If you are looking for ideas you might consider something along the lines of what I am planning. I like working with "junk", recycling stuff that previously was used for something else. In the unit I'm planning (Will's "Classic 400 Watt") I want to be able to adjust both for angle to the sun...

Steve_S.... I am low on the learning curve with all this but from what little I have picked up I agree completely. efficientPV....What I was looking for was something that I could put in my pocket/glovebox of car and readily have available so when a unit was presented as sine wave I could at...

No ice flows... Olympic Peninsula, Washington State. Photos? This get offs topic real quick...I'm guessing you want photos of local geography...a quick search yields only one on this machine of the island...I have lots of animals: pileated wood peckers, coyotes, wood ducks, owls, hawks and of...

For me it isn't a case of "going over to solar" but rather adding solar to my existing repertoire of ways to make light, power some entertainment and make ice when needed. I lived and sailed for three years with only kerosene for cooking and lighting. And for many of the islands I visited this...

Congratulations Will on the new Forum! So I got this message "You have been awarded a trophy" Perhaps Will will elaborate just what a trophy is. I don't belong to many forums and so this is new to me. Wiley

Like chrisblessing I have been using tankless LPG on demand for a long time, well over thirty years. First a Bosch unit then went to a Vailland unit with the new house. The new owner of the old house didn't want on demand so I got that still functioning Bosch unit as a spare. We also have had a...

Ped, Yes very close on that though it varies. Now that being said I have sailed from Hawaii to the mainland and from Hawaii to the Marquesas each passage with an onboard tankage of 76 gallons (not including two five gallon bailout/change of lifestyle plastic jerry cans). Here in the PNW water is...

Joey, I built my home and when I was inspected my the state electrical inspector he demanded that I change the ground wire from ending at the well casing (after connecting to the ground rod) to a situation where the last item connected was the ground rod. So the ground wire went: panel to well...

Morth thanks, but we cook on gas. Thanks for the suggestion Delta-V, I have a box fan. It's a three speed model nothing fancy but actually made in USA. I first checked speed and sound on a house circuit and then on this inverter. I could detect no difference either in speed/forcefulness of the...

Supervstech, Absolutely! I will be quite happy if the unit handles 1000 watts on a sustained basis. The advert says 1500 sustained so I'm hoping for 1000. I was looking for a unit to power my home theater when the power goes out. At present I would fire up the generator and we would retire to...

I feel your pain. I've looked around myself and it would appear that you are going to have to source the parts from a country with an emerging economy, a place where things are still done in the old ways. Not too many years back I was quite into letterpress printing. Basically dead save for an...

OK experts: So couldn't one build one out of an old UPS? That way it would have the 120 volt charger as well as low voltage cut off (if one connected it to a gel cell battery... which is also connected to controller and panels)? The inverter might not be sine wave but probably better than most...

This is quite the issue with paying a premium as an early adopter for any new technology. Plasma & DLP TVs etc. are easy examples where even big name companies spent millions on new factories only to have technological advancements make them obsolete. So pay premium for a lithium iron phosphate...

You might consider this method to meet the grounding requirement. It is what what used in the service to my shop: https://www.ecmag.com/section/codes-standards/what-ufer-ground-concrete-encased-grounding-electrodes Hoping this helps, Wiley

Steve, Thanks but no thanks for offer of dead inverters. The specs on the smallest Yiyen unit are impressive. I don't have as much problem buying Chinese produced stuff.. I'm old enough to remember when all Japanese made goods were considered inferior. I probably will ask for a quote if for no...

I would be surprised if it has a rating sticker based upon its vintage. I have a panel from 1979 and it measures about 16 inches by 41 inches...whatever that is in metric as the panel I have is French made, and I bought it new in Bora Bora in 1979 but that is not the point. The point being a...

Update: Written on controller 11/25/17 which either the date of manufacture or date of installation. It would appear the ebike is just over 6 years old. Also the wiring is internal and runs up along side the seat post. The seat post is contained and held in an eccentric tube inside of a tube one...

Hi Larry, Will do, although Will may want to move this thread to "Chit Chat" as it seems less solar and more tangential. Our goals are similar. I still wish to end up with a simple, robust and stand alone setup where the battery can be directly charged from a solar panel(s) and controller...

Well NMW if you really think they are worth something maybe we can work out some sort of deal where I ship them to you, you sell them and we split what you get for them. But even if you are up for such it will have to wait as the docs are not thru with me yet. I have a cardiac catherertization...

You might consider these: http://www.ventedcatheater.com/ These have been around for a fair while (I installed the 120 Ac model in our home 25 +years ago). They seem to get good reviews by the RV community.

Here's an oldie but still interesting for those thinking nuclear apocalypse: https://nuclearsecrecy.com/nukemap/ Lots of variables one can play with to see what could happen.

b.james, I posted to disasterprepper on youtube who presents himself as a NASA scientist/engineer and seems to know his stuff. He replied that while he had not explored it fully, he did expect the bms to be damaged or destroyed after an emp. That's a interesting idea...prying the cases apart...

I believe you are correct: it seems to be dependent upon the controller. My cheapo Chinese PWM has a definite warning that damage can occur, my older Flexcharge (also PWM) states an order for assembly and disassembly of the system that is quite exact (including to connect negative from charging...

svetz, There's a reason I referred to it as a rabbit hole. I read the report, and have read many of the updates. One gets to draw ones own conclusions IF one believes such official reports. I have also read several of the declassified reports which were released under the Freedom of Information...

Today marks one week since I had a pacemaker installed. And with it came a list of activities that it would be best I no longer do and "things" it would be best that I no longer linger around. Among the former is arc welding, which while something I didn't do on a daily basis, was a skill I...

Thanks for the come back. It's a rainy day here and I decided to find out more on a nagging question I've had on what I perceive as the weakness of the lithium iron phospate (Battle Born 100 amp battery) that I have been considering. On a owner built lithium battery (like Will describes) one...

There is a significant amount of info available online. http://www.empcommission.org will get you started down a fairly deep rabbit's hole. There you can link to the US Commission's official report and also to some updates. The book "One Second After" written by William R. Forstchen describes...

I have 5 pair of 50 amp Anderson connectors on their way. I paid less than US $15 including shipping. The company is Chinese as are the connectors, so that may or may not be an issue for you. I have dealt with this company for a couple of years and have had no issue with their products or their...

Steve, I sent an inquiry to Yiyen for prices and data on their APC units. I received a reply this morning: "Glad to receive your message. This is Allen sales manager from YIY company. For the APC series 1000W 24Vdc 220Vac EXW price is 150USD (MOQ: 2 PCS) APC series 1500W 24Vdc...

Gehowi, Love the solarium you have in the background. Did you build it or have someone build it for you? On your mobile unit: What did you use for the rotational pivot point? Did you simply butt weld the vertical support to the cross member? Could you show a close up of that portion of your...
