    In simple terms they are later technologicly and are reputed to be far superior in converting your solar power to battery power:thumb:
    Ie More bang for your buck with less loss

    What I dont like about than one is the display is on the end and wont be user friendly if fitted normally to a wall. Much prefer a face display

    We only now use the Victron MPPT unit. We have tested it and concur with the claims of about 30%:Eeek: more efficient

    On my own van I have experimented extensively and have three 130W panels which I have (and still am) used a "mix and match" approach to establish the best "bang for my buck"

    We are in the process of setting up a panel on a stand that we can wheel in and out of our shop wired to a normal regulator and a MPPT regulator via and Amp meter. That way we can show the difference as the meter will show the cumulative effect.

    The MPPT controller is more efficient at lower voltages from the panel, such as in low light conditions frequently found in the UK. You won't see much difference at midday in Spain in August.

    I have always been a bit dubious about the flexy panels though, as without an air gap under them they could get very hot in bright sunshine, with the potential of damage to the panel.

    I wouldn't touch a PWM controller. MPPT is the way to go.
    Here is a youtube video showing why.

    I also would if I had the money use 100% victron gear. It is the best.
    But even an el Cheapo chinese MPPT charger will give you some gains over any PWM controller.
