What size fuses

[kontikimark]

Hello to the brains
Just purchased a renogy 20amp MTTP with a 100watt panel using 6mm cable. I wish to protect from panel to controller and from controller to battery.
I was thinking 10amp from panel to controller and 20amp from controller to battery is this correct?

You don't need one on the input to the controller & if you only have one 100 watt panel a 10 amp fuse will be fine on the output.

Thank you Lenny

I fitted one before the controller so that I can isolate the solar panel at any time.

Pardon our interruption...
