3.4 Electrical Connection
3.4.1 Connection to Grid (AC Side Connection)
(
1) Check the grid voltage and frequency, select a suitable safety standard from inverter that comply with this requirements.
(
2) Add breaker or fuse to AC side, the specification should be more than 1.25
times of rated AC output current.
(
3)
The
PE
line
of
inverter
should
be
connected
to
the
earth
,
make
sure the impedance of neutral wire and earth wire less
than 10 ohm.
(
4)
Disconnect the breaker or fuse between the inverter and the utility.
(
