FOX-D1 & FOX-D40 solar panel equipement function?

[Nicholas123]

I have those two units along with a Sunware solar panel on my boat but I don't know much about them because the operational documentation that came along with them is all in Dutch.
Yesterday I was a bit alarmed to see that the readout was touching 14 volts,does this mean that it is frying my battery?
If somebody could explain their basic function I would be very grateful.

Not at all. That's a moderate charging voltage for a 12v battery.

You can download a manual in German and English for the Fox-D1 from https://www.sunware.de/sunware/produkte/regler_detail/FOX-D1

Well I checked my battery with my ALDI battery & alternator testing device yesterday & it put the voltage at somewhere between 13 & 14.5 volts (the 14.5 sector was just flashing that is one measure away from the red flashing light) :ambivalence:

I'm wondering how I can be sure things are working as they should be because I shorted the D-40 thing blowing a fuse?

Thanks very much for that.It has given me a better understanding of how it works & an alternative wiring diagram :ambivalence:

I had a Fox-D1 on my boat until last weekend, and I don't have a clue how it worked. When set to display current it seemed to show current into or out of the battery reasonably accurately ... but it was only connected to a separate feed from a solar panel, and so shouldn't have been able to see any current going out the standard way, or provide a route for it.
