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.

Energy meter
Two 1-phase bi-directional energy meters are needed. One is for grid data collection, another is for PV
inverter data collection. With the meter data, the GEatom 103KHF decides when to charge/discharge
the battery packs.
2.2 System Connection
The four main components are connected as displayed in Figure 1, which can not only optimize solar
energy self-use and realize peak shaving, but also protect family from power outages.

Attention: The nominal current of meter is only 20A. If the power of load and emergency load is
larger than 4.6kW, the system is recommended to change a meter with CT as
Figure 4
to avoid from
current over range.
