Figure 1 GHESS 3.7-4.8-SL hybrid system
The system includes three modules: Powervortex 3700TL hybrid inverter, lithium battery packs
and energy meter.
A
B

Figure 2 Main system components
A - Powervortex 3700TL hybrid inverter
The hybrid inverter converts the DC power generated by PV modules into AC power. The
generated electricity from PV is used by the household loads, charged into the battery packs or
fed into the grid .
B - Battery packs
Battery packs stores the energy generated from PV generator. Generally each battery
module’s capacity is 2.4kWh; so two battery modules can constitute 4.8kWh battery pack.
C - Energy meter
The 1-phase bi-directional energy meter is for data collection and communication. With the
meter data, the hybrid inverter decides when to charge/discharge the battery packs.
