Well that makes sense. Thank you for your time and your well thought out
answer.
I was hoping somebody might say a solar trickle charger wouldn't be strong
enough to hurt anything, but I don't know squat about electricity. I swear, the
more I study it the more complex and confusing it becomes. Not to mention, it
can be fairly mean when handled wrong.
Thanks again.

David does in fact drive a fuel injected bus but it doesn't have a computer
(EMP-proof, oh wow!). However, David knows enough about electronics to
realize that a solar trickle charger is not going to affect any part of the
FI VW's electrical system to the extent that an alternator would and
therefore should be completely safe. This is assuming that the charger is
regulated and will not raise the battery voltage above what the alternator
would (about 14V).
Keep in mind that what the manual says is by necessity painting with a very
broad brush. Would I have a gas station hook up their 100-amp wall-powered
quick charger to my FI bus's battery without disconnecting the cable first?
No way in hell. But a solar trickle charger? Should be no problem at all.
Also keep in mind that the VW engineers were a pretty smart bunch and they
were not going to design a computer for an automobile that was so fragile
that it can be damaged by really small variations in voltage. If that were
not true you would not have 30+ year old busses running around with
their original electronics. Give them some credit.
Of course I am just one person with one opinion, just like Bill Gmail. And
I only stated it because I was asked. :-)

Does David drive a fuel injected bus? I do and will follow the factory
recommendation. No chargers for me unless the battery is disconnected
