I apologize if this is easy to find information and from what I have found the answer seems to be there is no worry but just trying to cover all my bases. Also full disclosure I’m not even getting a Tesla system, I attempted to but months went by without communication so I’m going with a local dealer, he also says what I’m about to ask is fine. it seems the easiest place to install the inverter and six small batteries would be on the other side of where my power connections are now but inside the garage. Which is a fine location my only issue is I’ve converted the garage into a game room and no one sleeps in there or anyways but for all I tents and purposes is it safe? Both my family and I spend a decent amount of time in there, or perhaps to be safe it can be enclosed by something?

Any side effects to where inverters/batteries are placed in the home?

It has been covered in some detail in other threads. One of the resident experts @Vines or @wwhitney is probably best able to answer this.
My quick recollection (based on their great posts) is that installation in living spaces is not allowed, but the ultimate authority is your local AHJ (Authority Having Jurisdiction).

Do you need fire suppression for 3x Powerwalls in Northern California?
Yes, 9540A is the standard for "Evaluating thermal runaway fire propagation in battery energy storage systems" If you dig into the text of the new R327 this is the standard required, to justify closer ESS separation than 3' OK, I just reviewed the currently published versions of CRC R327 and...

Powerwall mounted inside or outside?
I'm having solar and the powerwall installed in a couple of weeks and my intention is to have it installed outside. This is what we planned for and I think it will be the best overall location for me. East facing wall and right next to my meter. They told me being outside has no net effect on...

Great info here but wanted to emphasize it is up to your local authority ( as @BGbreeder pointed out ) .. I believe these references are all for certain counties in CA (i apologize if incorrect I'm going from memory of threads) .. even within CA there are many much less restrictive jurisdictions .. I have dealt with AZ on a few moderate home improvement projects including electrical and they have very few regulations compared to CA .. some counties could of course differ but generally this holdsIt has been covered in some detail in other threads.

Thank you for all of your replies, it seems where I am located this is not going to be an issue. But besides a possible fire hazard, I do have a smoke and co detector in the garage, no other possible issues? As I said the garage is now a game room so family is often there, no reports of harmful “rays” or anything from the equipment? Inverter, batteries?

not unless you are on the electromagnetic train ... but in that case not sure why you would have electricity in your home at all ... think saul goodman's brother

sorry i was referencimg the fear some ppl have of electromagnetic energy .. basically and oversimplifying it anything with an electical charge radiates this as a function of the distance and the energy level so for some being anywhere near something like a powerwall would freak them out ( also this type of energy hits the earth constantly with the atmosphere blocking most ) . i mean i would not mount them in my bedroom for many other reasons ... but often the "danger" of electromagnetic fields to a person in the power range consumers are exposed to is unfounded by any evidence based medice but of course this does not stop speculation by many esp on the interwebs
and firecodes are no doubt reason for not installing in living spaces .. a fire from a powerwall although exceedingly rare is still possible ... despite fact that, for example clothes dryers which can usuallly be installed in code within living spaces cause many more fires often due to lint accumulation (still statistically low)

The code concern is primarily fire risk, but consider the number of exit routes from the garage (life safety), and the fact that the combustion fumes aren't exactly BBQ smoke. A Powerwall has the equivalent of a quart of gasoline in electrical energy, plus all of the electrode components that are themselves flammable.
Personally, I would not install Powerwalls in an occupied space, any more than I would store propane, gasoline or paint thinner in the house, either.
Here is a video on fighting a battery fire in a Tesla, granted way more batteries, but it takes a ton of water to cool the batteries, and there is a ton of smoke. Inside a garage is going to be way harder in my amateur opinion. Why go there?

My reason for going to the garage is because I’m in Phx, too hot to go outside. My garage is now a game room and completely enclosed and insulated because again I’m in phx and I don’t like to sweat bullets while playing lol. So the only exit is the door to the house but the solar equipment would go on the opposite side of the door to the house by the garage door. I have a smoke and co detector and fire extinguisher in there.

yea i would have no issue putting powerwalls in garage as you describe esp given phx summers .. just as i had no issue working out in my garage during height covid restrictions .. as you said no one sleeping in there ...what you local codes say i dont know

i am not aware of any gas or venting put out by a powerwall in normal operation .. i know they have a cooling fan that comes on certain times but that is to cool a sealed liquid system .. perhaps someone on here knows better
There aren't any gases other than atmospheric air that we all breathe which are regularly vented from the Powerwalls. As @Electrph mentions, there is a liquid cooling system with fans that make a little noise. When we were first planning on Powerwall installation locations in our garage, they originally mentioned not wanting to install them on walls where there was habitable space on the other side due to the low hum of the cooling fans/pumps.

not trying to split hairs but i think it is the liquid pumps that make the most sound / vibration ( extremely low level) as opposed to actual fans ..
i like the sound i find it soothing
