    ### 2018
    **Feb 15th** Having collected Batt 2 from Gavin's where it has been on >14.5V charge for three days, I've topped up the electrolyte and permanently connected 1 and 2 together. They are currently connected to the other pair (3 and 4) and at 11:40 are charging at 15.33V

    **1st Feb**
    08:40 V=12.82
    11:40 Connected to Batts 1 and 2. In 1 minute V=15v
    12:10 V=15.52 A=13.7(for 3xBatt)
    15:05 Disconnected
    **2nd Feb** :: 02:05 V=12.95 :: 10:00 V=12.83 :: Some charging
    **3rd Feb** :: 00:40 V=13.00 :: 09:20 V=12.87 :: Some charging
    **4th Feb** :: 10:35 V=12.87 :: Charging 6hr >15V

  • Inverter Detail

    Managed to retrieve an old extension lead to run a 4" angle grinder, but at 710watts the inverter cut out after 1/10th second so I'm researching inverters that will do 1Kw

    Looks like a Victron may be good especially as maybe 'Made in India'

    **January**
    **17th** Using this alone
    **08:10** START
    **10:30** 15.54v 9A Connected Batt 2 Yield went to 14A voltage to 15.35
    **10:50** 15.58v 11.1A 190W
    **12:45** FLOAT so SET Float to 15.64 > 15.77 9.6A
    END 7 hours at 1A = 84W 12.13V
    End voltage is 12.2v at 0.4A History usage 190W See image at

  • Discrepancies

    **1st Feb**
    When yield went over 1Kw there was no bar representing float.
    When I disconnected load and reconnected no Load current was noticed so appearing to add another amp to battery.
    Later again similar switching load on and off takes a while to show any current draw.

    **19th Jan**
    Absorption set to 15.46 Live readout 15.72 :: some 0.26 higher
    Cut off voltage set to 12.13 cut off at 12.35 :: some 0.22 higher

  • Update 8th Feb

    Victron connect automatically updated to V4.3

    The noticeable was the removal on the graph of absorption and float bar if they had not been implemented.
