Switch to change solar from Battery to powerbank

[Craiggg73]

Looking to add solar panel to roof that connects to leisure battery but has a switch that i can use to direct it to my allpowers power bank. Already have the power bank which i use for charging my E-bike. Any ideas on a suitable switch?

Would something like this work?

I used the same change over switch. Only issue I had was with the fork type spade connectors used. I found I needed the yellow size for the cable diameter but this was tight for the switch aperture.
You could forgo the crimp ends, I thought it made a neat job without the odd strand of wire poking out.

If you sisconect the battery with that without isolating the panels then you will nacker the regulator, dont do it.

Don't think so Trev, it's the right side of the MPPT isn't it?

You must either keep a battery in link or disconnect the solar input to mppt unit unless you cover the panel, my unit has a fuse to disconnect.

I thought that as long as the battery is connected to the MPPT you can disconnect/connect the solar as you please?

Correct Rob, just dont disconnect the battery without cutting the solar to regulator.
