    Thanks everyone, further searching on the Victron website revealed a calculator gizmo that has worked it out for me. W&KO was spot on.

    Solar Charge Controllers - Victron Energy (Then select MPPT sizing calculator, top right.)

    So, if with Ron's help I confirm my suspicions, I'll flick off an order

    And another PM to Ron sent

    Don.

    Bummer...I was going from memory. Thanks for correcting me

    The PWM regulators I have are 15 amp. That includes one on Aldi 160 watt folding panels and another on a Kings 200 watt flexible panel. I have been using a meter on them while travelling and have seen outputs as high as 11 amps. PWM regulators are quite cheap. For a better regular you could try the Korr one, which maintains a higher current when some others shut down.

    Assuming your battery is not fully charged, as you said it wasn't, if your panel is making 19.6 volts then the regulator should certainly be doing more than 2.
    Have you tried bypassing the regulator and connecting your panels directly to the battery?
    My PWM regulator is 15 amps. With 160 watt solar panels connected through an ammeter, I have never seen it make more than 11 amps, in bright sunshine.
    So, by-passing a faulty regulator is certainly not recommended, but it's also not necessarily the end of the world.

    Charger attached to portable solar panel faulty

    Not sure if it’s covered in the Victron manual.....

    When viewing history, if you tap on the bar graph you get a breakdown of the charging.

    This is with a 60L fridge running inside a locked up defender.....complete with a black roof. Outside temps >30 degrees on these day.
