    How can I use Hyundai EV batteries for stationary use?

    I would think you could parlay enough cash in the auto-aftermarket to buy similar rack mount LifePO4's ready to go with a standard inverter.

    EG4 18Kpv fried PV input

    Sadly, it's not even economical. I think the idea was to make it faster, but any time you are screwing around with high wattage connections they really should have a screw lug. I didn't even find it faster since I couldn't figure out how the damn thing worked without scouring the web.

    NHX 10 vs EG4 18kpv Thoughts

    Likely smaller physically, but you have more wiring to deal with. You will need bus bars to interconnect the AC, multiple DC connections, though with potentially smaller wire.

    EG4 18Kpv fried PV input

    You could take this very screwdriver and cover it with heat-shrink if desired. After spending an inordinate amount of time with this silly connector, ... It pretty well shrouds the contacts, they are wayyy back there, I would verify no voltage to ground before you stuff anything in the hole...

    Safe cheap transfer switching with LVD in small system

    Buy TWO if it's important. Might be hard to find the form factor in a year if something goes south.

    EG4 18Kpv fried PV input

    I literally spent hours looking this up. I'd never seen this style connector. Place an appropriately sized screwdriver in the top I used a 10" bargain bin from Lowes. Stuff it in the hole as far as you can flat high. Note the flat part is not visible. Now peer in the hole and lift the...

    Poco says I didn't pay them?

    Straight-up: Putting the rails and panels on the roof was pretty trivial IMNSHO. I have a lot of them (32) but really nothing to it, a wrench and a portable drill, couple of J-boxes. Panels are only ~ 50lbs. Humping the effing inverter on the wall required assistance. Caveat: I have a...

    EG4 6000XP clicking

    @EG4_Jarrett or one of the other guys may be of some assistance. If the guess above is accurate, I think a firmware update is in order to throw a fault on a voltage mis-match.

    EG4 6000XP clicking

    There are no closeups on the display before you engage the breaker. As you engage the breaker we see the voltage dropping to 118 and back up to 162ish then down to 120. The High tension icon (gen?) appears to stabilize at ~123v when out of the loop. SWAG: The genny drags down the voltage...

    I could be way out in left field here, but do you have a 120v generator hooked to a 240v connection? Is that allowed?
  15. ksmithaz1

    EG4 6000XP clicking

    Where is the generator connected? To the generator input? Video seems to show grid power. Hard to have an opinion, need a wiring diagram. I thought the unit was 240v? Why is everything 120?

    Efficent microwave?

    Back to the OP: I guess the point is, it's probably not relevant unless you have a demand problem. It would be a lot MORE wasteful to trash a perfectly good microwave to save 50 watt hours (not kilowatt.... watt) a month. This is my problem with some of the energy saving people talk about...

    Efficent microwave?

    Oh c'mon. I use my microwave every night, it runs for at least 10 minutes a day on average. So for a 1500 watt draw we are talking 249 watt/hours per day, 7.5KWH per month. Thats going to really make a significant impact on my electric bill and/or solar storage if I can shave it down to 200...

    Efficent microwave?

    Something about the 18K umm PV comes to mind. A 500 Watt PC power supply will draw more than 500 watts if it is actually outputting 500 watts. Depends on the reference perspective and marketing. A vacuum cleaner with a 10A motor often doesn't have a motor that actually draws 10A. In the case...

    EG4 6000XP without battery

    No way around it with nowhere to get some electrons to make up any difference. Running an off-grid inverter without *some* battery is kind of odd. Things are going to turn off and on everytime the sun goes behind a cloud.

    how much inverting power would you need to run your whole house 100% of the time

    It's 240v for sure. Next time I'm in the office I'll hit up one of the engineering tech support folks to see what we have, not really my area. I logged into our customer web portal, but it's all around sales and ordering not documentation.

    My, my, all those people in the 19th century dropping like flies all over Texas. The undertaker would have been busy if he hadn't died from heat stroke. I hope this was a bit tongue in cheek. People today are so effing spoiled. Air conditioning for the masses has not been around that long in...

    Not with this box, it's just a priority switchbox designed to tap the Dryer plug in a garage so you can put an EVSE on the same circuit. I just re-purposed making my HWH the EVSE to control demand. I use an openEVSE that has a fully programmable EVSE unit with a bunch of API's for that...

    Disclaimer: I currently work for a Carrier distributor in IT. I read things and talk to sales droids so I happen to know about these units. It is without a doubt the best one on the market, at least, as long as you don't ask the Trane guys about theirs, or the ... :rolleyes: Every major...

    how much inverting power would you need to run your whole house 100% of the time

    You can get variable speed high efficiency central air compressors. There is a reason we got rid of window units and went to central air conditioning and heating in homes. A mini-split is more efficient, but it pigs up wall space, and doesn't vent into storage rooms and bathrooms and ...

    how much inverting power would you need to run your whole house 100% of the time

    Probably a bad idea, tank is too small, recovery time is too slow. While I really don't think an electric demand unit is a great idea with solar, you want it to heat back up fairly quickly. As the cold water pushes in the bottom of the tank more aggressive heating stretches the amount of...

    I doubt my grandfathers place used 150KWH/month. Just some lighting/outlets, a well pump, fridge. I think he had ~50A service, no AC.

    how much inverting power would you need to run your whole house 100% of the time

    Your sentence structure implies you mean KWH and not KW(peak). I use ~ 115KWH per day. I live in the burbs on 1/4+ acre lot. I've been on grid 8 hours one evening since February in an all-electric home. 210KWH/30 ~= 7KWH / day. Ten (10) 400W panels would handle it most of the time with a...

    Every body should start up with more fruit, bad idea to limit your intake of fruit everyone needs more fiber. (owwww) Not exactly. Single phase motors have a small extra "start" winding that tugs the rotor in the correct direction. It energizes via a capacitor which creates a phase shift of...

    The serialno is returned on each query. I haven't done a low level look at the data, but it puked easily when I first wrote the mess. I've been meaning to re-vamp. I don't care for python, the C libraries don't seem as stable. Considered writing the modbus stuff in a PHP library, the...
