    We are working on a human identification method for registration. I have not been able to find a ‘captcha’ style add on for the forums software that is being used, but did find a similaralternative. Hoping it will get implemented soon.

    deleting the bozo posts is getting old.

    Typical DC “wall wart” power cube/supplies are not regulated, or at least not regulated well. Most ofthe ones I have when tested not plugged into a device they are intended to power will read that high.

    IE a placarded 12 volt suppy may read 15 volts, or higher. It is nothing to do with it being modified sine wave inverter.

    However, Some power adapters, and a lot of chinese,let me rephrase that, poorly designed low cost “things” will fry in short time on a modified sine inverter.

    I have purchased items that worked fine and I have also purchased items that fried in the matter of hours on a modified sine inverter.

    I finally last week bit the bullet and retired my trace DR2412(modified sine wave) after +12 years(I lost track of how long I have had it). Replaced it with a Magnum Sine 2800.

    II ran just about everything on that DR2412, some stuff was noisy electric motors especially but I never blew up anything expensive with it. It always seemed to be the <$10 wall wart devices that fried.

    I have been thinking more about this myself. I am a programmer by day and a paid volunteer EMT-Intermediate the rest of the time.

    There are definitely times when I have a hard time convincing myself that a person needs to go to the ER. There are cases when it is seriously warranted. But there are other times when it is It feels more like some people think just because they have a little owie they need to be seen by an ER doctor. Partially because of the mindset that our countries have gotten into, referring to previous comments.

    I have a blood pressure that is considered borderline. I understand what will happen if it goes uncorrected and am for now abiding by my doc and taking a prescription. I also realize if I could shed the 20 pounds that puts me in the overweight and get down to my ideal BMI I would probably not need it.

    I made the mistake of asking about a recurring skin breakouts. At 49 I felt like I should be done with localized acne :)

    Doc gave me an antibiotic, a 90 day supply because she said it would take a while to get rid of. I went for a followup a month later and while it was working she told me that i would probably need to keep a therapeutic level of the antibiotic from now on. No thank you, I finished the supply but I am not going to constantly take a low level of antibiotic. The annoyance of an occasional acne like break out is easier to deal with than the risks of getting resistant to a medication I might need later down the road for something more serious.

    About every other time I am at her office a drug salesperson is stopping by to drop off samples. I see the qty of ‘preventative’ drugs that the medical community wants to prescribe and it makes me sick by itself.

    oh well, probably enough of a rant. Off to blow away;more idiotic spammers.

    I appreciate the post but unfortunately I am pretty sure these are robots creating the spam posts and none of the perpetrators will probably ever see your comments. :(

    Given the quantity that has come if since I got out the mauser last night and blasted them I am not sure I can keep up. We may have to strongly suggest to nick to take the forums to full moderation. The number of real posts per day is low enough that the few that are really posting can probably live with the delay.

    I am a tryin. I’ve been out in the power building all afternoon swapping out my ancient but reliable Trace DR2412 for a Magnum Sine 2800. It is nice hearing the fans runnig without the modified sine buzz.

    Lots of cleanup work to do inthe morning I got it electrical hooked up. But bits of wire all over the place out there and sore arms and legs.

    hooboy, lots a questions Jeff.

    First thing I see that needs clarification is you state that you use 2kw’s a month.

    Kilowatts are a unit of power, it is an instantaneous measure. Power expressed over time is watts per hour, or kilowatts per hour (kwh).

    I find it very difficult to imagine that you are only using 2kwh’s per month.

    A 5 watt device(maybe a small radio) if left on 24 hours a day, for a month would use 3.6kwh’s, nearly twice what possibly your stated usage is.

    So, please confirm how much power you use monthly. You need to define that before getting in too deep.

    I have built one panel in my life, in college back in 1980. Techniques have improved since then, but unless you are extremely tight on money, or want to say you did it. It is much better to latch on to commercial built units. Homebuilding a panel and making it weather proof to where it will last 30 years will be a major challenge.

    I have stuck to commercial panel since. My current system has a power rating of 2.2killowatts of PV. On a good day I have produced close to 12kwh’s, on a bad day, well that is what the batteries are for :)

    There are poster’s here that can answer some or all of your questions. Just need to take it in small bites.

    I am guessing at 63 kwh’s a day that you are all electric? That is about 10 times my daily average. I have gas cooking, water heater, clothes dryer and have all phantom loads on power strips. Y

    How are your soldering skills. The solar cells are very fragile, expect to break a few.

    Somewhere between building that first test panel and gettnig to your crap load of energy production you may want to analyze where the 63kwh/day are going. Invest in a kill-a-watt meter, google it if you are not familiar with it. It lets you see how much you are using on a given device over time.

    Got to get back to work, will try to follow up more. Keep hoping someone else will chime in though.

    I received an email from ebay tonight claiming that they are ruling in my favor.

    There statement is I need to send it back to seller with signature confirmation. But that it may take 48 hours for the information to show up on my ebay resolutions page because of the amount it requires management approval and it must be shipped within 7 days.

    Egads that is nice, except I am supposed to be going on vacation for 2 weeks Friday. May have to make room in the trunk and UPS it from the other side of the country. :(

    to moguitar, I dont suppose you remember the name of the street this ‘gent’ mailed from do you. I wont be so brazen as to compare names and house numbers. I figure if the street name happens to match though.

    If the glove fits :)

    in reply to: What charge controller to use? #64576

    Outback FM80’s and MX60’s are both good controllers. THey are not cheap but they will handle up to 150 vdc open circuit. They have programmable output voltages to match to about any battery.

    The FM80 are rated at 80 amps continous on the output side, MX60’s are rated at 60 amps.

    I run one array at about 100vdc in and 12 volts out feeding it with 1250 watts of PV. The second array I run at 24vd in and 12 volts out and is just under 1000 watts of PV.

    If you use these controllers read the manual closely if you feed themn with over 100VDC in cold tempertures the open circuit voltage will be higher in the winter add snow reflection, etc. One does not want to blow a $500 charge controller.

    Yes. I am at about 40 degrees north and even at this latitude I notice the pronounced northeast sunrise, northwest sunset. I am not so far north though that I losing all that much.

    I have really good siting. In the summer time I have nearly 12 hours solar exposure but the leading and trailing hour or two is pretty wild angle.

    Trackers are just not an option for me though. Lots of surface error and as elnav notes it gets complicated with the larger trackers. Before I added the ‘big pole’ I would hand track some of my smaller panels but now with 2200 watts of PV summer time I usually have more power than what I need anyway.

    The big pole is a 6″ sched 40 pipe with 6 KD205 panels. As I remember shipping weights including the rack and panels there is probably 500 watts sitting on top of the pole. It takes 2 just to adjust the seasonal angle.

    I actually left all my panels at equinox settings instead of bringing them back to summer. Did that partly due to getting some 1.5″ (nearly golf ball sized) hail. No damage but I liked the idea of the slightly shallower angle to hopefully help deflect hail that size(if it happens again).

    WIth the MPPT controllers I am still getting 10-12 kwh on a full sun day in the summer.

    Okay, I just have to ask this of ReBoot. Was the trailer hunting ‘winter sport’ with or without the aid of a gps. Did you always find it on the first snow drift dig? :)

    Your first post, first paragraph is a bit perplexing. In first two lines you make contradictory statements. Are you wanting to be off-grid, or are you. You say both?

    While some car stereos might have a max current draw of 8-12 amps. That is their max current draw. Amps are directly proportional to the volume. Are you planning on running this stereo at an ear splitting volume?

    I’ve used 12 volt car stereos on solar setups and at least the ones I had, for the volume I needed never pulled more that a couple of amps. Granted the last one I ran this way was a few years ago.

    What is limiting you to the 5 amp max? In my area of the US, that is about the average usable amp hours I would expect out of a 20 watt panel with a cheap charge controller.

    That would provide a 5 amp load for “approximately” 1 hour, or a 1 amp load for 5 hours.

    I am trying to put your 5 amp limit in perspective. How long do you plan on listening to this “5 amp” stereo a day, you need to take that into consideration as well.

    Regarding the “capacitor” suggestion, for the power levels you appear to be limited to capacitors near the stereo are not going to gain you anything. From what I know the guys that are doing that, are the ones that have the stereos in their cars that you can hear the bass a 1/4 mile away or more. It is comparing apples and oranges.
