2.4 Retrofitting the Existing PV System
The SH5K-20 hybrid inverter is compatible with any single-phase PV
grid-connected inverters. An existing PV system can be retrofitted to be a PV
ESS with the addition of SH5K-20.
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
SH5K-20, the self-consumption of the new system will be greatly improved.

PV inverter. The output power of the existing
PV inverter should be taken into
consideration for export power setting. For
