Do I Need a Fuse Near the Batteries.

I'm useless at electrics but have bought a couple of 20W Solar Panels to go into a dual controller then onto the new batteries. One is a "house" battery (lights,GPS,fridge etc) the other an engine starter battery for the boat.

Do I need fuses close to the battery?

I realise now I don't need diodes as I have the regulator and ignore the extra negative lead.

I can't see why you can't have a similar set up with solar panels on the roof/bonnet of a Defender to keep fridges lights etc topped up or maybe people do...

Would put a fuse near battery just in case of a direct short ! Saves having a fire

Can you tell the make and model of your regulator/ controler, and i this has tw isolated output for each battery otherwise
you seem to be conecting in parallel the batteries with a small section cable.

I say small section cable as thoses panels will produce up to arround 3.3 Amp.

Cheers

Souinds as though I may need fuses.

This is the controller

I will probably wire one panel up to the other so that only one lead goes into the controller!

Sunstore are supplying the cable also. Good thick stuff apparently.

These are the panels...

Glad I got it right Luismi, thanks. A couple of fuses and job done then

I don't think the rest of the switchboard has fuses though so that will keep me busy

Hi Zag, study your swichboard carefully... At first I thought also my boat switchboard did not have fuses, but then I discovered the switches were with incorporated automatic fuses! Those american boat builders were way ahead 40 years ago
