Solar Panel Upgrade - Desert Fox

Yes, do it. :)

Is it easy to replace the 20-watt and install a 160-watt?

Just remove bolts and bolt the new one on?

Thanks.

What’s the wire size from the panel to the controller? And from the controller to the batteries? And both distances? Is the controller rated to handle about 14 amps?

I doubt it would fit.

If your solar system is like the one on our AF, it's a ZAMP system designed for 10A max.
So 160 is just too much for it. You would need to replace the controller too which is no big deal since the Zamp is rather mediocre at best (although it does put on a great show).

Hey thanks for the info.

I am wondering about size and if a 160 would fit.

I'll contact Northwood and ask!

Thanks again.

You should be able to install this system.

I have 400 Watts in panels and a 30 Amp Controller.
Works Great and easy install.

Install a 160 watt or 175 watt panel for each battery that you have plus a new controller and bigger wire. You should be able to find panels for $1 per watt on Amazon or E bay.

You can install a bigger system like a 160 watt without issue - the wires are big enough for it. You just need a better controller.

No need to call Northwood to ask them if a 160 watt panel will fit on the roof of you 21SW.

I will tell you, it will fit, along with probably 4 more just like it. The roof of a 21SW is big.
