After discussssing with city months ago, they said the huge cottonwood tree was on my property, not city land. So I had everything arranged to cut it down, now I get letter saying it is on public right-away. It is healthy and I can’t touch it. With that tree, I don’t think solar makes sense...

The heck with solar, this should solve my energy needs. At O’Reilly Auto Parts. Go to https://www.oreillyauto.com and search for 121G.

I read other threads that say Hithium is rather scammy. But the company looks legit in building large power systems. This battery brand was previously one of the factories that produced batteries for CATL. https://hithium.com/en/product/cells-modules Anyhoo, I have not bought these, but got...

Sorry, but I did a search and I can’t find that video of a guy in North Dakota that installed a whole house heat pump furnace in North Dakota. I think it was a Carrier brand. Anyone know which video I’m talking about? Thanks.

$1900 each + shipping (-$100). Can parallel up to 16 units. Three available. PM if interested.

What is an “AHJ?”

Sol-Ark had internal breakers on the battery terminals for just the positive. I have inverters without internal breakers. So looking to add external breakers. (I already have T Class fuses that I will also be using) I was speaking with a manufacture of batteries, and they sent me this...

Any leads where to pick up a 48 volt lamp? I was thinking of having a couple handy in my utility room in case I ever have to shutdown system and do some work. A fixture I could just connect to one of my 48 volt batteries.

If you were building an off-grid ~2000sq. one story/level home in northern Arkansas climate, what type of HVAC system would you use with solar? In floor radiant heating? Geothermal? Mini splits? Etc.

I am buying these for my Sol-Ark 15k, but I’m not familiar with wiring (first solar project). They sell two versions: Enteligent NMax RSD + Optimization M900A1-M4 (Staubli MC4 connector) Enteligent NMax RSD + Optimizer M900A1-S4 (BizLink S418 connector MC4-compatible) Any guidance on the type...

I will have too many panels for the Sol-Ark 15K, but instead of the expense of adding another 15K, what are the thoughts about a MPPT charge controller? So the 15K plus the MPPT charge controller on the same busbar to charge the batteries in a open loop system. Sol-Ark representative that I...

Would getting a building permit for building a ground solar array even be possible for someone in a large city neighborhood? Need neighbor’s approval?

For the positive and negative battery busbars connecting to the rack batteries, is there a minimum distance between them?

$1820 before shipping. I don’t need California approval, but if anybody does thought I’d pass this along.

Anyone know of sources for larger panels that won’t break the bank? Used ok too.

Would like to increase battery bank. But not in a hurry as a project for the batteries is at least a year away. What do People think about buying them now anyway? The price seems like it’s in a sweet spot currently. Concerned about the economy going forward and future trade relations with...

JA 410: 0.099usd/watt ($40.59) 36 in a pallet. I’d imagine closer to $0.20W with shipping if you bought a couple of pallets...

I have very limited wall space for my inverters, ATS and existing main panel. So, I want my ATS to butt up next to my main panel. Near zero clearance, maybe 1/4” Inverters will have the required clearances from the manual. Any problems with doing that?

Is the Lynx Distributor listed? And if not, is there a fused alternative that is? Preferably UL listed.

Just looking at wire troughs, they seem expensive. Are people making their own? Is wood a bad idea? Wanting one 6’ wide and 12” deep.

Anyone heard of Lide BMS? Reviews?

OK, I have had a few installers look at my flat roof. I’m at 45N 93W in Twin Cities, MN. One said they found 12 degrees to be the best overall, another one said 35 degrees. Steeper is obviously better for snow consideration and power generation in winter. The biggest downside seems to be the...
