( @Doekse possibly you can pass this to the best buy publisher?)

I own a SMA Smart Energy 3.6 inverter, recommended at the [best-buy-guide](https://homey.app/en-nl/best-buy-guide/inverters-and-solar-panels/) section.  
I stumbled upon certain info and have some remarks. I just wanted this to share.

1. Disagree:  
The _con_ is described as “Noisy”;  
I fully disagree on that, for the 3.6 model that is.  
I’m really allergic to fan noise, but this inverter is dead quiet. It has a _ **passive** _ cooling system (see pic below). It does have some internal fans, but I didn’t notice them running yet on the hotter sunny days;  
The only short noises comes from the daily startup/shutdown procedure, when a few loud “click-clacks” can be heard.
2. Not true:  
The 3.6 model has no built-in battery whatsoever
3. Missing info, but very cool:

- When you limit the output power to 0 Watts, the 230VAC output gets activated (with sufficient PV- or battery power).  
This turns it into a 230VAC plug-in device, during mains power outages, or when you don’t want to return power to the grid, but still want to use local solar/battery power.
- it can handle _ **three** _ MPP trackers at once.

Passive cooling:

230VAC off grid output socket:
