I was seriously looking at a 48V RHINO for this reason, have wall space but not much "depth" so wanted something low profile-ish.

Yup! Thankfully no damage and everything still works as expected and at capacity.

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

After I posted brain clicked and went "maybe he's asking about adding more panels....". I blame the work week

You have 24 panels at 435 watts each, that's ~10.4kw assuming ideal conditions, to "use" the other 6kw of your inverters you need more panels. Unless I'm missing something in your post.

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...

Lookup john siegenthaler on youtube, he's been pushing low temp hydronics for a long time. I heated my house through winter with A2W heat pump with a max water temp of 101, at 32F I only need 97F water. This is for radiant in basement concrete slab and an air handler for the rest of the house...

Availability will be the question but if an OEM in China is making them it's only a matter of time for them to be available https://www.phnix-e.com/r290-greentherm-heat-pump.html

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

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

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

I was looking at the Big Battery Rhino for this reason, I have wall space but not much floor space so the less than 5 inch depth is intriguing. Price point is not as good though compared to this EG4 or the Ruixu wall mount units

Wills Video:

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...

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...

All accurate I'd say! For me though, I'm only planning on a single purchase of up to ~15kwh of battery, I have "ok" space for a rack mount but the wall mount keeps my floor more clear especially compare to most wall mounts. If the pricing was better the Big Battery 48V Rhino would be more...

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...

Lookup john siegenthaler, he's been pushing low temp hydronics for decades, lot of webinars on YouTube. You can go no buffer tank but the system needs to be sized exactly for the space with a J-Load calculation. I do not have a buffer tank for my setup, cooling or heating each zone allows for...

So I did get as far as getting a cooler, little controller for temp with a 20 watt heater and a "master" switch mounted to the outside. No loads other than the heater and the thing worked well, battery when I checked it has been full and the temp appears to have never dropped well below...

Uuuggghhhh, after a windstorm I now have L2 under producing, appears similar to an issue I had before with a loose/bad connection. I must not have zinched down the cabling enough and something moved. Update: Oops, I must have not had a panel torqued down enough somehow and it was half dangling...

Folks here suggested it as did the group I worked with where I purchased the hardware. The system is up and running, no issues, whether 100% right or wrong for the extra ground rod *shrug*

My ground mount with sol-ark 15k, I have ground from array to house plus a ground rod at the array, this was suggested by "everyone" (the ground rod at array). Check your AHJ and Utility for disconnect needs. My utility required one at the panel (even though my meter panel has a breaker inside...

I'd be interested in as well in hearing about this more if anyone has interacted with them before

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.

Got any favorite YT University pages you like? I'll browse the forums too

Looks nice! I have to many other "hobbies" that building my own isn't happening 😞

Oh yeah!

I'm in a rural township that is very "hands off", code guy didn't even care to see my inside work haha

Not wrong but I have no plans to move anyth in the utility room once it's mounted. Set it and forget is my goal 🤙

That youtube channel I sent earlier, they do a lot of paralleled 15ks. I don't know of a hybrid inverter that can do the amount of solar you have now in a split-phase setup, 3 phase there are units that could.

Right!? Long run must be worth it for them.... One idea is to build out a 2nd array setup that is programmed to charge batteries and use that stored power when the sun goes down. Leave the current array as it is. Other is to use existing solar array, replace the 4 inverters with something else...

I have a sol-ark 15k, my plan for batteries is for power outages but my understanding was that the scenario you lay out is what it can do. Charge the batteries with excess solar, once charged, export to the grid, once PV can't provide power you can tell it when/what to prioritize power wise...

Going through the debate of what battery style to get, timeframe is "summer". I have kwh to kwh net metering, the desire for the battery is to provide short-term power backup in the event of grid down situation versus banking power for use later. I can make the floor space for a rack mount setup...

I think this is something NY and utilities are going to need to look at as they push hard for "green" power. As you stated, 26kw DC array still doesn't cover your electric. I'm assuming your house is about as efficient as it can get to try and lower your usage. I read the below standard as 25kw...

I'm in upstate NY (south of SYR). Are you doing this a DIY system or going with a contractor and getting rebates? I'd have to research about any limits, how much power are you actually exporting versus producing and using on-site today?
