barck005 Posted May 23 Share Posted May 23 Pardon, ive only only crashed coursed myself in most of this. Whats the latest trouble with the receiving of your products from china? how many boxes is it? Im sure I can find the answer but where are you guys located, I saw something about the shipment arrived at Long Beach.... so I assume your'e west coast...? If you're getting the runaround, I have a truck that can get you what's being held up at Long Beach. I'm In Claremont and Long Beach isn't too far from me. I like to help where I can although thats a lot of precious cargo to be trusting into someone whose barely made an appearance on here. I have a question and forgive me its not meant to be insulting but or the guy having the washer machine isssues with the GS inverters, I think he said something about using an extension cord and I assume he uses the same set up for the other inverters that run the washer fine, which to me rules out the extension cord not being the proper size for the amp draw, which makes me wonder if those GS inverters have as close to a pure sine wave as possible because if they rant producing a near closeness to a sine wave then I believe you would be experiencing funkyness with the washer and using those inverters. Maybe something isn't working right or came lose inside and they arnt producing the sine wave they were designed to produce. Ive worked with electricity for about 7 years now, one of those years was self taught, another one of those years and half was thru schooling, and three of those years were professionally as an apprentice and then I had family stuff happen and I left the professional world and engulfed myself into the battery world and inverters and the different battery chemistry and how to charge them properly and how to maintain them. then I got into trying to recover flooded LA batteries and stilll try when I know there aint no coming back from an initial voltage reading of 1.7 volts in a 12 volt battery but still I try. so when it comes to inverters and batteries I only have my personal experience to offer and the knowledge I read from online sources and from people in forums, and one thing I read was no matter what youll never get a true sine wave from an inverter. there's just a bunch of things I don't really know too much about inside an inverter that slows the square wave down to have it more closely resemble a sine wave and so I just bout a scope meter to find out for myself. So another thing about that I came across is that when a machine or motor or like the clothes washer is expecting a pure sine wave and it receives a wave form, from an inverter instead of the nice wave form you see on the graph of the +180 to +0 to -180 and back up again, its like being punched repeatedly over and over again to the machine instead of it gettin punched at those above degree points. basically it stresses the motor out and is possibly making it draw more power from the GS inverters. Waveforms that arnt what the device is designed for will also lower its life expectancy. its just something read and have never been able to test before. but I think if you invest in an isolated transformer one thet does 120/120 as the primary and secondary then it will clean up the wave form just make sure to protect it w a fuse or similar overcurrent device. From what I've been reading here tho, I see only quality workmanship going into the products so it could be that extension cord not being the proper awg size and it being too long. you get a voltage drop every 100feet unless you compensate w a larger wire size. also,, I have a question and ya I shoulda done the quoted thing about the washer machine not working w the GS inverter, how are your batteries set up? or the bank? you said just one powered it fine w the other inverters but what's the bank set up when you use the GS inverters? not trying to insult anyones intelligence but I see a lot of parallel set ups not set up the most effective way. most people daisy chain them one battery to the next but you're suppose to have each battery connect to one source such as a bus bar or wire nutted to a larger size wire that then goes to the load. see the pic below for reference. anyways just trying to help and I don't mind loading up on some boxes if they stuck at port or what not. not asking for anything so there won't be no bond bullshit or whatever they trying to do these days for imports. might be a dumb question and I assume its a cost factor but can't you source what you source from Canada or here in the states? or Taiwan or Australia? or Europe? is the tariff just on Chinese goods? Oh I remember now, about the fans and sourcing them, please try and use brushless and not ball bearing . I hate fans that die because the barring wear out or rust or whatever. my friend had some AC powered electrical video display advertisement billboards you see off the freeway cooling fans. had four of them. dropped those bastards in a bucket of water while they were running and didnt notice them in there for some time. those things later almost took my finger off but they were solid. I think the only company that makes quality products in china is and it won't be spelled right but its something like genzing or Shenzhen products. you see their name on a lot of dc adapter wall plugs. http://www.cooltron.com there's a US dealer and then the one in china. anything Shenzhen is usually quality from china . they have good lifepo4 batteries too. not sure if there's fake Shenzhen companies and that link may or may not be what you're looking for it was just more so for reference of the company. if you have a way to have the fans be powered on utility and then switch to battery when it senses loss of grid power that be cool. the less being sucked from the bank the better if utility Is available that is. youll also want to have one fan in one going out otherwise you willl have negative pressure which a lot of computer type fans don't handle well. so to alleviate stress and premature death is to have an in and an out. you can have both going out but have the right amount of inlet holes to lessen negative pressure stress on the fan motor. fans that do well with negative pressure are inline duct style fans like the ones you see pot growers use. they attach them to a carbon filter that restricts airflow to the fan making the fan have to work harder to blow air. but inline duct fans are built for that pressure stress. computer fan are not. they burn up or won't push air if the negative pressure is too high for them. personally I don't care about sound w fans. it turns into white noise after some time and you don't even notice it and can fall asleep to the constant hum sound or fan moving air sound. I know heat is a killer for electronics and their performance, I think most people would choose performance over a quiet fan but everyone is different. you can muffle the sound some by adding a duct behind and in front of the fan or make a 90 degree angle for the air to encounter. it will lower the sound and won't hurt the performance as long as you don't make the path smaller then the fan diameter. alright well that's about all that came to mind from reading 20 pages of this topic. haha.
