    When using a EG4 6000XP with grid assist, would that be considered grid tied and i have to deal with all the utility provider interconnect nonsense?

    Because the OP wants to use a 240v/25A non-grid tied inverter. Then he mentioned 50A would be good, and Emporia as a reference for his demand needs. I don't know a thing about the product, but if you expect to run your house from an inverter, it needs to be sized for your demand not your...

    When using a EG4 6000XP with grid assist, would that be considered grid tied and i have to deal with all the utility provider interconnect nonsense?

    You keep saying zero "export" which implies it ties to the grid. The 18Kpv can tie to the grid and set "zero-export". The 6000XP is incapable of grid-export, it allows grid backup for the solar/inverter. A subtle difference. If you truly don't need more than 25A of peak demand on any one leg...

    None the less, the problem is always DEMAND, and the 6000XP is not 50A, it's 25A@240V. You need to track peak demand to determine your needs.

    EG4 18K - Air Conditioning won’t run without grid

    A normal "soft-start" is an extra capacitor that is connected to the motor to provide more current to the start winding in the motor during the initial start, that is removed once the unit starts to keep from burning up the winding. Staring current is only reduced nominally. MicroAir actually...

    When using a EG4 6000XP with grid assist, would that be considered grid tied and i have to deal with all the utility provider interconnect nonsense?

    6KW = 240v@25A This is a split-phase 240v inverter. 25A not 50. Technically you could pull 50A at 120v assuming you could perfectly evenly distribute the loads on each phase, but you cannot pull more than about 30A on any one leg, not even that for any length of time. Internally you have...

    House burned down

    We are talking about burning a house down. I would say propane storage would be relevant. Might not be a great idea to put a 200gal tank next to your solar battery bank. YMMV.

    Time Jumping on EG4 18kPV

    Got a logfile? Is the unit online or fully isolated?

    When using a EG4 6000XP with grid assist, would that be considered grid tied and i have to deal with all the utility provider interconnect nonsense?

    Correct. The 6000XP does not have any "assist" function and does not "tie" directly to the grid AFAIK. It's an inverter with a built-in transfer switch. This makes for a very simple interconnect to a smallish "critical loads" or "solar output" panel with grid backup. OTOH I'd probably just go...

    When using a EG4 6000XP with grid assist, would that be considered grid tied and i have to deal with all the utility provider interconnect nonsense?

    But I'd put a separate 150-200A ATS with the inverter as primary in front of the panel. Easier to visibly see how it's wired and working to any inspector, no need to break out any manuals to explain. Something like this: https://www.amazon.com/dp/B07SSB956Z

    When using a EG4 6000XP with grid assist, would that be considered grid tied and i have to deal with all the utility provider interconnect nonsense?

    Someone correct me if I am wrong. I believe it's just an inverter with a built-in transfer switch. The "assist" is it pops the DPDT relay and sends the load over to the grid lugs instead of the inverter output.

    4 X class solar flares to impact this weekend.

    My daughter closed the door on my son's finger once in addition to my own foibles. The edge of the door panels have a modicum of give and there is a gap which should prevent chopping off a finger. It disgusts me to see people using these kinds of things to bash manufacturing. Any machine can...

    Really? The man who built the company and sits on the board, has ZERO input on safety? Interesting. Must be because that *sshole must just want to kill people? My finger has been closed in a car door more than once. Once as a child. I have done it myself in a regular car. This is a classic...

    95% savings on electric bill with solar (and some help)

    No net-metering for me, I just pay the $20+/mo. Your power must be really expensive. I'm around 3MW in June/July, highest bill was a little bit over $400 in years past. Cut that down dramatically last year, with the first full month on my August bill (7/15-8/15). I doubled my batteries in...

    Oops, already did that 20 min ago, no gas station in site! To my point, gravity feed on a bike changes the paradigm. Pushed that B about 3 miles. Agree. None the less, testing/ratings should be based on 100-0-100, whatever those numbers might actually indicate on the battery in question is...

    Email? Don't you mean the carrier pigeon that will get released by de-activating the magnetic latch on the spring loaded cage door when the power fails?

    No magic smoke, but no $ savings because I played with AC charging.

    That is incorrect. By DEFINITION 1 FULL cycle is when you discharge from 100 to 0 and back to 100. 100 to 50 to 100 to 50 to 100 is two HALF cycles. You can not make the assumption that the "wear and tear" on the overall component / chemistry is the same no matter how you treat it. This...

    I keep forgetting about this. Probably why nobody will fly on his rockets/transport missions up to resupply and rotate crew for the ISS. I for one would much prefer to fly on a Russian rocket and come down in a tiny capsule than hop into one of those SpaceX death traps where nobody thought...

    4 X class solar flares to impact this weekend.

    We are just doing pure speculation of course. In that light, I submit, drag is a function of the density of the medium, and the footprint + mass of what you are dragging thru the medium. I'd say Tesla/Musk/et al has a bit of experience in that department. Assuming the LEO devices are fairly...

    Concern regarding unplugging MC4 Connector

    You should really have a disconnect inline on the string. I use DC breakers, and flip them off any time I'm messing with my "shuffle-panels", but if the circuit is broken end-to-end there should be no flow in-series. Electricity is fickle stuff sometimes, but must have a path to a load to pull...

    4 X class solar flares to impact this weekend.

    Two ways to do it. Assume it's going to puke, and have the ability to re-launch an adequate number of replacements (make them disposable) or spend a gazillion on drastically more robust hardware that may weather the storm. . . I guess we shall see.

    4 X class solar flares to impact this weekend.

    To the point of this article, this affected LEO satellites that were being launched, failing to get to the right spot. I poked around, wondering about real effects. Starlink could be screwed.

    Luyuan battery case

    Ground is whatever is the most dense mass the potential can hit. A radio works in a car because the antenna uses the chassis as a "Ground" for the radio signal induced current in the aerial. There should only be one point of connection between all earth grounds (rods) and all "grounded" metal...

    Meh, satellites, How much "increased drag" for something floating around in space? Not buying this is going to do anything significant to the devices unless it just fries it. The thing is the event is significant because a magnetic pulse is inducing a current on the wires. If you have 5 miles...

    EG4 18K Is Only Powering Loads in EPS Mode

    If you have a traditional 'soft-start' kit remove it and get the Micro Air EZ Start: https://www.amazon.com/EasyStart-Commercial-ASY-368-X48-Conditioner-Conditioners/dp/B083H64Q5P It makes a huge difference.

    Is there a better MC4 tool?

    It helps to clean and slide the locking tabs. I sprayed it in the plastic sockets last go around, and cut the locking tabs off with a razor knife last go-round on several of the old connectors. Drives me nuts, I considered cutting the things off and wire nutting them with a baggie and a tie...

    Is there a better MC4 tool?

    MC4 connectors are bloody awful IMNSHO. I've found one problem is that the plastic pins like to sieze up a little in the receptacle, then dust and dirt get behind the locaking tabs just enough. I had a couple actually break off after I cut the locking tabs trying to wiggle them free. I think...

    The next thing? Inverter or Battery? All in 1?

    A standard duplex/multiplex connector and smart bus for solar panels. Daisy chaining panels should plug A-B-C-...-AIO, the electronics in the box could have a protocol to reconfigure the parallel/serial chaining as desired / optimized, and handle any RSD requirements. The box on the panel...

    Heat Pump water Heaters

    The copper hot water pipe under my slab started leaking. Copper corrodes though it was 50+ years old. I've had a couple of three water tanks crack and leak. One destroyed a wall. I'm skeptical, but perhaps it's softer/more elastic/thicker?

    New 10kw NHX AIO From Watts247

    Oh good grief. I've made a number of firmware suggestions to the EG4 team, several have been implemented over time, likely others have made similar ones, and I'm sure they've "stolen" ideas where other systems implement edge case issues in a more perfunctory manner. Products like these must...
