    Yes, those I do like. Construction guys like the cheapo push-ins because they're fast. Ive replaced most of the originals in our house due to being loose and sketchy. A few left that are behind furniture I haven't moved yet.
  • Post in thread: 30 Percent Tax Credit ?

    Except most of the demand is not at night (when the solar is useless anyway). It isn't going to help going "green."
  • Post in thread: Generic Jiangsu Solarman 600w Panels $130 on Amazon

    Attempting to destroy US made competition.
  • Post in thread: Assuming you pay $0.12/KWh, can you ever come out ahead going full offgrid?

    That's probably the generation charge. There is then the transmission charge, then yeah the taxes and fees. Ours is 10.9 cents for generation and something like 5 for transmission. Wasn't that long ago our generation charge was half that.
  • Post in thread: 240v well pump -> offgrid

    Test a few times - it may (likely) not have captured it.
  • Post in thread: Prepping for impending grid outage

    Lol...wow. I don't even know where to begin.
  • Post in thread: Relay advice for switching off 12v loads when AC loads are disabled by inverter

    Why not add an outlet that ties to an existing circuit?
  • Post in thread: NEC 2020 PV Rules

    Probably is. Probably was written by a set of beurocrats who have nothing better to do.
  • Post in thread: House burned down

    BUT 3V difference isn't going to sustain an arc across the the fuse. Even if you were dumping 500A, that's still only at 3V and the mega should never have a problem breaking that at only a 3V potential difference.
  • Post in thread: Home fuse box vs breaker box.

    They did do that - different size bases to prevent a 30A from screwing into a 15A socket for example - but they are not resistant to the wad of foil or other such measures. Plus you can fit more breakers in the same space. And breakers can be reset. And for AC stuff, breakers are plenty fast.
  • Post in thread: Are we all getting GRADE B cells??

    So If you shouldn't top balance (which goes against what everyone has been saying and doing to fix imbalanced pack problems) - what SHOULD you do?
  • Post in thread: EG4 18KPV - What not to do in parallel

    I'm guessing (again, GUESSING), that the reason this happened was the crossover cable created some sort of communication havoc that broke the logic, somehow. Hey, wanna run another test? Pull the cable entirely, power it all on, see if they operate, and then see what happens when you pull the...
  • Post in thread: Battery cable size

    Depends on how much current you're drawing.
  • Post in thread: EVE LF280K welded studs flying off like a bunch of acrobats in a circus

    Maybe low speed/performance small vehicles and paralleled cell banks.
  • Post in thread: Outback Radian GS8048A in AC coupling mode - max GDI question

    So I'm more heavily leaning toward the Radian now because 1) it is available now and 2) it may provide more long term flexibility. Sure, the updated, evidently more intuitive interface of the Mojave would be nice, but I can work around it. Out of the box support for my array would be great too...
  • Post in thread: Solar has been hijacked/co opted. A wakeup?

    Of course. Make more money! At our expense...
  • Post in thread: Looking for 48v dc light switch

    Um... Larger? Relatively, I guess yeah. Heavy and pricey? How about less than $1 and weighs maybe an ounce?
  • Post in thread: LIFEPO4 Smoke and Fire Dept

    I'm no pro, but I'd use it while keeping a stink eye on it for a while. Could either replace the burnt cell or reconfig to 15s, I suppose.
  • Post in thread: Poll: How was your experience with signature solar?

    Well that's the problem, no one can really verify that.
  • Post in thread: 2 x in 1 box LifePO4 15S build with JK-B2A24S20P BMSs

    Are they 15s or 16s? Can't mix them.
  • Post in thread: Looking for 48v dc light switch

    I like 3000k-3500k for many living spaces. A little less yellow than incandescent 2700k but not blue. The 4500-6000k range for bath, garage, basement, etc.
  • Post in thread: Covering exposed metal (e.g., inverter studs)

    Messy wad of electrical tape. I've used a piece of a milk jug cut and taped to shape as well to cover up things for a temporary barrier.
  • Post in thread: Signature Solar Tech Support...Ghosting?

    I hate having unread emails staring at me, so they all get "read" - now whether I fully read them and remember or understand them is another matter o_O
  • Post in thread: 280Ah Battery, Just Beginning

    I'm just building my battery. I just got one set of 16 cells top balanced. Going to reposition them into parallel, snug the fixture (just a 2x8 layout with 6 threaded rods and plywood end plates and bottom). Done. I'm not screwing around with measuring pressure but I don't want them sitting...
  • Post in thread: how long until DIY solar is dead? -- states are beginning to require microinverters

    Look in the manual how to set up AC coupling. It requires the micros to support frequency watts control also. In my case, I have to configure them to support it. Chilicon has the instructions how to do it on their micros right on their website.
  • Post in thread: custom made battery box for eve LF280K cells

    I'm just gonna use a cheap junk tablet with spoofed GPS location somewhere in Uzbekistan.
  • Post in thread: can this breaker be used as a double pole disoconnect

    I think you're mixing up your volts and amps on the ratings of the breaker. You're right, wiring two 150A breakers in series won't make them handle 300A. It won't. But we're talking about the voltage rating not the amperage rating. Wiring the two breakers in series with the handles tied together...
  • Post in thread: Flying under the Radar!

    Safest way is to put stuff in "off grid" - move what you want to a separate sub panel fed by an off-grid inverter that cannot backfeed the main panel. Run AC from your main panel to your AC-in on the offgrid inverter to run stuff from grid power when there isn't solar/battery to handle the...
  • Post in thread: Is Outback Energy closing up?

    Urgh do I burn more $ on another Radian while I still can. Not that I Need it, but I want it.
  • Post in thread: Micro Inverters ???

    I don't think my Chilicon micros need the gateway to function, but I am not sure if they can be initially set up without it.
