2.3 Retrofitting the Existing PV System
The SH5K 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.
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, the self-consumption of the new system will be greatly improved.
