5.1 The Overview of Electrical Connection
The 3.6 kWh All In One has two solar energy inputs (PV1, PV2). 3.3 kW (per string) is the
maximum output for each PV input. The AC output of All in One is connected to the Home
Load and the Grid. Between the Home Load and the Grid, the Digital Energy Meter is placed
for power metering. The AC circuit breaker and DC Disconnect switch in the distribution box
are installed between the All in One for safety reasons.
As shown in the [Figure 5-2][Figure 5-2: PV connections], the 3.6 kWh All In One 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). (Refer to
3.6 kWh All In One Solar energy input connection in the [Figure 5-2]).
A PV string must not be commonly connected to the two input terminals of the All in One
system. 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 5-2]).
