2.4 PV Connection
The inverter has two PV inputs and can be configured in independent mode or
parallel mode. Refer to the user manual for mode selection.
Before connecting the PV arrays to the inverter, ensure that the
impedances between the positive terminals of the PV string and Earth,
and between the negativ e terminal of the PV string and Earth are larger
than 200 kOhm.
The inverter will not function properly if the DC polarities are reversed.
Check the positive and negative polarities of the PV cells.

2.7 DO Connection
The inverter has two DO relays with different functions as follows:
DO1: Consumer load control. Please choose the appropriate contactor
according to the load power, e.g., the contactor types of the 3TF30 series
from SIEMENS (3TF30 01-0X). The relay is activated once the conditions of
the control mode are satisfied.
DO2: Earth fault alarm. Once the inverter receives the earth fault signal, the
relay closes the contact. The relay remains triggered until the fault is
removed.

For example, with a total maximum installation capacity of 4600 W (SH4K6), the
export power should be set to 3220 W (i.e. 4600 * 70 %).
Export power range:
When the existing system is disabled, the range is from 0 to the rated
power of the hybrid inverter.
When the existing system is enabled,
− the lower limit is the rated power of the existing PV system.
− the upper limit is ([rated power of the hybrid inverter] + [rated power of
the existing PV system]).
− the value will synchronize with the settings for retrofitting an existing
system.
Reactive power regulation:
OFF:
The reactive power regulation function is disabled.
The power factor (PF) is limited to +1.000.
“PF” mode:
The inverter is capable of operating with fixed power
factor.
The PF ranges from 0.8 leading to 0.8 lagging.
Leading: the inverter is sourcing reactive power to the
grid.
Lagging: the inverter is sinking reac tive power from the
grid.

If the battery type or capacity setting is inconsistent with the actual, the
charge/discharge current may be less than the actual charge/discharge ability.
However, the system can operate normally. Proceed as follows to modify.
1. Stop the inverter via the LCD menu.
2. Reset the battery type and parameters. Proceed as follows to enter the
submenu.
3. Start the inverter via the LCD menu.
