6.4.4 Power display
The power and energy of the inverter are displayed in three fields: Power, Day and
Total. The display is updated every five seconds.
Power
The power is that the inverter is currently feeding into the electricity grid.
Day
The energy fed into the electricity grid on this particular day. This equals the energy
generated from the inverter's start-up in the morning to the current time.
Total
The total energy is that the inverter has fed into the electricity grid during its entire
operating time.
Measurement accuracy
The display values may deviate from the actual values and must not be used for
billing purposes. The inverter's measurement values are required for the operational
control and to control the current to be fed into the electricity grid. The inverter does
not have a calibrated meter.

6.5 Double MPPT of the Growatt UE
6.6 Communication
About the software of shinebus and the usage of it please download from the web:
www.growatt.comchannel to improve the energy utilization of the PV arrays.
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.
