I use 10 what solar panels to help charge the batterys for my 24v South Bend , they have doubled the time between charges . |

I have a 12 watt panel sitting on the lid of my infrequently used 'road drill' air compressor to keep the battery topped up and it works a charm - first one got knocked off by the cat and didn't survive the drop onto concrete. I have to remember to remove it when I start the engine (big diesel) or the vibration will knock the second one off ! Just ordered three time switches: http://www.discount-electrical.co.uk/product.php/396116051/timeguard-ntt04-white-24hr-7day-compact-digital-socket-box-time-controller-with-1---2hr-boost--1-minute-switching---28-on---off-programs-16a 720 hour battery back up, automatic Summer / Winter time change over and a fairly simple programming sequence Amazing variation in price between sellers - that one was the cheapest inc VAT and post I could find |

I feel your pain Andrew -- and that must be rough being responsible for holiday tenants in that situation. I'm sure you'll come up with some improvement. When I lived on my houseboat twenty years ago, I had a Heart Interface inverter that charged the batteries at dock, and it had an automatic transfer switch that instantly kicked in ships power as soon as the connection was cut. So when there were power outtages around me in the evening, I'd hear a click, and the slight hum of the inverter, and not even a flicker of the lights. Stereo still working. Computer unfazed. Looking out the ports, I could see the neighborhood blacked out. This happened quite a few times in rural Florida where I spent a few years. Nothing like an independent backup power source! Now I have to start the generator, and that can be a pain in the middle of the night in mid winter. I've still got the inverter and would love to hook it up to at least one house circuit, but it cuts out now, and I don't have the electronic know how to fix it. |

Steve or some other moderator: this thread is in the wrong box, I must have had a brain f**t - can you move it please ! Well some progress: Today I replaced three non preserved timers with ones with a 720 hour back up, so that's three less things to re-set after a power cut. Also I took delivery of an APC Smart 750 UPS and started integrating it with my HP DC6700 pc and Windows 7. Got it to the stage that they talk via usb, and if the UPS is unplugged it supports the PC for a few minutes then shuts it down. Then I remembered a feature this pc has exhibited for some time - it turns itself back on :bang: Tried and failed before to solve it. Several things in a modern PC can kick it off - the network card for instance can start the PC if it sees activity. However everything was disabled and battened down. I re-set the bios to factory defaults - even changed the power supply for one from a PC I know doesn't do this. No avail. A bit of googling found a chap with the same issue, solved by pressing a reset cmos button next to the cmos battery on this same model - blast no button :bang: So I reasoned - remove the cmos battery, short out the battery holder contacts to discharge any on board capacitors and it should do the same as the button. Sure did :ddb: I restored the factory cmos defaults and the system now happily stays shut down when it's been told to - phew !!! Well - almost phew. Now part way through restarting first time, it shuts down again :bang: Second re-start is ok. Need to do more investigation, but AVG has just started auto update and we are going out, so I'll save this investigation for later. |

It should be a doddle for you after your CNC mill epic! |
