Hopefully it doesn't snow much. Need some dirt digging equipment to make some room for snow shedding

Here you go ?

Project is 95% there, passed electrical inspection (and final check by code) and need to have my utility approve my application to be able to export to the grid. Just got a "smart" meter so hoping that I can maintain the old net metering of 1:1kwh with a yearly true up.

Got the confirmation "ok" from my utility this morning to start back feeding! Semi-cloudy day so "only" produced 47.4kWh (meter says 34 pushed to the grid).

Wills Video:

Got lucky with mostly sunny today, 76.2 produced with a 16.3kw array. 9 hours, 7 minutes sunrise to sunset

Forgot the last two tie downs on my sinclair rack, don't remember how/why (other than being in a rush), more than a few wind storms everything was fine, finally after one winter time high wind storm (tho no snow...), noticed the following after seeing reduced power on one string

Just got the email this morning, a wall mount or floor mount (with wheels) Ruixu battery. 16kwh (314 Ah) self-heating with canbus and rs485 comms. https://www.ruixubattery.com/product-page/lithi2-14-3-battery-bank With early bird discount code plus shipping it is $206.19/kwh, lowest I've seen...

I went the backwards route with my design with the 15K. I moved my high loads to a separate panel that is upstream of the Sol-Ark, grid goes down, they go down, but my main panel on the house once I get batteries will remain powered.

Ground source in the northern states will always be an option if someone has the funding to do so. Air Source works well but the ground argument will always win since it's 50ish down there all the time. I went air source since the number of days where a air source heat pump wouldn't keep up are...

And throw in being on a ladder in the dark finishing up your panels with a head lamp only to look right and see two eye balls staring back at you from a hundred yards away

I was planning on waiting till summer to get a battery setup this size, but this price point has me questioning...

As a techy myself I'd be interested in being able to at least be given a stream of the data that I can direct to my own data collection.

My 15k shows DC Temp of -38.5C and AC Temp of 42C with 8amp of AC on L1&L2

Getting started

Not preferred but needed to do it...tree was shading one of the ground mounts, can tell when I the tree was removed...I knew shading was not good, but that level of reduction was not what I would have thought.

Mine is currently at ~15kw on the solar side and it says 142F in a 70F basement

That's personal! haha JK, actually I don't...I should take some, I do have some more wire clips to clean up the wiring a little bit more. Few more build pics here: https://diysolarforum.com/threads/16kw-dc-solar-with-sol-ark-15k.60384/page-2#post-950042

Heard back from a person I'm working with on this project. He concurs with needing to tap a grounding lug to one of the array posts, then "joining" those posts with #6 then tapping that into a ground rod at the array, also then coupling a #10 from the array to in house ground point.

Thought of that and it was discussed in planning, but having the gen ports available to accommodate a generator in the future was more favored.

Not using, but not long ago watched a youtube video about multi-zone units. Didn't realize that if the outdoor unit is running refrigerant is running to all the indoor units irregardless if they're calling for anything or not. It's also possible to end up with a split demand "issue" where one...

Not home so cannot confirm but based on the weather at work it is clear blue sunny winter sky and 16F. Looking at the input of the sol-ark I have quite the imbalance on the MPPTs. The only reason I can think of for L1 being so low is that the uphill side of the array, the panel is "close" to the...

Depending on the setup his statement is accurate. In short though like the others mentioned, the Sol-Ark will not export any power via the "Grid" connection if the grid is down.

I do keep forgetting about that feature. A minor but important detail is joining the two together...good reminder!

I'd be putting this in my unfinished basement space, so the wall it's going on would be fresh built with the need to hold a lot of weight taken into account. Also temperature won't be an issue since it is a conditioned space.

Yeah not sure how I feel about relays. Interesting about RT Breakers but I agree the manual turn on is annoying...maybe I'm best installing as expected and wait for sol-arks critical loads panel to come out, reads like it'll have some kind of load shedding capability.

My brother expressed this too, but he also uses a combo of heat pump and boiler. For John I can't recall an exact video for in-slab and fan coil using the same temp water, he does highlight the design of staple up radiant like you mentioned. The webinars are so long that I'm not going to go...

Given the early adopter discount bringing the cost per kwh way down, it's tempting...have until April 30th to get it at that price, bigger question is to wait for your video or take the "risk" and just get it...

These types of mini-splits have been out for a while, this is the first company/distributor I came across a while ago (well before EG4 advertised them) offering these systems: https://www.hotspotenergy.com/

Learned that one the fun way...metal shaft screwdriver with plastic handle, tightening down the PV wires from the inverter at the disconnect located at the array, finger slipped and touched the shaft ⚡⚡quite the tingle. Went inside, grabbed another beverage and threw the DC disconnect at the...
