keywords: Retrofit system settings for SHxxRS inverter (What is a Retrofit system and how to set it)

The system formed after adding an energy storage inverter to the photovoltaic power generation system is called Retrofit system. That means, there is not only PV inverter but also hybrid inverter in the transformed system, as shown in Figure below.

1. Set the parameter 16-Rated Power of Original Power Generation Systems. Note that parameter 16 refers to the installed power rather than the rated power.

2. Set Feed-in Limitation Value = (Installed PV Power + Rated Power of Original Power Generation Systems) × Feed-in Limitation Ratio.

If the system is not a transformed system, there is no need to set parameter 16, and the default value is 0.

Special attention:

1. When only the PV inverter is connected to the PV modules and the hybrid inverter is not connected to the PV modules in the transformed system, the Installed PV Power should be set to 0.

2. The communication of the smart meter must be connected to the Hybrid inverter.

Note: To avoid battery draining in production for self-consumption mode, please turn on Forced Charging and set Forced Charging Start Time, Forced Charging End Time and Forced Charging Target SOC according to customer requirements.

This manual is intended for professional technicians who are responsible for installation, operation, maintenance and troubleshooting of inverters, and users who need to check inverter parameters. The inverter must only be installed by professional technicians.

The professional technician is required to meet the following requirements:
