• Basic configuration

    The Electric Control brings together the inputs from solar panels via terminal, where adjustments can be made, to charge controllers that feed the batteries. The main update for 2018 is the terminal blocks that allow the solar panels to be connected separately to two banks of batteries, and be connected in parallel or series and bypass the controllers to fed the batteries directly.

  • Battery Loads

    1. Router 0.35A | Computer 0.4A | LEDs (7W 0.3, 4W 0.2, 1W 0.05)A
    * Computer charging screen battery and running 6W
    * Samsung III 5W
    * Inverter with audio amp and standard plugs 40W

    With all powered on, current draw is 1.2A: so for 8 hour is 96W is used.

    Solar panels can produce 250w per hour so in the summer one hour will provide more than double than and there is less used.

    **Feb 5th-6th** Left router on for 24hrs and 50W used
    **Feb 24th-25th** Left router and camera on for 9hrs and 70W used

    ### 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
