• 2nd Day Problems

    **9th Jan**
    Grey day so few photons. The problem I have is the inconsistent readings so see these screen shots taken from 15:13 over the next 6 minutes.

    The figures in the first image do not equate to those earlier in the day when I monitored. Then the max PV voltage was 33.4 and the max battery was 13.66 with a total wattage of 140. Not only do the figures differ but each time I viewed it I got different figures.

    <strong>Note also</strong> that the screen wiil not show all details vertically and there is no option to scroll.

  • Plymouth Battery Centre Test

    **14th -16th Jan 2018**

    I've just been informed that Batt4 is poor and has a 10% capacity, it was subsequently charged and discharged and I was told it now has 25% capacity. It is being charged again and I should pick it up this Thursday 18th

    My attempt to remedy will be to charge at 15.9v until the battery is hand hot on a good day seeing the charge current at 6amps for say 6 hours. This may have to be done four or five times to get 120Ah into a battery. Rolls states that 125&Deg; F or 51&deg;C is enough and if batteries reach that they need to be disconnected. This is around a temperate where it would be uncomfortable to leave the hand for a minute.

  • 12|1200 Inverter

    >Hi
    >
    >I have just bought an inverter form Wind and Sun UK, I called them for two reasons
    >
    >1) to find out what current the inverter takes when it is switched off and
    >
    >2) to say the manual was disappointing
    >
    >So
    >
    >1) how does switching work as it isn't a power switch that physically breaks and joins the 200A input cables,
    >
    > i) What is the rating of the dc input cables?
    >
    > ii) How are the input DC cables connected, I imagine there must be some loss?
    >
    > iii) Does the power switch, in the off position, just a break in power to a relay, that when on enables the dc circuit to work and connects the DC input.
    >
    >2) The manual says very little, maybe there is little to say, but it could state

    > i) the load in the off, as above,

    > ii) the image in the index is very poor and hardly usable and the one on your website, which isn't mentioned in the manual isn't much better. Could you send me a detailed image or is their one on the website. All I could find is a version of the manual; which I made a screen shot of and enlarged.

  • Plymouth Battery Center test

    **14th -16th Jan 2018**
    I've just been informed that Batt3 was so poor it could not even work the discharge unit, it was subsequently charged and discharged and I was told it now has 25% capacity. It is being charged again and I should pick it up this Thursday 18th

    My attempt to remedy will be to charge at 15.9v until the battery is hand hot on a good day seeing the charge current at 6amps for say 6 hours. This may have to be done four or five times to get 120Ah into a battery. Rolls states that 125&Deg; F or 51&deg;C is enough and if batteries reach that they need to be disconnected. This is around a temperate where it would be uncomfortable to leave the hand for a minute.

    **12th January**
    Took batteries 3 & 4 to Plymouth Battery Centre who left a message on 13th that both are heavily sulphated.
