Up and around relatively early this morning, cooked breakfast, the works, then heard that there's a major power outage covering the whole Eastern half of Nova Scotia! Checked and sure enough, it's off and I would have never have known it CBC Radio hadn't told me while I was eating my toast! I'm loving it:p:p:p

    I second that motion. power outage is common around here. I have grid power, but converted 3/4 of the house to off grid power. except for the 220v stuff and my sons room. never really know if it goes out unless a neighbor ask if we have power, or my son yells, dad, did you flip my breaker again. :D

    Re: Gotta love living off grid!

    I'm just wondering what happens when my inverter takes a dive. How long to get a spare shipped & hooked up? I guess I should consider obtaining a spare, along with a spare water pump.

    Re: Gotta love living off grid!

    My GT inverter failed a couple weeks ago and it will probably take another month or two for the replacement. Isn't reliable grid power nice. Don't even know my solar power is even out for 6 months or so just this year.:cry::p

    Hahaha Well Urbandialect, it took quite a few years to reach this point, but I'm extremely happy with the independence it allows, and it gives great satisfaction indeed. I hope that eventually your system works as well as mine. The whole thing gradually grew into something beyond my wildest dreams, never would have guessed I'd one day be running the whole house on it, but there it is, and I owe so much to BB, Niel, and others who helped and tried to guide this stubborn mule along the right path :D

    BB Bill,

    Sorry to hear that you lost the GT inverter. Funny tongue in cheek humor.

    Believe that this is the second GT inverter that you have lost, and also complete replacement of panles. Good thing that you chose a good installer.

    OOOPpssss, back to topic:

    As there is no grid here, am very happy to have reliable power (knock, knock), much more relaible than my PG&E Grid "power". And, if the power ever goes out here, know who will be fixing it, and am able to get to it on my schedule.

    Off-Grid is not cheap but at least it can be fairly reliable -- the only power outages here have been because needed to change, or add something.

    Good Luck, Vic

    Re: Gotta love living off grid!

    Vic,

    Actually--the Second GT inverter was a free upgrade to the first one already out of warranty (and still working fine--I was pretty happy about that :D). It was the second one (new and improved for safety and longer life) that failed after a few months (at the time, evening on only running a 100 watts or so--and popped the 20 amp 240 VAC branch breaker when it failed). :roll:

    The new GT inverter (and/or with the new solar array) seemed to output ~15% more power on average.... Was a good combination.

    For whatever reason, Schneider is running 4-8 weeks or so for a replacement inverter.

    More or less--just a data point on generating your own power (off grid) and having belt+suspender+staples+glue for emergency backup. You never know what will fail and how long it will take to repair/replace.

    Re: Gotta love living off grid!

    I got a spare for that...

    Always good to have spares, I'm celibrating 10 years of being off grid, and I've only had one major outage, when I in advertantly left my inverter on when I took an extended bicycle trip to Florida 7 years ago, I had also taken down my array leaving a single panel hooked up in the shade. I came home with my batteries fried. Just 2 Golf cart batteries then. I have spares for every thing but my new froklift battery, mostly from things I've out grown. Don't think I could quite get my whole array going on 24 volt, but next year I'll likely go for a Midnite classic, and will have spares any but a dead battery, I could even weather a couple dead cells as I could do a 12 volt system.

    So 12 hours outage then and 10 minutes installing the forklift battery (and like time installing new or updating equipment) is all the down time I've had. I have reduced my usage to near nil due to long periods of cloudy days but that has not been a real problem, though the alternataive was to have a backup power source.

    I agree, It's good to be off grid!

    Re: Gotta love living off grid!

    I have the best of both worlds! :D

    If some component dies in my off-grid system, I can just plug into the regular wall outlets.

    If the grid goes down, I only know because the ceiling lights go out! (And that has happened a disconcerting number of times since I got the system set up. Grid used to be so very reliable around here...) I get a kick out of reporting outages to the electric company using my computer to access their website via my cable modem connection - all powered by the off-grid system at that point!

    My system is still pretty tiny compared to my usage. It'll make about 5-6kWh/day in summer, 3-4kWh/day in winter. But that's enough to keep the essentials going without a generator running in the back yard should another big ice storm come along. (And those have been disconcertingly more frequent in recent history as well!)

    I also have backups for the backups as it were. A separate panel feeding a 12V battery / CC for the ham bench. I could run a few items off that. A 1500W 12V inverter, worst case I could rearrange the main system to use it. And (getting REALLY desperate here!) I still have the Harbor Freight panels sitting around, hook 'em to one of my small AGMs and I might be able to keep an LED light on with them! :p (And if All Else Fails I can still fire up the generator!)

    did not your utility get curious as to how you were able to report that outage that way if your power was out or are they just that dumb they couldn't put it together that their power is not magical to be able to mysteriously power your computer and modem to report it?:confused:

    Re: Gotta love living off grid!

    Most cell phone browsers today can handle full web sites. I use my cell phone as my Internet connection so I could get on the net using my laptop and cell phone. The local cell site has a genset. So there are 2 ways with no backup power at all.

    Via cable modem is trickier. You could power it with an under-desk UPS, that is the easy part. The problem is every 1/2 to 2 miles there is a pole-mounted amplifier and not all of them have battery backup. The ones that look like big green boxes do, but even then that battery isn't going to last very long.

    Re: Gotta love living off grid!

    5 1/2 years ago our system turnkey cost was about $80K (not including the back up genset) which includes all civil work, hardware, labor, electrical in conduit etc. Very happy with the design and install which was done by the same people who are residential and commercial electricians and solar installers. The did all the home's electrical too.

    While we tried to engineer it right, we didn't know what to expect especiallly pushing two variable speed A/C compressors and air handlers in addition to all the gear in the house.

    Last year, we added four extra panels to better balance the house's two zone power consumption (closer equalize the zones voltages). For some reason one zone used about 15% more power. We also replaced the 5 year old Trojan L16s with the newer L16 REBs' which are using quite a bit less water than the older version.

    I think the prices have come down since we built ours for comparable components by maybe 10% - 20% +. And, the newer MPPT inverters have a cleaner sine wave, panels are 225 w, charge controllers handle more too and the overall technology is probably better all the way around. Windsun and moderators can correct me.

    The system's photos are posted somewhere on the forum.

    Last week, we replaced the five year old 15 KW Generac 1800 rpm unit with a Cummins Onan brushless 20 KW genset. The new Onan seems to be a fine piece of machinery. Glad to see the Generac go for many expensive reasons. The Onan installed was about $13K and essential to our lifestyle and remote location.

    Yep, that's my limiter right now. Most outages don't last that long, but I've had a couple that were long enough to determine that the cable company's box dies about 2 hours into an outage. The box I'm tied to sits in my next-door neighbor's back yard, wonder if the cable co would let me power it during outages? :p (Although I'm not sure how much farther that would get me - guess it depends on how widespread the outage is.)

    Ah well, I now have tethering on my cell phone so if I'm still online after two hours of power outage I'll just turn that on and connect through it! :D

    Re: Gotta love living off grid!

    My favorite moment of this sort to date has been at night watching bright blue flashes on ice covered trees in the distance during an ice storm while my off grid system was just fine. Now, not being able to get out to the county road due to tangled lines and trees down on the road is another matter. I do have a back way out but it's best traversed in a log skidder!

    Years ago an acquaintance of mine who had a massive house with a large diesel genset on an auto-trasfer switch in a concrete bunker under the garage didn't notice that the grid had gone for three days, which is how long it took to run the genset out of fuel. You could sort of hear it running in the boiler room as the fuel oil lines ran through the generator bunker in plastic conduits that carried the sound, otherwise no indication. The only reason it ran out after three days and not a month on the massive buried oil tank for the building's heat is I never connected the transfer pump. I didn't want to see that nice Perkins engine get wrecked by high sulfur fuel!

    Re: Gotta love living off grid!

    My house and garage are essentially still off-grid. The grid tied 10kw system only sells to the utility. We installed a load system with a few circuits for some loads and battery charging.

    Latest power outage was only noticed when I looked at the Enphase website and saw a flatline on my power curve. I flapped around for a while thinking I had hardware problems...then phoned a neighbour who said that, indeed, the power was out. I kinda felt silly:blush:

    I had a similar experience not long after I installed my battery backup system. A friend called to ask about the best way to drain her water system in case it got too cold in her house (this was during a 15F cold snap). I was completely confused because she's farther down the trunk line than I am so if she's out, I should be out, but I told her our power was fine. Duh, we had been running from battery power for a half-hour and I didn't even know it. I had to call her back and sheepishly admit my error. :cool:

    and assorted stuff about celebrating 10 years off grid, then 2 days later I find a honey of a deal on 2.2 acres with a 2000 16x60 mobilehome on it ($12,000 the pay off of the mobilehome the guy was buying a house with his fiance') So I went into the ugly musolium of the local electric coop and signed up, true cruellty $25 a month before you buy any electric...

    I doubt I'll convert the MH to gas, more likely I'll build a cabin and run a water line out do a composting toilet, and french drain for the grey water. Do solar and pay the water bill. Then rent the MH as a room (though I'm in Missouri and there are no restrictions a seperate residence would require a larger septic to handle.)let the 'roommate' pay the electric.

    Re: Gotta love living off grid!

    All you off grid guys are lucky. I'm still trying to get off grid, but I can't get my usage below 250kwh, which is the magic number I need for the system I want. IE, one that gives me what I need, but doesn't break the bank. :(
