    Eskom is much stronger under Marokane than it was under De Ruyter

    Yea unfortunately the baggage we carry affects everything No problem can be assessd in SA bassd on what acctualy happened The race part has to come into it It does not matter how non racist we claim to be (changed men) That muscle memory will pop back up at times And we have to reflect...

    Eskom is much stronger under Marokane than it was under De Ruyter

    The change that makes eskom look good is the fact they have to burn way less diesel Arguably they can't take 100% credit for that Those units are the most expensive to make So naturally it will have a big impact on eskoms bottomline Not forgetting all the hefty increases was blamed on...

    Navasolar Trolley Inverters

    Ok so if we take 1280wh and subtract 25% loss. That would leave us at 960wh with 400w load that should give approx 2hrs 21mjn run time You got close so capacity isn't too bad No the runtime with lower load cannot be calculated bassd on short run time Ie the inverter self load stays the same...

    Navasolar Trolley Inverters

    Imo Too much guess work ie what is the device actuall stanby usage And efficiency depends on load The qouted efficiency will likely be either worst or best case scenario You would have had to do a baseline run to determine device losses with particular test setup To be able to deduct on...

    Navasolar Trolley Inverters

    Imo with inverter setups With drift and software bugs causing anomolies at times I would only deem something a real problem if you can replicate the discrepancy from a known full battery /capacity test And even then ignore the soc Only deem the battery full when it completes a charge cycle...

    Navasolar Trolley Inverters

    Yea the charging measurement is easiest Plus the charge currentn is a constant normally Sure the voltage does varry a bit The biggest chunk will be around the same voltage So lets say 27 2v at 29A will be 0.788kwh in a hour So then measure charge window hrs example: 2.5hrs x 0.788 =...

    Navasolar Trolley Inverters

    Yes very minimal settings I was more referring to bms settings of the battery These settings plays a big difference on how these devices behave And manufacturers don't always have safe or sane settings I have a shoto battery that has a very conservative pack voltage 54v for 15s 3.6v per...

    Navasolar Trolley Inverters

    Yea so that is where this bugs can throw a curvel ball with wrong assumptions Often if something goes wrong Best is to fully charge and observe if the same problem happens again And naturally knowing the shortcomings of the machines and make sure you are not in software bug territory I...

    Navasolar Trolley Inverters

    Yea and the same apllies to flloat voltage Often debices are set yo float at 3.45v per cell While cells will rest at 3.3?v So this voltage will also disapear on switchover A lot deoends on the machine settings. Iften settings we can't change When device charges the battery will hit...

    I thought the charge amps was at 29A

    Navasolar Trolley Inverters

    Something that can plague voltronic types Especially with light load If you only use it for short power outages The voltage of a lifepo4 does jot drop as much as a lead acid would have So the device does not trigger a charge cycle even though it did discharge i don't know what voltage...

    Navasolar Trolley Inverters

    It still has a cable even If the battery is in the box But yea you have a point the cable will be shorter with smaller mpact But still the only way to really know is capacity test as voltage is really unreliable ie we don't know if the battery was full residual charge voltage disapears...

    Navasolar Trolley Inverters

    Not reliable at all And the voltage the same As the inverter gives battery volage at inverter not battery terminal So depending on cable.lentgh Any observation via voltage means nothing too The bars is based on voltage with lead acids known curve which does not match lifepo4 So yea if you...

    Bitcoin Thread 2 Satoshi

    Funny how people cannot see good or bad notions on both sides Ie cannot accept negative criticism in their belief structure Or positive in anothers belief structure So easy to see where the retards are Most likely those self assured idiots that think my cult/religious view is the only...

    Bitcoin Thread 2 Satoshi

    Firm believer in what bitcoin was Yes bitcoin was destined to fix a lot And then proceeded to break itself I don't know if there are enough cult members to sustain it past its subsidy phase
