voltage than the solar panel. The solar power will be the primary supply and AC will be the
secondary supply if the solar panel has a higher output voltage than the AC-to-DC source.
The
12V
output
terminals
are
for
powering
a
data
logger

Each
battery
family
uses
a
unique
charging
algorithm
to
calculate
the
best
charging
voltage
for
battery
temperature.
The
algorithms
use
the
charger
temperature
as
the
default
temperature
source.
If
the
charger
and
battery
are
in
the
same
enclosure,
the
two
temperatures
will
be
similar.
If
the
battery
will
be
in
a
separate
enclosure,
place
a
temperature
sensor
on
or
near
the
battery
and
use
the
appropriate
SDI-12
or
RS-232
command
to
send
this

The

can
send
data
to
the

to
observe

and
possible
problems.
It
can
also
be
configured
to
work
with
a
wide
range
of
batteries
and
input
power
supplies
and
test
the
existing
battery
system
for
possible
shorting
and
sulfation
problems.
The
CH201
can
be
used
without
any
configuration
or

To
take
advantage
of
the

SDI-12 data logger programming is usually simpler than RS-232 programming. Also, multiple
