Standard vs. Australian Default Settings

Post by Robert Ibe »

Can someone explain this. Why are the float and equalize voltages different in Australia ??? Does electricity somehow defy physics and work differently down under.

page 101 fm60 manual

Standard vs. Australian Default Settings
Several version settings are available for the FLEXmax upon initial setup. These can be
selected upon initial power-up. (See page 17.) The English and Spanish versions have the
same standard default settings; however, the Australian version has certain default settings that
are different

It is not specified in the manual why there a slight difference of .2 to .4V on the Float side and the Equalizing voltage.
One possible reason is Australia is located in the Southern hemisphere. Might be related information ---> in Australia you orient your solar panels facing north, instead of facing south as we do here in the northern hemisphere.
It is also stated in the manual that there are no differences in performance and efficiency between the 2 versions. So feel free to just use the US version. The latest app notes regarding new battery types like lithium ion types do not include an app note separate for Australia, anyways.
If others have more information, please chime in ;-)

It's widely held that a greater Float tension is required because Australia is an island, and all that lead poses a clear and present danger of sinking. This, however, is patently false.

While the source of the reasoning behind the Float differential has been lost in the mists of time, its believed to have its origins in the Middle Ages with the progenitors of the modern denizens of Oz: https://youtu.be/zrzMhU_4m-g

Well, we had a supposedly highly educated Congress critter ask the question, (paraphrasing..)

If we put more troops and equipment on Guam, is there a danger the island may flip over?

The look on the face of the military brass was exquisite..
Information, you get not; if incorrect question, you ask..

Sorry OP. This is a world record for a legit post going off the rails.

I know I'm late to the party but when I saw this post I remembered a reference to the different AU settings in my old MX60 manual, which I still have. FWIW, copy of the relevant page attached - unfortunately, no explanation offered.

Just a guess, but maybe it has something to to with what they expected the usual average ambient temperature to be in Aus?

I was wondering that too, but wouldn't the higher temperatures argue for lower voltage settings? Especially Equalization, which is not temperature compensated. Also EQ time goes from default 1H to 3H.

Those seem like settings for the Antarctic.
