  • Post in thread: State Farm insurance offering Ting electrical monitor

    It is interesting, but for these reasons, not useful for me: - clown, er ... cloud-based. needs wifi/internet, transfers data to others - insurance ... do you really want your insurance company to know things to this level? - subscription-based (after 1st year, if not covered by insurance) ... I...
  • Post in thread: Be wary of SOK

    I still think SOK makes the best "infinitely repairable" battery out there ... I can't imagine a scenario where something can't be fixed yourself. Given the weights of batteries/assemblies these days, I am starting to think that warrany "swaps" are out of the question if going above 12v sizes...
  • Post in thread: 4 12v batteries in series, did I screw up?

    I agree you want a 48v *battery bank* to go with your 48v inverter/system. How you choose to implement that battery bank, whether as 1 battery or many, is up to you and your (fallback) requirements. A single 48v rack-mount battery has always seemed iffy to me ... I'd have to have two at least...
  • Post in thread: DIY off-grid solar system with the grid backup

    I'd invest a wee bit of time in the design (calc) stage ... verify on paper that everything will do what you want. All too common mistakes are guesstimates, buying first then planning, designing while assembling, and so on ... get the design done on paper, and verify that everything should work...
  • Post in thread: Quietest Set-And-Forget Off Grid System For A Few Lights, TV and Internet.

    I would say get a solar generator system (these are everywhere on Amazon and elsewhere). If anyone (you) has some diy skills, build a solar generator yourself to save money ... youtube videos abound. If nobody does, and you don't want to take on the task, then have them buy a solar generator...
  • Post in thread: Off grid new build home

    Our utility shed 8'x16', heated thru winter, houses water (tanks, pumps) and solar gear ... no concerns; I don't have a system that could blow out and spray water in every direction. If you do anticipate this, just work on separation methods within the shed ... occasional spills/flooding would...
  • Post in thread: My Solar PV journey is officially ending

    You've been extremely lucky, if: - a street transformer never blew - trees/branches/ice never took out a line - cars didn't crash into a pole - weather events (tornados, hurricanes, deep freezes, heat waves, etc) didn't affect some or all of the overall system ... such that it didn't affect...
  • Post in thread: LVGOO 100ah 48v Server Rack Batteries

    From what I can tell on their website: - no support ... no way to figure out support, no forums, nothing ... you will be on your own after buying them - user guide ... seems to be the datasheet, meaning no real user guide; warranty document mia - a fire extinguisher, built-in to the unit? The...
  • Post in thread: What would a standard for plugging solar panels directly into our homes look like?

    Can't "plug a generator" into the home, w/o pulling a permit, getting an electrician involved, etc. Those with no experience (and little common sense) get killed all the time, or backfeed the grid, etc. You *can* buy a generator, and use it as an appliance, where you only stretch extension...
  • Post in thread: Just tired of companies that sell solar products

    Don't know all the vendors on your short list, or what problems you are having with each, but I know what to expect from them ... nothing. Seriously, become self-supporting (which is what it sounds like you are doing), and don't expect anything from these *sales* organizations, other than...
  • Post in thread: Selecting a generator for off grid solar backup

    You'll want generators with "auto-start" capability, and it sounds like your inverter already has the inverter-side auto-start functionality. Sites like this one might help with the research for you: generatorbible.com To quote one of the many inverter pages/manuals describing the...
  • Post in thread: Newbies in this field of solar, read it before you even start a new solar project.

    I built my system from components ... not knowing anything, other than I couldn't have and didn't want a grid connection where I was. I did a bunch of research. Started out with a Magnum 4024 (tier-1, LF), and RTFM'd more than a few manuals, but we got it done. The complete system...
  • Post in thread: 48v or 12v.. + solar/battery combo for most things.. which way to go?

    As you are currently grid-connected, totally agree with the above "reduce existing loads by all conservation measures". With that done, next might be to determine your electricity costs/times ... does your utility charge more for peak hours, and less in off-peak hours? If so ... If you are...
  • Post in thread: Nature’s Solar Generator - What do you think?

    All SoGens (good acro, btw) have "sex appeal", and adding wheels is even sexier ... however, these are what I consider to be the numerous "strikes" against this particular unit, at this time: 1. AGM instead of LFP ... that sounds like the product was rushed to market, and at the very least...
  • Post in thread: What would a standard for plugging solar panels directly into our homes look like?

    There are still a few islands of "do your own thing", wrt building codes ... except for individual reports like yours in a few spots across the states, these appear to be reducing down. I still contend that you have to "do your own thing" correctly, as in, if you mistakenly backfed the grid...
  • Post in thread: How can you ship LFP Returns since they're HAZMAT

    I had purchased an AmpereTime battery that was bought in the US and shipped to me by UPS. It's a *sealed* battery (no visible seams), and had a bad BMS; AT gen'd the shipping label for me, and UPS picked it up and shipped it back to the vendor in the US ... nobody had any concerns. This is not...
  • Post in thread: Advice for Signature Solar

    I had to buy an HF inverter for a project, and I skipped SS because I saw zero website self-support mechanisms. I don't need to call in (I dislike waiting on the phone, and detest 1st-level phone support), and a "form submission" for support is a black hole, but a few basics (SS product forums...
  • Post in thread: Trend toward bigger panels

    Hmmm ... recently went w/ Renogy (8' x 4') 550w panels, as just 4 of them (2s2p) max out my midnite solar classic 150 *and* they are the basis of a full (south-facing) carport, right next to the utility shed holding all the solar gear. These replace some 265w panels (5' x 3') that cantilevered...
  • Post in thread: Generators for charging battery banks.

    I'm a little late to this party, but on our rural homestead, we use open-frame gennys for backup power, when weather or extended usage precludes solar. With a magnum 4024 inverter/charger, we pump the open-frame genny power into the inverter, and it charges the batteries just fine; it also...
  • Post in thread: My Solar PV journey is officially ending

    For folks that are on grid ... a "backup" system seems of high(er) importance. No matter where I lived in TX, CO ... outages happened, and for the strangest reasons. These range from brownouts & other fluctuations to full blackouts. A small parallel inverter/battery-bank/panel-less system w/...
  • Post in thread: Why Hasn't Aolithium Gotten More Attention?

    The devil is in the details, so really ... buyer-beware. You'll have to spend hours poring through the specs for the battery from a vendor plus review tear-downs to check for construction and components and their BMS choice, all of which goes into how you'll use them (configuration rules from...
  • Post in thread: Adding a generator. Is bigger better?

    We utilize Westinghouse wgen9500df (propane) open-frame gens ... their main purpose is to recharge battery bank when solar isn't cooperating. This is pretty much their only function, so it is a nice, smooth load for the gen. At most, 4 hours per day. This model line-up typically has electric...
  • Post in thread: Building a 24 V battery bank: Using 12V batteries is much cheaper, but is it worth it over using 24V batteries?

    Some reasons for building a 24v or 48v "battery-bank" out of 12vXXXah batteries, especially where the battery vendor supports such configurations: 1. quick reconfiguration if a single battery gives grief (even temporary). the more batteries in the battery bank, the better the chance to...
  • Post in thread: 3000sf House Off Grid Sol-Ark/EG4 build with "Power Shed"

    Excellent! Nice system, design, and ongoing construction! This is, by far, the cleanest construction site I've ever seen. Love the "shed"! I was in same situation in Colorado ... $30k for 10 poles to bring power to house location, so we just went off-grid ... built an 8 x 16 enclosed (heated)...
  • Post in thread: Thoughts on Midnite Classic 250

    There are some number of folks on this and other forums who have or want to get a bunch of solar gear into a trailer-mounted scenario, myself included. Anytime anything gets onto a trailer, and if used for any terrain scenario other than highway and perfect asphalt (no potholes), I'd expect a...
  • Post in thread: Signature Solar said "Will Prowse setup is wrong and dangerous"

    Power strip = test/project work, not production. At some reasonable point in time, turn your test/project *into* production work. Integrate (the world's smallest/cheapest) circuit-breaker panel in the mix. Run real wiring, suitably sized, to outlets. Ground the system correctly. From that...
  • Post in thread: How frequently does your solar system need attention?

    To meet OP requirements of rural, hands-off, retirement ... implement off-grid as primary; grid connection as secondary. Everything else is a sliding scale of values for hands-on, money, complexity, monitoring, automation, etc. You can push one up or down, but the others will vary in opposite...
  • Post in thread: Bought Litime 230AH 12v battery for full time vandwelling, good or bad?

    Don't know your timeframes for everything, but I'd invest in the design process now, before buying more components. The 12v230ah battery can be standalone for now (a single battery), or part of a 12v system design (one or more batteries in parallel for a battery bank) or a 24v design (2 batts in...
  • Post in thread: 3000sf House Off Grid Sol-Ark/EG4 build with "Power Shed"

    We love being off-grid, and would never go back! No more utility bills with endless "fees" for this and that. No more "we're coming on your property, and there isn't really anything you can do about it", and so on. The whole thing *IS* transparent to my family, other than the fact that my...
  • Post in thread: I'm new here.

    Without intending to discourage you, your current learning approach is perhaps leading you astray in many ways ... you're purchasing (unnecessary) items, without really understanding the item's role in a reasonable or modern solar gear setup. I would hold off buying piecemeal any further, as...
