6.5 Double MPPT of the Growatt UE
6.6 Communication and monltor
The Growatt UE includes dual input section to process two strings with independent
MPPT, high speed and precise MPPT algorithm for real-time power tracking and
energy harvesting, as well as transformerless operation for high performance, the
max conversion efficiency is up to 98%. The wide input voltage range makes the
inverter suitable to low power operation as well as the high power operation.
As the weather influence and the location of two MPPT PV arrays different, the
power of the MPPT A inputs is different from the power inputs of the MPPT B at the
same time, the Growatt UE works at a non-symmetrical input state. But the MPPT
algorithm of the inverter makes it tracking the maximum power point of every MPPT
channel to improve the energy utilization of the PV arrays.

6.6.2 Monitor the inverters
The inverter provides RS485 interface and RS232 interface to communicate with
remote PC or logger. User can monitor the inverter state via the following types of
communication systems.
You can update firmware via RS232 or RS485*
Active power control with a ripple control signal receiver
