2.8 Retrofitting the Existing PV System

The hybrid inverter is compatible with any single-phase PV grid-connected inverters.
An existing PV system can be retrofitted to be a PV Energy Storage System with the
addition of SH3K6 / SH4K6.

The power generation from the existing PV inverter will be firstly provided to the
loads and then charge the battery. With the energy management function of the
hybrid inverter, the self-consumption of the new system will be greatly improved.

Zero-export (Partial):

According to the local regulations in Germany, please
set the export power to 70 % of the installation
capacity.

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 %).



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 reactive power from the grid.

When the grid voltage or frequency
reaches the recovery value, the
corresponding fault code displayed on
the LCD will be cleared and the inverter
can start operating.

Power Ramp Rate: the ramp up/down rate of power variation.
The power rate limit mode is enabled (ON) by default.
Set to OFF to turn off the function.

The inverter will automatically disconnect from the grid within
3 s when the average voltage for a 10 min period exceeds the
set-point of 10-min Over Vtg.
Set to OFF to turn off the function.

Reconnection time (Italy only):
A reconnection to the network can take place only if the
voltage is between 85 % and 110 % of the nominal value and
the frequency is stably maintained in the range of 49.90
Hz–50.10 Hz.

The reconnection operation will be allowed if the frequency and voltage are stable in
the reconnection time of 300 s if is to be performed with a Gradient positive power not
exceeding 20 % * (maximum power) per minute.
