Solar Panel regulator size

I am going to fit 3 x 80 watt solar panels to my new van and possibly on one and would like some advice on size regulator I would need to cope.......
 
Hi,

I would suggest a 30A regulator to be safe. Have a look in that well known internet auction site ;)
 
2It depends on your output from the panels. Check on the panel spec but it is usually 5 amp max from a 80-90W panel. So for three, anything 20-30A should be OK. Put a 15 or 20 A fuse in the panel side of the circuit.
