Power Production This Time of Year!

Past few days have been foggy in the morning but clear during the day with decent production. Got up this morning with the batteries at 85% and mild temps, so no real need for heating or cooling. Cold front coming in later today so we will be turning the heaters back on soon.

By the end of today we will have used about 3500kWh of solar power from our system.

EDIT: to add that we bought 9750kWh from the grid, so, we made about 1/3 of the power we used last year.

At first I thought you were talking about 3,500kWh in a 24hr day….lol

yes lots, one is parked in the Car-Port outside my shop!
But as others noted, the regulations for the battery in the car and the battery in the shop come from different authorities - Australia too I expect.

Under the current regulations, the CEC would dictate my max DIY battery size allowed 'in a dwelling' is 1kWh. (already violated by the five or six 18650 E-Bike batteries I built six years ago 3-7 kWh each), With factory CSA-approved server rack batteries I could go to a total of 80 kWh under the existing regulations, if Each stack was max 20kWh, and separated by 1m (3-feet), since the shop is not attached to a dwelling. Our electrical code is up-dated every 3-years, and I am told there are some changes coming to reflect the safer LFP batteries, but the current rules date from L-ion. So being 'progressive', I decided to just adopt the new regulations that should eventually come into affect and let them catch up to me ! (LOL).

The US NEC doesn't allow any ESS larger than 80kWh at a residential property either from what I have read. - correct me if I am mistaken.

I've never put a vehicle, whether it be ICE (gasoline, diesel, LPG, NGV/CNG) or EV (BEV or hybrid) in a garage attached to my home, I'm certainly not starting now.

The same applies to my solar ESS, well away from the house in a reasonably fire-resistant home.

In all cases there's way too much energy in there just waiting to get out due to some failure or other.

I based what gets to stay inside my 2 car garage based on this scale from 1 being the most important reason :

1. How likely I will have to file an insurance claim with state farm (DO NOT want to have to file with them ever if I can help it)

2. How much pain would be involved with getting it repainted.

3. How new/nice the vehicle is.

4. How likely I will have to file a claim with geico. Not real hassle with them.

I don't have an ev so that hasn't been a concern yet.

Rest of my vehicles live under the different carports.
 
Ohhh this is soooo uncool.

Batteries are full, solars powering the house 100%. No place to put the power so the panels dropped way down.

Ive got to setup a dump load. I even have it running two old crypto miners I had left over. :(

Outside temps are 70 degrees to. If I turn on all the heat pumps to cooling the wife will kill me when she gets home.

I guess I need to wire up the hot water heater to it.

Yes, my question was rhetorical, I know there are EVs in Canada. It just seems a bit daft that stationary storage is treated so differently. Built to standards both are very safe. IOW why would one be more concerned about stationary home storage when there is no restriction on parking an EV in a building?

The funny thing with regulations here is the low quality bollards required in garages to supposedly protect stationary storage from your car/EV.

The power grid in PR is know to be a mess for years. The whole grid is down. Most people are too poor to have solar and batteries. The lucky ones will have a small generator.

understand that,

Anybody from Puerto Rico here to report on their situation?

but to be "Here" to report, they need some sort of electrical back up - and in-light of the recent 'Deye-Bricking-gate' I was pointing out that the only ones that "could be here" to report from PR would now need to be non-Deye inverter members...just to highlight what a crappy move Deye took, on those that have a tough enough time of things aready.

I assumed so,
I was away from the computer most of yesterday and didn't get a chance to respond until later - (I am on screen-time-limits these days !)
We see some of the regulations getting pushed by certain factions - ie fire safety but I feel the tech is moving faster than the regulators.
I hear that the Canadian Electrical Code will be moving to allow higher ESS and ease some of the requirements based on LFP chemistry - but so far that is looking like a 2026 code update - from what I am being told.
 
It was looking so good for today. Then the batteries filled up :(

11:30am or so it sunk like a rock when the batteries hit 100%.
 
Solar has been lame today in NE Ohio 7.2kWh, I got excited for a few minutes then the gloom clouds came back and spoiled my happiness ☹️ ☹️ :confused:
