The Sol-ark 15k has a "UPS Time" setting for transfer to battery when grid goes down. The minimum is 4ms (any setting below 4ms is 4ms). Why would you want a longer transfer time? Minimize nuisance disconnects from grid in areas with dirty power? I could see a longer time that doesn't require...

Using the temperature gradient of the Oceans to make power. https://www.msn.com/en-us/weather/topstories/storm-resistant-tech-that-generates-electricity-using-seawater-tested/ar-BB1jm9pj Doesn't this hurt global warming because it will cause the oceans to heat up faster? Pumping the heat...

"A federal judge ruled Tuesday that a $1.7 trillion spending bill was unconstitutionally passed in December 2022 due to the lack of a quorum, " "Based on the Quorum Clause’s text, original public meaning, and historical practice, the Court concludes that the Quorum Clause bars the creation of a...

Not for DIY. This storage has potential. Note: only 40% efficient round trip. But for grid storage of excess renewable at a cheap price...

"A recent study conducted by scientists from the Department of Energy’s Argonne National Laboratory in Illinois and the National Renewable Energy Laboratory in Colorado found that solar farms don’t have to only harvest clean, renewable energy from the sun — they can also be breeding grounds for...

Instead of shoveling coal to heat your house, you can shovel salt. RESEARCHER DISCOVERS PROMISING NEW METHOD FOR DEALING WITH SUMMER HEAT: ‘IT’S A GREAT SOLUTION TO A MAJOR PROBLEM’ A breakthrough from the Eindhoven University of Technology in the Netherlands could help store sweltering heat...

I have an original Chargeverter in Connecticut. I have been thinking about switching to PlugOut for my Plan B. It has only been used to test it during the initial install. It has been eagerly awaiting use since then. I would part with it for the $400 it cost me, plus shipping to you. In person...

Doing a new roof, and have the choice of Asphalt Architectural Shingles or Metal roof. Any thoughts on Solar Panels over a Metal Roof (assuming the roofer and solar people coordinate)? Any other words of wisdom on considering a metal roof? Are they worth the additional cost?

A major U.S. power grid operator is warning that the upcoming closure of a Baltimore area coal plant threatens to decrease key electricity supplies across the mid-Atlantic region. | Fox Business...

I am looking for suggestions for a grid tied inverter: Limit export to 1,500 watts. Does not NEED a battery 120v preferred, but 240v OK. 1,500 watt is OK, but would like 3,000 watt that can limit to 1,500-1,800 watts. 48v capable. 300v min VOC preferred. Situation: Shed is fed by 15 amp 120v...

I wonder how much 4/0 Galvorn wire costs? Easily bendable? "... has the conductivity of copper, ..." https://www.msn.com/en-us/news/technology/scientists-discover-magical-material-that-s-stronger-than-steel-and-lighter-than-aluminum-and-its-potential-is-dizzying/ar-AA1c76lf

I have a new shed I can put a few panels. Unfortunately, there is only a 120v outlet within 10 feet I can connect to. Otherwise it is 50 ft to the house, and another 50 feet to the electrical panel. All the grid tied inverters I see are 240v. Anyone know of a UL listed 120v inverter at a...

I am having a gravel pad installed and shed dropped onto the pad. An outdoor receptical is about 10 feet away, and I plan to bury pvc conduit to the pad. Because the shed can go anywhere on the pad, I can't pre-bury the conduit and have it emerge at the shed. I'm thinking it is buried up to the...

Interesting CA Duck Curve. Power from Grid generation is actually 0 (lowest net power day in spring): https://www.eia.gov/todayinenergy/detail.php?id=56880 Forget NEM 3. CA should go to TOU. Pay you nothing for power between 8am-5pm, and lots for power between 6pm-9pm. Lots of incentive to...

I don't' think it is a good idea if you plan on having a swimming pool. I wonder what BMS you would use: https://www.msn.com/en-us/news/technology/electrified-cement-could-turn-the-foundations-of-buildings-into-giant-batteries/ar-AA1eFBIH

I have a Sol-ark 15k and am thinking about paralleling a second. It is relatively easy to parallel the load, battery, and Gen connections. The grid line is the difficult one. Any thoughts on what would happen if I skipped the grid line? One 15k can passthrough all the power. You can connect AC...

Summary: EndurEnergy seems like a great battery, but don't try to DIY. I can't get any info from Endurenergy. I can't imagine trying to install it myself without proper documentation. Ventilation requirements (battery or enclosure)? Can't get the wifi on the battery to work. Can't find a link to...

Space Based Solar: https://www.msn.com/en-us/news/technology/we-just-took-a-step-closer-to-beaming-limitless-energy-from-space-to-earth/ar-AA1cs2c3 Let's see, each satellite can produce 2 gigawatts, and requires a receiver on earth that is 3 sq miles (2 gigawats / 245w per m2). The USA grid has...

I have a new Sol-Ark 15k, and it seemed to randomly go off grid for a few minutes. I finally figured out it was because of L1 and L2 voltage changes. Normally, L1 and L2 track within 0.5v of each other, varying between 120.0-121.0v on average. When the inverter detaches from the grid, the...

Another thread got me thinking... the reason the Sol-Ark 15k is advertised as 12k off batteries is because it is limited to 275 amps off the battery, and they use a conservative 48v for the battery. Instead of 16 cells, if you put 18 cells in series, you can deliver 15k and stay within the 63v...

Your old batteries may be able to be rebuilt and be better than new batteries. https://www.msn.com/en-us/weather/topstories/new-study-makes-surprising-reveal-about-recycled-lithium-ion-batteries-this-is-increasingly-needed/ar-AA19B85u Don't know if DIY rebuilding will ever be possible.

Now that I have batteries, how tight should I set the Grid settings for when I transfer to batteries (disconnect from the grid)? Nominal 240v grid is supposed to be +/- 5.0%, or 228-252v Nominal 60.0hz grid. I think it is supposed to be +/- 0.5%, or 59.7-60.3 hz. I was thinking 227v - 253v...

I read about parallel batteries, and I am of the belief that it is ok to mix capacity with same voltage/chemistry. I have a Sol-Ark 15k with 6 new 5.12kWh Endurengery batteries (30.72kWh) in closed loop. I needed an "installed" system for the Energy Storage Solutions (f/k/a Connected...

I apologize if this has been discussed, but I couldn't easily find it. I have a new battery system of 6 Endurenergy ESP-5100. Is there a way to top balance them, or should I even bother? Batteries are currently at 53.2v (victron smartshunt). They were originally shipped around 52.5 volts, but...

The Sol-Ark 15k has two battery wire terminals. Each terminal is 160A, and combined the max is 275A. Question about running the DC wire in the trough. I thought I read somewhere that I should separate the wires (one torid on each), rather than bundling them together (two torids on the bundle)...

Sorry if I posted this in the wrong forum.... 40% increase in 7 years? I can't imagine the inflationary pressure on electricity. Not only do you need the generation, but you need a transmission and distribution grid to deliver it. Get your solar now to avoid the cost increase, and grid...

I'm thinking of how to parallel two Sol-ark 15k to increase grid down peak ability. In theory, putting the grid and load lines in parallel is not complex. However, in reviewing connection options, I couldn't find an easy way to connect three 4/0 wires together to handle the 200 amps from grid...

I have a new battery system, and am trying to estimate the "Active Dispatch" incentive payment for Connected Solutions or Energy Storage Solutions, particularly in Connecticut. The program is based on average kW delivered (not kWh) during events. It averages the events over the summer or winter...

My installer chose the Endurenergy ESP-5100 battery system. While it is sitting in my garage pending install, I am looking at one of the batteries. Anyone have experience with them? I can power it on (one unit, not connected to anything), and it produces 52.6 volts (run light on, fault light...

The rule is to have equal length paths (wire) when installing batteries. Two of the racks can be equidistant, but a 3rd rack is about 10 feet away from the others. Instead of installing extra wire, how about rotating the batteries between the racks once a year (also go from 2/0 to 4/0 for the...

As a backup to Sol-Ark 15k Solar/Battery, I bought a Chargeverter, and am now looking for a generator. For weight purposes, I decided to stay in the 4kW range, and dual fuel for ability to store propane for the rare events (keep a few 20# tanks). I was originally thinking the tri-fuel Firman...
