    Morning Low :: ≥ 12.63 | < 12.63 | < 12.39 | < 12.03     Yield :: ≥ 900 | ≥ 540 | ≥ 230 | ≥ 100 | ≤ 90
    Morning Low is the voltage before any use, maybe before sunrise :)
    Yield is the power used including power via the inverter. ~  I  Indicates Inverter Use (Fridge + +)

  • MPPT 150|60 Set-Up

    May 9th Initially the controller default programme is the lowest, so I have now set it to option 4. The nominal voltage then is 14.9v and tested at 15.1 probably due to temp compensation, which has to be set.

    page 9 of manual showing pre-programmed options

    Sept 2020 I transferred Victron Direct USB cable to set up the S6 145s workshop batteries way back, probably in May, but I now have a second unit that will be fitted as and when

  • Voltage Drop

    Javascript calculator for voltage drop through copper wiring/cable

    • Cable length is the single distance from source to load not the sum of the pos. and neg. wires.
    • Use a figure for maximum current as this calculates the maximum voltage drop.

    Select the conductor size in mm2 :   Cable length to the load in metres:

    Supply voltage:   Maximum current draw in amps:

    Load voltage =   Drop as a % of supply Voltage =

     Voltage lost in cable =    Wattage lost in cable =

  • Connection and Junctions

    For a simple connection the best option is a ceramic connector, though there are limited options:~ Either a two or three way block and max cable of 4mm^2 (30A)
