Auto The BatChargMode parameter allows you to over-
ride the Auto charge mode of the inverter.
Auto:
Inverter maintains charge automatically.
Selecting any of the other modes will automatically
place the inverter into that mode. For example, if
you wanted to perform an equalize charge on your
flooded batteries, you would select Equalize in this
menu to put the inverter into equalize mode.
For details about the special charge modes see
"
Battery Management
" on page 88.
Manual:
For future use. Please do not select.
Autostart Off,
On
Off The Autostart parameter allows the inverter to start
automatically whenever DC power is applied to it or
after a fault has been detected (up to 10 times). If
AutoStart is OFF, the inverter will always have to be
started manually.
BaudRate 1200,
2400,
4800,
9600,
19200
1200 The BaudRate parameter selects the baud rate that
the Sunny Island 4248U will use to communicate
with external devices.
ParameterSet None,
Load,
Save
None The ParameterSet parameter allows the current set
of parameters to be saved, or a saved set of param-
eters to be loaded.
Select
None
to operate the inverter with the current
set of parameters.
Select
Save
to save the current set of parameters
(When the system is operating optimally, it is a
good idea to save that set of parameters. This is
particularly useful when experimenting and the
inverter needs to be restored to the previous set-
tings.).
Select
Load
to load the saved set of parameters into
the Sunny Island 4248U
Splitphase None,
Master,
Slave
None The Splitphase parameter selects the role each
inverter has to play when used in split-phase mode.
This parameter should remain set to
None
unless
the inverter is to be used in Split-Phase mode. (See
Split-Phase section for details).
