"
so it's not a knock to the install at all."
and again:
"not be able to grid tie them (again not a knock, "
You "back end" implied that my questioning of his price numbers, which I said seemed too low, had an associated quality issue, which in realty I NO WAY insinuated. So please, don't even pretend to slither out of you twice written KNOCK statements.
You made it perfectly clear before you used the word "knock", that you were totally fine with off-grid.
And I don't think saving money, in and of itself in a Capitalistic society would be thought bad of.
So ruling those two out, what was the "object of the knock"?
A verb needs a noun. What was it?
Perhaps your use of "knock" was a bad choice of words or that you are just too easily offended and thought your offering had to be pre-defended...
And one would hope, at least on this site, that EVERYONE wishes him the best, and if he can save money in the process, fantastic.

First off, I in NO WAY implied or even hinted that his install was somehow inferior. I merely pointed that the dollar numbers were way different than the current typical price out in the market regarding Li batteries.
Moving on from a comment that I should not have to be defending, if in fact the solid 3 fold increase over the batteries offered as a UL "construct" only is true (I have my doubts for a single vector explain), It would speak very badly for the state of affairs around such an old and well established certification.
I wish him nothing but the best with his new additions.
What are you talking about? What are you having to defend exactly? Who claimed his install was inferior?
I was simply pointing out in my own research I can easily find batteries much cheaper than the ones I installed, but I would not be able to grid tie them because they aren't UL Listed. I spent months trying to find an option that would save me money, and couldn't find one that had the UL certification, and I was very frustrated about it. I agree most list price on batteries are much higher than he just stated. That's it. Not a knock to anyone.
Pretty sure I was clear in the fact I would have done the exact same thing he did, use a less expensive battery if I wasn't grid tied and had to use UL listed. Not sure why you are so easily offended, but no one was attacking you. Not sure what exactly you are defending. I think its amazing he was able to 1 do it himself, and 2 save as much money as he did.

@william fitch
My assumption based on this price is that they are not UL listed, meaning would he attempt to grid connect a utility will not allow it. Being off grid, that's completely fine and I would do the exact same thing, so it's not a knock to the install at all. There's tons of lipo batteries you can get for super cheap, i've even seen them with built in inverters, but they are Chinese and are not UL listed so you would not be able to grid tie them (again not a knock, if I was fully off grid I would do the EXACT same thing).
I also use that exact same sol-ark inverter but ARK batteries. My batteries are 5k 100amp, $2600 each installed.

Hi: I took a close look at your price list. A point of note. Do I correctly read that you got 30 KWH's of Li batteries for $7500? That is about the same cost (Almost) that I just paid for my high end lead. In my research of Li battery pricing, well lets just say, it is unheard of. Li in every single case I have dug into, is always AT LEAST twice the cost of lead or MORE.
As an example, the SimpliPhi AmpliPHI LFP 3.8kWh 48 VDC battery retail on line is $3000 which would be $30,000 for 38 KWH's. These are often used with Sol-Ark. inverters.
Now if you said $7500 each for $22,500 tot for 30 KWH, I would have said that would have been a decent or more usual price.
In short the above example is $789 per KWH, me at $230 per KWH and you at $250 per KWH.
Now $22,500 for 30 KWH would have been $750 per KWH, a decent price.

30 Older panels 7500 watts = $3750, racking $1000, 12K Sol-Ark inverter $7000, 3 10KWH ATLAS LiFePo4 batteries $7500 .
Inverter output is 9000 watts continuous, so lets use that as the divisor to get cost per usable off-grid watt. 3750+ 1000+7000+7500 all / 9000 = $2.14/watt of useable 240VAC.
Keep in mind that this is with 30KWh of storage. Homeowner can add up to 3 more batteries as he sees fit to extend his storage capacity as he adds loads to his home by simply plugging them in parallel. The batteries include Anderson powerpole connectors on the bottom, and expansion is as simple as "plug and play". CANBUS comms to the inverter make it idiot proof.
No "labor" costs were included, since the homeowner provided the work crew (relatives, dad, wife, friends). If you wanted this done turnkey, I suspect it would be closer to 5 or 6 bucks/watt or more... DIY saves a lot of money...

If you don't mind, approx. TOTAL cost per Watt.

I installed my very first SOL-ARK OFF GRID system over the weekend. A sol-ark 12K. 3 strings of 10 panels and two 10KWh LiFePo4 batteries (owner will expand to 4 total as budget allows). VERY nicely designed system that includes CAN BUS BMS comms to the batteries. Hooked it up, turned it on, programmed a few battery parameters and IT RUNS PERFECTLY! When battery is charged, it curtails charging and powers the house as needed, up to 9KW continuous. BEAUTIFULLY DESIGNED GRAPHIC PANEL makes even a rookie understand EXACTLY WHAT IS HAPPENING IN THE SYSTEM! Highly recommend this for OFF GRID or GRID TIED – since it allows prioritizing what goes where and when in simple easy to follow menu screens. KUDOS to Sol Ark!!
