    24th January :: ML V=10.49 Y=130Wh What happened to the voltage ?? I was away all day so no usage to speak of. Was fine whne I left around 10:45 am. Some 12 hours later when I returned the system ahd shut down, the voltage being less than 11.

    In checking the batteries I noticed one was not connected Hmmm!
    Disconnecting the other two, after half an hour one was at 12.8v the other 12.3v so I reconnected only the one at 12.8v and all 'seems fine'.

    The other oddity is that the MPPT unit has recored that the batteries went to absorption after 6h 45m fort only 1 min, then went to float.

    NOTE: Battery electrolyte was ??? where. I noted the Victron was reading 2v lower than the batteries so it may have been charging an an extraornidarily high rate. Maybe the digital meter's battery ??

    31st March : ML V=12.70   Y=330Wh Removed a solar panel mid afternoon, so only one 250w input.

    30th March : ML V=12.64Y=310Wh
    29th March : ML V=12.59Y=410Wh
    28th March : ML V=12.65Y=510Wh High yield as used electric plane.
    27th March : ML V=12.60Y=160Wh Low yield as power not used during day.
    26th March : ML V=12.60Y=???Wh
    25th March : ML V=12.70Y=220Wh
    24th March : ML V=12.74Y=340Wh Used angle grinder so yield is higher.
    23rd March : ML V=12.84Y=240Wh
    22nd March :ML V=12.68Y=560Wh Used angle grinder so yield is higher.
    21st March : ML V=12.82Y=210Wh
    20th March : ML V=12.63Y=300Wh
    Reset VD as it had started new day before mdnight, this brought the ML upto 12.63 ~could have been higher?

    19th March : ML V=12.40Y=290Wh
    Strange that the ML is low @ 12.4 and there was 20watts usage overnight

    18th March : ML V=12.75Y=160Wh
    Must check electrolyte again.
    Notable is that the ML is high yet the yeils is only 30w or so about the useage

    17th March : ML V=12.40Y=180Wh
    Left router on all night :(

    16th March : ML V=12.60Y=160Wh
    Although to ML voltage was 12.6 the record shows it was 12.32 when switched off last night and now I have loaded with comp, router and led it is 12.24.
    Yield of only 160w but battery was on abs for 2h and float for 8hr
    May adjust the abs time span

    15th March : ML V=12.70Y=240Wh

    Though the last two days yield has been below 320w the 41Ah battery is fully charged with some 145w usage. Maybe smaller batteries is the key.

    14th March : ML V=12.72Y=220Wh
    ML V =12.72 Check elecrtolyte levels.
    All cell were covered but added aprox 32ml of rain water to each.

    11th March : ML V=12.56Y=420Wh
    10th March : ML V=9.99Y=160Wh
    13:20 Changed Battery ~ removed last of Rolls 125AH and temp using a 41AH car battery that Gavin lent me.

    In general all our products are designed in The Netherlands and manufactured in Asian countries due to cost price reasons.

    You can ask such questions to your supplier, they see the country of origin on the invoice they receive from us.

    The SuperPack is made in China , mainly Chinese technology, only to be used in small 12V systems.

    The normal Lithium batteries LiFePO4 we offer in 12 and 24 Volt are also manufactured in China, the cells are Chinese lithium cells, we design the balancing system in the battery and the external Ve-Bus BMS you need to use them with our products.

    Keep in mind that most of the Lithium cells used in the world come from China, they are the best it looks.

    Country of Origin can be manipulated a bit by buying the cells from China and completing the product in another country.

    Our 12 and 24v Lithium LiFePO4 can only be used for 12 or 24v applications, for 48v Lithium to be used with our products we recommend third party Lithium batteries like BYD and other brands mentioned on our website.

    With best regards,

    Jan Klumpenaar, Sales Manager
