5.1 The Overview of Electrical Connection
5.1.1 Electrical System Connection
The Q.HOME+ ESS HYB G2 has two solar energy inputs (PV1, PV2). 3.3kW (per string) is the maximum
output for each PV input. The AC output of Q.HOME+ESS HYB-G2 is connected to the Home Load
and the Grid. Between the Grid and PCS, the Digital Energy Meter is placed for power metering.
The Home Load is directly connected to PCS. PCS is installed between the AC circuit breaker and DC
Disconnect for safety reasons. Refer to Chapter 2.1 for detail system diagram.
The Q.HOME+ ESS HYB G2 uses the two independent channels of the PV Input ({PV1+, PV1-}, {PV2+,
PV2-}). They are used independently for running the maximum power from the sources of PV1 and PV2.
Two channels are recommended for independent use for the two PV Inputs. Make sure not to connect
one PV string in parallel with the two independent PV inputs (PV1, PV2).
A PV string must not be commonly connected to the two input terminals of the Q.HOME+ ESS HYB G2.
That is, make sure not to connect the split wiring from one PV string output with the two independent
PV inputs (PV1+, PV1- and PV2+, PV2-). (Refer to the PV String connection method in the [Figure 5-1]).
* PV modules shall have an IEC61730 Application Class A rating or equivalent.
5.1.2 Power Line Specification
As shown in the [Table 5-1], the input / output power cables correspond to the AC / DC input / output
specifications for this system. Battery Power Cable is not provided. Please prepare it seperately.
