Theoretical question.

If I had three 12v rated solar panels but wanted to use them in conjunction with a 24v battery bank is it possible or would I need an even number of panels for this?

Thanks

Del.

They would need to be used in pairs.
Unless a high end MPPT controller was used. ie: MX-60.

Thanks Ghurd,

MPPT?

I've got a Steca PR3030 that I'll be using. I'll have a look through the instructions.

Thanks Ghurd, I'd been reading the controller manual tonight and came to the same conclusion.

Cheers

Del.
