Programming the MPPT
All settings are for 12 Volt nominal systems.
Divide the required settings:
/ 2 for 24 Volt Systems.
/ 3 for 36 Volt Systems.
/ 4 for 48 Volt systems.
Eg: If the float voltage for a 48V system is 54,2V, the setting on the MPPT = (54,2/4) =13,8V
Set the float voltage on the MPPT to 13,8V
Please consult your battery supplier for the correct battery charging specifications before
commencing with the MPPT programming. Incorrect charging can damage batteries. Make
note of the following:
Battery float voltage, boost voltage
and equalisation voltage. Note that some battery types cannot
be equalised.
Programming mode
To enter the programming mode the MPPT must be
connected to the batteries:
The
Battery Circuit Breaker
must be turned
ON
The
Panel Circuit Breaker
must be turned
OFF
.
When the Panel circuit breaker is turned off the
MPPT will enter the sleep mode and the MPPT must be in
SLEEP MODE to enter the programming mode
Press and hold the <

Float Voltage
The Float voltage can be changed from 12.4 to 14.5 volts in
0.1 volt increments per 12V battery pack.
Default Value is 13.8V.
Obtain the correct float charge voltage from your battery
supplier
Example: For a 48V battery bank with a float voltage of 55.2V
the setting on the MPPT must be set at 13,8V
