2.9 Retrofitting the Existing PV System
The hybrid inverter is compatible with any three-phase PV grid-connected inverters. An ex-
isting PV system can be retrofitted to be a PV ESS with the addition of the hybrid inverter.
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.
