    Xw pro vs solark 12k

    They are able to draw up to 190a if im not mistaken.

    Xw pro vs solark 12k

    The reason i called this a unfair comparison is high frequency inverters have issues that toridal inverters will never have its not exactly apple to apple but it is a look at surge capabilities of both, and you are absolutely correct about the weird naming it is deceptive.

    Xw pro vs solark 12k

    Here is another test of inverters capabilities, this is still not a completely fair test but it seems to only test inversion capabilities of both inverters, I don't belive its fair to test a hf inverter vs a lf inverter as we all know hf inverters do not do well with unbalanced loads.

    Building a 72KwH battery system, help understanding these Li-ion modules.

    only issue with multiple bms's is cost as long as they are decent, if you go with parraleling cells you will need a bms that can balance your parallel groups and it would be advised to use something like "rec" bms with contactors.

    Building a 72KwH battery system, help understanding these Li-ion modules.

    Thermal runaway in your application would be a non issue using a 5kva inverter, maxed out continually your draw on each cell would not even warm them, a thermal run away issue could come from temperature or over/under discharge tho

    Sol-Ark problems by David Poz.. anyone else?

    Your idea of "properly set up" is the problem...he stated his systems are designed to be OFF GRID! So in this config you will easily face some of the issues he presented not everyone will use this the same way, these are high frequency inverters and have inherent weaknesses...all that video...

    Sol-Ark problems by David Poz.. anyone else?

    It cant be a "hit piece" when others have had similar or the same problems, we get that its a touchy point for some but it does not make it less factual these things happened to some...check the video comments or are they also doing a "hit"? As for the exclusive distribution....why would i do a...

    Your wasting your time buying solark if your looking to buy a "american" inverter... great inverter but def not American.

    Deye Hybrid Split-Phase Inverters - Discontinued in favor of SOL-ARK

    Because solark has exclusive distribution for split phase models i doubt deye will make any for sale outside of what solark will offer and using a transformer will incur some efficiency loss...then again it might also solve any imbalance issues...

    Sol-Ark problems by David Poz.. anyone else?

    So they want you to jerry rig a soulution to use your tools with $14k worth of inverters? Thats wild...and unfortunate! They have access to Chinese manufacturing how is it they dont have thier own autotransformer?

    As i understand it deye has certification from sgs who certified the inverter to ul standards solark has the same certification along with one from ul for the logo..deye was selling the inverter in the na market so the cert was advantageous why they didn't go straight to ul i cant say but sgs is...

    Did you open any and read any part? The certificate number is there...the product name/model is there...the effective date is there...after reading the document search "sgs" see if their certifications are any good.

    Hello is there support for daly....deye?

    Jack Rickard said the BMS started most the fires in the early days. Balance resistors heat. This Pack went up today and IDK why.

    Leaving the battery in the tool leads to a slow drain on the battery....so i never leave them in and charge them before use....as long as its not dead i leave them at whatever voltage they are untill the next use....no issues since

    Help me identify this li-ion battery

    Proof everything is dangerous Petty???? but manufacturer defect
  22. Roqm

    Are NMC-based LG or Samsung 18650 batteries safer than others?

    All are safe untill used out of spec...none like over/under charging or to high/low temperature but he mindfull there can always be a manufacturers defect so test for heaters or self draining cells.

    Help me identify this li-ion battery

    Besides the nail puncture test videos how many nmc battery banks do you know if that are "firey/explodey"? The issue is often from thermal runaway due to over/under charge or over temperature beside damage due to an impact(in ev's)....also nmc batteries can do 3000+ cycles( manufacturer and...

    Batteries finally arrived....where do i start?

    Here you can see where the negative buss bar was split so the i can still use the terminal stud to connect batter to pack, just to the left of the split screw was loosened to pry case enough for busa bar to come out.
