After a dismal failure on my first solar adventure, I am back in. About 2 years ago, I purchased a system, from a vendor online. Nice guy. Honest guy. he was just not particularly well informed on the equipment he was selling. Basically, he was selling china junk. I honestly don't think he...

So. I have my Sol-Ark 12k up and going for 4 days now. Of those 4 days, only 2 have been running loads. 2440w of panels on the roof. Day 1: install 12k and connect 4X trojan T-1275 batteries for 48v. let charge to 100%, no loads. day 2: connect single load circuit. circuit consists of: one...

We are planning for our system upgrade. Sol-Ark 12k has dual MPPT inputs. it can handle 6500w per input. if done in series only, it can go up to 500v input, but that would be without temperature correction, I assume. 12 panels X 41 VOC = 492v if panels get cold (it gets FREEZING here during...

I am very new to all of this, so forgive my ignorance. I am here to learn, and get more knowledgable about my system and solar and battery theory in general. During my research (I have been researching for around 2 years, on and off) I came to understand that your cells should be pretty uniform...

I have watched a few videos and read a few posts on this topic. first video I watched was looked to take place at a roadside market in India. a guy was fully disassembling 12v batteries, temoving lead plates, replacing what looked like cotton or paper pads between lead plates then reinstalling...

I will try to keep the update short, and instead focus on the new and moving forward: We (wife and i) bought a complete 2440 watt home system august 2020. it was nothing but one frustration and failure after another. short version: the person who sold it to us sold us low quality crap. It had...

As stated in the title. very few issues with the PV PRO app. Have used it for about 2 weeks. Today, the display of grid/battery/PV/load in the "power flow" section has stopped displaying the animation, and more importantly, it has stopped showing where power is coming from or going to. it...

I have an old hybrid controller, from some crap mfg, that never could perform as sold. it only puts out one leg of 110v... not a mistype. it puts out 110v. it also does not put out a true 60Htz, which made my clocks run slow. it was unable to absorb/bulk charge over 55.5v so when sun went...

As Stated In title. We moved about a year ago. we brought our entire system with us. previously it was installed in off-grid mode, so no need for the sensors. I honestly dont think they were included in my shipment. every single piece that remained after install (optional setup configurations...

first time checking water level. can I just shut off my battery breaker, while still leaving the unit on? do I need to totally shut off the unit to disconnect the breaker to the battery bank? is it safe to leave unit on, while still using PV, while battery is offline to check water level?

48v system. Sol-Ark 12k all-in-one 8,650w PV totally off-grid home. we are building a new home. will be off-grid. when we move, we will expand/upgrade our current system. current system is 2440w and supports about 40% of our home off-grid. currently, we use 300AH of FLA Trojan T-1275...

I purchased and installed my system november of 2021. that purchase was a sort of "starter" setup. charge controller/inverter, 2440w solar array, and 4 FLA Trojan batteries. we successfully filed and qualified for the rebate on all of the starter system. 26% of investment, credit offset on...

Wife and I are building a house, on newly purchased acreage. We will be living totally off grid. well, septic, wood fire heat and Sol-Ark 12k system. it gets hot enough in our area that air conditioning becomes a necessity during the peak of summer. in our current home, we already use solar...

EDITED TITLE: meant to post about battery balancer, NOT BMS. to clarify, in case I got my abbreviation wrong: 8 individual batteries total. 4 each in series, run in 2 parallel sets. they are Trojan 1275 batteries, 12v each. they have been in service for about 3 months. I am debating/shopping...

solar control unit is 5KW running 48VDC at 60A qcell 305w panels, wired series parallel 4&4. 8x 12v lead acid batteries, series parallel 4&4 for 48VDC. just made the switch to full solar last Sunday. The issue we are having is that we are losing power when early in the morning when we are just...

As I look to upgrade our system and move totally off grid, I quickly learned I will need to move away from FLA. This will be paired with a single Sol-Ark 12k unit. I am eyeing the Fortress eFlex. From what I have learned, the eFlex must first be installed as a set of 2 battery units. after the...

We are making the blueprints for our new homestead layout. this is for our new home construction, on new land. we will ground mount the PV array at the new house. how far away from the controller can we put them? stats: Sol-Ark 12k dual MPPT controller MPPT 1: 18 Mission solar 345w panels...

the home that we are building will be totally off grid. when we move, we will expand our PV to around 8,650w and our storage will be two fortress eFlex 5.4 while we do plan to expand even further, as time goes on, the above listed system should fully support our home. I figure something in the...

I've already contacted Sol-Ark. They are updating the firmware. I took some battery readings, and shared the info with them. My low battery alarm is set to 47.5v ShutDown voltage set to 46.0v Restart set to 52.0v moments before the shutdown, I just happened to look at my PV Pro app, and all...

I was sitting around thinking "you know, I don't have any constant, frustrating, inconveniences that I am forced to work around on a daily basis." Luckily the universe recently saw fit to gift to me a mint condition 2017 HP Stream laptop, in "1982 baby blue" with dual-core 1.6GHz processor...
