    As I understand it the Ctec takes both as inputs but limits the output to that of the DC to DC charger, whereas the solenoid will allow both inputs to go to the battery. BUT the battery will restrict the input depending on it's state of charge.

    I use up to 3 x 105 Ah batteries at the back. When it is down to 50 % they will charge at almost 40 A each
    You will store 90 A plus in the first hour of driving. That is what I call reaction.
    2 cables to the back 32mm each. (Industrial solenoids)
    Batteries last 8 years plus.
    I really would like to have an alternator and cabling such as yours. Wow 120A to batteries and also supplying your fridges and car. Amazing....

    Thatís exactly what I said in my post defending you. And my opinion was independent of this paper, based on my own solid knowledge and experience.

    Unfortunately I was shut down by somebody who canít read and launched a viscous attack accusing me of all manner of irresponsible behavior and laying responsibility on me for vrot food and warm beers.

    So I just left the debate.

    Good to see that an AGM can be used with solenoid with great success.
