7.3 WIRING FOR PARALLEL OPERATION
Multiples of the GP-MPPT-PRO-60 can be wired in parallel to charge the same battery bank for increased charging
current. When wired in parallel the controllers will coordinate to ensure they work together to provide as much power to
the battery bank as possib
le.
Only the battery output can be wired in parallel, the solar input of each controller must be
individually wired to separate solar arrays.
While configured for parallel operation, the built-in display, remote display and Bluetooth
dongle only relay information for the individual solar controller that they are connected to.
This means each controller will need a separate remote display or Bluetooth dongle. To get a
complete picture of the total power going to the battery bank the charge current displayed for
each controller must be added together
7.3.1 WIRING DIAGRAM
1. CONTROLLER
The controller can be used separately or in parallel operation and, when used in parallel, it needs to connect to the RS485
communication cable.
2. SOLAR PANEL
The solar panel should be connected independently with the controller, and the power of each circuit should not exceed
the rated power of the controller.
3. BATTERY BANK
A battery bank consist of several batteries possessing specific voltages and capacities.
4. RS232 COMMUNICATION INTERFACE
The RS232 connects to the PC or Bluetooth
TM
and can process information from the controller offering real-time
monitoring and other functionality.
5. RS485 COMMUNICATION INTERFACE
The controller must be connected to the cable in order to achieve a parallel operation.
