  1. Bobajob is assume you have 35mm panels and I saw a plastic frame for sale to mount them to the roof. I am leaning toward flexible panels and read how one guy used his with Velcro to affix it to his camper as they are less than 3mm thick but Sikaflex could also be used. Looks to be a smarter installation and the panels are tougher although they generally have lower output. 2x 100w panels might suffice. Thanks for giving the feedback you did.
  2. Certainly does, also open campfires! No, the 700w genny won't power a 1kw hairdryer and the 3kw one is too big and heavy, I'd prefer to leave it behind. Plus the 800w microwave has built-in wiring. I don't fancy re-plugging and trailing cables across the habitation area every time I want to use it.
  3. Thanks everyone I've read and re-read your info many times. Sad to have returned home from a site in the New Forest but at least I have good Wi-Fi to reply now. In September we will be going away again for 16 nights. Rather than doubling up on the solar panel and battery and still being short, I had the idea to take the 8.2a 12v dc output from my 700w genny and use it to feed the batteries that the inverter is drawing from. However I realised in this case it's only an extra 100w. To be sure for the first time I'll take the 3kw genny and connect this instead of the inverter. Will buy a 2kw (4kw peak) inverter using 3AWG cables? I will only need the genny for the few minutes the high current devices are in use.
  4. I'm planning to go off-grid for the first time, I think I have the refillable gas sorted for fridge and heating and thanks to the forum search function and have learned a lot about solar. I would initially get a 100w flexible panel and a 20a (MPPT not PWM) controller in case I need to add a second panel coupled to a 110ah battery that would be connected in parallel to the caravan battery which is the same size. I will change all the 12v and 240v bulbs to LED. I will boil water and make toast using gas but would still like to be able to use the 800w microwave (max 8 mins) and Mrs Limecc the 2kw hairdryer (max 4 mins on 1kw heat setting). I'm unsure whether to get a 1.5kw or 2kw pure sine inverter but because of quiescent losses it will be normally turned off when not in use. I have a Hyundai 3kw and Clarke 700w suitcase generator, the latter is quite compact and might be useful to prevent excessive battery drain when using the high power devices. 1. If the inverter and generator outputs are connected together to the caravan mains input, will they work together ok or will they be in competition regarding the voltage regulation? 2. Regarding my Fleetwood PDU2 caravan charger/distribution unit, I understand I need to turn it off to prevent losses from it trying to charge the onboard battery, but if I do this won't I lose the 12v to the Alde heating and lights? Many thanks for your thoughts.
  5. This is a beast of a car that doesn't break a sweat when towing. Unlike many Japanese marques it's over-engineered in typical German fashion, for example the V6 gearbox was designed with the 500hp V12 in mind. I know the Touareg (another beast) has a different spec with a factory fitted bar but even with the lower spec fan I doubt there has been any real life overheating problems. The only thing I worry about is the day the electrically deployed factory-fit towbar fails to deploy leaving me stranded, but that doesn't apply to you. I disagree slightly with Commander Dave because dealers all have part number info at their fingertips, more likely they may be reticent to commit to an answer or actually look. Fans (e.g. for my year) appear to be based on engine variant: http://www.oemepc.com/audi/part_single/catalog/au/markt/RDW/modell/AQ7/year/2012/drive_standart/675/hg_ug/121/subcategory/121091/part_id/258255/lang/e#sec_5
  6. Just wondering why many drivers seem to risk doing 20mph faster than me through motorway roadworks? Do they know something I don't or what? Seem to recall Clarkson on TG saying to change lanes between averaging cameras? Are the lanes processed as individual channels? What gives with these people? Do they have these jammers?
  7. Used to get as low as 14mpg towing our 1700kgs twin axle with my dearly departed 2. 8 V6 petrol Passat, I don't hang around and go just a few mph over speed limits but not so much to worry about getting pulled. At least it was burning lpg so not bad in real terms as it is generally half price of petrol per litre. With our 3. 0 diesel Q7 with the same kind of driving it returns 24mpg on the fuel computer and with the 2. 0 diesel Smax I had briefly that returned 28mpg all with the same van to the same destination. I'm a firm believer in remapping, but for economy not power. A few on here disagree but there's no doubting the revised torque curve made both my diesels even better suited for towing.
  8. I was wondering if the temporary boost to the 3010 water temperature can be made permanent somehow? I like having more stored btu's as it means you can have a longer shower before it goes cold. Useful if more than one person is showering.

    Re-Google! Logiclee already gave the correct info comparing coal thermal efficiency to a modern diesel engine which does approx 5% better. I was surprised when he says gas has overtaken coal as the larger generation but am happy to concede as I am not up to date. When I worked at Ratcliffe our competition was never running because of the oil price. They even mothballed some.

    No I'm not going to shortcut your own research, just use Google and start by finding thermal efficiencies of fossil fuel power plant vs modern IC engines. Non-fossil fuel plants arguably do not save co2, the calculations are near impossible to work out.

    Pardon my skepticism but I believe a major factor in the push for electric is the corporate profit potential brought about by forced legislation. Battery charged electric cars do not produce less co2 - only the point of production moves and then when you take into account distribution losses and extra co2 used for car manufacture and battery recycling the whole argument falls apart. Alternatively, green agenda groups would like to prohibit private vehicle ownership by cost while conveniently ignoring that they burn little fuel compared to that from commercial shipping and aviation operations. The economics are completely wrong and we present an easy target. Change behaviour of industry first not the other way around. The most gas guzzling towcar produces far less environmental impact taking us and our van for a two week holiday. Compare this to a long gas guzzling aircraft journey to some country where it's so hot the apartment air conditioning must be permanently on. Where are the lobby groups against these kind of holidays(!!)? Electric cars actually make more sense if you remove the battery. Energy density is the key. Whatever happened to hydrogen fuel cell technology? Filling up could be made very simple and quick. Not sure how it is currently done but perhaps a quick release exchangeable cell system could be designed? Alternatively stick with fossil fuels, continue to improve thermal efficiency and clean up the exhaust. IC engines have better thermal efficiency compared to power stations, I'm sure no2 and so2 exhaust scrubbers would be viable because cats and dpf's already are.

    What's the thermal efficiency of a clean (fgd) coal fired power station vs the thermal efficiency of a modern IC engine either petrol or diesel fitted with cat and particulate filter? Nothing saved in terms of co2 output per mile who knows how much worse?
  13. From my highly biased perspective I can say that either car will do great but we both know which would do the job best. If both are automatics then I would also consider which if any has air suspension. Heavy twin axle vans pitch differently to single axles and when you get a big one at speed such as sometimes from a section of motorway or dual carriageway that has suffered subsidence then they pitch with far greater force and I found that coil springs can fully compress and mudflaps can scrape the road. With my Q7 bottoming out is eliminated even when the rear is piled high with heavy awnings and other weighty gear. The ride height is self levelling and the spring rate is non linear. Q7's were also sold with coil springs which simply wouldn't fare as well. Just another factor for you besides engine torque and power.
  14. AJ mentioned Purple Rain I'd never heard of that but it sounds similar to the original 'Dragon's Breath' which turns red in contact with iron. Brilliant stuff! Slightly soapy so it also removes grease and tar, is effective but had no detrimental effect to the wheel when I forgot about it and it dried on. Best place for reviews and recommendations of all valeting products is detailingworld. co. uk forums where the autists and professionals hang out.

    Audi Q7

    Does yours have air suspension? Is it recommended to tow in 'comfort' mode or 'dynamic' mode? Touareg or Q7's don't break a sweat when towing so no real need for upgraded fan in our climate.
