I fretted for many months about installing home built Lifep04 batteries in my basement, on a rack next to a cement wall. Did my investigation of the risk and reached a conclusion. My conclusion is that as long as you connect them correctly and the device they are connected to is fused, or has a...

I thought long and hard about installing LifeP04 batteries next to a cement wall in my basement. I even had a discussion on the subject with the owner of the forum . Will stated that in his opinion, "if wired correctly a set of Lifep04 batteries on a shelf is about as dangerous as a stack of...

I have a 12KW PV (Iq7a inverters on each panel) system up and running ac coupled to a Sol-ark 15k on the gen port. If/when the grid goes down the system allows the PV to continue to operate, but it is very "flaky" and will turn itself off/on during the day with full sunshine and non full...

I experimented off grid with IQ7a inverters and the ieee2015 zero export grid profile. AC coupled to the solar 15K genpins. Goal was to have the enphase zero grid export profile control the iq7a's and ramp them up and down as needed to support battery charging and load. My findings are if the...

I am referring to "the company" that is selling batteries at the beginning of this thread. I am not trying to sell anyone here anything. Sheesh... the company I am referring to is https://www.18650batterystore.com/collections/lifepo4-prismatic-cells/products/eve-lf280k Which is what I...

Wow, I am impressed with the fast reply from Solark, On a Sunday no less. Here is the reply to my query on where to land the ground wire (that is attached to the ground mount array in back yard, 200 feet behind my home). I sent them the Enphase Combiner Box Schematic that clearly shows a ground...

Good afternoon I think I have a reasonable solution to operate with AC coupled PV off grid. I spent > 1 hour on the phone with Enphase Tech support this afternoon. They watched my system go from >9KWh to 300w several times while my main grid feed was disconnected for my experiment. They...

Hello Just to clarify the Sol-ark as currently connected does operate, the Wifi dongle is active, I can see the Load and Grid voltages if I drill down in the menus of the online connection software. There are no batteries, or solar currently connected, so I think the best description is it is in...

Hedges My understanding is it is a code requirement that the bonded ground is in the first grid connect box, whatever that happens to be. There are several other sources that appear to confirm this as code. Since I have an inspector who will check my install I don't feel like I have any choice...

Well.. I hate Will P. for posting this video. I was all convinced that I needed to spend the $300/KWH for EV4 rack batteries , especially since they are now fully UL approved and listed. He has all ready indicated that they are "taking over" the DIY battery arena, and for that low price, why...

Just curious what kind of results you achieved with AC coupled solar on the Gen port when off grid. What grid profile did you use, and what Enphase inverter model? With my 12kw array and Iq7a micro inverters gen connected, I was unable to get the Sol-ark to not export power , and if/when I...

Others recommend a seller fred480v on ebay. He sells 2 200w panels for $360 . Free shipping, I just received 2, work fine

Thanks you very much.. I will make use of them in my Sol-ark Setup screens. God bless and hold you. (No offense intended)

Hello I am using Unirac for mounting the panels on a 2 inch galvanized well pipe support structure that is inserted into 14 ground screws that are in the ground 5.5 feet each. The grounding layout/needs for the newest Enphase inverters is a source of confusion to me. They have 2 wires and are...

Hello ... I am in the process of completing my long journey of installing 30 panels with enphase Iq7A inverters, and have now completed the required installer training. Title is "Enphase Solar Installation training " . To double check my result, and confirm my ability to complete the full...

Will Sorry... I was mostly teasing you.. and I fully understand your reply.. and don't expect you to protect idiots who play with batteries from themselves. And in this field I am surely a rookie and sometimes an idiot. I spent several weeks reading and learning about LiFeP04 Batteries and...

Hello All... Thought I would share my learning, I have 12Kw of IQ7a inverters connected to the grid input pins on a 15K Sol-ark using the AC coupled feature. I also have 33KWH of batteries, and zero DC PV input. My goal prior to getting full approval from my Local Electric supplier, was to...

For what it is worth, I have a Pixel 5 running Android V13 and the app from the playstore installs and works on my phone. I had one loose bus bar on one cell, that caused that cell to go overvoltage, and charge stopped, addressed that issue, all cells now well matched, but the SOC for that...

I selected the 15k Sol-ark to allow direct feedthrough of my 200A main metered service. So the Grid feed enters the Sol-ark line input, the exits the Sol-Ark load directly to the 200A breaker on top of my one and only main panel. The entire home is running off that feed, so yes the Sol-ark has...

Hello Just to clarify, my question relates solely to an Enphase micro inverter array, that sends 240V AC up in home run feed to house. That home run appears to require 4 wires, L1, L2, Neutral and ground. I paid an online solar layout company for plans that meet code, and that is what the wire...

I have 30 iq7a enphase micro inverters up and running connected to my gen input pins on a 15K sol-ark each micro inverter is supposed to max out at around 350 watts. So my AC coupled install could feed as much as 12 KW to the solark with no issue. I have a battery attached that's 560 amp hours...

Ampster.. just to be clear , with the current "Off-Grid FW60 No Export" grid profile installed, and my 12Kw PV AC coupled only input, I have been charging batteries, and supporting loads for > 24 hours. My 30kWh battery bank was charged to around 93% when the sun went down last evening, and...

Good suggestions. I buried two expansion runs of 10 gauge UF wire in the trench. I have 14 extra ground screws free from unirac (long story). Next spring I need to get busy expanding with direct DC PV. I considered removing all of the expensive enphase inverters putting them on eBay and just...

Hedges... The plan is to follow the Schematic that Solark includes in the manual , fused disconnect switch first in line from meter to home, then the transfer switch (no fuse) then the 15K solark. Engineer 775 has shown this exact setup so I am pretty sure as long as the transfer switch is...

Hello I just got quotes from Amy, and all should know that there is a new VAT tax added, to your order, and that plus the normal Alibaba fee is about a 10% adder to whatever you buy. I just checked shipping to my address and these brand new cells from this company are cheaper then the price Amy...

Whine On ------------------------- I've sent emails telling the exact same guy something similar, he is just too dense to understand how I am using the Sol-ark. They also sent me approval for Level 1 operation 1 month ago, then said ooops.. Sorry, we sent you someone elses approval, you still...

Thanks closed loop makes perfect sense now. Wonder if anyone out there is working on JK BMS to Solark speak. Beyond my limited programming ability LoL. Thanks for the detailed reply. Once I get my two way meter installed I can use some of my excess PV to grid to grid top off after 3-4 days of...

Hello My current power feed is meter outside with no cutoff switch, then a direct feed from the meter box to my main 200A breaker box. You raise some good questions about what happens if/when the sol-ark craps out, I believe I have read that it includes a some kind of a passthrough...

Hello I am finishing up a 280Ah 12v build with a group 27 battery box. I would like to save some length and installl the 200A JBD BMS on the top of the cells. Two options, one build an inverted U shape with 1/4 G10-FR4 Fire resistant material, and attach the BMS to the "roof" of the inverted U...

How would PPL know you added the inverter if you installed it yourself? It is UL approved, and disconnects the solar from the grid whenever grid power goes down to protect the lineman working, what other risk is there I am missing? My local inspector told me as long as device is UL listed, I can...
