HI,
I have a Rapido with a 120w panel with a PWM 10 amp regulater fitted from new, if i added another 120w panel would the reg size have to be increased to say 20 amp, i have been told it would be ok as is but i am not so sure.
Many thanks in advance
Bill

Yes you will need a 20 amp regulator as a single 120 w panel can produce up to 8 amps. Also worth paying a bit more for a good quality MPPT regulator to get the most out of your panels.
