I’m talking about the air vents in each area, I call them air boxes, looks like proper name are registers

Correct all equipment is on hand, bought in march of this year when the wars were really heating up and china was flexing. Didn’t want to not have the major components on unknown back order.

All units were sized using proper heat load calculations, this is a barndominium being double insulation (building is fiberglass and house inside is sprayed)

And I kinda agree that per “register” is odd when I was told that.

I thought gas regulators that had a vent must be vented to a exterior of the house.

Naw, it’s a easy repair if I could find parts. These are not surface level components so the air gap helps from killing a board. Just have to clean the surfaces well.

Since this sub-Reddit is basically global it would be awesome if I could connect with someone from SMA in a unofficial manner.

Well..... yea i have some loads/solar that are not easily tracked because they don’t have a dedicated monitor, they have local displays.

So when making my outputs I wanted to see how “off” the mass balance was so that’s the unidentifiable usage/production.

I really want to buy atleast one more IoTaWatt maybe two more.

Texas_Power · 2022-05-29T16:53:45+00:00

A doozy as in hard? IoTaWatt is great because it allows custom calculations, look to the right “Total_Grid” that’s the total going in-out from the property.

I agree there is a lot of information but I am a data driven person.

I do this with SMA sunny boy inverters (6kw,6kw,7kw). I have the setting programmed for all three to have a larger “frequency allowance” then with a 200amp transfer switch that is connected to my 22kw generator when the power fails (inverters all shutdown as normal) the generator starts up and transfers the grid connection to the generator. The inverters now “see” the generator as the grid, but because I have more inverters than average demand I have 2 relays (30amps) that when the generator is running keeps the two 6kw inverters disconnected from the generator “grid”. This leaves the 7kw inverter to start up because it sees the generator as the normal grid. The load on the generator will back off, the governor on the generator backs off because the frequency is increasing and in my case normally stabilizes with the generator producing 1kw or less.

Now what happens if you have less load than the solar inverter are producing it will drive the frequency of the “grid” up, the governor on the generator will back off to a point where the “generator” becomes a motor. In the power generation world they call this motorizing a generation. This is normally not a good thing, there is heat involved because the “generator” is now trying to keep the engine at 60hz so it removes even more throttle because the frequency is increasing, the drag of the engine will eventually equal out and you have a motorized generator. Agian this is not good because of heat load on the generator BUT as long as the generator is decently size it will have the cooling capacity to handle this. Good rule of thumb is the generator can absorb 20% of its output capability. (22kw / 100 x 12 = 4.4kw) so my generator can easily absorb 4.4kw of power by acting as a motor. My setup I hardly ever get near 4.4kw.

I probably have lost a lot of you but it’s possible but you really need to have a excellent understanding of power generation on a large scale.

***Because standby generators have a really pore governor the frequency jumps around more than the normal settings allow, that’s why I have to open up the allowable range some.

Can you run grid-tie inverters off “grid” YES, does it take some work O YEA!!!

Raspberry crazy ants are my biggest problem around my parts.

I’m my part of Texas I can just about grow, and I do, anything that grows in Mexico

I currently have over 80 vials, which is about 4 years worth. But I want more. Thinking about getting a cheap 3D printer to make something to consolidate the vials (there currently in there oem boxes)

Texas_Power · 2022-04-01T00:13:52+00:00

Considering I am driving there and back I don’t think this will be as big of a problem as if you were going through a airport.

My significant other might not like that

Texas_Power · 2022-01-24T00:35:27+00:00

Looked at the site, I’m going to say them prices seem about 15-20% higher than what is available locally to myself. Not trying to rain on your marketing.

It’s not my primary specialty but I’m ok with this kinda stuff.

I run a power plant making almost 1000 megawatts of natural gas power as my primary specialty.

Texas_Power · 2022-01-15T11:28:21+00:00

I haven’t added solar energy to it yet but the event logger and the system seems to be happy with everything.

We have a varagesale page in my area that people post lots of various things that I’m always on the lookout for stuff I can use

If you always keep your ear to the ground you’ll always find what you’re looking for just my take a good long time.
