• Have extended the cooper strip to a piece of copper pipe some 4 to 5 feet of which is burried in a shallow channel that is used for rain overflow, to help conduction. The copper strip can be seen @ https://unveiled.info/solect/cables-from-panels; the PV frames need to be connected to the top strip along the roof batten

    May 4th Finished, a bit roughly, joining the copper strip parts together and the strip to the ground pipe.

  • To be explained in detail

  • Bought Victron MPPT 150|60 from Barden UK at £460.66 to manage 3 x 250w REC pannels.
    750 ÷ 12 = 62.5 :: 750 ÷ 15 = 50

  • Batteries are 250Ah @20 hour rate. At 12v that's some 2.6Kw :: At 14.5v that's 3.68Kw of power to charge.

    If battery doesn't go below 80% then 800w should be fine or approx 1 good hour of sunshine. OR 6 hours of peddaling???

    Fri 7th I connected one panel, via the Steca Controller, to one old battery. Used it as load battery and measure a use of 10Ah total.

    Could see from the Steca the Asus 900 uses 1 amp

    Sat 8th Since then I have 2 old 50w panels connected via the Steca to one old battery. The other old battery I have topped up with water, which was a bit iffy as it was a sealed battery. The six cells needed about a litre so hardly surprising it/they were almost unrechargeable.

    That battery as end of day on the 9th was rated as 52% charged, by the next morning is was 48%


    Switched old battery. Bat I received 25Ah charge via Steca and was at 80% when disconnected.

    Connected two old panels and one new REC max charge rate was 4.4 of 6.8 generated? Will fill with water tomorrow.

    Bat 2, filled with water 2 week ago, was at 3% charged at connect. It rose to 12% at sunset, 15% by 2100 hours and 18% now at midnight. 19% at 0100 How ??????

    At 0900 theSoC reads 23%??? and now at 1200 the sun is up but it is overcast 0.6A charge, 12.8v Soc 25%

    Tue 2nd Dec 1140 Soc 54%


    2015
    Jan 1st 2015 Soc 61% however the battery seems to be discharging quite rapidly down from 80% two days ago. I should check there are blocking diodes in the each of the two panels.
