    Any idea on "cleaning" dirty electricity from dual fuel generator?

    I know this is an old thread, but I was just fighting this same thing on an lv5048, and came up with a unique solution. Thought i would share. I tried adding a resistive load to stabilize the output, but it didn't work, then I was thinking of how an inductive motor load backfeeds power while...

    hope you don't use them inside, found that youtube comment: "One of these OLPZ batteries (12v-200Ah) set my basement on fire. Several tens of thousands of euros in damage, huge effort with fire sanitizers, craftsmen's businesses and trouble with insurance companies just because you fell for...

    if you want to make sure the charger is dumb enough, just use jumper cables from running car to your battery. pos to pos/ neg to neg.

    I just direct shorted my brand new 135amp LiFePO4 battery - is it toast?

    sla charger should work, but it will need to be a "dumb" charger. smart chargers read the batteries voltage before outputting a charge. since your battery is effectively turned off there will be no voltage out. so if hooking it up to a charger doesn't work check the charger leads voltage with a...

    New Battery on Amazon and Ebay - Global Power 12V100AH LIFEPO4 - $399! Has anybody actually bought one yet? Torn it down yet?

    if you're electrically handy check the parallel cell voltages, (small 5 wire connector on bms) there are 4 parallel strings wired in series all 4 should read around the same voltage, they are probably severely out of balance. should meter out something like wire 1-2=3.3v 2-3=3.3v 3-4=3.3v...

    How can Current Connected improve?

    not to hijack the thread but freight101.com small business transport. free quotes without an account and in my experience Always the cheapest option. If you live rural with limited local docks, like me everything comes in from the same 2 or 3 lines for the last leg anyways. I have tried to quote...

    How can Current Connected improve?

    based on his comments on other threads this may not give me my answer. Distributors have to honor minimum advertised prices on products, basically to be a distributor you can't advertise lower than list price. Just trying to figure out if eg4 is allowing ss to use lower advertised prices than...

    How can Current Connected improve?

    so I guess the next question would be can you sell the eg4 items for the same prices signature solar gets to advertise them for? or does signature get to undercut all other distributors?

    How can Current Connected improve?

    Why don't you come up anymore as an eg4 distributor? Have you already/ are you going to stop carrying them?

    EG4 waterproof vs server rack batteries for an 6000XP system?

    serviceability. if anything goes wrong with them they are sealed units. if you can depend on timely warranty coverage not a big deal, however if you ever need to service them yourself, rack mount batteries can be opened sealed units are much harder

    Anyone buying these 305ah envision cells?

    yes that's true, it needs some time to react, at which point it becomes hfa and offgasses severely toxic fumes. So like idk, sitting in a hot car truck all day? Do you think that just might qualify?

    Anyone buying these 305ah envision cells?

    It's formed from the electrolyte reacting with moisture, the carbon coating on the cathode is fluorine doped, when exposed to water the electrolyte releases fluorine gas and hydrofluoric acid. It is a lower concentration (aprox 4-10%) but that can actually be more dangerous, as the are no acute...

    Are Signature Solar refurbished items a bad idea?

    Signature Solar's business model seems to be "stand behind any new offering that we are trying to hype, but when things we've decided not to reorder have problems, ghost the buyers unless they humiliate us on the forums" If they are selling something that is revealed to have known problems they...

    Anyone buying these 305ah envision cells?

    how do you know your meter is that accurate? thats a less than 2% variation. I have multiple different amp meters, both clamp and shunt, they are never within 2% of each other. also did you completely top balance all cells before testing?

    Ac Volts bleeding into solar lines?

    "The multi-meter reads 170 volts AC at the solar cable inputs on both inverters with the solar disconnected" ok maybe I misread this, I see this as 170vac between solar input and case...? Or is that between solar +&-? Either way how would that equal shock between conduit and ground unless...

    Ac Volts bleeding into solar lines?

    Ok, here's the question I don't see anyone asking you, why is your dc wiring connected to your conduit??? while your array panel frame and mount should be ground bonded, you should have NO CONNECTION between your dc conductors and array ground. dc negative should NOT be bonded to ground.

    anyone have any experience dealing with Dongguan Ouchi (qucc) directly on alibaba?

    So I've used these balance boards before, and they worked really well. the switch on them has 3 positions off on above 3.0v per cell and on all the time. I messaged the supposed manufacturer on alibaba and asked if it would be possible to get these with the switch set to 3.3v on instead of 3.0v...

    Remove the top and manually balance the cells. They are bad about losing balance. The seller was offering add in balance boards for a while, don't know if he still is. I'll pm you his email address
