt than the equivalent power of a central inverter since each inverter needs to be installed adjacent to a panel (usually on a roof). This also makes them harder to maintain and more costly to remove and replace. Some manufacturers have addressed these issues with panels with built-in microinverters.[15] A microinverter often has a longer lifespan than a central inverter, which will need replacement during the lifespan of the solar panels. Therefore, the financial disadvantage at first may become an advantage in the long term.
The lower wire amperage, and fire safety where my major reasons for choosing such a system. DC and high power is dangerous when compared to similar power in AC systems.
I’m also one of those people that like to see what the individual panel is doing and logging the data
Smart, I think a lot of people though still don’t really know about this setup. I only learned about the benefits yesterday. It really pays to dig a bit deeper, especially for someone making a big decision to invest and install solar.
I’ve had a micro inverter solar setup on my roof for a few years now.
Super happy with it.
Yes, the initial outlay is more expensive, but not by much. The other thing your missing is the noise. Some large inverters make noise apparently, the micro ones do not. This was one of the main draw cards that pushed me to go this way.
Yeah micro inverters are pretty useful for the vast majority of installs. Most people don’t know that if one panel of a regular install gets shaded your entire string loses output, not just that single panel.

Do you have batteries?

There are also MOSFET based bypass panels that can achieve a similar effect at a far cheaper price point. Quite common here in Aus.
The high voltage DC strings are dangerous, but very price + power efficient and our install and wiring rules have made it quite safe.
Great explanation. Thanks!
