Adapting the module power to the solar controller
Strictly ensure that the module power matches the solar controller used!
If you have a module voltage which is significantly higher than the battery voltage, the charging current of the battery will be
higher than the given maximum current of the module due to the MPPT function. Example: A module with 36V and 5A charges a
12V battery with max. 15A. This means that an MPPT
plus
+
20 A must be used for this module.
Attention: If you use a solar controller whose charging power is too low, the solar controller may be damaged in the
long run!

Device addressing
The MPPT
plus
+
series
offers the option to control a total of 4 devices simultaneously via a touchscreen remote control (FB-
04/FB-05) or a webbox LCD. For this purpose, all the devices used must be connected with each other via the USB interfaces
and a unique address must be assigned to the respective device. The addresses are assigned via the DIP switches 1 and 2 on
the back of the device.
The following addresses will be assigned:
DIP switch 1
DIP switch 2

Note: A simultaneous use of webbox LCD and FB-04/FB-05 is not possible!
Standby function
If the standby function is activated, the MPPT
plus
+
switches to standby mode after approx. 20s when no or insufficient voltage is
applied on the solar input. In this case, the own power consumption is <10 mA.
The power supply of the USB interface is also switched off, so that externally connected devices being supplied with power via
the USB connection are no longer functional.
If sufficient solar power is applied, the device switches automatically and immediately from standby mode to operating mode. In
this case, the solar voltage must be higher than the battery voltage. The button
"Consumer on/off"
can be used to reactivate the
device manually.
