Hi:
Having both connected will work the way you want, only if you make sure
the solar charger charging voltage is higher than the Kohler charger
voltage.
When the solar charging source has higher voltage it will trump the lower
Kohler charging voltage an do the charging when the sun is out. When the
sun is not out, the Kohler will do the job.
However, if the solar charging source is never higher, the solar charger
will not be able to create any charging current as it will always see an
already high battery terminal voltage as maintained by the Kohler.
If there is no charging voltage adjustment on the Solar or Kohler charger,
you could put one, (or more as required) diodes, in series on the Kohler
charging wire to drop its voltage enough to make sure the solar charger
voltage is slightly higher.
The diodes could be anything as long as they can handle the full charge
current from the Kohler.

[RE-wrenches] Generator brains
Sent by:

Wrenches,
We recently discussed the significant load the brains of many
gensets requires, especially in off-grid. I have been trying to keep the
start battery and brains of a Kohler 14KW gen charged with a ~40 PV. This
works fine until the winter.
Any issues with keeping that PV connected (with its charge
controller) and re-connecting the supplied-by-Kohler power source
connection
to keep the battery and brains happy? I would like to think the PV would
take some of the load off the AC connection to the main off-grid system,
with no conflicts.
TIA
